Impact of Fuel Conservation Measures on Safe Truck Downgrade Speeds
(American Society of Civil Engineers, 1989)Runaway truck accidents are primarily due to brake fade and failure resulting from excessive temperature of the truck system brake components generated while descending severe downgrades. A grade severity rating system ... -
Analysis of Water Distribution Pipe Failure Types in Winnipeg, Canada
(American Society of Civil Engineers, 1989)A detailed examination of the pipe failure records for the City of Winnipeg, Canada, was performed. The failures were examined by age, type of failure, and degree of spatial and temporal clustering for each of the four ... -
Analysis and Design of RPM and Other Composite Underground Pipelines
(American Society of Civil Engineers, 1989)Glass‐fiber‐reinforced plastic mortal' pipes had been in use for pressure and nonpressure underground applications since 1965. Although this material had been used on many projects, the loads imposed on these piplines had ... -
Use of Binary Choice Decision Process for Adaptive Signal Control
(American Society of Civil Engineers, 1989)Adaptive signal control based on a binary‐choice decision process for timing adjustment has the potential to replace traffic‐actuated control. This emerging control strategy divides time into small intervals. In each ... -
Effect of Platoons on Permissive Left‐Turn Capacity: Pilot Study
(American Society of Civil Engineers, 1989)Existing models for estimating left turn capacity assume an average opposing flow rate throughout the cycle. While this assumption may be valid under random arrivals, it is evident that the presence of platoons results in ... -
Seismic Risk Analysis of Buried Pipelines
(American Society of Civil Engineers, 1989)A procedure is described for the seismic risk analysis of buried pipelines that provides an estimation of the annual probability of occurrence of different damage states, called damage indexes, in a component segment of ... -
Viscoelastic Approach to Modeling Performance of Buried Pipes
(American Society of Civil Engineers, 1989)A viscoelastic solution for a pipe buried in a homogeneous and isotropic soil is presented. The linear viscoelastic solution is obtained by transforming Hoeg's elastic solution using the (correspondence principle.) To ... -
Analysis of Heavy Truck Accident Data—Exposure Based Approach
(American Society of Civil Engineers, 1989)Measures of exposure used in accident analysis are complex and have been a topic of continuing research. There is a lack of agreement among traffic researchers as to what constitutes exposure to accident. Exposure, in its ... -
Model Study of Safety Grating for Culvert Inlet
(American Society of Civil Engineers, 1989)The design of a safety grating for a culvert inlet as investigated using a physical model. The objectives of such a grating are: (1) To prevent a person who falls into the drainageway from being carried into and through ... -
Methodology for Optimal Design of a Parking Lot
(American Society of Civil Engineers, 1989)A new approach to optimal design, maximum capacity, and the best layout for parking maneuvers, of a corner lot for parking spaces is introduced. Certain assumptions and practical design principles are used to derive the ... -
Pumping Prediction Model for Highway Concrete Pavements
(American Society of Civil Engineers, 1989)Pumping prediction models are important in the design and economic analysis of rigid pavements. A review of several pumping models, as well as the one developed by the writers, is presented in this paper. Pumping modeling ... -
Bus‐Ride Panel Rating of Pavement Serviceability
(American Society of Civil Engineers, 1989)In accordance with the concept of pavement serviceability rating, busride panel rating should logically be employed for assessing the pavement serviceability of bus lanes and other road networks that are used predominantly ... -
Traffic Platoon Dispersion Modeling
(American Society of Civil Engineers, 1989)The objective of this work is to present the current state of the art in modeling the dispersion of traffic platoons, to present a new mechanism suggested by current models, and to test that mechanism with detailed field ... -
Intersection Ranking Methodology for Pedestrian Safety
(American Society of Civil Engineers, 1988)The concept for a method of constructing a pedestrian hazard index is developed using the following hazard indicators: number of pedestrian accidents; pedestrian accident rate; proportion of special pedestrians crossing; ... -
Noise and Air Pollution of High‐Speed Rail Systems
(American Society of Civil Engineers, 1989)Transportation noise and air pollution problems are a nemesis to our modern society. Each transportation system, high‐speed rail (HSR) included, has its own noise spectra, characteristic air pollutant emissions, and ... -
Foreword

Capital Cost and Operations of High‐speed Mail System in West Germany
(American Society of Civil Engineers, 1989)The situation of the present Intercity system of the German Federal Railroad is described. The current construction of new lines, and the future highspeed InterCity Express system, which will increase operating speeds up ... -
HSR Vehicle Performance Characteristics
(American Society of Civil Engineers, 1989)Maximum train speed is usually considered the paramount performance characteristic for a high‐speed rail system. However, there are other vital characteristics, and by applying an operations research approach, these important ... -
Operating and Maintenance Costs of the TGV High‐Speed Rail System
(American Society of Civil Engineers, 1989)In the first section, operating results are reported for the TGV high speed trains ( -
High‐Speed Rail Track Design
(American Society of Civil Engineers, 1989)While the new generation of high speed rail (HSR) vehicles is generally accepted as an obvious necessity for HSR operations, the need for higher track standards for new HSR lines and high‐speed upgrades of conventional ...
