ABSTRACT
The development and implementation of advanced traveller information systems (ATIS) to best serve individual drivers and to maximize system performance, however, involve many issues. Knowing drivers' perception and preferences of route attributes is important to determine how additional information provided by ATIS may affect their route choice. The travel environment was generated by a probabilistic assignment of travel speeds and stop delays to the network links and nodes. Incidents were generated randomly and assigned with random severity for each simulated travel day. The exact commute route by roadway segment, travel time, and other commute attributes were available for each respondent from the preceding two computer aided telephone interview surveys. Subjective perceptions of route attributes affected route choice, with perceived travel time reliability and traffic condition being significant along with travel time and number of roadway segments in the commute route.
