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... Read More

Data and Methodological Issues in Assessing Multimodal Transportation Impacts for Urban Development

Kristina Currans
In 1976, the Institute of Transportation Engineers (ITE) compiled their first Handbook of guidelines and methods for evaluating development-level transportation impacts, specifically vehicular impacts (Institute of Transportation Engineers 1976). Decades later, these methods— essentially the same as when they were originally conceived—are used ubiquitously across the US and Canada. Only recently, with the guidelines in its third edition of the ITE’s Trip Generation Handbook (Institute of Tran... Read More
