How does the built environment influence the amount people drive? Research by SSTI’s Logan Dredske worked to answer this very question. The focus of his research was to create a framework for estimating vehicle miles traveled based on conditions of the built environment. His goal was to use measures of accessibility as the principal proxy for the built environment. The research also converted vehicle miles traveled into greenhouse gas emissions and evaluated the ability of transportation projects to reduce emissions.
Bicycle level of stress and equity as factors in project selection
A paper published in the International Journal of Sustainable Transportation suggests integrating accessibility by bicycle, equity, and project selection to tackle the isolation and segregation of low-income neighborhoods in Baltimore. Using bicycle Level of Traffic Stress (LTS) to measure both access to common non-work destinations and disparities in access across different neighborhoods, the authors suggest that projects can be prioritized to improve outcomes for residents that do not own cars and struggle to reach destinations to meet their daily needs.
Accessibility in practice: A new guide from SSTI
The Virginia Office of Intermodal Planning and Investment recently released its new report, Accessibility in practice: A guide for transportation and land use decision making, developed by SSTI with several partners. The guide describes ways of measuring accessibility and, more importantly, how to use those metrics in planning, project evaluation, and other transportation and land use decisions. The information is useful for any state or local agency interested or already involved in making these kinds of decisions.
A viaduct or a wall: I-81 in Syracuse
Interstate 81, known locally as “the viaduct”, slices through the middle of Syracuse in upstate New York. The aging, elevated freeway effectively forms a barrier between the city and the Syracuse University neighborhood known as the Hill. A coalition of local businesses, education, and political leaders have come together to solicit input on whether to rebuild, replace, or remove the freeway. The process could serve as a model for other communities wrestling with a similar decision.
