SIGNALS

The emphasis on improving signal coordination for this countermeasure is to provide an opportunity for slow-speed signal coordination . Coordinating signals to allow for bicyclist progression , also known as a ‘ green wave ,’ gives bicyclists and pedestrians more time to cross through the ‘ green wave ’ intersections . It also slows vehicle speeds , helping to reduce the likelihood of severe collisions .

SIGNALS

At certain hours ( e . g . late night ) a signal remains red for all approaches or certain approaches until a vehicle arrives at the intersection . If the vehicle is going faster than the desired speed , the signal will not turn green until after vehicle stops . If the vehicle is going the desired speed the signal will change to green before the vehicle arrives . This signal timing provides operational benefit to drivers traveling at the desired speed limit . Can be paired with variable speed warning signs .
