How do Ramp Management Strategies Improve Safety?
The manner in which safety is improved depends on the type of ramp management strategy selected. Ramp metering improves safety by breaking up platoons of vehicles entering the freeway, thereby allowing more orderly and safe interactions between merging vehicles and freeway mainline vehicles. Ramp closure improves safety by preventing vehicles from using ramps, where nearby events or activities pose a safety threat to vehicles. Other strategies improve safety by alerting motorists of conditions that motorists do not expect, while others reduce conflicts between through traffic and vehicles that intend to use the ramp.
