Abstract
Transportation systems require reliable and accurate data for monitoring and managing operations that maximize the safety and efficiency of the roadway network. The proliferation of connected (or cooperative) and automated vehicles, which are capable of providing data regarding vehicle speeds and volumes, congestion and collision avoidance maneuvers, and inclement weather and other potentially dangerous road conditions, create both a major opportunity and a major challenge for public agencies and private companies that support intelligent transportation systems (ITS). The opportunity arises from the diversity of data available to traffic and transportation management personnel, while the challenge arises from the need to gather, process, analyze, and store the vast quantities of data that will flow to the traffic management agencies, especially as big data become available. These emerging and fertile data sources, along with the spread of Bluetooth® and IP-based (cellular and Wi-Fi) communications technologies, will increase the travelers’ proclivity for accurate road traffic information.
