User Characteristics and Effectiveness of a Park and Ride Facility in Bangkok
An experimental project was initiated in Bangkok in 2015 to set up Park and Ride facilities near transit stations as part of an effort to encourage transit use. Incentives were offered to prospective users, including free one-month trial and free transit trips. This paper provides evidence on user characteristics of one of the facilities and its effectiveness in time savings and reducing car travel. After the free-trial period ended, approximately 45% of the users discontinued their use. The results from interview surveys of both continuing and discontinued users confirm time savings and reduction in car travel for a majority of users who had relied solely on cars before the modal shift. But car travel distance increased for users who previously drove to other facilities or used public transport to access transit stations. The catchment area is found to be 23.6 km. We also developed a logistic regression model of the decision to continue using the facility even after the trial period. The modeling results imply that travel time and driving distance before and after using Park and Ride clearly influence decision-making. Users with longer travel time and driving distance before using Park and Ride tend to continue using the facility.
