Both bus dwell time and bus headway adherence are critical to the serviceability of the bus transit system. It is acknowledged that passengers with physical disabilities may greatly impact bus dwell time and bus headway adherence due to the increased time needed to safely board the bus. However, the mitigating effects of securement systems and ramp...

Age related declines in ability and function are well documented in the literature. Adults over the age of 65 have reduced strength and range of motion (ROM) as compared to the younger population. Aging therefore can lead to difficulties completing tasks of daily living. Older adults cope with excessive physical demands by modifying the way they pe...
