GPS导航下城市网络的SUE配流问题

随着科技的进步和小汽车保有量的增长,有GPS导航的汽车在城市网络中的比重越来越大。通过将出行者分为两类：使用GPS导航和不使用GPS导航,考虑GPS对出行者道路选择行为的影响,构造随机用户均衡模型来描述GPS导航条件下的路径选择问题,并设计相应的算法。最后给出算例对模型及算法进行论证,得出可靠的GPS导航比重是使配流结果理想的关键因素。

Stochastic User Equilibrium Model for Traffic Assignment under GPS Navigation

With the advancement of technology and the growth of car,the proportion of car which has GPS navigation is increasing.In this paper,two classes of drivers are considered,who are drivers with GPS and drivers without GPS.In allusion to the influence of GPS on the route choice of traveler,a multi probit-based SUE model is formulated to describe the problem,and an iterative solution algorithm for solving this problem is presented with the use of a numerical example.It is proved that reliable proportion of GPS n...
