Offsetting 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 ...
متن کاملAnalysis of Operation and Safety Characteristicsof Lefi-Turn Lanes
Left-turn lanes at nonsignaiized intersections on two-lane interurban roads reduce the number of traffic interferences and increase the level of service for the through traffic. These improved conditions result from the opportunity turning vehicles have to decelerate and wait in a separate lane for a suitable crossing gap. Decreasing the number of interferences to through traffic reduces the nu...
متن کاملPareto Improvements from Lexus Lanes
This paper shows that a judiciously designed toll applied to a portion of the lanes of a highway can be a Pareto improvement even before the revenue is spent. I achieve this new result by extending a standard dynamic congestion model to reflect an important additional traffic externality which transportation engineers have recently identified: additional traffic does not simply increase travel ...
متن کاملEvaluation of left-turn lane offset using the naturalistic driving study data.
INTRODUCTION The Strategic Highway Research Program 2 (SHRP 2) Naturalistic Driving Study (NDS) data were used to evaluate gap acceptance behavior of drivers at left-turn lanes with negative, zero, or positive offsets ranging from -29 ft to +6 ft. The objectives of the study were to develop guidance for the design of offset left-turn lanes used as a safety countermeasure, and to provide insight...
متن کاملSafety Benefits of Converting HOV Lanes to HOT Lanes: Case Study of the I-394 MnPASS
Recently, the conversion of HOV lanes to HOT lanes has been increasingly popular in the United States. Several empirical studies have explored the benefits and costs associated with the conversion. However, few quantitative studies have been performed to examine the impact of HOV-to-HOT conversion on traffic safety. Introduction With the hope of relieving highway congestion and generating reven...
