Revisiting Travel Time in Mumbai: Value of Time Saving or Value of Access?
This study analyzes the association between travel time and the individual capability (i.e., all the opportunities he/she can undertake actions and activities, given economic, social, and mobility constraints) in Mumbai. The authors first formulated a conceptual hypothesis based on Becker’s time allocation theory to understand differences between the consumption and production aspects of travel. Then, two operationalized hypotheses are introduced for empirical verification: (1) travel time is significantly related to individual capability and is lower for less capable, and (2) the variance of travel time, indicating the degree of freedom of movement, has positive association with individual capability. To empirically confirm the hypotheses, an activity-travel survey was conducted in middle income group housing, slums, and slum rehabilitation units. The authors' results support both hypotheses, suggesting that, when people are less capable, they attach more importance to the production aspects of travel, and gradually with the increase in their capability value on the consumption aspects become more vital. Hence, the value of travel time saving may underestimate the benefit from transport infrastructure investment especially for less capable people. Therefore, including the value of access in transport infrastructure evaluation would make it more inclusive.
