Route Choice Modelling for Urban Commuters: Considering Bridge Choice as a Key Determinant of Selected Routes

Trip assignment is still a modelling and prediction challenge. For aggregate analyses, traditional trip assignment approaches may suffice. However, investigations of drivers’ choices with respect to network infrastructure changes require more disaggregate and behavioural approach. Effects of critical infrastructure elements in the network on route choice behaviour of the drivers are often crucial to investigate. The case of Montreal is of particular interest since the city, an Island, is completely separated from the rest of the region by two important rivers. Consequently, drivers have to select one of the available bridges to reach their destination. The research relies on a set of observed trips with bridge declaration from a large-scale travel survey conducted in 2008. It is a one-day trip diary reaching some 4% of the residing population and including the bridge chosen in the itinerary for car driver trips. The paper provides a descriptive analysis of the bridges and their usage. An advanced discrete choice model that jointly models choice set formation and final choice is then formulated and estimated using the observed trips. Empirical model correctly identifies effects of travel time interacting with time of day and destination trip purpose. Travellers are more sensitive to travel time during off-peak period. Empirical results show that age, gender and household auto ownership explain the variation of scale parameters of route/bridge choice; for instance, older people show more stable route/bridge choice behaviour than younger ones. Discussion on the performance of the model is provided along with further result analysis and perspectives for further work.
