摘　　要：运用模拟的方法,研究了在拥挤条件下VMS交通诱导信息对驾驶行为的影响,得出如下结论:①VMS交通诱导信息的提供位置对交通信息的作用有很大的影响。如果交通诱导信息被合理地提供给驾驶员,路网交通的运行状况将有较大改善,其中延误减少23.7%,停车时间减少31.8%,停车次数减少38.7%;②路网交通运行状况的改善取决于所推荐的替代路径的质量。如果替代路径的质量较差,拥挤现象不但不能得到缓解而且会进一步恶化,并且在替代路径上会形成新的拥挤;③左转次数和左转通行能力是决定替代路径质量的两个关键因素。无论是以出行时间还是出行距离为依据选择替代路径,都应该考虑左转次数及左转通行能力的影响。The benefits of the route guidance information from variable message signs （VMS） and the congestion shifting phenomenon owing to the inappropriate offering of route guidance information were discussed using the simulation software,VISSIM. The important conclusions are： ①the location of VMS has great impacts on the effect of the route guidance information. If VMS route guidance information is disseminated appropriately, the performance improvement of the road network could be up to 23.7 % （ delay reduction）, 31.8 % （ accumulated stop time reduction ） performance improvement of the road network depends on and 38.7 % （stop frequency reduction）. ②The the quality of the recommended alternative route. If the alternative route quality is not satisfying, the congested area would not be ameliorated but deteriorated and new congestion would be produced at the alternative route. ③The frequency of the left turns and their capacity are two critical factors signifying the quality of the alternatives. This implies that the criteria should include the frequency of the left turns and their capacity besides travel time, travel distance and so on when the alternatives are selected.
