Pandas routing machine

A pandas-centric interface to highly performant travel network analysis leveraging contraction hierarchies provided by code from the Open Source Routing Machine (OSRM). Hence, the pandas routing machine, pandarm. This package is a friendly fork of the pandana library, originally written by Fletcher Foti and UrbanSim Inc. Despite fantastic work by the original authors, maintaining open-source software is a great deal of work and the pandana library is no longer compatible with the current pydata stack (specifically as of numpy version 2.0). This fork reinstates compatibility and brings along a few new modern touches and enhancements. Pull requests are very welcome. Main features of the package include: - multi-threaded calculation of shortest path routes and distances - network aggregations (i.e. accessibility metrics) - network-based isochrones
