Abstract

This research is to study trip generation rates and the factors influencing trip generation at six shopping malls, three located in urban areas and three in suburban areas, located next to the Thai National highways. The analysis shows that a mall’s trip generation rate is directly related to its gross leasable area. Overall mall traffic peaks on Sundays, with the highest volumes occurring in two one-hour periods: 13:00–15:00 and 16:00–18:00, which coincide with the afternoon peak on the surrounding road network. Parking demand also reaches its maximum on Sundays.

In addition, this research disaggregates trip generation into three categories—new trips (Primary Trips), pass-by trips, and diverted trips—based on interviews with patrons at all six malls. The results indicate that Primary Trips constitute the largest share of all trips, accounting for approximately 85% of total trips on Sundays
