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.

A WSN‐Integrated Digital Twin Prototype Framework for Mitigating Urban Traffic Congestion and Vehicular Emissions

Journal of Sensors, Volume 2026, Issue 1, 2026.
This study presents a simulation‐driven digital twin (DT) prototype framework, designed around a wireless sensor network (WSN) style pipeline, to study congestion and vehicular emissions at an urban signalized junction. The architecture follows a sensing‐to‐edge workflow: detector‐like traffic measurements (counts and speeds) are published through an ...

Assessment of road network vulnerability using multilayer perceptron surrogates with automated closure propagation

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 28, Page 5325-5350, 28 November 2025.
Abstract Road networks face increasing disruptions, yet vulnerability assessment methods either oversimplify traffic dynamics or require extensive computational simulations. This research introduces a novel approach integrating traffic simulation, graph theory, and machine learning for efficient and accurate vulnerability assessment.

An adversarial diverse deep ensemble approach for surrogate‐based traffic signal optimization

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 5, Page 632-657, 17 February 2025.
Abstract Surrogate‐based traffic signal optimization (TSO) is a computationally efficient alternative to simulation‐based TSO. By replacing the simulation‐based objective function, a surrogate model can quickly identify solutions by searching for extreme points on its response surface. As a popular surrogate model, the ensemble of multiple diverse deep

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.

Volume warrants for major and minor roads left-turning traffic lanes at unsignalized T-intersections: A case study using VISSIM modelling

Journal of Traffic and Transportation Engineering (English ed. Online), 2018
The most common type of intersection improvement considered in Ghana is signalization. However, other actions such as the installation of left-turn lanes have been proven to improve the efficiency and safety of an intersection without the need for ...

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 ...
