Comprehensive Analytical Investigation Of The Safety Of Unsignalized Intersections

, 2009
According to documented statistics, intersections are among the most hazardous locations on roadway systems. Many studies have extensively analyzed safety of signalized intersections, but did not put their major focus on the most frequent type of ...

Microscopic analysis of traffic behavior at unsignalized intersections in developing world

, 2016
Unsignalized intersections in India are uncontrolled, and are characterized by chaotic traffic situation and have become accident hot spots. In this study, we have collected traffic data at three uncontrolled intersections, one each is from city center ...

Stochastic models for unsignalized road traffic intersections [PDF]

, 2019
In this thesis, we contribute to the modeling and analysis of unsignalized priority-controlled road traffic intersections, on which vehicles on a ‘major' road have priority over vehicles on a ‘minor' road. Our models for such intersections are stochastic

Toward edge-computing-enabled collision-free scheduling management for autonomous vehicles at unsignalized intersections

Digital Communications and Networks
With the support of Vehicle-to-Everything (V2X) technology and computing power networks, the existing intersection traffic order is expected to benefit from efficiency improvements and energy savings by new schemes such as de-signalization.

Crash risk assessment at unsignalized intersections using vehicle trajectory data

IATSS Research
Crash prediction models (CPMs) typically use statistical or data-driven approaches derived from observed crash data, but these can be limited by unreliable historical data.

Inter-Vehicle Communication Protocol Design for a Yielding Decision at an Unsignalized Intersection and Evaluation of the Protocol Using Radio Control Cars Equipped with Raspberry Pi

Computers, 2019
The Japanese government aims to introduce self-driven vehicles by 2020 to reduce the number of accidents and traffic jams. Various methods have been proposed for traffic control at accident-prone intersections to achieve safe and efficient self-driving ...

Dynamic Modeling of VISSIM's Critical Gap Parameter at Unsignalized Intersections

, 2013
Critical gaps are essential parameters in the modeling of traffic operations at unsignalized intersections and roundabouts and are the main determinants in the calculation of intersection capacity. In microscopic simulation tools, critical gaps are basic
