Abstract
Expected travel time information on variable message signs (VMS) supports even capacity utilization on the road network. To justify the importance of VMS in urban traffic, general user attitude to VMS was assessed and route choice decisions were investigated through stated preferences. Logit model was used to show how route choices are affected by changing expected travel time, reliability of travel time, and perceived travel time of alternative routes. Applying logistic regression, functions were defined that describe the sensitivity of route change depending on expected travel times.
