Streets make up more than 80 percent of public space in cities and towns. From one edge of the right-of-way to the other, planners, engineers, and community groups are coming together to decide how they want to allocate this precious resource.

The TRB National Cooperative Highway Research Program’s pre-publication draft of NCHRP Research Report 1036: Roadway Cross-Section Reallocation: A Guide describes how street design decisions impact communities and clarifies how different street elements influence not just transportation outcomes, but livability, economic and environmental health, equity, and many other concerns.
