Problems solved by technology

[0004] Since there are 3-10 different lanes in the same direction at the intersection, and the driving direction of each lane is different: straight lane, U-turn lane, left-turn lane, right-turn lane, uncontrolled lane, etc. ; There are certain difficulties in the exclusive transmission of wireless signals, so the invention patent of the above-mentioned publication number CN02136102.9 has technical obstacles in practicality, and the technical solution indicated in the specification cannot be realized

Embodiment 1

[0021] On each lane before the intersection on the road, there are several wireless signal devices for lane-related dynamic information buried in the lane 1-20 meters away from the intersection. The signals of the wireless signal devices on the parallel lanes in the same direction do not interfere with each other. Only the vehicles driving in this lane can receive the driving direction and traffic light signals of this lane, and will not receive the dynamic signals of the lanes on both sides. The lane signal includes the driving direction of the lane at the intersection, and the signal information of the traffic lights at the intersection to control the lane (the time for passing and the waiting time for the next time to pass).

Embodiment 2

[0023] Due to the increasing congestion of urban traffic, it is especially necessary to know the driving direction of the lane at the front intersection when driving encounters a queue of vehicles (it is difficult to change lanes when the lane is crowded and vehicle collisions are prone to occur). On roads that are often congested, a wireless signal device for lane information is buried on the lane 20-80 meters away from the front intersection. The vehicle can only receive the driving party in this lane, and will not receive the signals from the lanes on both sides.

Abstract

The invention discloses a vehicle road information display system, which comprises a wireless signal sending device and a wireless signal receiving device. The invention is characterized in that the wireless signal sending device and the receiving device are respectively arranged on a traffic lane of a road and an automobile, the sending direction of the wireless signal sending device is only limited to the automobile of the current traffic lane and the traffic lane, and automobiles on traffic lanes at both sides and the traffic lanes can not receive the signals of the wireless signal sending device.

Description

technical field [0001] The invention belongs to the technical field of traffic information display, in particular to a vehicle road information display system. Background technique [0002] At present, the number of vehicles in the country is increasing year by year, and the team of drivers is also increasing day by day. The development of urban roads is far behind the number of motor vehicles. Therefore, lane allocation changes at road intersections often occur. Sometimes when drivers are waiting for traffic lights on the road (sometimes the traffic jam is very long, and the ground marks cannot be seen), they will ask "Is this road going straight? Turn left? Or turn right? "Confusion, often occurs in violation of discipline at crossings changing lanes. There is currently no corresponding display device. [0003] Chinese Patent Publication No. CN02136102.9 entitled "Auto Adaptive System for Traffic Signal Lights" discloses an adaptive system for traffic signal lights. To ...
