Research Highlights
Equity Outcomes and Potential for Better Bike Share
John MacArthur
Nathan McNeil
In a mere ten years, public bike-sharing systems have exploded from operating in a few select European cities to expanding in North America at a pace of nearly two dozen cities per year in recent years. The majority of academic research to date has focused either on the complex logistics of designing and operating systems or else on broad comparisons across systems. Investigations of system users and local impacts have only just begun. As cities plan and launch their systems, a tension has ar...

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors
Miguel Andres Figliozzi
Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian interactions, are not well understood. When the focus is on motorized vehicle mobility and throughput, high traffic or vehicle speeds are desirable because at high speeds more vehicles can flow per unit of time and roadway section. However, high traffic/vehicles speeds are not desirable for pedestrians who have to cross urban arterials. In parti...
