To improve the safety of ramp vehicles changing lane and to shorten the merging distance, this paper explores the dynamic game interaction properties of vehicles merging and the consistency of vehicles' decision-making behaviors at the macro-microscopic levels. Using the exiD dataset and evolutionary game theory, the merging behavior of ramp vehicles is modeled to explore the effects of different driving states on the evolutionary convergence of strategies. Based on the game cost theory, the lane choice behavior of mainline vehicles is modeled. Validated by SUMO software, the results show that the model in this paper can significantly improve the safety of vehicle merging and reduce the merging distance. The mainline vehicles are more inclined to change lane and cut out in advance when facing the ramp vehicles under the influence of the change of advantage in the subsequent game.

This study investigates the nonlinear dynamics of Brushless DC (BLDC) motors using the MATLAB/Simulink platform, emphasizing system identification through the Least Squares (LS) method and Nonlinear Autoregressive Network With Exogenous Inputs (NARX) models with variable regressors. Accurate data-driven models derived from these techniques are essential for designing efficient feedback control systems, enabling precise motor dynamics representation and facilitating early fault detection by identifying deviations from normal operation. A detailed simulation of the BLDC motor under no-load conditions is performed to analyze the speed response and ripple effects in torque and speed, underscoring the need for effective modeling and control.

In this study, finite element numerical simulations were used to investigate the deformation of critical vehicle components and the damage characteristics of the retaining wall at the end of the emergency escape ramp after the impact of a Ford 800 truck on the retaining wall of the refuge lane. A finite element model of the reinforced concrete retaining wall of the truck was created using the LS-DYNA (R11.0) program and the correctness of the constructed finite element model was confirmed by tests.

Introduction: Over the last decade, the increasing popularity of Micromobility Vehicles (MMVs) has led to profound changes in personal mobility, raising concerns about road safety and public health. Therefore, the effective characterization of their kinematic performances and safety boundaries is becoming crucial. Hence, this study aims to: (1) characterize the MMVs kinematic behaviors during emergency maneuvers; (2) examine how various power sources affect their performances; and (3) assess the suitability of a piecewise linear model for modeling their trajectories.

In addressing the inadequacies of bonded dust suppressants employed in mining road applications, a novel approach is proposed for the research and development of a multifunctional road surface dust suppressant. A moisturizing functional component was added to enhance the fluidity and penetration capabilities of the dust suppressant; it can improve the coupling efficiency between the dust suppressant and the dust particles and then enhance the strength and thickness of the cemented layer of the dust suppressant. Fenugreek gum is selected as the bonding functional component due to its abundance in hydrophilic groups, facilitating enhanced coupling compatibility among the functional components and improving the coupling strength and crush-resistant performance of the dust suppressant cemented layer.

Background: A ramp is an auxiliary roadway that facilitates the vehicles joining and leaving the main traffic stream of highway. Ramp areas are prone to road crashes because of the merging, diverging, and weaving traffic entering and leaving the highways.
Objectives: This study evaluates the differences in injury severity and influencing factors between single- and multi-vehicle crashes at ramp areas, with which the transferability assessment of models across time periods is considered.
