No more sites were developed for the next two decades until a second 'pilot' study in 2006 by the Highways Agency (HA) concluded that ramp metering provides a net benefit under certain conditions - generally more congested junctions. Simulation results from one study showed that, during an incident, coordination of arterial traffic signals and ramp meters can improve the traffic performance of a corridor. A look at a Phoenix-area ramp meter in action. Now the cars are traveling at speed and once one car attempts to stop for the red light, it could set up the possibility for a crash. (Kevork Djansezian/Getty Images). Ramp metering was then introduced widely in England - Phase 1 involved the implementation of approximately 30 sites and was completed by 2008. Thats why our ramp meters rest in red, and not in green. Columbus police on scene of bank robbery at Wells Fargo on Milgen Rd.
