More Urban Form, Fewer Auto Trips, Kelly J. Clifton

TREC Project Briefs

Trip generation refers to the number of vehicle trips that are predicted to originate in a given zone. The Institute of Transportation Engineers (ITE) publishes standard trip generation rates for various land use types, but these rates are primarily measured in low-density suburban areas. There is national interest in building data that expands upon the existing ITE trip generation rates to include sites located in a multi-modal context.

In areas that have a more compact urban form, better access to transit and a greater mix of land uses, fewer vehicle trips may be generated there than ITE rates indicate. However, …

How Livable Is Your Transit System?, Marc Schlossberg

TREC Project Briefs

The U.S. Department of Housing and Urban Development has identified some “livability principles” which include healthy, safe and walkable neighborhoods and safe, reliable and economical transportation choices. Transit agencies and local governments routinely use metrics to evaluate the performance of transit systems, but a uniform standard of transit data collection does not exist outside of the reporting requirements of the National Transit Database (NTD). Because of the types of data collected for the NTD, the focus of performance measurements is often on ridership and financial performance, leaving aside the question of livability.

In an OTREC-sponsored project, principal investigator Marc Schlossberg …

Transportation Meets Social Welfare, Ellen M. Bassett, Andrée Tremoulet

TREC Project Briefs

OTREC researchers helped state transportation department staff members face a problem that isn’t strictly part of their job description: how best to deal with homeless individuals and households living in DOT rights of way and rest areas.

OTREC researchers examine the human relations impact of transportation and land management decisions involving homeless encampments.
