Parking Utilization Behavior in Samyan Mitrtown Mixed-Use Project

Abstract

The development of mixed-use real estate Samyan Mitrtown projects necessitates the provision of parking facilities in accordance with applicable legal frameworks, particularly Ministerial Regulation No. 7 (B.E. 2517) and the Bangkok Metropolitan Administration Building Control Regulation (B.E. 2544). Efficient parking allocation requires assessment of actual supply, user behavior across functional areas, and temporal utilization patterns. This study employed a structured methodology, including a literature and legal review, analysis of Environmental Impact Assessment (EIA) reports, and evaluation of 556,953 parking usage records classified into five functional areas.

The project provided 1,648 parking spaces, slightly exceeding the legal requirement of 1,638 based on the designated building function areas. The peak average weekday parking utilization occurred at 13:00 hours, reaching 81% of the number of provided parking spaces. During this period, parking demand in office areas declined steadily, while commercial areas usage increased, indicating an inverse usage trend. On weekends, the peak average occurred at 13:00 hours (63%), while on public holidays it peaked at 14:00 hours (57%). Notably, during both weekends and holidays, parking demand in office and commercial areas moved in the same direction—either increasing or decreasing simultaneously.

These findings align with user visitation patterns and highlight the temporal heterogeneity of parking demand across building functional areas. They affirm the applicability of the shared parking paradigm as that can enhance the efficiency of space utilization to appropriately accommodate diverse needs.
