Sustainable assessment factors for construction site selection of semi-automatic parking systems

Purpose Global population growth and rising automobile ownership have led to an increased demand for parking spaces, particularly in urban centers. Many cities worldwide have adopted semi-automatic parking systems (SAPS) because of their numerous advantages, such as rapid construction, compact design and space efficiency. However, selecting optimal sites for SAPS remains a significant challenge for local authorities and transportation planners, particularly in Vietnam, where SAPS’s specifications align well with local needs and features. This study aims to identify the critical sustainable criteria influencing the location selection of SAPS. Design/methodology/approach A comprehensive list of potential factors, including four dimensions: society, environment, economy and technology, was established. A set of 18 factors affecting the site selection of SAPS was identified based on the relative importance index, which was rated using an expert survey. The weights of the identified factors were then computed using the fuzzy analytical hierarchy process (FAHP) technique. Findings The findings of this research provide a comprehensive framework comprising four main factors and eighteen sub-factors, aimed at guiding local authorities and private enterprises in selecting the optimal site for SAPS, thereby enhancing operational efficiency and promoting urban sustainability. Originality/value Develop a set of sustainable criteria to aid decision makers in selecting the appropriate location for SAPS during the feasibility study stage prior to construction.
