Session Title
Basic Traffic Operation: Left-Turn Warrant at Existing Signalized Intersections
Track Title
Traffic Operations
Event Description/Abstract
Existing left-turn lane warrants are based on the use of either turning volume or measured turning vehicle delay. This approach fails to account for passive demand— that is, vehicles that would prefer to make a left turn but instead take a circuitous path to make an easier turn. This presentation and the associated research discusses a gap-based alternative to instead find the availability of turning opportunities as a surrogate to actual turning vehicle delay.
