Unsignalized intersection vehicle platoon formation scheduling method based on mixed traffic

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 ...

Critical Gaps at Unsignalized Intersections with Bending Right-of-Way

Communications, 2018
The capacity calculation procedure for unsignalized intersections is based on the gap-acceptance theory in most of existing capacity regulations and it relies on one of the important parameters - critical gap.

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 ...

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

Journal 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

Advanced Decision Making and Motion Planning Framework for Autonomous Navigation in Unsignalized Intersections

IEEE Access
Autonomous vehicle navigation relies heavily on integrating sensor data, perception, path planning, localization, and vehicle control. However, existing research often treats these components in isolation, particularly at unsignalized intersections ...

Critical conflict probability: A novel risk measure for quantifying intensity of crash risk at unsignalized intersections

IATSS Research
A significant number of traffic crashes are reported at unsignalized intersections. However, in developing countries, challenges such as underreporting and limited crash data hinder the direct correlation of traffic conflicts with reported crashes for ...
