中文摘要：

为研究出行者在可变导行信息影响下的宏观行为规律,把出行者分为传统型、固定路径型、理性型、用户均衡型、系统最优型以及VMS（可变信息标志）型,基于VISSIM微观仿真器,利用COM接口开发了各类出行者的出行效益评价模型,最后以小型路网为例,针对VMS型用户进行可变导行信息的有效性评价。研究结果发现：基于仿真的模型可以对不同的可变导行信息进行有效性评价;相同交通需求下的有无对比表明,VMS的设置可以有效降低路网主要干道的行程时间,行程时间降低21%;不同交通需求下的有无对比表明,VMS信息可以提高路网的平均速度,路网平均速度提高约3.97%。

英文摘要：

In order to study the macroscopic behavior of travelers under the influence of guide information,travelers were divided into six groups according to their behavior characters： Traditional（TR）,Pre-Specified paths（PS）,Bounded-Rational（BR）,User Equilibrium（UE） routes followers and System Optimal（SO） routes followers,and Variable Message Sign（VMS） users.Based on VISSIM simulator,the effectiveness evaluation models of every driver types were developed through COM interface.Finally,in the case of a small network,the effectiveness of dynamic guide information for VMS-drivers was evaluated.As a result,simulation-based model can evaluate various types of guide information.With and without comparison under the same traffic demand indicates that VMS can reduce travel time of main arterials,the travel time is decreased 21%.With and without comparison under various traffic demands indicates that VMS can increase the network speed,the average speed is increased about 3.97%.1 tab,5 figs,10 refs.
