Proceedings ArticleDOI
Traffic density estimation with the cell transmission model
TL;DR: Simulation results show that the SMM and CTM produce density estimates that are both similar to one another and in good agreement with measured densities on I-210, and the mean percentage error averaged over all the test days was approximately 13%.
Journal ArticleDOI
Dynamic Friction Model-Based Tire-Road Friction Estimation and Emergency Braking Control
TL;DR: In this paper, an adaptive control scheme for emergency braking of vehicles is designed based on a LuGre dynamic model for the tire-road friction, where the wheel angular speed and longitudinal vehicle acceleration information are used to design a fast convergence observer to estimate the vehicle velocity and the internal state of the friction model.
Journal ArticleDOI
Emergency Braking Control with an Observer-based Dynamic Tire/Road Friction Model and Wheel Angular Velocity Measurement
TL;DR: In this article, a control scheme for emergency braking of vehicles is designed, where the tire/road friction is described by a LuGre dynamic friction model, and the control system output is the pressure in the master cylinder of the brake system.
Journal ArticleDOI
Piecewise-Linearized Cell Transmission Model and Parameter Calibration Methodology:
TL;DR: The switching-mode model, the SMM, is presented; it is a piecewise-linearized version of Daganzo's cell transmission model (CTM), and a semiautomated method has been developed for calibrating the CTM and SMM parameters.
Journal ArticleDOI
Safe Platooning in Automated Highway Systems Part I: Safety Regions Design
Luis Alvarez,Roberto Horowitz +1 more
TL;DR: In this article, conditions to achieve safe platooning under normal modes of operation are investigated and the results obtained allow one to decouple the controllers for the regulation of the manuevers and the finite state machines that determine their proper sequence in AHS architectures.
