Abstract
This research proposes a framework for assessing the impacts of new and existing cycling facilities using minimum cycling impedance routing. Cycling impedance represents the relative difficulty of cycling and considers travel time, exposure to automobiles, hills, and the provision of cycling infrastructure. With map-matched cycling GPS traces from CycleAtlanta, this research calibrates cycling impedance functions using particle swarm optimization. The calibrated impedance functions are applied to a 250-square-mile Metro Atlanta study area network to assess the impact of 117 planned bicycle facilities on 3.6 million trips from the Atlanta Regional Commission Activity-Based Model. Five metrics, trip impedance reduction, percent detour, change in link betweenness centrality, impedance reduction contribution, and bikesheds highlight the impedance reduction impacts of new cycling infrastructure. Planners, engineers, and advocacy groups can utilize the framework to evaluate proposed cycling infrastructure and prioritize projects that stand to reduce the most cycling impedance. As new cycling trace data and network data become available, researchers can update the impedance functions to reflect the behavior of current cyclists and develop new impedance factors.
