LISA: Level of Intersection Stress Analysis
Washington, D.C., has been a national leader in the adoption of innovative bicycle facilities. However, with much of the low-hanging fruit already plucked (i.e., bicycle facilities already in place), the District Department of Transportation (DDOT) needs a mechanism to prioritize investments to improve bicyclist safety and accessibility. Thus, with the support of the Santos Family Foundation, project LISA aims to provide a mapping, using a model that takes into account key characteristics of road segments and intersections, that can be used to prioritize future bicycle infrastructure investments and be updated with additional data as it is collected and new facilities are constructed. LISA will help DDOT corroborate existing perceptions about the availability of bicycle facilities and identify gaps in the overall bicycle network. In addition, LISA will be used as a proof-of-concept for other jurisdictions as they look to develop their own bicycle network maps.
