In this study, the authors emphasize the advantages of two new equity measures, developed in previous work, through a real world evaluation of transport project. The authors use the San Francisco Bay Area case study and its regional activity-based travel model estimation. The authors' first approach utilizes the concepts of accessibility and subjective well-being, rather than value of time, to measure gains from transport investments. The authors develop the “Subjective Value of Accessibility” (SVOA) measure, a utility-activity based accessibility measure combined with a well-being factor. The authors' second approach utilizes the “capability approach” (CA), which is derived from the actual opportunities that people have, given their personal and social circumstances. The authors estimate the “Value of Capability gains" (VOC) as the key benefit taken into account in Cost-Benefit Analysis (CBA). This new VOC measure relies on what the authors refer to as the Activity-Based Capability (ABC) measure, which is an Activity-Based Accessibility measure (ABA) calculated from the actual opportunities a person can access. The authors' case study results indicate that the SVOA and the VOC can reveal higher benefits from policies focusing on the needs of more vulnerable social groups, as compared to the result obtained using the traditional measures.
