Developing an Analytical Model and Simulation of The Contraflow Left-Turn Lane at Signalized Intersections
At some intersections, excessive queue lengths may spill out of the left-turn bay and block the through lanes, jeopardizing level of service for the entire intersection. One of the most effective plans recently presented by the researchers is the "Contraflow left-turn lane" (CLL) In this method, left-turn vehicles will use the nearest lane in the opposite direction in addition to the usual left...
متن کاملSafety Effects of Protected Left-Turn Phasing at Signalized Intersections: An Empirical Analysis
Left-turn crashes occur frequently at signalized intersections and often lead to severe injuries. This problem can be addressed through the implementation of protected left-turn signals. This gives left-turning vehicles the right to enter the intersection free from conflict with opposing drivers and pedestrians. The present study analyses the effect of this measure on crash occurrence. The stud...
متن کاملIncreasing the Capacity of Signalized Intersections with Separate Left Turn
Separate turn phases are often used on the approach legs to intersections with heavy left turns. This wastes capacity on the approach because some of its lanes cannot discharge during its green phases. The paper shows that the problem can be eliminated by reorganizing traffic on all the lanes upstream of an intersection using a mid-block pre-signal. If drivers behave deterministically, the capa...
متن کاملModeling left-turn crash occurrence at signalized intersections by conflicting patterns.
In order to better understand the underlying crash mechanisms, left-turn crashes occurring at 197 four-legged signalized intersections over 6 years were classified into nine patterns based on vehicle maneuvers and then were assigned to intersection approaches. Crash frequency of each pattern was modeled at the approach level by mainly using Generalized Estimating Equations (GEE) with the Negati...
متن کاملOffsetting Opposing Left-Turn Lanes at Signalized Intersections: A Safety Assessment Case Study in Lincoln, Nebraska
Opposing left-turning vehicles at signalized intersections block each others’ view of oncoming traffic. The ability to see oncoming traffic is critical for safe negotiation of left-turns at intersections during a permitted left-turn phase of the signal. Offsetting of opposing left-turn lanes at signalized intersections improves sight distance for left-turning motorists. This paper reports on a ...
