Two variations of demand reduction are commonly cited; one being access rate, the other diversion. Some metered ramps have bypass lanes for high-occupancy vehicles, allowing carpoolers, buses, and other eligible vehicles to skip the queue and get directly on the highway. US DOT Home | FHWA Home | Operations Home | Privacy, United States Department of Transportation - Federal Highway Administration. Fewer meters are activated during the course of a normal day than prior to the 2000 study, some meters have been removed, timing has been altered so that no driver waits more than four minutes in ramp queue, and vehicles are not allowed to back up onto city streets. Cars driving on the on-ramp to enter the freeway stop at the red light. Detectors (generally an induction loop) are installed in the road, both on the ramp and on the main road which measure and calculate the traffic flow, speed and occupancy levels. System-wide control is a form of traffic responsive control but operates on the basis of total freeway conditions. Am I allowed to proceed without stopping? When the signal turns green, one car per lane may leave the ramp and merge safely onto the freeway. Several new ramp meters have been implemented and activated throughout Spokane at on-ramps to both east and westbound I-90 with more coming.
