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.

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.

Influences of Waiting Time on Driver Behaviors While Implementing In-Vehicle Traffic Light for Priority-Controlled Unsignalized Intersections

Journal of Advanced Transportation, 2017
In-vehicle traffic lights that assist drivers in crossing intersections are in development; however, the availability of the in-vehicle traffic light will be limited if the waiting time of a vehicle is not considered in actual traffic conditions ...

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.

EVALUATING THE CONTRIBUTION OF PHYSICAL PARAMETERS ON THE SAFETY OF UNSIGNALIZED INTERSECTIONS [PDF]

Journal of Engineering Science and Technology, 2015
Safety of any particular Road way facility cannot be attributed to set of parameters specific to a certain domain. Unsignalized intersections are no exceptions, thus, making them an important area of study. This paper presents the results of the analysis

Modeling Crossing Conflicts at Unsignalized T-Intersections under Heterogeneous Traffic Conditions

Journal of Advanced Transportation, 2022
The safety of unsignalized intersections is evaluated by correlating the number of crashes with traffic volume and intersection geometry. However, crash-based safety assessment has known drawbacks related to data quality and coverage.

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 ...

Comparative analysis of pedestrian accidents risk at unsignalized intersections

The Baltic Journal of Road and Bridge Engineering, 2015
More than one accident of three that involve pedestrians in urban area occurs at road intersections. The users’ inproper behaviour, the geometrical characteristics of the intersections, and the high speeds of vehicles are the main causes of pedestrian accidents.
