Administrative license revocation (ALR) laws are based on objective chemical tests (blood, breath, or urine), similar to “illegal per se” criminal laws against impaired driving. Administrative license revocation allows police and driver licensing authorities to revoke the driver’s license swiftly, without long delays while waiting for a criminal tr

Certain air traffic control(ATC) centers experienced a series of major outages,some of which were caused by the Display Channel Complex or DCC-a mainframecomputer system that processes radar and other data into displayable images oncontrollers' screens. DCC outages caused by old, out-of-production equipmenthave disrupted airtraffic. The Federal Avi

This document defines terms and acronyms used in current Commercial Vehicle Information Systems and Networks (CVISN) documents and used in activities relevant to development of a national Intelligent Transportation System (ITS) system architecture for commercial vehicle operations (CVO). This document may serve as a basic reference foranyone who is

This is the Participants' Manual for a training program designed to encourage fire/rescue stations to become a community-based information and service center for life safety education and prevention issues. The course has two parts: (I) Promoting Child Passenger Safety in Your Community (3 hours) covers organizing a program that works; and (II) Und

The purpose of this report is to present background information and techniques for developing protection reference values (PRV) to use with child dummies in out-of-position (OOP) child/air bag interaction testing. This report summarizes the literature on injury criteria and protection reference values as it pertains to children. As the first part o

The Minnesota Department of Transportation (Mn/DOT) has experimented with the use of shingle scrap in hot mix asphalt (HMA) since 1990. To date, the source of the shingle scrap has been shingle manufacturers exclusively. The manufactured shingle scrap consists primarily of tab punch-outs but also contains some mis-colored and damaged shingles. Test

This report documents a study of the feasibility of using sign blanks constructed of reclaimed materials instead of conventional high-grade plywood and aluminum. Traditional sign substrates constructed of wood and aluminum currently are not designed according to engineering formulas. Lack of design and analysis procedures integrated with a set of p

In 1993, the FHW A proposed minimum levels of retroreflectivity for traffic signs. The minimum values are organized into four tables according to the color of the sign. Each table defines the minimum values as a function of different variables, such as type of sheeting, size of sign, and/or speed of road. This research study was conducted to evalua

This report evaluates the operation of freeway high-occupancy vehicle (HOV) lanes in Texas through calendar year 1995. As of the end of 1995, HOV lanes were in operation on the five following Houston freeways: 1) Katy Freeway (1-lOW); 2) North Freeway (l-45N); 3) Northwest Freeway (U.S. 290); 4) Gulf Freeway (l-45S); and 5) Southwest Freeway (U.S.

PASSER IV is a program for timing traffic signals in networks based on progression bandwidth optimization. This manual describes how to use PASS ER IV-96, Version 2 .1, to obtain optimal signal timings. PASSER IV is capable of optimizing signal timings for arterials as well as multi-arterial closed-loop networks. The program explicitly handles one-

One aspect of the TransLink™ research program is to have a laboratory where the ITS architecture and technologies can be explored, integrated, demonstrated, and showcased. An integral part of this laboratory is a data warehouse where historical and real-time data can reside. This report examines the best method for managing this data. After a brief

This report summarizes the accomplishments of the Texas A&M Intelligent Transportation Systems (ITS) Research Center of Excellence (RCE) during Fiscal Year 1995-96. The research program targets the intelligent transportation infrastructure. It focuses on three technical thrusts-public transportation, transportation management, and international bor

An instrumentation plan and installation techniques were developed for a full-scale asphalt concrete test pavement. Six asphalt pavement test sections were constructed over an asphalt-treated base, cement-treated base, New Jersey base, Iowa base, 8 inch 304 base and 6 inch 304 base. Upon completion of test sections, moisture, temperature, vertical

A laboratory study has been conducted with two aims in mind. The first goal wasto develop a description of how a cutting edge scrapes ice from the road surface. Thesecond goal was to investigate the extent, if any, to which serrated blades were better thanun-serrated or "classical" blades at ice removal.The tests were conducted in the Ice Research

The purpose of this report is to present background information and techniques for developing protection reference values (PRV) to use with child dummies in out-of-position (OOP) child/air bag interaction testing. Biomechanics experts agree that OOP PRV in the literature should not apply to frontal belt-restrained child occupants (using child restr

Since 1993, our research has focused on fine rescue management stratagies and on evaluation of turfgrass cultivars. This year, two studies were added, a barren acid-producing slope was revegetated and new tall and fine fescue trials were installed. The fine fescue trials and management studies proved valuable in fight of of this year's tall fescue

The Atlanta Traveler Information Showcase is a demonstration of what traveling in metropolitan areas is going to be like as intelligent transportation infrastructures continue to be built. Initially designed to run for four months (June 1 to September 30), the Showcase run has been extended for an additional five months until the end of February 19
