Conventional four-legged intersections are inefficient under heavy traffic requirements and
are prone to congestion problems. Unconventional intersections with innovative designs …

Displaced left-turn (DLT) intersections that resolve the conflict between left-turn and
opposing-through movements at the pre-signal are probably the most extensively used …

The use of unconventional arterial intersection designs (UAIDs) has been advocated as a
novel solution that can efficiently enhance the operational and safety performance of at …

Several unconventional intersection designs have been proposed as an innovative
approach to mitigate congestion at heavily congested at‐grade signalized intersections …

Traffic engineers are making efforts to mitigate congestion and to improve efficiency at
intersections. The symmetric intersection (SI) can increase the capacity of intersections and …

The development of surrogate safety measures is essential due to the problems of
availability and quality of historical crash data. The Aggregate Conflict Propensity Metric …

The present study conducted an operational performance analysis of the contraflow left-turn
lane (CLL) design considering the influence of the upstream signalized intersection. The …

Heavy traffic volume coupled with insufficient capacity due to limited space cause most of
traffic congestion at urban signalized intersections. This article presents an innovative …

Displaced left-turn intersections (DLTs) are designed to enhance the operational
performance of conventional intersections that are congested due to heavy left-turn traffic …

It is well recognized that the left-turning movement reduces the intersection capacity
significantly, because exclusive left turn phases are needed to discharge left turn vehicles …
