- 요약The lack of cycling infrastructure is a major deterrent to the use of bicycle transportation in the United States. Planners and engineers currently lack a comprehensive set of tools that can be used to assess and communicate how new and improved cycling infrastructure would potentially improve cycling mobility and accessibility. Without these tools, cycling infrastructure may be built ad hoc or where it is politically convenient, instead of where it would be the most effective, thus reducing the likelihood that bicycles will be used for transportation. This research outlines a framework for assessing new and existing cycling infrastructure through minimum impedance routing, which is calibrated through stochastic optimization techniques on a dataset of monitored cycling GPS traces. Impedance represents the relative difficulty of cycling along different routes, taking into consideration travel time, road grade, exposure to traffic, turn movements, characteristics of cycling infrastructure provided, etc.The framework is implemented by first developing an all-paths network (containing all viable streets and non-motorized paths for cycling) from OpenStreetMap data. Then, data on traffic volumes, vehicle speeds, the number of vehicle lanes, elevation, and bicycle facilities are joined to the all-paths network. Once joined, links where cycling is not viable (Interstates, Interstate access ramps, sidewalks, parking aisles, driveways, etc.) are removed. In the case of sidewalks, it should be acknowledged that cyclists do often ride on sidewalks if they find it uncomfortable to ride on the adjacent road (Barajas, 2021; Chaloux & El-Geneidy, 2019; Marshall et al., 2017). However, sidewalks were infeasible to include for the analyses of this dissertation because the GPS data are not precise enough to determine if a cyclist was on the road or the sidewalk. In the research study area, the all-paths network consisted of over 77,000 links, 66,000 nodes, and 223,000 link-to-link turn opportunities.Processed and filtered cycling GPS traces from the CycleAtlanta app were map matched to the all-paths network. More than 2,500 trips, across more than 600 users, were successfully map matched to the all-paths network. These data were used to calibrate impedance factors for minimum impedance routing. The impedance calibration process uses particle swarm optimization to maximize the similarity between the map-matched and modeled impedance routes. The best-performing combination of impedance factors included attributes for the number of lanes, the speed limit, the average link grade, cycling facility type (if any), turning movements, and turn characteristics. As additional network data becomes available, additional impedance factors can be calibrated. The bootstrap method was used to estimate confidence intervals for the coefficients and objective function. This allowed for the statistical hypothesis testing against the travel time model. Using the bootstrap estimated median coefficient values, the bootstrap impedance model showed a 30% increase in the overlap metric from the least travel time model.The calibrated link and turn impedance functions reported herein were then applied to the 250 square mile metro Atlanta study area to assess the impact of 117 planned bicycle facilities for 127,682 unique origin-destination pairs (representing 3.6 million trips across from the Atlanta Regional Commission Activity Based Model TIP Amendment Six 2030 model run). The minimum travel time and minimum impedance routes were calculated for the existing network and compared against the minimum impedance routes for the future network that contained the planned bicycle facilities. The results were then processed to create metrics and visuals on trip impedance reduction, percent detour, change in link betweenness centrality, impedance reduction contribution, and bikesheds.The open source BikewaySim repository contains scripts for creating an all-paths network from OpenStreetMap data, reconciling other data sources with the all-paths network, map matching cycling GPS traces, calibrating link and turn impedance functions, and using the framework to evaluate new and improved cycling infrastructure.
