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.

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.

Critical Gaps at Unsignalized Intersections with Bending Right-of-Way

Communications, 2018
The capacity calculation procedure for unsignalized intersections is based on the gap-acceptance theory in most of existing capacity regulations and it relies on one of the important parameters - critical gap.

How pedestrians actually jaywalk: fine-grained adaptive strategies revealed by roadside LiDAR

Transportation Research Interdisciplinary Perspectives
Jaywalking is widely studied as a compliance problem, yet what actually happens during the jaywalking process remains understudied. This study deploys roadside LiDAR at two urban intersections in Munich, Germany to decompose jaywalking into discrete ...

A cooperative control method for connected and automated vehicles at unsignalized intersection based on Monte-Carlo tree search

Journal of Traffic and Transportation Engineering (English ed. Online)
Enhancing the efficiency of traditional traffic light-based intersection control in intricate and dynamic traffic scenarios proves challenging due to vehicular queuing and frequent starts and stops. Addressing this challenge, a cooperative control method

Advanced Decision Making and Motion Planning Framework for Autonomous Navigation in Unsignalized Intersections

IEEE Access
Autonomous vehicle navigation relies heavily on integrating sensor data, perception, path planning, localization, and vehicle control. However, existing research often treats these components in isolation, particularly at unsignalized intersections ...
