Method for reducing traffic jam using intelligent traffic information

Abstract

A method in the field of intelligent traffic technique for retarding the congested traffic using the intelligent traffic information is disclosed. The steps as following: (1) setting the traffic situation; (2) selecting the parameter value; (3) obtaining the original state of all vehicles, the vehicle state is defined by the location xn(t), velocity vn(t) and acceleration an(t), n=1,...,N, N is the total population of the vehicles; (4) considering the motion state of vehicle queue at time t>0, assuming the disturbing vehicle moves following the predetermined scheme, the vehicle in queues runs accompanying the queue according to the method based on the intelligent traffic information, considering the velocity and position of all running vehicles at time t>0: xn(t), vn(t) and an(t),n=1,...,N. The invention retards the phenomenon of congested traffic in the course of movement, so it can retard and prevent the appearance of congested traffic when satisfying the developing condition and spreading condition when stimulating the congested traffic.

Description

technical field [0001] The invention relates to a method in the technical field of transportation, in particular to a method for alleviating traffic congestion using intelligent traffic information, which can be widely used in simulated operation of single-lane vehicles, autonomous driving of unmanned vehicles, intelligent transportation systems, traffic areas of control and management. Background technique [0002] With economic growth, the acceleration of urbanization and the sharp increase in the number of cars, urban traffic congestion and congestion are becoming worse and worse. The resulting accidents, noise and environmental pollution have become increasingly serious social problems. Very developed countries cannot avoid increasingly acute traffic problems. However, in real life, only relying on the continuous expansion of the traffic road network not only consumes a lot of manpower and material resources, but also cannot fundamentally solve the traffic problem becau...

Problems solved by technology

However, in all the above-mentioned research works, only the occurrence and causes of traffic congestion in actual traffic activities have been expressed, and no methods to slow down and prevent traffic congestion that need to be solved urgently have been proposed.
