Study on City Road Network Reserve Capacity under Ice and Snow Condition

Abstract:

To study the reserve capacity of city road network under ice and snow condition，the upper programming model was build on the basis of travelers’ demands on level of service, which was incarnated on capacity of links, and travel time reliability, while user equilibrium (UE) was set up in the lower programming model. Then, sensitivity analysis was applied to solve the bi-level programming model under ice and snow condition. At last, one simulation network example was given to demonstrate the practicality of the given model, and the result showed that the ice and snow condition and the travelers’ demands on level of service had great impact on the road network reserve capacity. The methodology is useful and applicable to evaluate road network under ice and snow condition and lays the foundation for capacity reliability.
