An enhanced approach for weaving area capacity estimation combining high‐fidelity simulation and interpretable machine learning

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 25, Page 4273-4295, 20 October 2025.
Abstract Accurately assessing weaving area capacity is critical for optimizing traffic management. However, transportation agencies face a persistent challenge: Existing capacity models often inadequately characterize vehicle weaving behaviors and fail to quantify the interactions between influencing factors.

Federated Robust Embedded Systems: Concepts and Challenges [PDF]

, 2012
The development within the area of embedded systems (ESs) is moving rapidly, not least due to falling costs of computation and communication equipment. It is believed that increased communication opportunities will lead to the future ESs no longer being ...

Urban Transformations, Emergencies, and Disasters in Los Angeles: Constructing Civilian Unpreparedness as a Public Policy Issue (1940–1980) 洛杉矶的城市转型、紧急情况和灾害:将公民的准备不足建构为公共政策问题(1940年至1980年) Transformaciones Urbanas, Emergencias y Desastres En Los Ángeles: La Construcción De La Falta De Preparación Civil Como Un Problema De Política Pública (1940–1980)

Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 3, September 2025.
ABSTRACT This article explores the sociohistorical construction of civilian unpreparedness as a public policy issue in Los Angeles, arguing that it emerged not as a neutral response to escalating urban risks, but as a mechanism through which actors negotiated power dynamics amid urban transformations between 1940 and 1980.

Deep Q‐network based multi‐layer safety lane changing strategy for vehicle platoon

IET Intelligent Transport Systems
The vehicle platoon lane changing is significant for alleviating road congestion and diminishing transportation energy consumption. However, the lane changing strategy for a group of vehicles is still a great challenge in this field.

Computation of Time Delay Stability Margin for the Automated Vehicular Platoon

Complexity, 2020
Due to the limited band width and congestion of communication channels in the wireless vehicle-to-vehicle (V2V) communication, time delay inevitably arises and dramatically leads to the disturbances for the automated vehicular platoon. This paper focuses

Neural Adaptive Sliding-Mode Control of a Bidirectional Vehicle Platoon with Velocity Constraints and Input Saturation

Complexity, 2018
This paper investigates the vehicle platoon control problems with both velocity constraints and input saturation. Firstly, radial basis function neural networks (RBF NNs) are employed to approximate the unknown driving resistance of a vehicle’s dynamic ...

Vehicle Platooning with Multiple Vehicle Look-ahead Information

IFAC-PapersOnLine, 2017
Abstract In this work, we consider the effects of multiple vehicle look ahead in a vehicle platoon that employs a constant spacing policy (CSP) based controller in the presence of parasitic lags. We first consider a CSP controller for longitudinal dynamics that uses position, velocity and acceleration from ‘r’ predecessor vehicles.
