The Michigan Department of Transportation (MDOT’) is currently planning for the expansion of their current Advanced Traffic Management and Advanced Traveler Information Systems (ATMS and ATIS, respectively). Current ATMS and ATIS coverage include 32.5 freeway miles surrounding Metropolitan Detroit and an additional 212 freeway miles of coverage is

The 1993 traffic fatality count was 1,414, up 8.8% from the 1992 figure of 1,300. Compared with 1992, injuries were up 13.3% and total crashes were up 5.4%. These figures translated into a death rate of 1.6 per 100 million miles of travel, up from the 1992 death rate of 1.5. Exposure factors in 1993 showed increases in vehicle registrations and tra

Everett Transit's Comprehensive Plan provides the long-term framework to guide the development of public transportation services in Everett over the next twenty years. In this plan, Everett Transit clearly defines its mission, future direction and necessary actions. The plan is based on research, analysis and debate conducted over the past six mont

This report represents a continuation of analysis concerned with the patterns and methods of distributing grains and oilseeds from North Dakota. This series began with the analysis of 1956-57 data and was published in Agricultural Economics Reports 15, 17, 44, 56, and 86 and Agricultural Experiment Station Bulletin 462. The compilation and analysis

The objective of this report is to provide a benchmark for elevator managers in assessing performance, and supply a source for recognizing trends in the characteristics of North Dakota elevators.
The Wisconsin Department of Transportation has initiated a study into the feasibility of locating an intermodal passenger transportation facility in downtown Milwaukee. That feasibilty study requires an evaluation of a very wide range of alternatives. The last concerted effort to develop evaluation criteria for intermodal passenger transfer facilit

The purpose of this research is to evaluate the effectiveness of break, seat and overlay strategies for the retardation of reflective cracking in bituminous concrete overlays over PCC pavements. This is part of FHWA's special projects SP-202 in which Ohio, West Virginia and Kentucky are also participating. This report documents construction strateg

The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) provided the nation with a means of maintaining its existing infrastructure while laying the foundation for a national intermodal transportation system. ISTEA was passed to ensure that the United States would have an economically efficient, environmentally sound intermodal transpo

The initiation and growth of cracks in a fuselage lap joint were simulated. Stochastic distribution of crack initiation and rivet interference were included. The simulation also contained a simplified crack growth. Nominal crack growth behavior of large cracks was derived from the simulation results. These calculations implied that large cracks spe

In October 1993, a team of Federal, State, and local officials visited major centers in Europe where substantial national travel survey activities have been undertaken. Among the purposes of the visits were to seek out innovative methodological approaches to transportation survey design and operations, to review European experiences with different

This is the first revision to the Texas Highway Operations Manual which was issued in August 1992. This revision provides a means of implementing the results of research tasks performed as part of this study and completed since the publication of the Manual. The Texas Highway Operations Manual was developed for the Texas Department of Transportatio

This volume consists of a set of 24 presentations given at a conference for assessing the needs and opportunities for improving the performance of North American rail truck (or bogie) designs. The presentations start by giving an overview of the fundamentals of the standard "three-piece" truck design with several presentations on problems associate

Reducing congestion in our nation's urban areas has become a top priority nationwide for state departments of transportation. The recent development and construction of freeway management systems have begun to help reduce these problems. A major component of freeway management systems is the inductance loop detector. This research effort evaluated

The Clean Air Act Amendments (CAAAs) and the Congestion Mitigation Air Quality (CMAQ) program established in the Intermodal Surface Transportation Efficiency Act (ISTEA) mandate the evaluation of transportation control measure (TCM) emission impacts. These mandates have created an important role for the proper documentation and cost-effective evalu

This research report represents the sixth year of a ten-year research effort focused on quantifying urban mobility. This study contains the facility information for 50 urban areas throughout the country. The database used for this research contains information on vehicle travel, system length, and urban area characteristics from 1982 to 1991. Vario

This project investigated the operations and safety characteristics of left exit lane drops. As generally recognized, constructing left exits is to be avoided; however, when present, suggestions on methods to improve safety and operations are valuable. One alternative for better communicating to motorists the presence of a left exit lane drop is wi

The data gathered from rolling nearly 2800 rocks off several 0.25H:1V slopes into three differently shaped ditches (flat, 6H:1V and 4H:1V) was used to develop 12 design charts for rock fallout areas. The data were analyzed using simple statistical and graphical methods. The charts can be used to size fallout areas that satisfy specific rock catchin

The NHTSA Fiscal Year 1995 performance plan for the Government Performance and Results Act of 1993 (GPRA) is the second in the three year pilot phase of the Act. This plan differs from the FY 1994 plan in two respects: 1) it uses a different "performance based" structure for the Agency's program and2) there are some changes in the intermediate outc
