This report provides a review of past reports and papers concerned with traffic management and safety in highway maintenance and construction zones. Annotations of literature relevant to the two research projects are categorized and presented.
This report summarizes field evaluation results of two innovative approaches used by District 12 (Houston) of the Texas State Department of Highways and Public Transportation on for managing traffic during middle lane maintenance operations on a 3-lane urban freeway section. The two approaches are: 1. Traffic shifting with use of the shoulder. 2. T

Louisiana produces no naturally occurring skid resistant aggregate and, therefore, must import these aggregates at great expense.In an effort to extend the yield of these aggregates, a laboratory investigation was initiated to determine the feasibility of blending these aggregates with aggregates of less skid quality while maintaining good skid res

In 1967 the FAA appointed an advisory committee on radiation biology aspects of SST flight. Some of the committee members were subsequently appointed to a working group to study radiation exposure during air travel in conventional jet aircraft.Presented here, in some cases in revised form, is selected material from the final reports of the full com

This study was undertaken to determine the effects of 0.30 ppmv ozone on 40 men representative of airline pilots. All were medically fit; 20 were smokers and 20 were nonsmokers.Subjects were divided into two age groups, 40-49 years and 50-59 years. The experiments consisted of exposure to 0.30 ppmv ozone and, on another occasion, to air only for 3

To be effective, governmental funds for public transit services must be based on sound approaches for providing and distributing subsidies. This report provides a review of the impacts of current capital and operating grants programs. Recommendations are made for a combination of provider side subsidies and user-side subsidies. This funding option

Autopsy reports of 710 pilots involved in fatal general aviation accidents and received by the FAA for the years 1980-82 were reviewed to appraise the age-specific prevalence of coronary atherosclerosis among the autopsied group and compare findings with those of an earlier study of a similar pilot group. Sixty-nine percent of the autopsies on pilo

As air traffic control becomes increasingly automated, the various implications of this trend should be considered. One of the likely byproducts of highly automated air traffic control systems is an increase in boredom and monotony among controllers as a result of the anticipated reduction in task demands. Boredom and monotony are generally concede

Air pollution data were collected at six sites in Texas. The data have been screened, reduced, and put into 5-minute and 15-minute data records to form a large data base. These data are arranged for easy use for model development or evaluation. In this report, the development of a new pollutant dispersion model, TRAPS IIM is described. This new mod

This document is the transcription of an oral history interview by Professor Emory Johnson of the South Dakota State University of Kenneth R. Surry, bridge engineer with the state of South Dakota from 1920-1963. Discussion centers around the building of highway bridges across the Missouri River, with special focus of the lawsuit of the state agains

The purpose of this investigation was to determine the influence of the procedures used in handling asphalt-additive blends on the effectiveness of antistripping additives in asphaltic concrete. The additives were blended with the asphalt cements before shipment by tank truck to the hot mix plants. Laboratory tests were performed on samples of the
