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...

Understanding Types of Cyclists Nationally
Jennifer Dill
Nathan McNeil
Transportation professionals who are developing plans and projects that aim to change people’s travel behavior – such as getting more people to bicycle – need to understand the people they are targeting. To do so, planners and researchers have developed typologies of cyclists; however, many of these typologies are based upon surveys of current cyclists and, therefore, are of limited use in planning to attract new people to bicycling for transportation. One exception is the “Four Types of Cycl...
