r5r is an R package that provides a simple and friendly interface to the Conveyal R5 routing engine for multimodal transport analysis. It enables R users to perform rapid, realistic routing calculations, generate travel time matrices, and compute accessibility metrics using seamless parallel computing, all within a familiar R environment. ## Key Features - **Multimodal Routing** — Calculates travel times and routes combining walking, biking, public transport, and car modes. - **Accessibility Analysis** — Fast computation of access to opportunities using various decay functions (step, logistic, exponential, linear). - **Detailed Itineraries** — Returns alternative routes with segment-by-segment details on mode, time, and walk distance. - **Travel Time Matrices** — Generates origin-destination travel time matrices considering departure or arrival times. - **Pareto Frontier Analysis** — Evaluates trade-offs between travel time and monetary cost for route alternatives. - **Isochrone Mapping** — Creates polygons showing reachable areas from an origin within a time limit. - **Monetary Cost Integration** — Accounts for fares and other costs in routing and accessibility calculations. ## Philosophy r5r aims to make advanced, high-performance multimodal transport routing accessible and easy to use for R practitioners, bridging the gap between robust routing engines and the R ecosystem for transport planning and research.
