By managing queues of vehicles, ramp meters provide for safer merging of vehicles and mitigate potential collisions.

Phase 2 followed and as of March 2011 there are 88 Ramp Metering sites[11] on the 4,500 miles (7,242 km) of strategic highways operated and maintained by the HA.

2023 ADOT- This is a Free Drupal Theme, Law Enforcement Resources/AZCrash Report/Training Resources, Transportation Systems Management and Operations, By managing queues of vehicles, ramp meters provide for safer merging of vehicles and mitigate potential collisions.

Ramp metering was first implemented in 1963 on the Eisenhower Expressway (Interstate 290) in Chicago by Adolf D. May, now a UC Berkeley professor. Ramp meters are claimed to reduce congestion (increase speed and volume) on freeways by reducing demand and by breaking up platoons of cars. WebView up-to-date travel conditions including travel alerts, cameras, route times, road and bridge restriction, and weather alerts.

The ramp meters will also keep I-90 mainline at highway speeds.

Ramp meters typically operate by allowing one car to proceed per green light.

The HERO system takes real time data every 20 seconds from the motorway, ramps and arterial road in order determine the best signal timing for the next 20 seconds. It is illegal to run a red light on a ramp meter, just as it is against the law to run any red light.



The most straightforward ramp meter systems operate on a fixed metering rate, providing a pre-set interval between green signals. It also shows the ramp meter control for each area that has ramp metering, listed as either local or fixed-time control, or system control.
