Abstract: To solve the problem of travelers departure time choice considering insufficient parking space, based on perspective of bounded rationality, the road congestion situation, traveler personal perception differences, destination parking status, lack of the legitimate parking spaces and other factors were taken into account to analyze the influence of departure time choice of travelers. Based on prospect theory, the experiment was designed to investigate the intention of the traveler at departure time choice. It is shown that the traveler's satisfaction with the travel result and the decision of the next trip are related to the residual status of the parking space after the traveler arrives at the destination. With the decrease of the supply rate of the remaining parking spaces, the satisfaction degree of the traveler is reduced. When the travel result of the traveller is satisfied, the traveler's next trip decision is from early arrival to late. In the cases that the traveler can't park at the legal parking spaces, different penalty measures lead to different decisions of traveler for the next departure time decision. The more severe punishment measures are the more inclined to a traveler's earlier departure.
