ALTRIOS (Advanced Locomotive Technology and Rail Infrastructure Optimization System) [SWR-22-54]

The Advanced Locomotive Technology and Rail Infrastructure Optimization System (ALTRIOS) is a unique, fully integrated, open-source software tool to evaluate strategies for deploying advanced locomotive technologies and associated infrastructure for cost-effective decarbonization. ALTRIOS simulates freight-demand driven train scheduling, mainline meet-pass planning, locomotive dynamics, train dynamics, energy conversion efficiencies, and energy storage dynamics of line-haul train operations. Because new locomotives represent a significant long-term capital investment and new technologies must be thoroughly demonstrated before deployment, this tool provides guidance on the risk/reward tradeoffs of different technology rollout strategies. An open, integrated simulation tool is invaluable for identifying future research needs and making decisions on technology development, routes, and train selection. ALTRIOS was developed as part of a collaborative effort by a team comprising the National Renewable Energy Laboratory (NREL), University of Illinois Urbana-Champaign (UIUC), Southwest Research Institute (SwRI), and BNSF Railway.

HIVE™ [SWR-19-36]

The HIVE™ platform is a mobility services simulation platform developed to provide insight on the energy, infrastructure, service, and economic outcomes of various mobility as a service (MaaS) options. The HIVE platform takes a set of spatiotemporal travel origin-destination pairs and simulates the operation of a predefined mobility service fleet, incorporating request pooling, and various operational and charging behaviors. Hive specializes at modeling fleets of automated electric vehicles (AEVs) and can be used to site and size direct current fast charge (DCFC) stations and measure grid impacts of large-scale AEV fleets serving real-world MaaS trip demand (similar to taxis, Uber, Lyft, etc.). Potential outcomes from a Hive simulation include level of service, total vehicle miles traveled (VMT), deadheading (zero passenger) miles, simultaneous and total energy loads, average occupancy, and more. Hive is developed to generalize to new regions and can be customized to handle many scenarios and operating conditions.

Mappymatch FKA: YAMM (Yet Another Map-Matcher) [SWR 22-38]

A surprisingly non-trivial technical challenge is to associate points in space (e.g., GPS data) with specific segments of a road network or map. The software package ( allows users to match GPS point data to a road network (commonly known as "map matching"). The software is designed such that a user could match a set of GPS points to a variety of different road network representations using a variety of map matching algorithms. There are currently several "built-in" road networks and map matching algorithms but the software has been designed to enable new ones to be added with minimal overhead.

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)
