Cognitive cost of real time traffic information search in route choice

Project Number: 169

Project Leader: Emma Frejinger

Start Date: 2011-01-01

End Date: 2011-06-30

Real-time traffic information is increasingly available to support route choice decisions pre-trip and en-route. Travellers can, for example, listen to radio broadcasts for incident information or check websites displaying actual speeds on highways and main arterials. They can also consult other information sources, for instance, weather forecast or special event schedules. By acquiring information travellers can estimate the actual travel time for a given path and departure time instead of relying on the average travel time (e.g. gained through experience or given by a travel information system using links' mean travel times). Because of time constraints and limited cognitive capacity, a traveller cannot assess all available information on all alternative routes.
