GTFS Analysis Tools > R5: Rapid Realistic Routing on Real-world and Reimagined networks
A Java-based routing engine developed by Conveyal for multimodal (transit/bike/walk/car) networks. It currently plans many trips over a time window for scenario planning and analytics purposes. A related R wrapper package (r5r) is developed independently by IPEA. See also the performance comparison from Higgins et al. (2022), linked below.
