Many Department of Transportation agencies are looking for cost-saving ways to improve the efficiencies of roadways without making actual surface improvements or roadway expansions. Wireless-IP-enabled traffic signal control can be used to improve traffic flow and enable new applications for higher efficiency and cost savings. Advanced Transportation Management Systems (ATMSs) provide the ability to connect signal controllers to an intelligent network for enhanced data gathering and analysis and better timing of traffic signals. Connecting signal controllers to an intelligent network with a standards-based wireless IP infrastructure is cost-effective, provides flexibility in design, enables faster deployment, and provides a network infrastructure for future additional applications.
