Manage Traffic By Using Priority Management Systems

Traffic issues from commercial vehicles or automobiles are a common cause of turbulence on roads and highways across the globe. If not in order, it leads to an increasing number of accidents, fights, chaos, and even pollution.

Municipalities worldwide are looking to use advanced Priority Management Systems or active systems as it has the capabilities to control the growing population of connected cars now on the road. Complete data at junctions, roads, and other places are required to understand the market size and the traffic flow. Even with the historical data, the authorities can make sound predictions as the traffic data are considerable.

Transit Signal Priority (TSP) includes a set of operational developments using technology to decrease traffic signals' stay time for transit vehicles. It holds green lights longer or even less time for red lights.

Advantages & Capabilities of Traffic Priority Management Systems -

Traffic Priority Management Systems can lessen congestion on highways or roads by bringing together traffic flow sensors, data analysis, and communications technologies.

Capabilities include:

• Centralized traffic monitoring
• Public transportation information with presumed wait times for buses
• Manual/automated updates to traffic signals
• Incident/Event monitoring and emergency response
• Road Weather Information System (RWIS) monitoring
• Highway Advisory radio
• Manual/automated updates to ramp metering systems
• Predictive traffic modeling
• Predictive traffic modeling helps traffic engineers design improvements to road infrastructure post analyzing the data.

Traffic Signal Preemption is helpful as one can use it both at individual intersections or across corridors or entire street systems. 

Traffic Signal Priority system capabilities comprise of -

• Disturbance Monitoring
• Traffic Signal Timing,
• Automated Ramp Metering Systems,
• Variable Message Signs

Additional techniques include:

• Automated incident detection
• Dynamic junction control or dynamic lane access
• Dynamic merge control
• Dynamic shoulder lanes
• Dynamic speed limits
• Transit signal priority
• Rerouting capabilities

Connected car data offers several significant advantages for traffic management systems:

• More extensive scale
• New and richer datasets  
• Data de-identification
• Consumer approval 
• Lower capital expenditures and operating costs

Companies like EMTRAC Priority Management System use accurate navigation technology and secure RF communication to detect equipped transit, emergency, and municipal vehicles. The systems also come with advanced features that permit vehicles to inform current "en-route conditions" so traffic controllers can modify phase timing before allowing traffic signal priority.
