Modeling 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 کاملDelay Variability at Signalized Intersections
Delays that individual vehicles may experience at a signalized intersection are usually subject to large variation due to randomness of traffic arrivals and interruption caused by traffic signal control. While such variation may have important implications for the planning, design and analysis of signal controls, currently there is no analytical model available to quantify it. This paper descri...
متن کاملPerception of Waiting Time at Signalized Intersections
Introduction Perceived waiting time (PWT) at signalized intersections differs from the real value of waiting time (WT), and varies with signal design. The onerousness of delay depends on the conditions under which it is experienced. Using weighted travel time may contribute to optimal signal control if its use can improve upon assuming that all time is weighted equally by users. This research e...
متن کاملAngle-accident Risk at Signalized Intersections
This paper demonstrates how a new modeling methodology can be applied to intersection angle-accident risk evaluation with data collected from 81 signalized intersections in the Tokyo Metropolitan area. Angle collisions between through traffic flow and opposite right-turn (please note that vehicles travel along the left side of the road in Japan) traffic flow are the second most common type at s...
متن کاملEvaluation of bike boxes at signalized intersections.
This paper presents a before-after study of bike boxes at 10 signalized intersections in Portland, Oregon. The bike boxes, also known as advanced stop lines or advanced stop boxes, were installed to increase visibility of cyclists and reduce conflicts between motor vehicles and cyclists, particularly in potential "right-hook" situations. Before and after video were analyzed for seven intersecti...
