Evaluation of intersection conflict warning system at unsignalized intersections: A review

Journal of Traffic and Transportation Engineering (English ed. Online), 2023
Unsignalized intersections are identified as the critical locations due to higher number of road crashes at these locations. The primary causes of crashes at unsignalized intersections are limited sight distance, incorrect assessment of gaps by drivers ...

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 ...

Transport delay assessment at unsignalized intersections feeding focal points [PDF]

MATEC Web of Conferences, 2021
The article discusses the issues of assessing the delays connected with the transport service of people visiting focal points (FPs) by individual transport (IT). The necessity of using a mathematical approach when assessing delays is proved.

Approach to Determine Transport Delays at Unsignalized Intersections

Communications, 2023
This study proposes an approach to determine transport delays at unsignalized intersections, according to the theory of stationary Poisson flow and considering the priority of vehicle traffic in competing directions. The accuracy of the proposed approach

Examining the effect of vehicle type on right-turn crossing conflicts of minor road traffic at unsignalized T-intersections

IATSS Research, 2023
In India, the crossing conflicts between right-turn vehicles of minor road traffic and conflicting vehicles on major roads have become more severe at unsignalized T-intersections in recent times.

Modeling cooperation in unsignalized intersections

Procedia Computer Science, 2017
Abstract: The Nordic countries, among others, rely heavily on unsignalized intersections, even in congested conditions. When unsignalized intersections are blocked due to queue spillbacks from downstream bottlenecks, the intersections do not function as intended. Traditional gap acceptance models do not provide realistic results under such conditions.

Development of a conflict-free unsignalized intersection organization method for multiple connected and autonomous vehicles. [PDF]

PLoS ONE, 2021
An effective traffic control strategy will improve travel reliability in urban transportation networks. Lack of coordination between vehicles, however, exacerbates congestion due mainly to frequent stops at unsignalized intersections. It is beneficial to

Unsignalized intersection vehicle platoon formation scheduling method based on mixed traffic [PDF]

Scientific Reports
Managing unsignalized intersections is further developed in the context of automated driving with vehicle-road coordination. In this context, the virtual platoon of lining vehicles into a one-dimensional virtual queue is based on a fully automated ...

Assessment of cyclists yielding to pedestrians at an unsignalized zebra crossing in Germany using drone video [PDF]

Scientific Reports
Previous research has examined vehicle-pedestrian and vehicle-cyclist interactions, but there have been few studies that examined cyclist-pedestrian interactions at intersections. This study addresses this gap by analyzing cyclist-pedestrian interactions
