Perceived Factors Affecting Driver Route Decisions

Abstract
In this study, the route choice reasons of drivers making automobile work trips are analyzed in order to gain an insight into driver's route choice perceptions. Statistical analyses of 32 route choice reasons are carried out by four methods: frequency analysis, correlation analysis, grouping techniques, and factor analysis. Analyzing the frequency of responses shows that there was not a single common pattern of the more important route selection reasons. The drivers often perceived four to six reasons together as the criterion for route selection. By using grouping techniques and factor analysis, the 32 reasons are consolidated into six comprehensive dimensions. The study of the factor scores shows that although most respondents used the same route to and from work, they did not always rank the route choice reasons with the same Weight for each direction.
