Examining traffic crash injury severity at unsignalized intersections

Journal of Safety Research, 2010
This study presents multiple approaches to the analysis of crash injury severity at three- and four-legged unsignalized intersections in the state of Florida from 2003 until 2006. An extensive data collection process was conducted for this study.The dataset used in the analysis included 2,043 unsignalized intersections in six counties in the state of ...

Analysis of Unsignalized Intersection Performance on Jl. Dr Sutomo, Baturaja City [PDF]

An unsignalized intersection is the meeting point of several road approaches without traffic signal control. The vehicle control mechanism is implemented through traffic signs and priority rules. Problems arise when traffic volume increases.

How pedestrians actually jaywalk: fine-grained adaptive strategies revealed by roadside LiDAR

Transportation Research Interdisciplinary Perspectives
Jaywalking is widely studied as a compliance problem, yet what actually happens during the jaywalking process remains understudied. This study deploys roadside LiDAR at two urban intersections in Munich, Germany to decompose jaywalking into discrete ...

A cooperative control method for connected and automated vehicles at unsignalized intersection based on Monte-Carlo tree search

Journal of Traffic and Transportation Engineering (English ed. Online)
Enhancing the efficiency of traditional traffic light-based intersection control in intricate and dynamic traffic scenarios proves challenging due to vehicular queuing and frequent starts and stops. Addressing this challenge, a cooperative control method

Study of traffic flow at an unsignalized T-shaped intersection by cellular automata model

, 2005
In this paper, the traffic flow at an unsignalized T-shaped intersection in which there are three input directions of vehicles and two right-turnings and one left-turning has been investigated by using the cellular automata traffic model.

Advanced Decision Making and Motion Planning Framework for Autonomous Navigation in Unsignalized Intersections

IEEE Access
Autonomous vehicle navigation relies heavily on integrating sensor data, perception, path planning, localization, and vehicle control. However, existing research often treats these components in isolation, particularly at unsignalized intersections ...

Analyzing angle crashes at unsignalized intersections using machine learning techniques

, 2011
A recently developed machine learning technique, multivariate adaptive regression splines (MARS), is introduced in this study to predict vehicles\u27 angle crashes. MARS has a promising prediction power, and does not suffer from interpretation complexity.
