Study on Road Network Reserved Capacity on Different Levels of Serviceand Stochastic Conditions

摘要

The paper investigates the road network capacity under uncertainty. Byrnshowing the characteristics of route choice and considering the link travel timernreliability on a certain level of service, we set a bi-level programming model andrnthe road network capacity can be gained. Firstly we consider the single link of arnroute under uncertainty, and then extend it to the whole road network capacity onrna certain service level. Using the model we can escape from calculating a hugernamount of data which is used in the Monte-Carlo method. An example isrncalculated, and then the result shows the efficiency of the model.
