Precision of Predicted Travel Time, the Responses of Travelers, and Satisfaction in the Travel Experience

Imagine that people wish to travel from point A to point B by auto, and want to arrive at point B at the same desired time. The predicted travel time from point A to point B is given prior to the trip in the form of range of time, and each traveler chooses hi/her departure time. How one chooses a specific departure time, however, depends on one’s attitude towards meeting the desired arrival time. The less precise the predicted travel time is the travelers will have a greater band of time to choose the departure time from. On the other hand, the more precise the perceived travel time is (a narrow range), the narrower the band of possible departure times becomes. The latter case allows the departure times to concentrate, which in turn may make the average travel time of all travelers long due to congestion. This paper is motivated by the question of how precise the predicted travel time (PTT) needs to be in order for it to be meaningful. Based on a simple setting, in which a group of people travel from one origin to one destination on a one-lane roadway, and wish to arrive at the same desired time, the paper has examined the relationship between the precision of PTT and the satisfaction of travelers, measured by the travel time, time-missed, and the match between the desired and actual arrival times.
