RouteE API

This is the API endpoint for RouteE energy prediction, which can be used to get both single vehicle link or route energy estimates and transportation network-wide energy consumption estimates for a variety of vehicles. This enables external researchers and transportation engineers to access and utilize NREL's growing library of pre-trained vehicle models for prediction of transportation energy consumption. This API provides three endpoints: - /route: Energy estimation of a vehicle over a planning link or sequence of links (route). - /network: Network-wide estimation of energy consumption for all vehicle traffic in the desired area. - /compass: Energy-optimal “eco-routing” between input origin and destination coordinates (Currently in beta for Denver metro area only).

Mappymatch [SWR 22-38]

Mappymatch is a pure-python package developed and open sourced by the National Renewable Energy Laboratory. It contains a collection of "Matchers" that enable matching a GPS trace (series of GPS coordinates) to a map. As of 8/14/2023, The current matchers are: LCSSMatcher: A matcher that implements the LCSS algorithm described in this paper. Works best with high resolution GPS traces. OsrmMatcher: A light matcher that pings an OSRM server to request map matching results. See the official documentation for more info. ValhallaMatcher: A matcher to ping a Valhalla server for map matching results. Currently supported map formats are: Open Street Maps NOTE: This software was formerly known as YAMM (Yet Another Map-Matcher)
