A nalysis and design of traffic control features for handling leftturn operations in at-grade intersections is one of the most problematic components of signalized intersection analyses. The Texas Section of ITE has embarked on an effort to provide improved left-turn analysis procedures through a section technical project. This article presents a summary of efforts and conclusions developed thr...

a 30-year-old woman presented with a palpable subcutaneous nodule in the areolar region of the left breast. sonomammographic examination revealed 2 cystic lesions showing typical “filarial dance” as vigorous twirling movement of multiple curvilinear echoes with mixed red blue color doppler signals that was non-rhythmic, nonpulsatile, and the characteristic pulse doppler trace due to irregular w...

A queue jumper lane is a special bus preferential treatment that combines a short stretch of a special lane with a transit signal priority (TSP) to allow buses to bypass waiting queues of traffic and then to cut out in front of the queue by getting an early green signal. This paper first proposes a signal control design for queue jumper lanes with actuated TSP strategies and then compares its p...

Abstract Left Turn Across Path with Opposite Direction (LTAP/OD) conflicts are one of the most common crash types at intersections. The research aims to reveal general and dynamic information about conflict for relevant street layouts each configuration LTAP/OD accidents involving passenger cars, motorcycles Ebikes. analysis was based on 276 collected by China In-Depth Accident Study (CIDAS 201...

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...

The first step in improving traffic safety is identifying hazardous situations. Based on traffic accidents’ data, identifying hazardous situations in roads and the network is possible. However, in small areas such as intersections, especially in maneuvers resolution, identifying hazardous situations is impossible using accident’s data. In this paper, time-to-collision (TTC) as a traffic conflic...
