Abstract: The Mobile Millennium project provided a platform for aggregating traffic information across various sources, including infrastructure sensors, commercial data feeds, probe vehicles, and probe cell phones. The Networked Traveler project provided the California PATH instrumented research vehicle platform used to both deliver vehicle probe data back to the infrastructure and to generate Advanced Driver Assistance Systems (ADAS) alerts to the drivers of those vehicles. The main theme of this collaboration project was to demonstrate the potential to create Enhanced Probe Vehicles (EPVs) by merging vehicle CAN-bus data with the typical GPS data that is provided by normal probe vehicles. The first goal of this project was integrate the two systems, allowing the instrumented research vehicles to communicate with the Mobile Millennium traffic aggregation servers. The second goal was to enhance the data gathered and stored by the Mobile Millennium traffic aggregation server to include the enhanced information provided by the EPVs, specifically, to include hazard warning light activation events. The third and final goal of this project was to integrate the information provided by the EPVs to the traffic server into soft-safety alerts that could be provided to the drivers of the EPVs and demonstrate the prototype system. This report documents the systems that were built for the demonstration, and provides a short analysis of the system performance from data gathered through both a simulation and an on-the-road vehicle test
