The Task Committee on Density Currents and Their Applications in Hydraulic Engineering operates under the Technical Committee on Hydrologic Transport and Dispersion. The Task Committee...
Basing Options for Lunar Oxygen for Manned Mars Missions
The use of lunar oxygen to support lunar space transportation reduces Earth launch mass requirements by a factor of 2. In this paper, the authors show that lunar oxygen can also reduce...
Space Station - New Venture/Old Problem
Four key operations-related costs are associated with the Space Station: (1) transportation, (2) data management, (3) sustaining engineering, and (4) integrated logistics. Life cycle cost...
The Physics of Sediment Transport by Wind and Water
Sponsored by a special projects committee under the guidance of the Sedimentation Technical Committee of ASCE. This collection contains noteworthy,...
New Roads for the Micro
Using microcomputers loaded with database software and Fortran programming, engineers are gaining control of pavement maintenance. A number of factors, from urban sprawl to constricting...
Transit Triumph
The 1988 Outstanding Civil Engineering Achievement is Boston's Southwest Corridor, chosen not only for its size, complexity and technology, but for its environmental, public...

Historical Changes in Highway Safety: 1966 - 1987
During the past several decades, substantial changes have occurred in the national economy and culture. Corresponding changes have taken place in the highway transportation system. While...
Current Status of Research and Implementation
A review of the effectiveness of roadway safety measures to reduce traffic accidents is given. This paper attempts to discuss in detail the current status of safety-related knowledge and...
Changing Requirements
There are three sections to the presentation. First, a discussion of the changing environment of highway transportation - what are the factors and variables that are changing in the world...
Air Safety?Programs and their Effectiveness
Airplane accidents have always had considerable media attention, particularly, when they involve large numbers of fatalities. Ever since the Airline Deregulation Act of 1978 and the air...
Railroad Safety Programs and Effectiveness
Safety in the railroad industry has been a matter of concern to employees, officers, federal agencies and the general public since railroads came into being. This paper summarizes the...
Allocating Public Funds: Morality and Constraints
The highway safety engineer is continually faced with the trade-off between expenditures for highway safety improvements and reductions in highway fatalities, injuries, and property damage...
The Federal Budgetary Process
The paper outlines the federal budget process as it affects highway safety programs. There are a variety of federal programs which come under the umbrella designation highway safety. Those...
Comparing Benefits of Safety and Non-Safety Programs
The objective of this presentation is to compare benefit-cost ratios for major highway construction projects to those for highway safety projects, such as: (1) new highways, (2) major...
A Case for Science-Based Road Safety Design and Management
What civil engineers do has a major effect on road safety. However, contrary to appearances, the level of safety built into roads is largely unpremeditated. Standards and practices have...
Highway Safety - Planning for the Future
Because motor vehicle traffic is expected to continue to grow, renewed efforts will be required to prevent the problem of motor vehicle crash deaths and injuries growing much larger than...
Highway Safety in 2010: Compromising Among Values
A prediction is made of the highway safety development, based on analysis of current crash data and expected improvements in highway safety. The paper includes discussions of travel mileage...
Plans and Programming for Highway Safety to the Year 2010
