Abstract

The invention discloses a method for avoiding traffic jam in a central area of a metropolis, and the method is characterized in that the method comprises the following steps: 1), building a one-way traffic highway: selecting two separated and parallel bidirectional traffic main roads passing through the center of a city, and enabling the two main roads to be changed into two one-way traffic highways with the opposite driving directions; 2), controlling vehicles on the one-way traffic highways, so as to enable the vehicles to approach to the specified highest driving speed of the highways; 3), carrying out the control of traffic lights at each intersection of the one-way traffic highways; 4), controlling the traffic lights according to the calculated signal period C0 of each intersection and the lighting time of the green light of each intersection, and enabling the traffic light to be green when the vehicle arrives at the intersection. The method builds the one-way traffic highways, controls the speed of the vehicles and the lighting time of the green lights of the traffic highways, enables the green lights to be turned on when the vehicles reach the intersections, and can effectively avoid the traffic jam of the main roads at the center of the city.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method for preventing traffic congestion in the central area of ​​a metropolis.
