Abstract
Emerging transportation technologies (e.g. connected vehicles) and services (e.g. shared mobility) provide efficient, sustainable and cost-effective alternatives to traditional travel modes. However, whether these innovative technologies bring benefits to different population groups in an equal and reasonable manner is still an open question. This report aims to tackle this question and is divided into the following two parts: transportation equity literature review and a case study on bike-sharing systems. The first part of the report comprehensively surveys the literature about methodologies for analyzing transportation equity for traditional and emerging transportation technologies in terms of economy, environment and public health. It is found that existing methodologies can be unified into a 3-step equity analysis framework. Research gaps and future research directions are also discussed. The second part of the report closes one of the research gaps mentioned in the first part of report by using disaggregated data for equity measurement. This part of report developes a comprehensive equity assessment framework on bike sharing accessibility in southern Tampa with individual-level data. The report compares the equity outcomes of the proposed approach and serveral benchmarks, and interpretes results of horizontal equity and vertical equity analysis. The results justify the importance of using disaggregated tour data, also reveal some equity issues in southern Tampa.
