Research Highlights
Access to Opportunities: Redefining Planning Methods and Measures for Disadvantaged Populations
Arlie Adkins
Stephen Mattingly
This project will be made up of two separate studies that together will investigate areas where transportation planning and engineering can better serve disadvantaged and underserved communities. An interdisciplinary team of planning and public health researchers from UA will investigate how standard measures and conceptions of walkability hold up across socio-economic contexts. Pilot data from a CDC-funded project suggest that many standard measures of walkability may miss important elements...

NCHRP 15-73 Design Options to Reduce Turning Motor Vehicle – Bicycle Conflicts at Controlled Intersections

BACKGROUND
One of the most common locations for fatal motor vehicle-bicyclist crashes is at intersections, which inherently have a large number of turning conflicts. Reducing these conflicts is a key objective in improving intersection safety across all modes. Of particular concern for bicyclists’ safety at intersections are the conflicts between straight-through bicyclists and motor vehicle right-turns and opposing left-turns. Despite the widespread acknowledgement of this problem, trans...
