Abstract

The invention discloses an urban traffic signal optimization method and an urban traffic signal optimization system. The method comprises the following steps of judging whether a current urban fragmented region is reasonable or not according to the signal period duration, the spatial position and the traffic flow of an intersection on a trunk; judging whether an urban fragmented region control strategy is reasonable or not when the current urban fragmented region is judged to be reasonable; if the urban fragmented region control strategy is judged to be reasonable, determining whether an optimized space exists in the coordination of road sections or not; if no optimized space exists in the coordination of road sections, judging whether the intersection needs to be optimized or not; if theintersection needs to be optimized, carrying out the signal control, the traffic organization and the traffic order optimization on the intersection. In this way, the traffic signal optimization is carried out on the whole city level. The traffic jam can be relieved. Meanwhile, the signal optimization can be performed specifically. The optimization efficiency of the optimal technical personnel isimproved, and the ordered development of signal optimization work is guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the field of traffic signal control, in particular to a method and system for optimizing city-level traffic signals. Background technique [0002] With the rapid development of the economy, the level of urbanization continues to increase, and the number of vehicles on urban roads continues to increase, frequent congestion has become very common. One-third of the city's peak commuting in the country is threatened by congestion, and traffic congestion has increased from one to one. The trend of second-tier cities spreading to third- and fourth-tier cities. Signal control is an important technical means to alleviate urban traffic congestion, but most urban signal control systems or equipment have not been effectively used. Signal optimization is mainly based on traffic jams and key intersections. Urban-level traffic signal optimization methods and theories are not immature. Contents of the invention ...
