The results, based on use of a conventional traffic assignment model are illustrative only, indicating the probable direction and scale of the effects. The general indication is that the use of Autoguide in London will offer traffic benefits which will be most substantial for vehicles equipped with an Autoguide unit, but there will also be benefits for non-equipped vehicles; there should be no adverse impacts.<<ETX>>","PeriodicalId":366041,"journal":{"name":"Conference Record of papers presented at the First Vehicle Navigation and Information Systems Conference (VNIS '89)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131571848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different freeway and arterial incident scenarios were examined and, for each scenario, the impact of having various percentages of drivers equipped with a route guidance system was investigated. The incremental benefits of route guidance are found to be greatest for the first 20% of drivers with in-vehicle units, but further benefits continue to be obtained when the market penetration increases up to 100%. These benefits are the largest for incident scenarios, and increase with the duration of the incident. It is speculated that for normal traffic conditions only a few drivers need to reroute themselves to maintain an equilibrium assignment. However, an incident causes a greater disturbance in the equilibrium and therefore requires a greater percentage of drivers to reroute themselves before the new equilibrium can be reached.<<ETX>>","PeriodicalId":366041,"journal":{"name":"Conference Record of papers presented at the First Vehicle Navigation and Information Systems Conference (VNIS '89)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129698412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
