Intelligent transportation anti-congestion system and device

Abstract

The invention discloses an intelligent transportation anti-congestion method. The method comprises the steps that a vehicle-mounted terminal detects the speed of a vehicle and determines the position of the vehicle; a server side receives speed and position data sent by the vehicle-mounted terminal; the server side calculates road congestion indexes according to the speed and position data; the vehicle-mounted terminal receives the data of the server side and displays road congestion conditions; and the navigation of the vehicle-mounted terminal plans to avoid congestion sections according to the road congestion conditions. The invention further discloses an intelligent transportation anti-congestion device. The device comprises the vehicle-mounted terminal, the server side and a traffic light controller. The server side comprises a server. The server is connected with a first network communication module, a second network communication module, a road congestion index calculation module and a statistical analysis module and performs data interaction and control. According to the intelligent transportation anti-congestion system and device, the characteristic of accurate positioning of the vehicle-mounted terminal is adopted, road selection is facilitated for users, and meanwhile, working conditions of traffic lights can be adjusted intelligently.

Description

technical field [0001] The invention relates to the technical field of traffic management systems, in particular to an intelligent traffic congestion prevention system and device. Background technique [0002] At present, traffic lights at urban intersections generally have a fixed traffic light conversion cycle based on the number of vehicles at the intersection. However, the fixed cycle will cause vehicles in some directions to pass through long ago, while vehicles in other directions will queue up for the green light, resulting in a greatly reduced traffic rate. In cities In traffic, traffic light signal is the most important element to manage the traffic network. In recent years, the traffic volume of urban traffic has increased significantly, which has brought great pressure to traffic. Improving the traffic rate at intersections has very important practical significance for alleviating traffic jams. [0003] It turns out that the driver can only know the road conditio...

AI Technical Summary

Problems solved by technology

[0003] It turns out that the driver can only know the road conditions through the radio and the telephone service desk, which is very inconvenient. Sometimes he only knows that the road is blocked when he arrives at a congested section, and regrets not taking another road. It takes an hour or two or even longer to unblock, and the efficiency is very low

[0004] Therefore, with the existing road congestion prevention systems and devices, the driver cannot choose the driving route according to the road conditions, let alone effectively understand the traffic congestion situation, and the system cannot intelligently intervene in the road traffic conditions according to the road condition information to adjust and control the vehicle's route. Solve the current problem of urban road congestion
