Abstract

Urban traffic is a complex system composed of multiple roads and intersections. The unimpeded road traffic directly affects the development of urban economy. The intersection is the pivot of urban road traffic and plays an important role in the management of the road traffic. Traffic at an intersection often is influenced by other intersections and is a result of a joint impact of them, there must be the relationship between an intersection and several other intersections. This relationship is difficult to express with determined mathematical formula due to the stochasticity of resident travel. However, the copula function can connect the distribution function of traffic flow at an intersection with the joint distribution function of traffic flow at several upstream intersections to establish a mathematical model and predict the traffic flow at this intersection. This traffic flow can be regarded as a traffic control parameter for the intersection, and can effectively improve the coordinated control in the region.This method has achieved good results with experimental validation.
