Symbiotic Evolution and Simulation of Motorized and Nonmotorized Vehicles at Right‐Turns

Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.
This paper constructs a dynamic crossing model for motorized and nonmotorized vehicles at right‐turn intersections based on the Lotka–Volterra framework. The study explores equilibrium points and stability conditions within the symbiotic evolution model.

Interventions for Increasing Pedestrian Visibility to Prevent Injury and Death: A Systematic Review

Health &Social Care in the Community, Volume 2025, Issue 1, 2025.
Background Pedestrian visibility is a critical factor in reducing the number of pedestrian accidents on roads. A review of pedestrian visibility literature may reveal different types of interventions that are feasible for promoting pedestrian visibility.

MPC‐Bi‐LSTM based control strategy for connected and automated vehicles platoon oriented to cyberattacks

IET Intelligent Transport Systems, Volume 18, Issue 12, Page 2586-2600, December 2024.
This paper designs a communication topology anomaly response system (CTARS) to ensure platoon safety, which consists of a trigger module based on TTC indicators to distinguish abnormal vehicle behavior and a control module based on MPC‐Bi‐LSTM to deal with cyberattacks.

Intersection decision making for autonomous vehicles based on improved PPO algorithm

IET Intelligent Transport Systems, Volume 18, Issue S1, Page 2921-2938, December 2024.
In this article, we improve the proximal policy optimisation (PPO) algorithm in deep reinforcement learning and propose an MSA‐PPO algorithm, which adopts the self‐attention mechanism for input data processing, effectively identifies and focuses on the most important information in the interaction between vehicles to improve the overall performance of ...

Evaluation of automated driving safety in urban mixed traffic environments

IET Intelligent Transport Systems, Volume 18, Issue S1, Page 2963-2976, December 2024.
The research process consisted of four steps. Step 1: The driving behaviour of an MV following an AV was analysed via DS. Step 2: The driving behaviour of the MVs in each section was implemented by adjusting the parameters of the IDM, a microscopic vehicle following the model.

Study on Collision Avoidance Behavior in the Social Force-Based Pedestrian–Vehicle Interaction Simulation Model at Unsignalized Intersections

Applied Sciences
Modeling pedestrian–vehicle interaction behaviors not only helps better predict the intentions and actions of traffic participants but also contributes to generating more realistic pedestrian trajectories for testing autonomous vehicles.

Critical conflict probability: A novel risk measure for quantifying intensity of crash risk at unsignalized intersections

IATSS Research
A significant number of traffic crashes are reported at unsignalized intersections. However, in developing countries, challenges such as underreporting and limited crash data hinder the direct correlation of traffic conflicts with reported crashes for ...

Procedure for Safe Distance Determination for Minor Movement Accomplishing at Unsignalized Intersections

Promet (Zagreb), 2011
A minor movement performed at unsignalized intersections is one of the most complex and most difficult actions in traffic. Drivers performing a minor movement make decisions based on the estimation of movement parameters of vehicles in the major street ...
