Intelligent Transportation Systems (ITS) are technologies that create more efficient, safe and mobile roadway travel. Examples of ITS systems include digital freeway message signs (to display current travel times and allow drivers to make the best decisions for their commutes), ramp meters (to maintain steady traffic flow and enhance freeway mobility and safety) and traffic flow detectors and closed-circuit television systems (to help traffic operators address traffic conditions such as freeway congestion). Currently, NDOT has two major ITS projects underway in southern Nevada:
I-15 South ITS Design-Build Project
An approximately $13.5 million project to install intelligent transportation systems on Interstate 15 from the I-15/I-515 junction in southern Las Vegas to the Nevada/California state line.
Project began in September 2011 and is expected to complete in February 2013.
Project Components
Dynamic Message Signs/Travel Time Signs: Overhead freeway message signs to provide important driving information to motorists
Highway Advisory Radio: Localized radio broadcasts to provide local and immediate traffic and safety information to motorists
Ramp Meters: Traffic signal meters on freeway on-ramp to maintain steady traffic flow onto the freeway, reduce freeway congestion and enhance safety at the northbound I-15 on-ramp from Silverado Ranch Boulevard
Traffic Flow Detectors: Traffic flow detectors spaced from 1,800 to 4,000 feet apart to help report current traffic conditions to the public
Closed-Circuit Television: Closed-circuit cameras spaced from one to five miles apart to help emergency responders and traffic operators visually verify and immediately respond to crashes, incidents and traffic congestion
CC-215/I-515 to Railroad Pass ITS Project
An approximately $6.6 million project to install intelligent transportation systems from the CC-215/I-215 Interchange in Henderson to Railroad Pass in Boulder City.
Project began in April 2012 and is expected to complete in April 2013.
Project Components
Dynamic Message Signs/Travel Time Signs: Overhead freeway message signs to provide important driving information to motorists
Highway Advisory Radio: Localized radio broadcasts to provide local and immediate traffic and safety information to motorists
Ramp Meters: Traffic signal meters on freeway on-ramp to maintain steady traffic flow onto the freeway, reduce freeway congestion and enhance safety on the northbound Horizon Ridge on-ramp
Traffic Flow Detectors: Traffic flow detectors spaced from 1,800 to 4,000 feet apart to help report current traffic conditions to the public
Closed-Circuit Television: Closed-circuit cameras spaced from one to five miles apart to help emergency responders and traffic operators visually verify and immediately respond to crashes, incidents and traffic congestion
Project Benefits
Enhanced and accurate driving information for drivers
Increased efficiency and traffic flow
Reduced travel times
Improved reaction to and management of traffic incidents
Enhanced safety in the corridor
