Edge‐computing‐based operations for automated vehicles with different cooperation classes at stop‐controlled intersections

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
This article proposes an edge‐computing‐based CAV operation at a stop‐controlled intersection. It investigates different cooperation classes at a stop‐controlled intersection. The numerical experiments show that mobility and energy efficiency are improved as the cooperation class increases. Computational time is much reduced with the proposed framework.

Research of Stop Assistance Considering Visibility of Intersection

International Journal of Automotive Engineering, 2014
Crossing collisions caused by cognitive error often occur at unsignalized intersections. For the countermeasure, driver assistant systems that warn a driver against stop sign violation are researched and commercialized.

IMPLEMENTATION OF THE TRAFFIC CONFLICT TECHNIQUE METHOD AT PONTIANAK'S UNSIGNALIZED INTERSECTION

Jurnal Teknik Sipil
The high number of traffic accidents is a problem for the government in realizing traffic security, safety, and smoothness. Intersections are the most common point of conflict, especially unsignalized intersections.

Enhancing Intersection Safety at Uncontrolled Three‐Legged Intersections Through Assessment of Risk

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
This study focuses on exploring the relationship between accepted gap and risk, as well as quantifying the level‐of‐risk and severity (LORS) to design effective safety measures for reducing accident severity at uncontrolled three‐legged intersections.

Trajectory Optimization for Automated Vehicles of Different Cooperation Classes Using Reinforcement Learning at a Signalized Intersection

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
1) A trajectory optimization method based on RL was proposed. 2) The performance in C‐ADS‐equipped vehicles of different cooperation classes was investigated. 3) Allowing optimization of hyper parameters offered more robustness. 4) The intersection performance indicators were validated through simulation.

Automatic Driving Passage Strategies for Signal‐Free Pedestrian Crosswalks Using an Improved Responsibility‐Sensitive Safety Model

Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.
Signal‐free crosswalks are a high incidence area for pedestrian–autonomous vehicles (AV) conflicts, but there is no comprehensive and reasonable solution for AVs to safely and efficiently navigate through these conflict scenarios. To address this problem, this study proposes a responsibility‐sensitive safety (RSS) model specifically for pedestrian–AV ...

Experience in calibrating the VISSIM microscopic simulation model for an unsignalized intersection in Pekanbaru, Indonesia

IOP Conference Series: Earth and Environment
Traffic activity is unique and occurs throughout the region. All moving traffic movements cause a build up of vehicles when there are conflicts between vehicles and result in congestion, one of which is in the intersection area located on Jalan SM Amin ...

Real‐Time Traffic Conflict Prediction at Intersections: A Novel Approach Integrating Statistical Models and Machine Learning

Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.
Real‐time traffic conflict prediction is crucial for developing proactive safety management strategies and improving overall traffic safety. However, existing studies have failed to fully consider the entire process of traffic conflict generation at both signalized and unsignalized intersections.
