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...

Sirisha Kothuri , Nathan McNeil
BACKGROUND
One of the most common locations for fatal motor vehicle-bicyclist crashes is at intersections, which inherently have a large number of turning conflicts. Reducing these conflicts is a key objective in improving intersection safety across all modes. Of particular concern for bicyclists’ safety at intersections are the conflicts between straight-through bicyclists and motor vehicle right-turns and opposing left-turns. Despite the widespread acknowledgement of this problem, trans...
