Statistical Analysis of Bicyclists’ Injury Severity at Unsignalized Intersections

Traffic Injury Prevention, 2015
This study investigated factors correlated with the severity of injuries sustained by bicyclists in bicycle-motor vehicle crashes at unsignalized intersections to develop site-specific countermeasures and interventions to improve bicycle safety.Crash data were extracted from accident reports entered into the Kentucky State Police's Kentucky Collision ...

Analyzing angle crashes at unsignalized intersections using machine learning techniques

Accident Analysis and Prevention, 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.

Analysis of traffic conflicts with right-turning vehicles at unsignalized intersections in suburban areas

International Journal of Transportation Science and Technology, 2023
Right-turn collisions at intersections are one of the most dominant crash types in suburban areas, especially at unsignalized intersections. There is, however, a lack of comprehensive research on the speed patterns of vehicles during right-turn ...

Unsignalized Intersection Level of Service: A Bicyclist’s Perspective

International Journal of Intelligent Transportation Systems Research, 2021
As the traffic conditions at unsignalized intersections are complex and chaotic, the perceived satisfaction levels of bicyclists are controlled by several factors. Although complex, the Bicycle Level of Service (BLOS) studies at this facility are highly important so as to improve its performance from the perspective of bicycling.

Estimation of left-turn capacity at the unsignalized intersection

Simulation Modelling Practice and Theory, 2021
Abstract The capacity of unsignalized intersections is a significant value that indicates traffic conditions as well as network performance at urban and rural roads. These intersections are the most numerous on the road network. Inaccurate determination of unsignalized intersections capacity can give a misconception of the traffic conditions on the ...

Unsignalized Intersections

2020
This chapter deals with unsignalized intersections and methods for determining the measures of effectiveness (MOE): waiting times and delays. To this regard, the TRL method for estimating capacity, queues, delays at three-arm intersections is exemplified.

Queueing at unsignalized intersections

Transportation Research Part B: Methodological, 1997
Abstract A general queueing theory model for traffic flow at unsignalized intersections is described and analysed which contains most of the mathematical models developed in the literature as special cases. Thus a consistent approach is presented for obtaining these models from a general viewpoint.

Unsignalized Intersections: Roundabouts

2020
Europe has made extensive use of roundabouts for many decades, and traffic circles, often around significant monuments, have been around for centuries. While some traffic circles and roundabouts have always existed in the U.S., interest in their ability to reduce delays (compared to signalized intersections) and create safer and more efficient flow ...

Safe spacing of unsignalized intersections on arterial roads

2009 IEEE/INFORMS International Conference on Service Operations, Logistics and Informatics, 2009
It is well known that limited safety distance and excessive intersections are the main reasons of the increasing traffic accidents on arterial roads. Based on the highway functional classification and intersection control types, the intersection spacing mode is divided firstly to make sure the arterial road access spacing and intersection corner ...

Modeling aggressive driver behavior at unsignalized intersections

Accident Analysis & Prevention, 2007
The processing of vehicles at unsignalized intersections is a complex and highly interactive process, whereby each driver makes individual decisions about when, where, and how to complete the required maneuver, subject to his perceptions of distances, velocities, and own car's performance.
