Road crossing signal dynamic regulation method, device and system

Abstract

The present invention provides a road crossing signal dynamic regulation method based on online traffic simulation. The method comprises: calculating the current traffic operation parameters in the current signal timing scheme according to the current traffic flow data; performing signal optimization timing calculation according to the current signal timing scheme and the traffic data, and obtaining an optimized signal timing scheme; performing traffic simulation aiming at the optimal signal timing scheme, and obtaining simulated and outputted traffic operation parameters; and finally, comparing the simulated traffic operation parameters with the current traffic operation parameters, if the simulated traffic operation parameters exceed a presetting threshold, outputting the optimal signal timing scheme, and performing road crossing signal timing through adoption of the optimal signal timing scheme. The road crossing signal dynamic regulation method, device and system are able to provide different signal timing schemes for signal lights at the crossing aiming at road traffic flow at different time periods so as to improve the passing efficiency of a crossing and ensure that the crossing is able to operate in the optimal mode all the time in the condition that the road crossing operates at the optimal timing scheme.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a method and system for dynamic adjustment of intersection signals based on online traffic simulation. Background technique [0002] In recent years, my country's social economy has continued to develop rapidly, and the transportation industry has also maintained a relatively rapid growth. Transportation has become an indispensable part of people's work and life, and plays an important role in ensuring the normal operation of society. Since the last century, my country has gradually improved its transportation network nationwide, but the growth rate of motor vehicles is still much higher than that of roads and other transportation facilities. Large and medium-sized cities have thus produced a series of traffic problems, such as traffic jams, traffic exhaust pollution, traffic safety accidents, etc., resulting in certain casualties and economic losses. Facts have proved that relyi...
