The primary objective of this study was to investigate which attributes of HappyCar, a closed carsharing service implemented in rental housing complexes in South Korea, should be improved to become an alternative transportation mode for low-income households. The study also aimed to identify what kinds of characteristics of rental housing complexes influenced the vehicle usage rate. For the analysis, two types of data were collected: survey data from carsharing members and operation record log files provided by a service operator. For the methodology, the study employed an importance-performance analysis (IPA) technique to analyze which attributes of HappyCar require improvement. A beta regression model was estimated to identify factors affecting the vehicle usage rate. The IPA results showed that three attributes-the appropriateness of rental rates, thorough vehicle maintenance, and increase in the number of vehicles operated-should be improved with top priority to make the HappyCar service more convenient and comfortable. Five variables were found to be associated positively with the vehicle usage rate: rental housing type, number of households per complex, ratios of one- and two-person households, and ratio of five or more person households. The study enabled a better understanding of the characteristics of carsharing, including use by low-income residents in rental housing, and provided recommendations for HappyCar service providers and traffic policy decision makers.
