Abstract:

Trip decisions are complex and involve choosing the activity destination, the mode and subsequently the route for travel. This paper presents detailed information on the pre-planned and observed route choices for the home-to-work commute. Specifically, the study examines how people formulate their route plans and describe their attitudes and preferences for their selected route. A geographical information system (GIS) records the pre-planned route information with the route planning sequence. Observing route choice is a difficult procedure; however, through the use of the global positioning system (GPS), one can accurately record route choice. An automated activity-trip detection algorithm processes GPS data and displays results within an internet-based prompted recall diary. The diary is used to verify trip start and end times. This combination of GPS, GIS and diary responses provide great insight into the route choice decision-making process. Twenty-four individuals from Ontario, Canada participated in answering survey questions and the collection of person-based GPS data. Results indicate a preference to minimize travel time as stated by participants in deciding what route to travel. Participants also affirmed a desire to minimize the number of stop lights/signs, as well as, avoid congestion and maximize route directness. A comparison between pre-planned and observed routes, reveals about one-fifth of participants deviated from their pre-planned route. This study demonstrates the need for qualitative and quantitative survey methods for exploring pre-planned and observed route choice patterns.
