Route Choice Decision based on Real Time Information

The aim of this study is to find out the travel time between the zones by different routes of the study area and discover the shortest travel time which is calculated by using the online data. In this study the OD matrix of the flow is updated in each loop of the algorithm by using the double constraint gravity model and traffic assignment, also the delay time of the intersections are calculated. The calculated travel times are capable for informing the traveler on the internet or other Medias for letting the traveler to choose the best travel route. The data required for this study are collected from Closed Circuit Television (CCTV) and the program is written with Visual Basic.NET (Microsoft, 2008). Users of this program are capable for selecting their origin and destination and they find out the travel time, the length of the route and different possible path is illustrated by different color on the figure for the users.
