Intelligent Transportation Systems (ITS) apply advanced technology to improve transportation safety, efficiency, and sustainability. ITS includes traffic signal coordination that adjusts timing based on real-time conditions, electronic message signs alerting drivers to delays, automatic vehicle location systems for transit, and apps providing real-time transit arrival information. Municipalities use ITS to reduce congestion, improve emergency response times, enhance transit service, and gather data for transportation planning. As technology advances, ITS increasingly includes connected and autonomous vehicle systems, though implementation requires significant investment and ongoing maintenance.
