Research on Reversible Lane Optimization Based on hierarchical Programming Model

The setting of variable lane is a very complex hybrid system, and few of them can consider it from the perspective of the whole urban network. In this paper, from the city of morning and evening rush hour traffic distribution is not balanced, and consider the reduction of the capacity of multiple lanes, through BPR function as basic function, a kind of hierarchical programming model is established. Using independent establishment of testing road network simulation of the traffic network, through the data before and after the simulation of variable lane setting system, comparing the total travel time variable lane after setting the system total travel time. it is verified that the effectiveness of the hierarchical programming model is also verified.
