Abstract:
The objectives of this research are to examine the impacts of various parking measures on parking behavior and to formulate optimal parking management policies for Siam Square Shopping Center, located in a major commercial district of Bangkok metropolitan area. The research methodology consists of two analytical techniques. First, the discrete choice technique was used to analyze the Stated-Preference behavioral responses to parking measures, such as an increase in the rate of parking fee. Combinations of various measures and the resulting aggregate behavioral responses were then analyzed by the Analytical Hierarchy Process technique in order to select the optimal set of parking management policies. By using parking fee and searching time as factors in the SP questionnaires, the results show that when the rate of parking fee is raised, parkers are more likely to change their parking locations than to switch to public modes or to travel to different locations. Evaluation by AHP, based on opinions of the administrator of Siam Square, shows that the most suitable set of parking policies for the area is to increase the rate of parking fee to 15 Baht per hour, to establish a short-term parking lot, and to limit parking privileges of the tenants.
