The Puerto Rico Highways and Transportation Authority has a center that performs remote monitoring and control functions for traffic signal systems. Currently, the system is fully operational for 19 traffic signal systems on the PR-2 highway from Hormigueros to Mayagüez. In the near future, more traffic signal systems will be added expanding this functionality to more than 50 traffic signals, including the expansion of PR-2 coverage from Hatillo to Mayagüez, in San Juan, Ponce de León, Fernández Juncos, Muñoz Rivera and F.D. Roosevelt Avenues, among others.
This system provides continuous communication and monitoring for the coordinated operation of the traffic lights connected through this system. The system uses a series of sensors and video detector controllers to collect and analyze data from traffic traveling through an intersection to optimize its operation. This data is also stored for future analysis and to modify traffic signal timing plans in the future once it is determined that an overhaul is needed. This system also alerts operators in the event of component failures so that they can take corrective action to minimize the negative impacts these failures have on the transportation network.
