We developed and applied a tool to: (1) quantify spatial access to HIV care services (supply) and (2) identify underserved areas with respect to HIV cases (demand), by travel mode, in Atlanta. METHODS Building on a study of HIV care engagemen...

We treat this crisis as a natural experiment illustrate the importance riders’ abilities access essential destinations. measured impacts riders forgoing through survey transportation barriers completed by more than 4,000 Toronto Vancouver (Canada). used Heckman selection m...

Seamless integration of ride-sharing and public transit may offer fast, reliable, and affordable transfer to and from transit stations in suburban areas thereby enhancing mobility of residents. We investigate the potential benefits of such a system, as well as the ride-matching technology required to support it, by means of an extensive computational study.

BACKGROUND Walking for transport can contribute to the accrual of health-enhancing levels of physical activity in elders. Identifying destinations and environmental conditions that facilitate this type of walking has public health significance. However, most findings are limited to Western, low-density locations, while a larger proportion of the global population resides in ultra-dense Asian me...

Cost-effective public transit options suitable for serving all demand levels include: bus service in mixed traffic, bus service in reserved lane, transitway/buswdy, light rail transit (LRT) (segregated right of way), intermediate capacity advanced light rail transit (ALRT), and heavy rail rapid transit. This classification of transit options takes into account right-of-way access (that is, mixe...
