This report examines the interactions among different forms of communication, where travel is also considered a form of communication. Data for this study comes from 148 respondents to the "Activity Diary" survey instrument of the Davis Community Network (DCN) project, which obtained information...

A field experiment in Yokohama (Japan) reveals that a macroscopic fundamental diagram (MFD) linking space-mean flow, density and speed exists on a large urban area. The experiment used a combination of fixed detectors and floating vehicle probes as sensors. It was observed that when the somewhat...

Transportation Management Centers (TMCs) are focal points for monitoring and operating traffic management systems. As new technologies are developed through research in Intelligent-Vehicle- Highway Systems (IVHS), these TMCs will assume increasingly more importance as command and control centers...

The purpose of this report is to investigate the effect of selected parameter variations on the response of a platoon. The response of a platoon under different control algorithms is also examined. A four-car platoon with prescribed lead car dynamics was used for simulations and vehicles in the...

This study investigates issues concerning the implementation and impacts of lateral guidance/control systems and the phased implementation of these systems in exclusive-access High Occupancy Vehicle (HOV) lanes. The study is divided into 5 volumes. The objectives of each volume are as follows:...

This paper presents the preliminary findings of a first wave Broad Area survey, administered in November 1995, of the TravInfo Field Operation Test in the San Francisco Bay Area. The purpose of the survey was to define baseline attitudes, opinions and travel behavior of travelers for assessment...

Proper use of child passenger safety (CPS) systems is highly effective in reducing injury and fatality in traffic crashes. While use of CPS systems is increasing, use is not universal, and there is a high level of improper use. The Child Passenger Safety Initiative is an innovative program to...

In this paper, the authors, although agreeing that deployment is the ultimate goal of Intelligent Transportation Systems (ITS) research and funding, believe that there is not sufficient knowledge of how, why and when to deploy specific ITS functions They contend that continued research and...
