research >>Effects of Transportation Corridor Features on Driver and Pedestrian Behavior and on Community Vitality

ongoing

The purpose of this study is to identify quantifiable performance measures for transportation corridor design features related to safety, economic vitality and community quality of life. The results will support the California Department of Transportation's (Caltrans') planning, design and implementation of transportation corridors that are responsive to the contextual environments of partner communities and will provide a model for transportation and urban planners and designers.

A key aspect of the study will be to identify a corridor on which we will conduct research that collects data on performance measures identified in previous research. Initial roadway types for study are arterials and "main street" highways, with a focus on roadways that are within Caltrans' jurisdiction. The study will investigate how individual design features and the shaping of whole environments can influence and result in specific behaviors and benefits.

The research study features a thorough review and analysis of research literature and best practices. We will establish an Advisory Group composed of Caltrans employees and leading experts in the field to understand the issues, needs and opportunities associated with transportation corridor design. The Advisory Group will assist in shaping relevant performance measures and framing new approaches to evaluating costs and benefits of investment decisions in state highway system right-of-ways and associated community environments. The study will also identify innovative practices, gaps in the research and directions for further research.

Elizabeth Macdonald Ph.D., Assistant Professor of City and Regional Planning, leads the research team.The project began on June 1, 2007, and runs for three years. Funding is provided by Caltrans through the University of California Transportation Center (UCTC).
