The Rental User Study and Local User Study were conducted as part of the TravTek Operational Test Evaluation. TravTek was an operational field test of an advanced traveler information and traffic management system (ATIS/ATMS). As part of the test, 75 TravTek equipped vehicles were rented to Orlando visitors. Other TravTek equipped vehicles were sup

TRAVTEK WAS AN OPERATIONAL FIELD TEST OF AN ADVANCED TRAVELER INFORMATION SYSTEMS (ATIS) AND ADVANCED TRAFFIC MANAGEMENT SYSTEMS (ATMS) TECHNOLOGIES. THIS PAPER SUMMARIZESS THE FINDINGS FROM THE SERIES OF STUDIES THAT CONSTITUTED THE TRAVTEK EVALUATION. TWO FIELD STUDIES, THREE FIELD EXPERIMENTS, AND FOUR ANALYTICAL STUDIES ARE SUMMARIZED. THE RENT

The Invehicle Safety Advisory and Warning System (IVSAWS) is a Federal Highway Administration effort to develop a nationwide vehicular information system that provides drivers with advance, supplemental notification of dangerous road conditions using electronic warning zones with precise areas of coverage. The research study investigated techniques

THE FOLLOWING REPORT DESCRIBES A MODELING STUDY THAT WAS PERFORMED TO EXTRAPOLATE, FROM THE TRAVTEK OPERATIONAL TEST DATA, A SET OF SYSTEM WIDE BENEFITS AND PERFORMANCE VALUES FOR A WIDER-SCALE DEPLOYMENT OF A TRAVTEK-LIKE SYSTEM. IN THE FIRST PART OF THE MODELING STUDY, THE INTEGRATION SIMULATION MODEL WAS ENHANCED AND CALIBRATED TO PRODUCE A MODE

The purpose of this study was to develop and test word and symbol traffic control and hazard warning messages for use on portable changeable message signs (PCMSs). The literature was reviewed, State highway engineers were interviewed, PCMS manufacturers were surveyed, and motorists were questioned to develop an extensive list of candidate PCMS mess

There is a considerable emphasis on waste management at national, State, and local levels. Government at various levels has passed or is considering legislation or ordinances that mandate the recycling of waste materials or by-products. Reusing or recycling old, deteriorated pavement structure in the rehabilitation or reconstruction of a new struct

This document presents aggregate statistics derived from the 1994 Interstate Motor Carrier Inspection Database. The database was compiled from the records of driver-vehicle inspections conducted during Calendar Year 1994 by State and Federal officials responsible for commercial motor vehicle safety. The database is maintained by the Office of Motor

The U.S. Department of Transportation’s Small Business Innovation Research Program solicited proposals to develop an inexpensive visibility sensor to be used on highways to warn drivers of restricted visibility. Dense fog, dust storms, smoke, heavy rain, and snow have been known to cause multi-vehicle accidents. Systems have been developed to warn

This "Traffic Control Systems Handbook" updates the 1985 edition (FHWA-IP-85-11; TRIS 00475445) and broadens the scope to include Intelligent Transportation Systems (ITS) technology and concepts. The Handbook recommends decision-making processes in selection, implementation and operations of a traffic control system and describes ITS plans and prog

This report summarizes an analysis to identify performance measures to be used in comparing alternative Automated Highway Systems (AHS) concepts. This document type is resource materials.
In 1993. the Federal Highway Administration awarded a series of contracts under their Automated Highway Systems program. the contracts, which totaled 14.1 million, were awarded to 15 separate teams of researchers and were completed in late 1994. these contracts addressed the major issues and risks associated with automated vehicle control on our Na

One of the major evaluation goals of the TravTek operational test was to assess the safety impact of the TravTek system as implemented in Orlando, Florida during the 1 -year deployment phase. Also, the results of the TravTek operational test, with respect to safety, were to be used to estimate the potential safety impact of a TravTek-like system un

A set of very simple driving rules for single lane roadway traffic gives surprisingly realistic results. This observation can be backed up by theory, showing relations both to fluid-dynamical models for traffic, and to control system approaches to driving. Extensions to multi-lane traffic are straightforward and work well. Because of its simplicity

The purpose of this paper is to outline a methodology for the creation of a synthetic baseline population of individuals and households which can be used in activity-based travel models. While the populations developed here are necessary for microsimulations in these activity-based models, aggregated demographic characteristics of these populations

The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) broke significant ground in giving State and local decisionmakers greater discretion in the use of Federal transportation dollars. In particular, ISTEA’s flexible fund programs now provide transportation planners and decisionmakers with the flexibility to fund transportation proje

The publication of FHWA's A Guide to Reporting Highway Statistics was a significant milestone in unifying the data-reporting process. The Guide consolidated 16 reporting forms and provided instructions for reporting highway-related data on motor-fuel consumption, motor-vehicle registrations, driver licensing, and sources and funding of State and lo
