This report contains an evaluation of the sensing techniques and implementation issues of magnetic sensing as a position reference system. The field patterns of sample magnetic markers were first measured to illustrate the basic characteristics of such systems. Several sensing approaches were...

Keywords longitudinal control, car platooning, back-stepping control, multi-surface dynamic sliding mode control, integral filters, realtime control code This report presents the development of nonlinear longitudinal controllers and their realtime implementation for Automated Highway Systems...

This report presents the work on the development of the regulation layer for automated merging. It includes system modeling, control system synthesis, theoretical analysis and real-rime implementation and field test. The essential part is a rather general adaptive merging algorithm. Key words:...

This report details the PATH proving test results during the period of October 6 to December 1, 2000 on the test track of the Public Works Research Institute (PWRI) of the Ministry of Construction in Tsukuba City, Japan. This work is related to the "Attachment 5: System Evaluation by Proving...

This project is a one-and-half year research and experimental effort to investigate the implementation of the precision docking system on a bus and to demonstrate that the system can provide superior docking accuracy. Since a bus cannot be secured for docking experiments during the period of the...

This paper describes the development process and some preliminary findings for the human-machine interface (HMI) component of a system to aid snowplow operators. The HMI was developed though a series of driver task explorations and prototype tests. The HMI design has resulted in positive driver...

This project is a one-and-half year research and experimental effort that builds on the results of as well as supplements the efforts in MOU 250, "Experimental Studies on Vehicle Control Systems." It focuses on an emerging issue of the high-speed steering control: how to conduct robust automatic...

Traffic data is used to estimate current traffic conditions so that travelers and agencies can make better decisions about how to use and manage the transportation network. This research explores the fusion of probe data (vehicle speed and direction) with loop data (density, speed, and count) in...
