Join us for Yang (Luna) Xi’s MASc thesis presentation, “Logit-based accessibility measures: A destination-mode choice model for morning-peak commuting in the GTHA.” All are welcome.

Abstract

Accessibility has been a popular indicator for measuring system performance and policy effects in the transportation planning field, however, the measurement of the accessibility itself remains controversial.

This study proposes utility-based accessibility measures to evaluate the morning-peak access to workplaces in the GTHA by building a nested destination-mode choice model. Eight sets of parameters are estimated for full-time and part-time employees with an occupation type of General, Manufacturing, Professional, or Sales.

The workplace accessibility results indicate a significant difference between the employees with different occupation types as well as between full-time and part-time employees. Spatial variation is further examined, and distinctive patterns of workplace accessibility are observed for the employees in different occupation groups and employment statuses.

The contribution of this study is the proposal of occupation-specific workplace accessibility measures, which allows to evaluate equity and identify gaps within each group as well as across the groups.
