Active Transportation Network Benefits Estimator | NCHRP Research Report 1149, Estimating Benefits of Closing Gaps in Active Transportation Networks: A Guide
Sarah Melling
Joe Broach
The Active Transportation Network Benefits Estimator was developed to support state and local DOTs in estimating the potential benefits of closing gaps in their active transportation network. The tool is based on the methodology presented in the NCHRP Research report 1149: Estimating Benefits of Closing Gaps in Active Transportation Networks (https://www.nationalacademies.org/publications/29332). Active transportation networks are an important part of the transportation system, they improve a...
