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.

Review, Testing and Validation of Capacity and Delay Models at Unsignalized Intersections

Promet (Zagreb), 2007
This paper deals with problems related to the capacity anddelay models at unsignalized intersections. The parameters ofvarious models are calibrated based on the on-site data obtainedin the countries where the models were developed.

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 ...

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)

Journal 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

, 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.
