Fundamental Diagrams of Commercial Adaptive Cruise Control: Worldwide Experimental Evidence

no code implementations12 May 2021 Tienan Li, Danjue Chen, Hao Zhou, Yuanchang Xie, Jorge Laval

Experimental measurements on commercial adaptive cruise control (ACC) vehicles \RoundTwo{are} becoming increasingly available from around the world, providing an unprecedented opportunity to study the traffic flow characteristics that arise from this technology.

Dampen the Stop-and-Go Traffic with Connected and Automated Vehicles -- A Deep Reinforcement Learning Approach

no code implementations17 May 2020 Liming Jiang, Yuanchang Xie, Danjue Chen, Tienan Li, Nicholas G. Evans

Stop-and-go traffic poses many challenges to tranportation system, but its formation and mechanism are still under exploration. however, it has been proved that by introducing Connected Automated Vehicles(CAVs) with carefully designed controllers one could dampen the stop-and-go waves in the vehicle fleet.

A Deep Neural Networks Approach for Pixel-Level Runway Pavement Crack Segmentation Using Drone-Captured Images

no code implementations9 Jan 2020 Liming Jiang, Yuanchang Xie, Tianzhu Ren

In this study, runway pavement images are collected using drone at various heights from the Fitchburg Municipal Airport (FMA) in Massachusetts to evaluate their quality and applicability for crack segmentation, from which an optimal height is determined.
