Inspection of Under Bridge Length Culverts
Culverts over 20 feet in span length are classified as bridges and are inspected under the National Bridge Inventory and Inspection Program. Those facilities under bridge length, less...
Space Age Pueblo
If and when 8 million passengers decide to fly in and out of Albuquerque, N.M. in one year, the renovated and expanded airport will be ready for them. In a comprehensive $120 million project,...
CADD Adds Safety to the Ryan
Computer aided design and drafting (CADD) was used to plan safety improvements for the Dan Ryan Viaduct, a two mile expressway in Chicago. Some 17 accidents per day took place along the...
Roads for Sale
Due to the decline in available federal revenue for transportation facilities, privatization is becoming a common alternative to project financing. A case study of a public/private partnership...
Accommodation of Trucks on the Highway
Safety in Design
This book contains the papers presented at the symposium on accommodation of trucks on highways held in Nashville, Tenn., May 11, 1988. The papers address highway factors that contribute...
Analytical Studies of the Schoharie Bridge Failure
Analytical studies consisted of geomorphic, hydrologic, hydraulic, and erosion analyses including mathematical modeling with HEC-1 and WSPRO, the new FHWA water-surface profile model....
Schoharie Creek Bridge Model Study
On April 5, 1987, a major storm occurred in the Schoharie Creek watershed and the resulting flood caused the bridge to fail. The hydraulic model of the bridge was performed to simulate...
A Simulation Technique for Modeling Flow on Floodplains and in Coastal Wetlands
The system design is premised on a proven, areal two-dimensional, finite-difference flow/transport model which is supported by an operational set of computer programs for input data management...
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...
Ten Top Projects for 1988
The other Outstanding Civil Engineering Achievement nominees make up an impressive collection of projects. They are notable for innovative management techniques, state-of-the-art engineering...
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...
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...
