The Open Source Application Development Portal Adds More Intelligent Transportation System (ITS) Applications for Download

The Open Source Application Development Portal (OSADP) is a web-based portal that provides access to and supports the collaboration, development, and use of open-source ITS-related applications. The OSADP has added a number of new ITS-related applications that are available free to the public.

The following new applications are now available for download:

  • Dynamic Intermodal Routing Environment for Control and Telematics - Analysis, Modeling and Simulation (DIRECTView-AMS) is a visualization application designed to visualize the performance measures generated during simulations using DIRECT software with options to turn on and off scenarios. This tool can be used for evaluating dynamic mobility applications and active transportation and demand management strategies, applications, and concepts.
  • Intelligent Network Flow Optimization Analysis, Modeling, and Simulation (AMS) consists of three different applications used in the San Mateo, California, AMS test bed effort—queue warning, speed harmonization, and cooperative adaptive cruise control. These cross-functional applications were modeled together and used simulation inputs (sensor and connected vehicle data) to generate vehicle-specific commands and desired speed decisions.
  • Connected and Automated Speed Harmonization software analyzes real-time traffic conditions to calculate and communicate speed commands for connected and automated vehicles (CAVs), with the overall goal of harmonizing traffic flow. This application includes software to run on a server that simulates a traffic management center (TMC) to collect the data needed to perform a speed control algorithm and communicate results with CAVs; on-board speed control software for CAVs to enable two-way communication with the TMC; and an on-board Human Machine Interface to display information on current speed, commanded speed, confidence in the commanded speed, and the status of surrounding CAVs to the CAV driver.

The U.S. Department of Transportation’s Intelligent Transportation Systems Joint Program Office (ITS JPO) funds the OSADP to help facilitate the advancement of research, development, planning, testing, and deployment of connected vehicle and traveler-related applications and ITS. The OSADP features source code, software, applications, and resources (e.g., documentation, licenses, data) to support the use or further development of these ITS-related applications.

Public agencies, service providers, researchers, application developers, and others are invited to visit the OSADP at
