![]() Lewis said another such project is planned for the 680 Freeway in Contra Costa County. Colorado officials are experimenting with the concept on Interstate 25 in Denver. The “smart freeway” concept is something that has been widely deployed in Australia with a measure of success, boosting traffic flow and reducing accidents, Standiford said. Similarly, the county transportation commission last month started adjusting toll prices on the new 15 Express Lanes according to real-time traffic conditions. It’s different on weekends.”Īnd, Barth said, a crash can happen at any time, throwing the system out of balance. “And it’s not going to be the same day to day as well. “The traffic demand fluctuates tremendously throughout the day,” Ma said. Making adjustments in real time is crucial, said Jiaqi Ma, associate director of the UCLA Institute of Transportation Studies. “They’re used quite a bit on our more impacted freeways, like the 91, 60 and the 10,” said Matt Barth, director of UC Riverside’s Center for Environmental Research and Technology.īarth said there is a significant difference, though: the ramp signals in Temecula will be able to adjust in real time based on conditions at a particular moment, instead of functioning according to a predetermined schedule. ![]() The project is similar to traffic management strategies across the Inland Empire that, for years, have relied on ramp meters. Ken Calvert, R-Corona, worked to ensure that the package included $5 million for the “smart freeway” system. The last piece of required funding for the $18 million Riverside County project was secured in March with Congress’ passage and President Biden’s signing of a federal spending bill. “What we’re doing here in Temecula is a first step in an area that could benefit from it,” Standiford said.Ĭaltrans spokesperson Terri Kasinga said there is a ramp meter already at Temecula Parkway - which will be upgraded - but not at the other two places. We'll send you the top local news stories every morning at 8 a.m.The commission and Caltrans plan to monitor the experimental project two years, then decide whether to continue it - and possibly expand the project to other places in Riverside County, a news release states. The I-15 Express Lanes exist between State Route 78 in Escondido and State Route 163 in San Diego. With input from I-15 commuters that participated in focus groups and surveys, upgraded signs were designed to address these issues, SANDAG said in a statement released Thursday. ![]() Recent research found that existing signage on the I-15 Express Lanes can be difficult to read, and that posted information about toll rates and who can use the lanes isn’t easily understood, according to the San Diego Association of Governments. New signs are being installed along Interstate 15 Express Lanes this week that are designed to provide easy-to-read information about toll roads rates and usage. Additionally, the diamond HOV symbol will be replaced on most signs with “HOV 2+ Free” to help clarify that high occupancy vehicles can use the Express Lanes for free. Instead of displaying the minimum toll rate, the new signs will list current toll rates and estimated travel times to upcoming freeway connectors.
