The purpose of metering is to prevent congestion. It is done by traffic signals limiting the flow to 90% of capacity. Then a green wave can be managed between successive intersections. Ideally this green wave is a platoon that moves at the speed limit, in a compact bunch without dispersing, and with a minimum of acceleration and braking. The time gap between the traffic platoons will be relatively clear of traffic, allowing easier access to side streets and properties.

Convert traffic congestion on arterial streets to free flow using existing infrastructure, and get fast trips and low emissions

Proper operation of arterial streets will produce a green wave, where a platoon of traffic flows through sequential sets of traffic signals at the speed limit with the minimum of wasted time, braking, acceleration, and emissions. The following steps are employed as necessary:
