Traffic sign information indication system and method

Abstract

The invention discloses a traffic sign information indication system and method. A lane indication board is arranged at one side of the road, and the lane indication board is provided with an LED indication assembly at each piece of lane information; a traffic indication service platform comprises an acquisition unit, a vehicle position analysis unit and an instruction issuing unit; the acquisition unit is used for acquiring position information of vehicles in a municipal administration area; the vehicle position analysis unit is used for calling an electronic map of a municipal administrationarea, mapping the obtained position information of the vehicles into the electronic map in real time, defining an area between each intersection stop line and the lane indicator in the electronic mapas a detection area and identifying and detecting the number of the vehicles in each lane in the detection area; the instruction issuing unit is used for issuing a corresponding first indication instruction to the LED indication assembly according to the number of vehicles in each lane in the detection area so as to control the LED indication assembly of the corresponding lane to give an indication. The system and the method have the characteristic of relieving urban traffic pressure.

Description

technical field [0001] The invention relates to the field of traffic control systems, in particular to a traffic sign information indicating system and method. Background technique [0002] On urban roads, each lane is divided, and vehicles travel in their own lanes to ensure the safety and smoothness of vehicle driving. [0003] At the intersection of urban roads, some vehicles need to enter the turning lane if they need to turn, and some vehicles need to enter the straight lane in advance if they need to go straight. Lane signs are set at the front preset position to indicate in advance to ensure that vehicles can enter their respective lanes in advance. [0004] Among them, the urban traffic problem is a common problem in large and medium-sized cities. How to improve the traffic capacity of existing urban roads during peak hours and alleviate traffic congestion is an important issue before us. [0005] When a vehicle encounters a traffic light while driving on an urban ...

Problems solved by technology

However, when the traffic pressure on urban roads increases, the number of vehicles appearing on urban roads increases, so when waiting for a red light, the driver cannot distinguish the number of vehicles on each lane in advance, and thus cannot change lanes in advance to enter a place with a small number of vehicles. On the lane, so that a large number of vehicles are congested in the same lane and wait for the red light, so that when the red light ends, the vehicles congested in the same lane cannot pass through the traffic light intersection within the green light time, resulting in vehicle congestion in the original lanes, increasing the pressure of urban traffic
