The present technology relates to traffic control devices, more particularly, to automated traffic control devices.
This section provides background information related to the present disclosure which is not necessarily prior art.
Traffic control devices can include markers, signs, and signal devices used to inform, guide, and control traffic, including pedestrians, motor vehicle drivers and bicyclists. These devices are usually placed adjacent, over or along the highways, roads, traffic facilities, and other public areas that require traffic control. Such traffic control devices can range from passive signage to active lamps and signals.
Traffic control devices can protect workers in various settings, including work event settings on roadways, bridges, tunnels, utilities, and other infrastructure from various hazards outside and inside of the work event zone. Hazards can include damages or injuries resulting from excessive speeding, being struck by an object, moving equipment, and or accidents from distracted drivers. However, traditional traffic control devices can have shortcomings related to the following:
SAFETY FOR WORKERS: In event zones, especially on two lane roads, workers are often used to help control the flow of traffic. These workers stand on the road, exposed to traffic, with signs and communication devices working together to stop and control one or more lanes of traffic. In today's world of distracted driving, these workers are at increased risk of being struck by an oncoming vehicle.
COMMUNICATION: Part of the requirement of work event zones is that signage must be displayed at a specified distance before the start of the event zone and communicate the hazard quickly. Undesirably, traditional traffic control devices can be limited in displaying one particular type of message (e.g., a stop sign can only be used to stop traffic).
EMERGENCY RESPONSE TIME: There are always going to be accidents on the highways which require getting emergency response vehicles to the scene, and setting up external traffic control which requires time, equipment, and people. Reducing response times can save lives.
FIXED EVENT ZONES: Traditional event zones are fixed and do not move as the work progress along the road, where workers are hence required to physically move the traffic control devices as the event zone progresses. Since setting up event zones can be labor intensive, some construction companies will section off large areas of the road that might be worked on during the course of a day, week, or even longer. These event zones are longer than required and negatively impact traffic more than what is necessary.
ENVIRONMENTAL IMPACT: Traditional event zones can require trucks to assist in setting up and tearing down event zones. Trucks are driven by workers to the sign locations, stopped while idling, so the sign can be put up or taken down, moved to the next area, and repeated.
ERGONOMICS: Traditional event zones typically require workers to be outside for prolong periods, standing on hard pavement in the blistering heat or shivering in cold. The ergonomics of lifting and moving traffic control devices also poses an ergonomic risk to road workers.
LABOR: It can be very difficult to hire and retain people, especially for very physical and demanding jobs that can include uncomfortable working conditions.
COST: The rising cost of road maintenance impacts everyone, as taxpayers ultimately pay for road maintenance. It is very costly to maintain and construct roads.
These inefficiencies have challenged engineers and planners to design traffic control devices that permit an optimal flow of vehicles, while militating against the aforementioned issues.
There is a continuing need for a traffic controlling system and method that can automatically position a traffic controller. Desirably, such a traffic controlling system and method can be modular to implement multiple traffic control options.
In concordance with the instant disclosure, a traffic controlling system and method that can automatically position a traffic controller, and which can be modular, has been surprisingly discovered.
In certain embodiments, traffic controlling systems are provided that can include a platform, a sensor, and a control unit. The platform can have a top side, a locomotion system, and a receiving area. The locomotion system can be configured to move the platform into a preselected position. The receiving area can be disposed on the top side and configured to receive a traffic indicator module. The sensor can be configured to generate location data of the platform. The control unit can be in communication with the sensor and the locomotion system. The control unit can be configured to receive the location data. The control unit can also be configured to determine if the platform is in the preselected position. The control unit can be further configured to execute instructions including the pathway that the platform needs to travel to be positioned in the preselected position.
In certain embodiments, traffic controlling systems are provided that can include another platform configured in a similar fashion to the platform. The locomotion system of the another platform can be configured to move the another platform into a preselected warning distance. The warning distance can be defined as a gap between the another platform and the platform. The sensor can be configured to generate location data of one of the platform and the another platform. The instructions can also include a warning pathway that the another platform needs to travel to be positioned in the preselected warning distance.
In certain embodiments, ways of using such traffic controlling systems are provided. The sensor can generate location data of the platform. The sensor can send the location data to the control unit. The control unit can receive the location data. The control unit can determine if the platform is in the preselected position by comparing the preselected position with the location data. The control unit can execute the instructions including the pathway that the platform needs to travel to be positioned in the preselected position.
It is also possible that one or more platforms can be configured to be automatically deployed to a set location. One or more platforms can also be configured to be automatically positioned in a preselected location until called back if the event zone is fixed. If the event zone is a moving event zone, the platform(s) can be configured to be positioned at a preselected distance away from the moving event zone based on references points disposed in the event zone. The reference points can include trucks, equipment, workers, flags, markers, GPS locations, etc. Or it could be programmed to run specific operations, paths, or move things from point to point.
The platform can have a plurality of traffic indicator modules which can relate to traffic communication tools that can include road signs, flags, flashing lights, LED monitors, traffic lights, stop signs, etc. These can permit the platform to convey the required event zone notification to traffic via signs, signals, lights, flashing arrows, message boards, and or other communications means. The platform can control traffic of roads by replacing the workers with mounted communication devices and connected stoplights with the capability of communicating to a host vehicle and or additional traffic platforms.
The platform can be used with a fixed event zone or a movable event zone. Traditionally, event zones are fixed and are set up for the work schedules for the entire day. Also, the advanced notification signs were fixed. Undesirably, the workers were exposed to danger. By using the platform, signage and stop lights can be mounted to a moving device, set to hold a fixed position and or stay at the preselected distance away from reference points within the event zone. This can allow the event zone to be smaller and still be safe by moving the signage with the event zone, thus shortening and improving the flow of traffic.
The platform can be designed to create flexible, safe event zones and be automatically retrieved and/or picked up to return to the maintenance garage safely. By utilizing the platform in conjunction with other technology, workers can be reduced or completely removed from the road, which can dramatically improve worker safety and cost savings.
The plurality of modules can also include sensors that gather data. Non-limiting examples of the data can include traffic patterns, traffic density, road quality, weather conditions, etc. Other modules could perform various functions of road maintenance, such as air blow off, vacuuming, and other tasks.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
The following description of technology is merely exemplary in nature of the subject matter, manufacture and use of one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application or in such other applications as may be filed claiming priority to this application, or patents issuing therefrom. Regarding methods disclosed, the order of the steps presented is exemplary in nature, and thus, the order of the steps can be different in various embodiments, including where certain steps can be simultaneously performed, unless expressly stated otherwise. “A” and “an” as used herein indicate “at least one” of the item is present; a plurality of such items may be present, when possible. Except where otherwise expressly indicated, all numerical quantities in this description are to be understood as modified by the word “about” and all geometric and spatial descriptors are to be understood as modified by the word “substantially” in describing the broadest scope of the technology. “About” when applied to numerical values indicates that the calculation or the measurement allows some slight imprecision in the value (with some approach to exactness in the value; approximately or reasonably close to the value; nearly). If, for some reason, the imprecision provided by “about” and/or “substantially” is not otherwise understood in the art with this ordinary meaning, then “about” and/or “substantially” as used herein indicates at least variations that may arise from ordinary methods of measuring or using such parameters.
All documents, including patents, patent applications, and scientific literature cited in this detailed description are incorporated herein by reference, unless otherwise expressly indicated. Where any conflict or ambiguity may exist between a document incorporated by reference and this detailed description, the present detailed description controls.
Although the open-ended term “comprising,” as a synonym of non-restrictive terms such as including, containing, or having, is used herein to describe and claim embodiments of the present technology, embodiments may alternatively be described using more limiting terms such as “consisting of” or “consisting essentially of.” Thus, for any given embodiment reciting materials, components, or process steps, the present technology also specifically includes embodiments consisting of, or consisting essentially of, such materials, components, or process steps excluding additional materials, components or processes (for consisting of) and excluding additional materials, components or processes affecting the significant properties of the embodiment (for consisting essentially of), even though such additional materials, components or processes are not explicitly recited in this application. For example, recitation of a composition or process reciting elements A, B and C specifically envisions embodiments consisting of, and consisting essentially of, A, B and C, excluding an element D that may be recited in the art, even though element D is not explicitly described as being excluded herein.
As referred to herein, all compositional percentages are by weight of the total composition, unless otherwise specified. Disclosures of ranges are, unless specified otherwise, inclusive of endpoints and include all distinct values and further divided ranges within the entire range. Thus, for example, a range of “from A to B” or “from about A to about B” is inclusive of A and of B. Disclosure of values and ranges of values for specific parameters (such as amounts, weight percentages, etc.) are not exclusive of other values and ranges of values useful herein. It is envisioned that two or more specific exemplified values for a given parameter may define endpoints for a range of values that may be claimed for the parameter. For example, if Parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that Parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if Parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, 3-9, and so on.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

While still referring to
The navigation unit 164 can be configured to generate the location data. A non-limiting example of the navigation unit 164 can include a satellite-based radionavigation system, such as the Global Positioning System (GPS). Desirably, this can permit the location of at least one of the platform 102 and/or the another platform 103 to be determined with sufficient accuracy. It should be appreciated that one skilled in the art can select different navigation systems for the navigation unit 164, as desired.
Other non-limiting examples of the sensor 104 can include temperature sensors, azimuth sensors, elevation sensors, gyroscopes, barometers, compasses, sonar technology, lidar technology, radar technology, etc. However, it should be appreciated that other types of sensor technologies are contemplated for the sensor 104 or a combination thereof within the scope of this disclosure.
The event zone 124 can have at least one reference point 166, as shown in
In certain examples, the sensor 104 can be configured to detect the reference point 166 of the event zone 124. Desirably, this can allow the traffic controlling system 100 to determine the approximate location of the event zone 124 with respect to the sensor 104. In addition, the traffic controlling system 100 can use this information to position the platform 102 and/or the another platform 103 at a predetermined distance 168 from the reference point 166. The predetermined distance 168 can be defined as the distance between the platform 102 and/or the another platform 103 with the reference point 166.
Advantageously, this can permit the platform 102 and/or the another platform 103 to be more precisely positioned at a predetermined distance 168 from the reference point 166. It should be appreciated that a person skilled in the art can select different objects to be used as the reference point 166. In addition, it should also be appreciated that the number of reference point 166 can be scaled by a skilled artisan, as desired.
With reference to
The control unit 106 can have a processor and memory. The memory can include a tangible, non-transitory computer readable medium with processor-executable instructions stored thereon. Non-limiting examples of the control unit 106 can be a server, a cloud server, a programmable logic controller (PLC), a computer, and a human-machine interface (HMI). Different types of technology can be employed for the control unit 106, within the scope of this disclosure. In some examples, the control unit 106 can be remotely disposed from the platform 102 and/or the another platform 103. In other instances, the control unit 106 can be disposed on at least one of the platform 102 and the another platform 103. It should be appreciated that a skilled artisan can scale the number of the control unit 106, as desired.
The control unit 106 can be configured to receive at least one of the traffic-related information and the location data. In some instances, the control unit 106 can be continuously receiving the location data and the traffic-related information from the sensor 104. In other instances, the control unit 106 can receive the location data and the traffic-related information from the sensor 104 at a predetermined interval. The predetermined interval can be scaled according to how often the platform 102 and/or the another platform 103 needs to be positioned and repositioned.
The control unit 106 can also be configured to determine if the platform 102 and/or the another platform 103 is in the preselected position 122. This can be accomplished by comparing the location data with the preselected position 122. Specifically, the control unit 106 can compare the location data of the platform 102 and/or the another platform 103 with the preselected position 122. If the approximated location of the platform 102 and/or the another platform 103 is different than the preselected position 122, then the control unit 106 can determine the platform 102 and/or the another platform 103 is not in the preselected position 122. As will be discussed in the further detail below, the control unit 106 can be configured to automatically control and adjust the positioning of the platform 102 and/or the another platform 103. In addition, the control unit 106 can configured to receive instructions from the user.
In addition, the control unit 106 can be configured to determine if the platform 102 and/or the another platform 103 is at the predetermined distance 168 by comparing the location data and the time and location when the sensor 104 detected the reference point 166. For example, the control unit 106 can compare the location data of the platform 102 and/or the another platform 103 with the predetermined distance 168. If the approximated location of the platform 102 and/or the another platform 103 is different than the predetermined distance 168, then the control unit 106 can determine the platform 102 and/or the another platform 103 is not in the predetermined distance 168. The predetermined distance 168 can also be used to determine if the platform 102 and/or the another platform 103 is in the preselected position 122 by comparing the predetermined distance 168 with the location of the event zone 124. For example, if the event zone 124 is five (5) feet from the preselected position 122 and the platform 102 is at the predetermined distance 168, which is six (6) feet from the preselected position 122, then the control unit 106 can determine where the platform 102 is with respect to the preselected position 122. In this way, the platform 102 and the another platform 103 can move in response to movement of the reference point. For example, where the reference point includes a road maintenance vehicle or road maintenance equipment, the vehicle or equipment may move as work is completed, where the platform 102 and the another platform 103 can move in response thereto. A moving work event zone can therefore be followed by the platform 102 and the another platform 103.
The control unit 106 can be further configured to execute instructions to position and reposition the platform 102 and/or the another platform 103. The instructions can include a pathway that the platform 102 and/or the another platform 103 needs to travel to be positioned in the preselected position 122. The pathway can include a distance and direction between the platform 102 and/or the another platform 103 with the preselected position 122. Desirably, the pathway can permit the platform 102 and/or the another platform 103 to be positioned or repositioned in the preselected position 122, without having to manually move the platform 102 and/or the another platform 103. It should be appreciated that a skilled artisan can select different variables and information to be included with the pathway, within the scope of this disclosure.
The instructions can further include a warning pathway that the platform 102 and/or the another platform 103 needs to travel to be positioned in the preselected warning distance 158. The warning pathway can include a distance and direction between the platform 102 and/or the another platform 103 with the preselected warning distance 158. Desirably, the warning pathway can permit the platform 102 and/or the another platform 103 to be positioned or repositioned in the preselected warning distance 158, without having to manually move the platform 102 and/or the another platform 103 to the preselected warning distance 158. It should be appreciated that a skilled artisan can select different variables and information to be included with the warning pathway, within the scope of this disclosure.
In certain examples, the control unit 106 can be configured to generate the instructions. For example, the control unit 106 can be configured to generate the pathway by comparing the approximate position of the platform 102 and/or the another platform 103 with the preselected position 122, and then determine the distance and direction between the platform 102 and/or the another platform 103 with the preselected position 122. The pathway can also be generated by comparing the predetermined distance 168 with the location of the event zone 124. It should be appreciated that a skilled artisan can employ different methods for generating the pathway, within the scope of this disclosure.
In addition, the control unit 106 can be configured to generate the predetermined distance 168 by comparing the approximate position of the platform 102 and/or the another platform 103 with the reference point 166, and then determine the distance and direction between the platform 102 and/or the another platform 103 with the preselected distance. It should be appreciated that a person skilled in the art can select different methods for generating the predetermined distance 168, within the scope of this disclosure.
The control unit 106 can also be configured to generate the warning pathway by comparing the approximate position of the platform 102 and/or the another platform 103 with the preselected warning distance 158, and then determining the distance and the direction between the platform 102 and/or the another platform 103 with the preselected warning distance 158. It should be appreciated that one skilled in the art can select different methods for generating the warning pathway, as desired.
Now referring to
The instructions can also include at least one update to one of the pathway, the predetermined distance 168, and the warning pathway that the platform 102 and/or the another platform 103. Desirably, updating the pathway, the predetermined distance 168, and the warning pathway can permit the traffic controlling system 100 to maintain the platform 102 and/or the another platform 103 in the desired position, even when the preselected position 122 and/or the preselected warning distance 158 changes. For example, the preselected position 122 can change as the moving event zone 124 moves along a road. Advantageously, this permits the traffic controlling system 100 to control the flow of traffic around the moving event zone 124 as it moves, unlike conventional traffic controlling methods that can require entire roads to be shut down to compensate for when the event zone 124 needs to be moved. One of the pathway, the predetermined distance 168, and the warning pathway can be updated every update set interval. In certain instances, the update set interval substantially continuously. In other instances, the update set interval is every couple of minutes. A skilled artisan can scale the update set interval, when appropriate (e.g., a lower set interval for situations where the platform 102 needs to be repositioned faster). In addition, in certain examples, the user can update and provide pathway, the predetermined distance 168, and the warning pathway to the control unit 106 as well. It should be further appreciated that a skilled artisan can select other methods for updating the pathway, the predetermined distance 168, and the warning pathway, within the scope of this disclosure.
The control unit 106 can be configured to automatically engage the locomotion system 110 to position the platform 102 and/or the another platform 103 using the instructions. For example, the control unit 106 can act as an autopilot and directly operate the locomotion system 110 to position the platform 102 and/or the another platform 103 into the preselected position 122 using the instructions. Advantageously, the control unit 106 can be used to automatically adjust the platform 102 and/or the another platform 103 as the moving event zone 124 moves along that road, which can facilitate seamless transitions as the work gets completed. In certain examples, the user directs the control unit 106 to engage the locomotion system 110 to position. For example, the user can use the GUI of the software platform 172 to direct the control unit 106 to engage the locomotion system 110 for positioning the platform 102 and/or the another platform 103. Desirably, this can allow the user to have precise control over movements the platform 102 and/or the another platform 103.
It should be appreciated that the sensor 104 and the control unit 106 can be combined with one or more modules to accomplish the same or similar functions, within the scope of this disclosure.
With reference to
Now referring to
Advantageously, the traffic controlling system 100 and method can automatically position and reposition the platform 102 and/or the another platform 103. In addition, the platform 102 and/or the another platform 103 can each receive the traffic indicator module 134. Desirably, this can permit the platform 102 and/or the another platform 103 to be customized for a given task.
While certain representative embodiments and details have been shown for purposes of illustrating the invention, it will be apparent to those skilled in the art that various changes can be made without departing from the scope of the disclosure, which is further described in the following appended claims.
