Multi‐Intersection Cooperative Control Platform Framework and Empirical Study in Connected and Automated Vehicle Environment: An Engineering Implementation Perspective

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
With the acceleration of urbanization and rapid growth of vehicle ownership, traffic congestion has become a critical bottleneck constraining sustainable urban development. Traditional traffic signal control methods struggle to adapt to the complex traffic environment where connected and automated vehicles (CAVs) coexist with conventional vehicles ...

Research on Collision Risk Warning Methods for Vulnerable Road Users at Unsignalized Intersections

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
Unsignalized intersections pose high collision risks between motor vehicles and vulnerable road users (VRUs). To enhance safety, this study proposes a collision warning method integrating trajectory prediction and dynamic risk assessment. UAV aerial footage was processed using YOLOv7‐DeepSort for multiobject detection and tracking, constructing a high ...

Accuracy of critical gap estimates

Alexandria Engineering Journal, 2023
The critical gap is an important parameter in capacity models of unsignalized intersections. Although there are many methods for critical gap estimation, there is currently no approach or method available to determine how precise a calculated estimate is,

Research on the Information Security and System Security of the Zero‐Trust Framework—Taking an Intelligent Connected Vehicle Platoon as an Example

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
With the rapid development of artificial intelligence, in the open communication environment, interference and network attacks on intelligent terminals are more frequent. Therefore, communication security and system security issues in the intelligent platoons become hot topics. Motivated by these, the concept of zero trust was proposed.

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 ...

An Analysis of the Effects of Crash Factors and Precrash Actions on Side Impact Crashes at Unsignalized Intersections

Journal of Advanced Transportation, 2021
Annually, side impact crashes contribute to a significant proportion of road fatalities. These crashes typically occur as a result of traffic violations at intersections. This study contributes to efforts in addressing side impact crashes at unsignalized

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
