1, 186 high-resolution vehicle trajectories were collected at four typical high-speed intersection approaches in Shanghai and used for the identification of actual stop-go decision zones and the modeling of stop-go decision behavior.
The yellow light dilemma zone is widely known as an area on the high-speed intersection approach, where vehicles neither safely stop before the stop line nor proceed through the intersection during amber interval.
The findings of this study could contribute the development of effective dilemma zone protection strategies, the improvement of stop-go decision model embedded in the microscopic traffic simulation software and the proper design of signal change and clearance intervals at high-speed intersections in China.
The objective of this study is to empirically analyze and model the stop-go decision behavior of drivers at rural high-speed intersections in China, where a flashing green signal of 3 s followed by a yellow signal of 3 s is commonly applied to end a green phase.
eIMPACT estimates that speed at intersections will increase by 1%, leading to an increase in fatalities and injuries at intersections by 2%.
For a long time, the design speed at intersections has been used to determine the physical radius of curbs and channelization, and drivers are expected to drive in accordance with the design speed.
In fact, on the very day the three new subway stops open, the Metropolitan Transportation Authority will introduce the next big proposal: 80 express buses outfitted with transponders that signal wire loops in the pavement to hold green lights (or shorten red ones) so buses can speed through intersections.
It was found that the marking can reduce the probabilities of both conservative-stop and risky-go decisions, contribute to a lower red-light running rate, and result in a lower deceleration rate for stopping drivers at higher speed limit intersections.
You see, when I watch impatient people drive through stop signs in their cars, or ride their bikes on the sidewalk or speed through intersections, I think about Wilson.
Seven main topics were more particularly investigated, recovering at last all the main dimensions of the driving task (from navigation to speed control, through intersection crossing).
The major road driver behavior was evaluated with reference to three variables: response time before possible conflict (RTPC), average speed while approaching intersection and at the intersection, and deceleration rate.
