Traffic light and information interaction system between traffic light and driver

Abstract

The invention discloses a traffic light and an information interaction system between the traffic light and a driver, and can enable the driver to grasp master state and time information of the traffic light in front in advance and properly adjust vehicle speed in an allowable range, thereby improving the probability of meeting a ''green light''. The technical scheme is that GPS information of the traffic light in front is obtained through wireless communication, combined with the current GPS information of the vehicle, distance between a current position of the vehicle and the traffic light is calculated according to a formula AB=R*arccos[(sinb1)*(sinb2)+(cosb1)*(cosb2)*cos(a1-a2)], and combined with working parameters, a current light color and countdown remaining time of the traffic light, a vehicle speed range for the vehicle to smoothly pass is calculated according to v=s / t. The information interaction system provided by the invention is novel in method, and can effectively reduce start and stop times of the vehicle at crossroads, thereby reducing energy consumption, reducing waiting time, and improving passing efficiency, and the information interaction system belongs to innovation in the field of intelligent transportation.

Description

technical field [0001] The invention relates to an information interaction system, in particular to an information interaction system between a traffic light and the driver. Background technique [0002] Since the advent of traffic lights, it has played a vital role in maintaining traffic order at intersections. The information interaction between existing traffic lights and drivers can only start after the traffic lights enter the driver's field of vision. The rules are "red light" to stop, "yellow light" to wait, and "green light" to drive. The probability of the traffic light is certain. On the premise of not changing the traffic rules, if the driver can grasp the status and time of the traffic light ahead, he can properly adjust the speed within the allowable range, so that when he encounters a "green light" The probability is improved, which is of great significance. However, there is no information interaction system between traffic lights and drivers at present, and ...

The information interaction between existing traffic lights and drivers can only start after the traffic lights enter the driver's field of vision. The rules are "red light" to stop, "yellow light" to wait, and "green light" to drive. The probability of the traffic light is certain. On the premise of not changing the traffic rules, if the driver can grasp the status and time of the traffic light ahead, he can properly adjust the speed within the allowable range, so that when he encounters a "green light" The probability is improved, which is of great significance, but there is no information interaction system between traffic lights and drivers, and the existing technology has not yet solved this problem
