A proactive route planning approach to navigation errors

Abstract

Online navigation systems assume a person can follow a given route from origin to destination. Nonetheless, spatial cognition studies show that wayfinding is a complex, highly adaptive process and that route planning is incremental rather than prescriptive. Indeed, people may deviate from their originally chosen route for a number of reasons including navigation errors, especially when the environment is unfamiliar. Even in familiar places, certainty in wayfinding is highly unlikely to be completely achieved. Consequently, when people make a wrong turn or miss an exit, even the best reroute to the destination may add several minutes to the originally planned travel time. This work formally d..
