Safety Performance Evaluation of a Three-Leg Unsignalized Intersection Using Traffic Conflict Analysis [PDF]

open access: yes, 2017
Traffic conflicts were used to evaluate safety performance of a three-leg unsignalized intersection. With the aid of a video camera, data were collected at the intersection and 15-second time span was used in each observation to overcome the drawbacks of

Optimization of delay at intersection in anticipate stuck on the traffic by using software SIDRA intersection 8.0 (Case study : BPKP’s intersection at Banda Aceh)

open access: yesJournal of Civil Engineering
BPKP’s Intersection at Banda Aceh is one of the signalized intersections with four approaches. So there are 16 crossings, 8 diverging, and 8 merging, between vehicles such as delay and congestion.

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

open access: yes, 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.

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

open access: yesJournal 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

Analyzing angle crashes at unsignalized intersections using machine learning techniques

open access: yes, 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.
