A study of shopping trip parking behavior using choice model

To establish an effective parking management policy, it is essential to understand how drivers make their decision on parking. This study models the parking choice behavior of drivers who make a shopping trip to Siam Square, Bangkok, Thailand. The parameters are estimated from the result of stated preference questionnaires in the form of utility function. Data were successfully collected from 228 decisions of 76 respondents. The study found that the drivers who park from 0 to 3 h make decisions based on similar factors and sensitivity. The most influential factors included the parking fee and walking distance. Meanwhile the long-term parking decisions were based on the aforementioned 2 attributes and also the search time.
