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 ...

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.

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.

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 ...

Review, Testing and Validation of Capacity and Delay Models at Unsignalized Intersections
Promet (Zagreb), 2007 This paper deals with problems related to the capacity anddelay models at unsignalized intersections. The parameters ofvarious models are calibrated based on the on-site data obtainedin the countries where the models were developed.
