THE LOGIT TYPE ROUTE CHOICE MODEL'S VERIFICATION BY TRAFFIC FLOW OBSERVATION RESULT

Abstract

In order to provide an effective infrastructure, to make the congestion easier, and to manage the traffic demand, and to achieve the comfortable traffic circumstance, it is necessary to understand the characteristic of driver's route choice, and to select the appropriate route selection model actually suited in a comparatively narrow area in the urban area.
In this study, from the result of the survey of the route choice behavior in the real traffic, it is clarified that the drivers choose the route according to various factors not only the travel time but also the width of the road and the number of signal intersections etc., and verified adaptability with an existing Logit type route selection model based on the characteristic of the route choice behavior of such as the drivers. As a result, it turned out to suit the MNL model most, and to suit the C-Logit model next. Moreover, to attempt the accuracy improvement of the route choice calculation, it proposes the calculation method that takes the situation in the road and the route into the effect.
