A Route Choice Model between Expressway and Ordinary Road for Business Truck Operators Considering Contracts with Consigners

Abstract

Though business truck operators finally make decisions on route choice between expressways and ordinary roads, contracts with their consigners must affect their decisions. In this research, we first conducted hearing survey on operators and confirmed that contracts influenced the route choice behaviors. In addition, there are some operators which don't obtain enough profit and cannot use expressways without considering expressway tool or travel time. Based on the results of the interview survey, we conducted SP survey on route choice for all companies except Sado area and coffin carriers which join the Niigata Prefecture Truck Association, Finally, we propose two models: one is a binary logit model and another is a captive-conscious route choice model considering the relationship between operators and consigners, and confirm that the later model is better in terms of the likelihood ratio, and attributes of operators can distinguish captive group and selective one.
