Live signage will be spread throughout the Neon project by the end of the year
Digital messages will flash from a dozen electronic signs by the end of the year, warning commuters to slow down as they approach the huge construction zone that will soon envelop the Spaghetti Bowl.
By September, crews will begin erecting the full-color signs that will soon provide real-time information about accidents, lane restrictions and detours along Interstate 15 and US Highway 95.
The new active traffic management signs are included in the $1 billion budget for Project Neon, the largest public works freeway project in Nevada history.
The largest marquees will be 12.5 feet high and 77 feet wide, making them much larger and “much more sophisticated” than existing signs that display travel times to freeway exits, said Nevada Department of Transportation officials on Monday.
The “smarter freeway” system has a system of sensors lining the freeway that will detect heavy traffic jams, car accidents, bad weather and other conditions that could impact traffic, a said Denise Inda, the agency’s chief traffic operations engineer, to the transit agency’s board.
This real-time information is immediately fed to digital signs that will lower the speed limit, with the aim of reducing accidents and stop-and-go conditions for the 300,000 vehicles that pass through the Spaghetti Bowl, the freeway interchange daily. the busiest in the state.
The information could be displayed on navigational tools and phone apps regularly used by commuters, but Governor Brian Sandoval warned that “everyone should trust what’s on the signs first”.
Another 40 electronic signs will be erected as far south as Silverado Ranch Boulevard on I-15 by the end of construction in July 2019 on Project Neon, which will redesign and add traffic lanes to the Spaghetti Bowl.
A groundbreaking event was held in April, followed by pre-construction work. Department of Transportation officials said traffic will be particularly difficult for eight months starting in March 2018, when construction crews are expected to build an 81-foot-high carpool lane spanning 2,606 feet that will connect the I-15 and US 95.
State officials said they hoped to see similar success to that reported on Interstate 5 in Seattle, where similar traffic-monitoring equipment led to a 14% drop in weekend crashes.
Other cities across the country have reported similar results with the technology, resulting in fewer commuter deaths, injuries and delays, agency spokesman Tony Illia said. The Spaghetti Bowl records an average of three accidents per day.
“The biggest benefit is the reduction in accidents, especially on weekends,” Illia said. “This is attributable to non-commuting drivers who may not be familiar with the area, which is particularly relevant in Las Vegas where large numbers of tourists use the I-15 corridor daily.”
