ATIS和道路收费下的混合随机用户均衡的效率损失
Bounding the Inefficiency of Stochastic User Equilibrium under ATIS and Road Pricing
摘要
Abstract
In a transportation network under the Advanced Traveler Information Systems(ATIS),users are heterogeneous in terms of different traffic information received.Users equipped with ATIS do not always follow the ATIS advice,and therefore,based on the information compliance rate,all users are divided into three groups:users with ATIS and in compliance with ATIS advice,users with ATIS but without compliance with ATIS advice,and users without ATIS,all of which follow the stochastic user equilibrium (SUE) principle but with different perceptions of travel time.While road pricing exists simultaneously,users are heterogeneous in terms of different value of time(VOT).Based on the heterogeneities of the two aspects,all users are divided into reasonable classes.In this paper,a multiclass mixed SUE model under road pricing and its equivalent variational inequality are established.While tolls are not considered as part of total system costs,the multiclass system optimum (SO) models under time units and monetary units are presented.Then,the inefficiency of mixed SUE against the SO are investigated;a further analysis is made on the effects of the parameters influencing the upper bounds;the conclusion is meaningful for the manager in network design and optimal control from the perspective of the implementation of the road pricing and the improvement of the information system.关键词
