Buried Gas Pipelines Under Vehicular Crossings
(American Society of Civil Engineers, 1984)This paper describes and evaluates the various methods used in the analysis and design of buried pipelines under vehicular crossings extracted from a vast number of literature. It was found that a unified treatment of the ... -
System Preservation Needs
(American Society of Civil Engineers, 1984)Transportation planning has traditionally emphasized the analysis of major capital investments involving new facilities or significant capacity increases. In recent years, however, -
Predicting Porosity of Fired Soil Aggregates
(American Society of Civil Engineers, 1984)The porosity of preformed fired soil aggregates for pores larger than 0.05 μm in radius (POR), which mainly determines the potential of bitumen absorption, cannot be successfully correlated to a single soil property. ... -
In‐Service Buckling of Heated Pipelines
(American Society of Civil Engineers, 1984)Compressive forces may be induced in pipelines by the restraint of axial extensions due to temperature changes or other causes. These forces may cause vertical or lateral buckling of the pipeline. These two buckling modes, ... -
Indirect Transportation Energy
(American Society of Civil Engineers, 1984)Construction, maintenance, and operation of transportation infrastructure and vehicles represent a substantial energy investment. This indirect energy consumption per vehicle kilometer was estimated for auto, bus, and rail ... -
Modal Split in Recreational Transport Planning
(American Society of Civil Engineers, 1984)Recreational modal split is examined in a study area consisting of two groups of Greek islands, resorts, one in the Central Aegean where available modes are conventional ship and airplane, the other in the Argosaronikos ... -
Simulation Model Applied to Japanese Expressway
(American Society of Civil Engineers, 1984)In Japanese expressway systems, congestion occurs on many sections around large urban areas. In order to investigate countermeasures for these bottleneck sections, a traffic simulation model is developed which computes ... -
Wind Tunnel Investigations of Natural Ventilation
(American Society of Civil Engineers, 1984)Requirements for similarity of natural ventilation in wind tunnel models and experimental methods for evaluating its effectiveness are reviewed and tested in a 1:25 wind tunnel model of the Florida Solar Energy Center ... -
Aircraft Stand Assignment to Minimize Walking
(American Society of Civil Engineers, 1984)Modern airport terminal building designs that have finger piers and airbridges sometimes result in significant walking distances for passengers. For a given set of aircraft parking positions next to a passenger terminal ... -
Deterioration Rates of Concrete Bridge Decks
(American Society of Civil Engineers, 1984)Procedures are developed for estimating the parameters required for life‐cycle costing of the elements of maintenance and rehabilitation of concrete bridge decks subject to the deteriorative effects of deicing chemicals. ... -
Human Factors in Highway Design and Operations
(American Society of Civil Engineers, 1984)Highway design and operational suitability is largely based on the ability of drivers to use the roads safely and efficiently. Designers and highway and traffic engineers should have an appreciation of basic human factor ... -
Prediction of Bridge Accident Rates
(American Society of Civil Engineers, 1984)A technique is developed to predict bridge accidents. These collisions are complex occurrances influenced by many factors. Previous research found as many as ten items contribute to a structure's potential for collisions. ... -
Effective Width of Pedestrian Corridors
(American Society of Civil Engineers, 1984)Pedestrians walking in corridors tend to maintain a clearance from the walls and any stationary obstacles that they pass, thus, space within corridors is never fully utilized. A number of researchers have, therefore, ... -
Erratum: “Mudslide Effects on Offshore Pipelines” by Richard C. Swanson and Warren T. Jones (November, 1982)
(American Society of Civil Engineers, 1983) -
Pipe Restraints: Design Fallacies
(American Society of Civil Engineers, 1983)Harnessing is a technique of resisting thrust in pipe bends where it is judged to be a more economic alternative than casting anchor blocks, or where the ground in which pipe is buried is weak or unstable and, thus, is ... -
Closure to “<i>Protection of Pipelines Subject to Surcharge Loads</i>” by Eugene M. Kovach (November, 1982)
(American Society of Civil Engineers, 1983) -
Cost Functions for Transportation Systems
(American Society of Civil Engineers, 1984)A methodology for developing predesign cost estimation functions of transportation systems is developed and applied. The emphasis is on the methodology and the evaluation of the estimation equation, the goodness of which ... -
Pipeline Shore Approach: Analysis and Design
(American Society of Civil Engineers, 1983)A rationalized method utilizing the theory of wave refraction and soil liquefaction is presented for the analysis and design of a pipeline shoreapproach. The bending of wave train due to bottom contours near shore and the ... -
Variance of Vehicle Change Intervals
(American Society of Civil Engineers, 1983)A statistical analysis is presented of the length in time of the vehicle change interval, i.e., the sum of the yellow and all red times, for an approach to a signalized intersection. The analysis is based on a widely ... -
Optimal Signal Settings Over Transportation Networks
(American Society of Civil Engineers, 1983)Several recent papers have discussed the shortcomings of a simple approach for determining traffic signal settings over a network. This procedure iteratively sets signal timings at each intersection to minimize delay, ...
