DETAILED DESCRIPTION


FIG. 1 illustrates a system 100 configured for detecting a sitting duck scenario of a vehicle on or near a road, the vehicle being operated by a vehicle operator, in accordance with one or more implementations. As used herein, the term “sitting duck” may refer to a vehicle that has been stationary continuously for at least a specified duration (in some implementations of at least five minutes) on or within a particular proximity of the nearest road. Additional conditions to specify this term may be considered within the scope of this disclosure. In some implementations, the vehicle's engine may be on or off. Typically, vehicles stuck in traffic or parked legally are not considered as sitting duck. In some implementations, the term “shoulder” of a road may be defined as an emergency stopping lane, typically on the right of the right-most lane in countries that drive on the right, and typically wide enough to accommodate a stopped vehicle without impeding the flow of traffic. Vehicles in a lane, on the shoulder of the road, and/or partially in a lane and partially on the shoulder may be considered as sitting duck. In some implementations, a sitting duck scenario may be caused due to a vehicle being out of fuel. In some implementations, a sitting duck scenario may be caused due to mechanical and/or electrical malfunction. In some implementations, a sitting duck scenario may be caused due to a collision and/or other accident. In some implementations, a sitting duck scenario may be caused due to a change of drivers, a driver sleeping, resting, and/or taking a break, and/or other circumstances initiated by a driver. Other causes and combinations of multiple causes may be considered in detecting a sitting duck scenario. From the perspective of a driver, truck owner, fleet manager, and/or other stakeholder, vehicles in a sitting duck scenario may be at risk, e.g., due to other traffic. Accordingly, system 100 is configured to detect these scenarios and provide notifications (e.g., warnings) related to these detected scenarios. In some implementations, a vehicle that uses system 100 may be configured to take certain actions responsive to these detected scenarios, as described elsewhere in this disclosure. In some implementations, system 100 may include the vehicle itself, whereas in other implementations system 100 may exclude the vehicle itself.


The roads vehicles are on or near may include public roads, private roads, and/or other types of roads. By way of non-limiting example, the types of public roads may include highways having one or more traffic lanes heading in one or more directions. Individual roads may head into one or more directions of travel. In some implementations, the roads may include one or more traffic lanes in each direction of travel. Traffic lanes may be intended to include vehicular traffic. In some implementations, individual roads may have (direction-based) centerlines between traffic lanes heading in opposite directions. In some implementations, individual roads may have (geometry-based) centerlines in the geometric center of all the traffic lanes that form the entire road in all directions. In some implementations, highways may have controlled entries and/or exits, such as (metered) on-ramps and off-ramps. In some implementations, highways may have a dividing strip between traffic in opposite directions. In some implementations, highways may have certain speed limits, such as, for example, at least 40 mph, at least 45 mph, at least 50 mph, at least 55 mph, at least 60 mph, at least 65 mph, and/or other ranges of speed limits. In some implementations, highways may be characterized by a lack of traffic lights. In some implementations, the classification of whether a road is a highway may be under government control. In some implementations, the classification of roads may include roads being classified as primary roads, secondary roads, rural roads, city roads, and/or other types of roads. For example, a government-controlled entity may provide road-specific information, e.g., an online database, that includes the types of road for multiple roads in a particular geographical area, such as, by way of non-limiting example, a state, a county, a city, a municipal entity, and/or other particular geographical areas.


In some implementations, system 100 may include one or more of servers 102, electronic storage 130, a set of sensors 108, network(s) 13, client computing platform(s) 104, external resources 128, a remote computing server 129, and/or other components. System 100 and/or components thereof may be carried and/or otherwise supported by one or more vehicles (e.g., a first vehicle, a second vehicle, a third vehicle, and so forth), including but not limited to a vehicle 12. Operation of system 100 may be described in the context of a particular vehicle, e.g., vehicle 12, but this is not intended to be limiting. In some implementations, system 100 may detect sitting duck scenarios for a fleet of multiple vehicles. In some implementations, individual vehicles (e.g., vehicle 12) may carry and/or otherwise support system 100 and/or components thereof. Server(s) 102 may be configured to communicate with one or more client computing platforms 104 according to a client/server architecture and/or other architectures. Client computing platform(s) 104 may be configured to communicate with other client computing platforms via server(s) 102 and/or according to a peer-to-peer architecture and/or other architectures. Users may access system 100 via client computing platform(s) 104.


Individual vehicles may include a set of resources for information gathering, data processing, and/or electronic storage, including but not limited to persistent storage. Individual vehicles may include sensors (e.g., set of sensors 108 configured to generate and/or otherwise gather data, such as output signals). In some implementations, individual vehicles may be configured to detect vehicle events, e.g., based on output signals generated by set of sensors 108. As used herein, the term “vehicle event” may include occurrences of events involving one or more vehicles. As such, detection of vehicle events may include gathering information by monitoring the operation of one or more vehicles, including but not limited to information related to current or past vehicle speeds, current or current location, and/or other information pertinent to detecting of vehicle events, particularly occurrences of sitting duck scenarios.


In some implementations, operation of vehicle 12 may be actively and primarily controlled by a vehicle operator (i.e., a human operator). In such a case, a non-human vehicle operator may take over (or be requested to take over) control of the vehicle in certain circumstances. In some implementations, operation of vehicle 12 may be actively and primarily controlled by an autonomous driving algorithm (also referred to as an algorithmic vehicle operator, or a non-human vehicle operator). In such a case, a human vehicle operator may take over (or be requested to take over) control of the autonomous driving algorithm, e.g., responsive to extreme and/or unconventional driving scenarios, or responsive to a failure or error-condition of the autonomous driving algorithm. In some implementations, a human vehicle operator and an autonomous driving algorithm may form a team that controls operations of vehicle 12 together.


Set of sensors 108 may be configured to generate output signals conveying information related to (operation of) vehicle 12, a location of vehicle 12, a vehicle operator of vehicle 12, and/or a context of vehicle 12 (e.g., related to the surroundings of vehicle 12). In some implementations, set of sensors 108 may be carried by vehicle 12. In some implementations, one or more sensors in set of sensors 108 may be external to vehicle 12, such as roadside sensors, sensors embedded in the surface of a road, sensors carried by other vehicles, and/or other sensors. Although set of sensors 108 is depicted in FIG. 1 as a single element, this is not intended to be limiting. In some implementations, set of sensors 108 may be configured to generate output signals continuously, in an on-going manner, and/or at regular or irregular intervals during operation of vehicle 12.


Information related to the operation of vehicle 12 may include feedback information from one or more of the mechanical systems (not shown in FIG. 1) of vehicle 12, and/or other information. The mechanical systems of vehicle 12 may include, for example, the engine, the drive train, the lighting systems (e.g., headlights, brake lights), the braking system, the transmission, fuel delivery systems, and/or other mechanical systems. The mechanical systems of vehicle 12 may include one or more mechanical sensors, electronic sensors, and/or other sensors that generate the output signals (e.g., seat belt sensors, tire pressure sensors, etc.). In some implementations, at least one of sensors 14 may be a vehicle system sensor included in an Engine Control Module (ECM) system of vehicle 12.


In some implementations, set of sensors 108 may generate output signals conveying information related to a vehicle operator of vehicle 12, such as visual information, motion-related information, position-related information, biometric information, medical information, and/or other information. In some implementations, set of sensors 108 may include one or more sensors configured to generate output signals that convey information related to biological activity of the vehicle operator. In some implementations, one or more sensors may be wearable by the vehicle operator. In some implementations, one or more sensors may be placed in physical proximity to the vehicle operator to facilitate monitoring the biological activity of the vehicle operator. The information related to the biological activity of the vehicle operator may include heart rate, respiration rate, verbal expressions, responses to conditions in the physical environment in and/or around vehicle 12, and/or other characteristics of or information about the vehicle operator.


In some implementations, set of sensors 108 may generate output signals conveying information related to the context of vehicle 12, such as information related to the environment in and/or around vehicle 12. The vehicle environment may include spaces in and around an interior and an exterior of vehicle 12. The information related to the context of vehicle 12 may include information related to movement of vehicle 12, an orientation of vehicle 12, a geographic position of vehicle 12, a spatial position of vehicle 12 relative to other objects, a tilt angle of vehicle 12, an inclination/declination angle of vehicle 12, and/or other information. In some implementations, the output signals conveying the information related to the context of vehicle 12 may be generated via non-standard aftermarket sensors installed in vehicle 12. Set of sensors 108 may include, for example, one or more of an image sensor, a camera, a video camera, a microphone, an accelerometer, a gyroscope, a geolocation sensor (e.g., a Global Positioning System or GPS device), a radar detector, a magnetometer, lidar (e.g., for measuring distance of a leading vehicle), an altimeter (e.g. a sonic altimeter, a radar altimeter, and/or other types of altimeters), a barometer, a magnetometer, a pressure sensor (e.g. a static pressure sensor, a dynamic pressure sensor, a pitot sensor, etc.), a thermometer, an inertial measurement sensor, a tilt sensor, a motion sensor, a vibration sensor, an ultrasonic sensor, an infrared sensor, a light sensor, a depth sensor, an air speed sensor, a ground speed sensor, an altitude sensor, medical sensors (including but not limited to blood pressure sensor, pulse oximeter, heart rate sensor, etc.), degree-of-freedom sensors (e.g. 6-DOF and/or 9-DOF sensors), a compass, and/or other sensors. As used herein, the term “motion sensor” may include one or more sensors configured to generate output conveying information related to position, location, distance, motion, movement, acceleration, and/or other motion-based parameters. Output signals generated by individual sensors (and/or information based thereon) may be stored and/or transferred in electronic files. In some implementations, output signals may be transferred as one or more streams of data.


As used herein, the terms “camera” and/or “image sensor” may include any device that captures image information, including but not limited to a single lens-based camera, a camera array, a solid-state camera, a mechanical camera, a digital camera, an image sensor, a depth sensor, a remote sensor, a lidar, an infrared sensor, a (monochrome) complementary metal-oxide-semiconductor (CMOS) sensor, an active pixel sensor, and/or other sensors. Individual sensors may be configured to capture information, including but not limited to visual information, video information, audio information, geolocation information, orientation and/or motion information, depth information, distance information, and/or other information. Information captured by one or more sensors may be marked, timestamped, annotated, and/or otherwise processed such that information captured by other sensors can be synchronized, aligned, annotated, and/or otherwise associated therewith. For example, video information captured by an image sensor may be synchronized with information captured by an accelerometer or other sensor. In some implementations, set of sensors 108 may include multiple cameras positioned around the vehicle and synchronized together to provide a 360-degree view of the inside of a vehicle and/or a 360-degree view of the outside of a vehicle. In some implementations, an image sensor may be integrated with electronic storage such that captured information may be (processed and) stored in the integrated embedded storage. In some implementations, a sensor may be configured to transfer captured information to remote electronic storage media, e.g. through “the cloud.”


Server(s) 102 may be configured by machine-readable instructions 106. Machine-readable instructions 106 may include one or more instruction components. The instruction components may include computer program components. The instruction components may include one or more of a parameter determination component 110, a road-specific information component 112, a proximity component 114, a stationary component 116, a detection component 118, a notification component 120, a combinatorial component 122, an environmental component 124, an interface component 126, and/or other instruction components.


Parameter determination component 110 may be configured to determine parameters. For example, the parameters may pertain to the operation of vehicle 12, the current speed of vehicle 12, the current location of vehicle 12, the context of or pertaining to vehicle 12, environmental conditions in or near vehicle 12, and/or other parameters. In some implementations, parameter determination component 110 may be configured to obtain information. The obtained information may include one or more of output signals generated by set of sensors 108, parameters determined based on output signals generated by set of sensors 108, information from external resources 128, and/or other information. For example, in some implementations, parameter determination component 110 may be configured to obtain output signals from set of sensors 108 that convey information pertaining to vehicle 12 and to the operation of vehicle 12, and further configured to determine a current speed of vehicle 12 based on the obtained output signals. In some implementations, parameter determination component 110 may be configured to obtain the current speed of vehicle 12. For example, in some implementations, parameter determination component 110 may be configured to obtain output signals from set of sensors 108 that convey information pertaining to the current location of vehicle 12, and further configured to determine the current location of vehicle 12 based on the obtained output signals. In some implementations, parameter determination component 110 may be configured to obtain the current location of vehicle 12. In some implementations, parameter determination component 110 may be configured to determine and/or obtain the current orientation and/or heading of vehicle 12, either relative to the nearest road, or using an absolute representation such as a real-world coordinate system.


Road-specific information component 112 may be configured to obtain road-specific information. For example, the road-specific information may include information for one or more roads near the current location of vehicle 12 (e.g., as determined and/or obtained by parameter determination component 110). In some implementations, the road-specific information may include one or more of the types of roads near the current location of vehicle 12, the types of geographical location information of the roads near the current location of vehicle 12, and/or other road-specific information. For example, the types of road may include public roads, private roads, and/or other types of roads. In some implementations, the types of roads may include highways, expressways, city streets, residential streets, and/or other types of roads. In some implementations, the types of roads may include 2-lane highways, 4-lane highways, 6-lane highways, 8-lane highways, multi-lane highways, and/or other types of roads. In some implementations, road-specific information may include how many traffic lanes are heading in each direction, how many traffic lanes in total form the entire road in both directions, and/or other specific information regarding one or more traffic lanes of a particular road. For example, in some implementations, the road-specific information may specify the number and width of the individual traffic lanes of a particular road. In some implementations, road-specific information may include local speed limits. In some implementations, road-specific information may be obtained from one or more external databases, e.g., from one or more external resources 128.


In some implementations, geographical location information may specify and/or represent the geographical location of a specific road. For example, the geographical location of a particular road may include GPS information (e.g., a set of GPS coordinates). For example, in some implementations, the road may be assumed to approximate straight lines between adjacent GPS coordinates (e.g., in a set or sequence of GPS coordinates). In some implementations, the geographical information may indicate the (direction-based or geometry-based) centerline of an entire multi-lane multi-directional road. In some implementations, the geographical location of a particular road may include multiple sets of GPS coordinates, using individual sets for individual directions of travel or for individual lanes. In some implementations, the geographical location of a particular road may include two sets of GPS coordinates such that the road may be assumed to exist between boundaries defined by each of the sets. For example, the first set may define the boundary on the outside of the right-most traffic lane heading in a first direction (e.g., North), and the second set may define the boundary on the outside of the right-most traffic lane heading in a second direction (e.g., South), such that this particular road is located between the first and second boundaries. In some implementations, a boundary may define the edge of a traffic lane intended to include vehicular traffic. In some implementations, a boundary may define the edge of the shoulder of road. The particular type of the geographical location information may indicate what the geographical location information represents and/or how it should be interpreted in relation to the geographical location of a particular road. For example, for a first type of 2-lane road, a first type of geographical location information may indicate a particular centerline. For example, for a second type of 2-lane road, a second type of geographical location information may indicate the boundaries of the road (e.g., excluding emergency lanes). For example, for a third type of 2-lane road, a third type of geographical location information may indicate individual (geometry-based) centerlines for each of the lanes. Likewise, many different types of geographical location information may be used to represent the geographical location of a specific 4-lane highway, 6-lane highway, 8-lane highway, and so forth. In some implementations, a particular road may have a different number of traffic lanes heading in opposite directions. In such cases, the direction-based centerline between the traffic lanes heading in opposite directions (e.g., North and South) may not be in the geometric center of the outer boundaries of the entire road.


Proximity component 114 may be configured to make determinations regarding the current location of vehicle 12 in relation to one or more roads near vehicle 12. In some implementations, proximity component 114 may be configured to determine which particular road is closest or proximate to the current location of vehicle 12, and/or what type of road is closest or proximate to the current location of vehicle 12. For example, one determination may be whether vehicle 12 is in a lane of a highway. For example, one determination may be whether any part of vehicle 12 is in a lane of a highway. For example, one determination may be whether vehicle 12 is proximate or adjacent to a lane of a highway. This type of determination may depend of the type of vehicle, the location of one or more GPS sensors on vehicle 12, the heading and/or orientation of vehicle 12 relative to the heading of the nearest traffic lane, and/or other information. For example, one determination may be whether vehicle 12 is within a particular proximity of a highway. For example, the particular proximity may be 25 feet, 50 feet, 75 feet, 100 feet, 150 feet, and/or another distance. For example, one determination may be whether any part of vehicle 12 is within a particular proximity of a highway. In some implementations, one determination may be whether vehicle 12 is within a particular proximity of a road that has a speed limit of at least 40 mph, 45 mph, 50 mph, 55 mph, 60 mph, 65 mph, and/or other ranges of speed limits. In some implementations, the heading and/or orientation of vehicle 12 relative to the heading of the nearest traffic lane may be based on GPS information. In some implementations, the heading and/or orientation of vehicle 12 relative to the heading of the nearest traffic lane may be determined based on processed video information from set of sensors 108.


In some implementations, the particular proximity (as used by proximity component 114) may depend dynamically on one or more of the type of the nearest road, the number and type of traffic lanes, the type of available geographical location information for the nearest road, the local speed limit for the nearest road, and/or other road-specific information. For example, in some implementations, the particular proximity used to determine whether vehicle 12 is within the particular proximity of a highway may be 25 feet for 2-lane roads and 50 feet for 4-lane roads (such that the particular proximity depends dynamically on the number of lanes for the nearest road). In some implementations, certain types of roads, such as on-ramps to highways and off-ramps of highways, may be excluded from consideration for determinations by proximity component 114 (such that a vehicle is not considered within a particular proximity of a highway in case the vehicle is on an on-ramp or off-ramp). For example, in some implementations, the particular proximity used to determine whether vehicle 12 is within the particular proximity of a highway may be 25 feet for roads for which the location of the boundaries are known/available and 50 feet for roads for which only the centerline is known, and the location of the boundaries is not available (such that the particular proximity depends dynamically on the type of available geographical location information for the nearest road). For example, in some implementations, the particular proximity used to determine whether vehicle 12 is within the particular proximity of a highway may be 25 feet for roads for which the location of the shoulder is known/available and 50 feet for roads for which the location of the shoulder is not available (or roads that have no shoulder). In some implementations, the particular proximity may dynamically depend on a combination of multiple factors, such as the number of lanes and the type of available geographical location information, and/or other factors). In some implementations, the particular proximity may dynamically depend on vehicle-specific information. For example, the used particular proximity may be greater for a larger truck and smaller for a small truck or personal vehicle. For example, the used particular proximity may be greater for a truck carrying combustible goods and smaller for a truck carrying non-combustible goods. In some implementations, the particular proximity may dynamically depend on fleet-specific information. For example, the used proximity may be greater for any vehicle in a first fleet of vehicles and smaller for any vehicle in a second fleet of vehicles. For example, a fleet manager and/or other stakeholder may enter and/or select information, via a user interface, that is used to (dynamically) determine the particular proximity.


By way of non-limiting example, FIG. 3 illustrates an exemplary road 300 as may be used by system 100. As depicted, road 300 is a 4-lane highway that includes two lanes in each direction, divided by a dividing strip 305. Lanes 301 and 302 are heading in the same direction. Lanes 303 and 304 are heading in the opposite direction as lanes 301 and 302. Vehicle 12 is partially on a lane 302. System 100 (depicted in FIG. 1) may be configured to determine that vehicle 12 is within a particular proximity (of, say, 25 feet) of road 300, because at least part of vehicle 12 is in lane 302.


By way of non-limiting example, FIG. 4 illustrates an exemplary road 400 as may be used by system 100. As depicted, road 400 is a 6-lane highway that includes three lanes in each direction, divided by a dividing strip 410. Lanes 401, 402, and 403 are heading in the same direction. Lanes 404, 405, and 406 are heading in the opposite direction as lanes 401, 402, and 403. Vehicle 12 is not on any of the lanes. System 100 (depicted in FIG. 1) may be configured to determine that vehicle 12 is within a particular proximity (of, say, 25 feet) of road 400, because at least part of vehicle 12 is within 25 feet of lane 403. In some implementations, system 100 may be configured to determine that vehicle 12 is stationary in an orientation parallel to road 400 (e.g., the differential angle between the orientation of vehicle 12 and lane 403 is less than 30 degrees, which may be considered parallel).


Referring to FIG. 1, stationary component 116 may be configured to determine whether vehicle 12 is or has been stationary. In some implementations, determinations regarding vehicle 12 being stationary may be based on the current speed of vehicle 12 (e.g., the current speed being zero). In some implementations, stationary component 116 may be configured to determine whether vehicle 12 has been stationary continuously for at least a specified duration. In some implementations, the specified duration may be at least 2 minutes, 3 minutes, 5 minutes, 10 minutes, 15 minutes, 20 minutes, and/or another specified duration. In some implementations, the specified duration may vary based on other factors, including but not limited to time of day, weather conditions, visibility conditions, traffic conditions, and/or other factors. In some implementations, a determination whether vehicle 12 is stationary includes a requirement that the engine of vehicle 12 is turned off. In some implementations, no requirement regarding the engine is used to determine whether vehicle 12 is stationary. In some implementations, a determination whether vehicle 12 is stationary includes a requirement that vehicle 12 itself is turned off. In some implementations, no requirement regarding vehicle 12 being turned off is used to determine whether vehicle 12 is stationary. In some implementations, a determination whether vehicle 12 is stationary may include a determination that vehicle 12 is inoperable.


Detection component 118 may be configured to detect vehicle events, including but not limited to vehicle events of vehicle 12. In some implementations, detections by detection component 118 may be based on one or more of the current operation of vehicle 12, information pertaining to vehicle 12, current parameters of vehicle 12 (e.g., as determined by parameter determination component 110), road-specific information, determinations by other components of system 100, and/or other factors, as well as combinations thereof. For example, a particular vehicle event may be detected based on a combination of multiple determinations (e.g., at least two determinations, or at least three determinations, or at least more than three determinations). For example, a particular vehicle event may be detected based on a combination of a first determination that the current location of vehicle 12 is within a particular proximity of the nearest highway, and a second determination that vehicle 12 has been stationary continuously for at least a specified duration. For example, a particular vehicle event may be detected based on a combination of the first determination, the second determination, and a third determination that vehicle 12 is not in a designated area for stopping vehicles. In some implementations, a combination may be used of the first determination, the second determination, and another determination that vehicle 12 is stationary in an orientation that is parallel to the nearest road (e.g., the differential angle between the orientation of vehicle 12 and the nearest road is less than, e.g., 20, 30, and/or 45 degrees, which may be considered parallel). In some implementations, a combination may be used of the first determination, the second determination, and another determination that vehicle 12 was traveling at least a particular speed (e.g., 50 mph), for at least a particular duration (e.g., 5 minutes), in a particular time frame (e.g., a duration of at least 10 minutes immediately preceding the determination that vehicle 12 has become stationary). Other combinations and the use of additional determinations are considered within the scope of this disclosure.


In some implementations, designated areas for stopping vehicles may include different types of geographical areas, including one or more of rest stops, travel centers, truck stops, parking areas, vista points, over-night stay locations, ‘stop-n-park’ locations, ‘park-n-ride’ locations, common stop areas (e.g., these may have been identified and/or designated based on historical usage by other vehicles, crowd-sourcing by drivers, and/or through other information-gathering techniques), fueling stations, combinations of fueling stations and restaurants, other combinations that include one or more fueling stations, and/or other designated areas. In some implementations, a designated area may be indicated and/or defined by a polygon, e.g., using GPS coordinates and/or other real-world coordinates. In some implementations, information regarding designated areas for stopping vehicles may be obtained from external databases.


In some implementations, a determination that a particular vehicle is in a particular designated area for stopping vehicles may be implemented as the entirety of the particular vehicle being completely within the polygon that defines and/or indicates the particular designated area. In some implementations, a determination that a particular vehicle is in a particular designated area for stopping vehicles may be implemented as at least half of the particular vehicle being within the polygon that defines and/or indicates the particular designated area. In some implementations, a determination that a particular vehicle is near a particular designated area for stopping vehicles may be implemented as all or some of the particular vehicle being within a particular proximity of the polygon that defines and/or indicates the particular designated area.


Notification component 120 may be configured to generate notifications, including but not limited to notifications regarding detected vehicle events. In some implementations, notification component 120 may be configured to provide notifications to one or more of a vehicle operator of vehicle 12, remote computing server 129, one or more manual reviewers, one or more fleet managers, one or more supervisors of the vehicle operator of vehicle 12, and/or other stakeholders. In some implementations, notification component 120 may be configured to generate reports that include information regarding detected vehicle events. For example, notification component 120 may be configured to provide a notification to the vehicle operator of vehicle 12 (e.g., through a user interface within vehicle 12, or through a client computing device associated with the vehicle operator) that warns the vehicle operator regarding a detected vehicle event and/or provides a suggestion to move vehicle 12 further from the nearest road.


Combinatorial component 122 may be configured to make combinations of multiple determinations (e.g., 2, 3, 4, or more determinations, either sequentially, simultaneously, and/or arranged in a particular pattern). For example, in some implementations, a combination may include two determinations that occur at substantially the same time, and/or within a short window of time of 1, 2, 3, 4, 5, or more minutes. For example, in some implementations, a combination may include an initial two determinations that occur at substantially the same time, followed by one or more determinations that are made within a particular window of time after the initial two determinations. More elaborate sequences of combinations are considered within the scope of this disclosure. For example, a combination may include a first determination that vehicle 12 was traveling at least, say, 50 mph for at least, say, 5 minutes in a particular time frame. The particular time frame may include a duration of at least, say, 10 minutes immediately preceding the specified duration for a determination that the vehicle has been stationary.


Environmental component 124 may be configured to obtain current environmental conditions, e.g., based on the current location of vehicle 12. In some implementations, environmental conditions may include weather conditions. In some implementations, environmental conditions may include visibility conditions. In some implementations, environmental conditions may include traffic conditions. Combinations of multiple different types of environmental conditions are envisioned within the scope of this disclosure, such as, by way of non-limiting example, weather conditions, visibility conditions, and traffic conditions. In some implementations, environmental conditions may include road-surface conditions such as wet, dry, icy, and/or other conditions for the surface(s) of one or more particular roads. In some implementations, certain determinations in system 100 may be based, at least in part, on obtained environmental conditions. For example, a proximity threshold of 30 feet may be increased to 40 feet responsive to poor visibility conditions.


Interface component 126 may be configured to generate, effectuate, and/or present user interfaces to users, including but not limited to vehicle operators, vehicle owners, fleet managers, and/or other stakeholders. In some implementations, notifications may be provided through one or more user interfaces in one or more vehicles. In some implementations, interface component 126 may be configured to present a particular user interface on a particular client computing platform to a particular user. In some implementations, a user interface may include one or more controllers, joysticks, track pad, a touch screen, a keypad, touch sensitive and/or physical buttons, switches, a keyboard, knobs, levers, a display, speakers, a microphone, an indicator light, a printer, and/or other interface devices. User interfaces may be configured to facilitate interaction between users and system 100, including but not limited to receiving user input from users. In some implementations, received user input may, e.g., be used to select which determinations are to be used for vehicle event detection. In some implementations, received user input may, e.g., be used to select a particular proximity to be used for determinations by proximity component 114 and/or another component of system 100.
