Connectivity is good for walkability, but social factors also matter

By Saumya Jain Most efforts to increase bike and walk accessibility focus on physical access. But the built environment is not the full story. A new study finds that certain attributes of the social environment also greatly affect the perception of walkability, especially among people of

Invisible women

By Beth Osborne Research and design are based on a test case human who stands in for the broader population. The default human that is the basis for research and design projects is usually a white adult male. As a result, projects often come to conclusions that do not address the needs of women,

AVs: Some intersections may get more dangerous before they get safer

By Michael Brenneis Many imagine a future with fleets of autonomous vehicles seamlessly traversing road networks, wirelessly connected, perfectly aware of their surroundings and other vehicles, expertly avoiding conflicts. But what happens during the transition from manually-driven to

Why are they Snapchatting while driving, and what will get them to stop?

Active transportation fatalities spike again

By Robbie Webber Although cars are getting safer, saving drivers and passengers from dying on our roads and highways, the number of pedestrian and bicyclist deaths are increasing dramatically. The latest numbers from the National Highway Traffic Safety Administration Traffic Safety Facts show
