Traffic signal robust control method considering traffic emission uncertainty

Abstract

The invention discloses a traffic signal robust control method considering traffic emission uncertainty. The method comprises the following steps: establishing a mapping relation between a road section traffic flow and road section traffic emission; performing equivalent transformation on the mapping relation by adopting a robust optimization method, and establishing a traffic emission objective function; and establishing a planning model according to the traffic emission objective function in combination with a traffic flow model, and solving an optimal signal timing scheme. According to the method, the mapping relation between traffic emission and traffic flow is established, so that the influence of traffic state change on traffic emission can be directly reflected; and the traffic emission amount is directly taken as an optimization target, so that a more effective traffic signal timing scheme can be found, the traffic emission is reduced, and the atmospheric environment quality is improved.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a traffic signal robust control method considering the uncertainty of traffic emissions. Background technique [0002] The large amount of tail gas emissions generated by urban traffic congestion is the main cause of air pollution. Therefore, in urban traffic management and control, the reduction of tail gas emissions is usually considered as part of the control objectives, so as to optimize the timing of traffic signals at intersections , relieve traffic congestion and reduce pollution emissions, thereby improving traffic performance and improving a series of environmental pollution problems caused by traffic congestion. [0003] Due to the complexity of calculating exhaust emissions, traditional traffic signal control methods usually use some indirect indicators to represent the impact of the control method on traffic exhaust emissions, such as reducing the numbe...
