At the May 2013 SSTI Community of Practice, participants requested guidance on performance measures for biking and walking projects. After surveying state DOTs, city and MPO staff, national organizations, and the research literature, this draft report outlines strategies used to assess the success of state and local projects.
This report presents recommendations for bicycle lane widths for various roadway and traffic characteristics, including traffic volume, vehicle mix (i.e., percent trucks), lane width and/or total roadway width, and presence/absence of on-street parking. It examines narrow and wide un-protected bike lanes as well as lanes protected with barriers. The report provides guidance on the safety of each lane option for bicyclists.
Massachusetts’s Regional Transit Authorities have an opportunity to improve their existing service and make the case for more funding from the state by making the most of a new planning requirement from the legislature. As part of 2013’s landmark transportation finance legislation, the state legislature mandated that the RTAs conduct comprehensive service plans. This paper argues that if done well, these assessments could help make the case for more funding from the state going forward.
With bus rapid transit and light rail lines among the most expensiveinfrastructure projects undertaken by cities, funding is not taken lightly by local officials. The Transit Cooperative Research Program undertook a study to identify conditions and characteristics typically associated with successful fixed-guideway transit system investments and provide guidance on evaluating proposed investments based on these conditions and characteristics.
This report presents finding from research evaluating U.S. protected bicycle lanes (cycle tracks) in terms of their use, perception, benefits, and impacts. It finds that separated bike lanes both encourage new cyclists to ride and make motorists feel that cyclists were safer and more predictable.
While using standardized methodologies to measure the energy impacts and cost-effectiveness of efficiency programs is common practice in the electric and thermal energy sectors, this is not the case for transportation. National Association of State Energy Officials and Vermont Energy Investment Coprtation have developed the following Transportation technical reference manual to characterize energy savings, environmental benefits, and financial costs of selected transportation efficiency measures and establish a framework for comprehensive and informed decision-making.
This report from FHWA illustrates how sustainability has been incorporated into a wide variety of FHWA programs, projects, policies, processes, and partnerships. It is intended to be used by a diverse audience of transportation agency professionals at the Federal, State, and local level as well as the general public.
This report, issued by the George Washington University Business School, examines the growing preference for walkable urbanism and what that means for infrastructure, economic development, housing, etc. The authors rank the 30 largest metros on walkable urbanism, identifying a future demand for tens of millions of square feet of walkable urban development. This demand would provide an economic foundation for the U.S. economy, similar to the building of drivable suburbs in the mid to late 20th century.
This report presents finding from research evaluating U.S. protected bicycle lanes (cycle tracks) in terms of their use, perception, benefits, and impacts. Behavior of bicyclists, motorists, and pedestrians was assessed to determine how well each users understands the facility and to identify potential conflicts. Residents and bicyclists indicated that any type of buffer shows a considerable increase in self-reported comfort levels over a striped bike lane, and support for protected bike lanes was high among all users.
This report, the second in a series from FHWA, presents insights and a flexible model for state DOTs that choose to integrate public health considerations into their transportation planning and decision-making. It draws from five case studies of innovative DOTs and their partners, and builds on the project team’s previous white paper.
