1. Technical Field
The disclosure generally relates to a road traffic control system.
2. Description of the Related Art
With the rapid development of urbanization, traffic problems have become increasingly serious. For example, when a car drives behind a truck approaching an intersection, the driver in the car may not see the traffic lights at the intersection because the truck is blocking the traffic lights from line of sight, which may cause a traffic accident if the driver of the car is not careful.
Therefore, there is room for improvement within the art.
Many aspects of a road traffic control system can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the road traffic control system. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.

The bracket 30 includes a support frame 32 and a beam 34. The support frame 32 is vertically installed at the edge of one side of another lane which includes a plurality of stop lines on the surface of the lane. The beam 34 is vertically fixed at the top end of the support frame 32 and is substantially aligned with a first stop line 33 on the lane in parallel. The indicators 40 can be light emitting diodes (LEDs) and are installed at the beam 34 above the first stop line 33. The light controller 50 controls the indicators 40 to emit red, yellow or green light perpendicular towards the lane, forming a light beam 35.
The light controller 50 can be installed on the light support 10 or the bracket 30. In this embodiment, the light controller 50 is positioned on the light support 10 and is electrically connected to the traffic lights 20 and the indicators 40. The light controller 50 controls the turning on or off the traffic lights 20 and the indicators 40 synchronously. For example, when the light controller 50 controls the traffic lights 20 to emit red light, the light controller 50 then controls the indicators 40 to emit red light at the same time.
In this embodiment, the light controller 50 can control the indicators 40 to emit red, yellow or green light by adjusting and controlling the current flowing through the indicators 40. For example, when the current flowing through the indicators 40 is about 10 mA, the indicators then 40 emit red light; when the current of the indicators 40 is about 15 mA, the light controller 50 then controls the indicators 40 to emit yellow light; when the current flowing through the indicators 40 is about 20 mA, the light controller 50 then controls the indicators 40 to emit green light.
The alarms 60 are positioned on the guardrails 200 and electrically connected to the light controller 50. When the traffic lights 20 are changed to yellow or red color, the light controller 50 sends a command signal to the alarms 60 to activate and enable the alarms 60 to output warning signals. In this embodiment, the number of the alarms 60 is two, one alarm 60 is about 10 meters away from the first stop line 33, and the other alarm 60 is about 20 meters away from the first stop line 33.
When a car drives to the intersection and the driver of the car cannot see the traffic lights 20 due to the line of sight being blocked by other vehicles. If the traffic lights 20 emit red light, the light controller 50 controls the indicators 40 to emit red light to form a red light beam to remind the driver of car to promptly slow down or stop. On the other hand, when the traffic lights 20 are changed to red light, the light controller 50 sends a command signal to the alarms 60 to enable and activate the alarms 60 to output warning signals to alert the driver to slow down or stop in time.
In summary, in the road traffic control system 100 of the disclosure, the plurality of indicators 40 are installed above the stop lines of the lane, and the light controller 50 synchronously controls to turn on or off the indicators 40 and the traffic lights 20. Thus, even through the traffic lights 20 are blocked from line of sight, the indicators 40 can still provide the same color lights as the traffic lights 20 for the drivers. Furthermore, the light controller 50 can control the alarms 60 to output warning signals to alert the driver of the car to slow down or stop in time to avoid traffic violations or accidents.
In the present specification and claims, the word “a” or “an” preceding an element does not exclude the presence of a plurality of such elements. Further, the word “comprising” does not exclude the presence of elements or steps other than those listed.
It is to be understood, however, that even though numerous characteristics and advantages of the exemplary disclosure have been set forth in the foregoing description, together with details of the structure and function of the exemplary disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of this exemplary disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
