What does reducing delays at intersections primarily achieve?

Reducing delays at intersections primarily enhances overall traffic flow. When delays are minimized, vehicles can move more efficiently through intersections, which leads to smoother and more continuous traffic movement. This improvement in traffic flow can decrease the time vehicles spend idling or stopped, which in turn reduces congestion. Streamlined traffic conditions also contribute to reduced travel times for all road users.

While improved fuel efficiency for vehicles can be an indirect benefit of reduced delays, the main goal is to facilitate better movement of traffic. Increased pedestrian activity may occur due to enhanced safety and accessibility brought about by better traffic flow, but it is not the primary outcome of reducing delays. Additionally, reducing delays is typically associated with lower accident rates, as vehicles are moving more predictably and consistently through intersections. However, the key direct achievement from reducing delays remains the enhancement of overall traffic flow.
