Cedar Park, Texas is consistently ranked one of the fastest-growing cities in the country, causing traffic volume to exceed capacity at two intersecting high-volume, high-speed corridors. The intersection serves two important regional arterials with major retailers where local residents and visitors from neighboring communities come to shop, dine, and work. Growing traffic volume resulted in gridlock, potential for illegal turns, violations of right-of-way assignments, and greater risk of dark signals at the intersection.
In partnership with the Texas Department of Transportation (TxDOT), Cedar Park decided to convert the intersection to a Continuous Flow Intersection (CFI). Due to the complex nature of the CFI’s operation, unfamiliarity to new drivers, and high traffic volumes, it was critical that the intersection never go dark no matter the length of a power outage.
