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

open access: yesIET 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.

The Stability of Downtown Parking and Traffic Congestion [PDF]

open access: yes
In classical traffic flow theory, there are two velocities associated with a given level of traffic flow. Following Vickrey, economists have termed travel at the higher speed congested travel and at the lower speed hypercongested travel.

A Linear Model Predictive Control‐Based Ramp Metering Strategy for Traffic Flow Analysis in Continuous Multi‐Bottleneck Highway Segments

open access: yesIET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
This study proposes a linear model predictive control‐based ramp metering strategy for continuous multi‐bottleneck highway segments. By coordinating ramp inflows across the corridor using a linearized macroscopic traffic model, the approach significantly reduces travel time and congestion compared to conventional methods. Simulation results confirm its

Reinforcement Learning–Based Ramp Metering Strategy Considering Queue Management

open access: yesJournal of Advanced Transportation, Volume 2025, Issue 1, 2025.
This paper introduces an action replacement module for reinforcement learning (RL)–based ramp metering to address the issue of ramp queue spillback during the training process. Ramp queue spillback leads to significant impacts on the traffic efficiency of adjacent road networks, making it a critical concern in ramp control. Existing RL approaches often

Traffic Signal Setting at Urban Junctions and Fundamental Diagram: A Before–After Study

open access: yesJournal of Advanced Transportation, Volume 2025, Issue 1, 2025.
The paper analyses the effects of modifying traffic light regulations at urban road junctions, focussing on the ratio between green time and cycle time, as a function of vehicular traffic variables (flows, density and speed) on the links. The analyses are conducted in an urban setting using a before‐and‐after approach, employing traffic data detected ...

Effectiveness Evaluation of Signal Coordination Based on Spatially Sparse Trajectory Data

open access: yesJournal of Advanced Transportation, Volume 2025, Issue 1, 2025.
Signal coordination is an effective measure to improve the traffic efficiency of urban road networks, and network partition is an important part of it. Existing studies have proposed indicators based on the characteristics of arterial geometry and traffic flow to determine adjacent intersections that are suitable for signal coordination. However, it is

A Link Transmission Model with Variable Speed Limits and Turn-Level Queue Transmission at Signalized Intersections

open access: yes, 2023
The link transmission model (LTM) is an efficient and widely used macro-level approach for simulating traffic flow. However, the state-of-the-art LTMs usually focused on segment-level modelling, in which the traffic operation differences among multiple ...
