In Tysons Corner, Virginia optimized signal timing reduced delay by approximately 22 percent and decreased stops by roughly 6 percent.
In May 1999, optimization of signal timing at 40 intersections was completed in the Tysons Corner area of Virginia. Estimates indicated the system reduced vehicle stops by approximately six percent and decreased delay by approximately 22 percent.
