Enabling Decision-Making in Battery Electric Bus Deployment through Interactive Visualization
Xiaoyue Cathy Liu Jianli Chen
Encouraged by the advancement of battery technology, the transition from diesel or compressed natural gas to fully zero-emission bus fleets has been the trend in the United States. Policymakers and transit agencies have set up goals to accelerate such transition, yet various challenges that are, by nature, institutional, technological and/or financial still present themselves.

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…
