Key Determinants of the Efficiency of Transportation Services for the Disabled

The demand for demand-responsive transit (DRT) services has continuously increased for vulnerable transport users such as the elderly and disabled. DRT operators must maximize efficiency because their fares are regulated by law despite their high operating costs. Although a comprehensive evaluation of the efficiency of DRT services is imperative, little work has been done in this area. The main objective of this research is to identify the variables that significantly affect the operational efficiency of DRT service providers and propose ways to improve the competitiveness of DRT services. This study presents a new approach to analyzing the efficiency of DRT operators and investigating the determinants of their efficiency. The results indicate the significant impacts of minimum reservation time, maximum reservation time, and operational experience on efficiency. Unlike previous studies, however, ownership type does not significantly affect efficiency. This study presents guidance for policy makers and managers who want to develop transparent management strategies.
