Modeling Reliability of Train Arrival Times
(American Society of Civil Engineers, 1996)This paper deals with the scheduling of trains so as to minimize train trip times while maximizing reliability of arrival times. The amount of risk of delay (RD) associated with a schedule is used as the reliability component ... -
Closure to “Reliability of Underground Pipelines Subject to Corrosion” by M. Ahammed and R. E. Melchers

(American Society of Civil Engineers, 1996) -
Discussion: Reliability of Underground Pipelines Subject to Corrosion
(American Society of Civil Engineers, 1996) -
Book Review
(American Society of Civil Engineers, 1996) -
Finite-Element Analysis of Temperature Effects on Plain-Jointed Concrete Pavements
(American Society of Civil Engineers, 1996)The finite-element study of the effect of temperature variation on plain-jointed concrete pavements is presented. Temperature variation causes curling and thermal-expansion stresses. Curling stresses result from temperature ... -
Reliability-Based Model for Predicting Pavement Thermal Cracking
(American Society of Civil Engineers, 1996)Thermal cracking of asphalt pavements is a serious problem in Canada and the northern parts of the United States. On many occasions, either at the design stage or during service, highway agencies demand a forecast of ... -
Design and Analysis of Approach Terminal Sections Using Simulation
(American Society of Civil Engineers, 1996)Turned-down guardrail terminal sections were analyzed using LS-DYNA3D, a dynamic, nonlinear, large deformation finite-element modeling package with capabilities for simulating vehicular impacts into roadside hazards. A ... -
Use of Pasternak Foundation Model in Concrete Pavement Analysis
(American Society of Civil Engineers, 1996)This paper examines the use of Pasternak foundation model in the analysis of load-induced concrete pavement deflections and bending stresses, as well as thermal stresses caused by warping of slabs. Using theoretical solutions ... -
Mechanistic-Probabilistic Vehicle Operating Cost Model
(American Society of Civil Engineers, 1996)In the face of an aging road infrastructure and shrinking highway maintenance budgets, optimizing the allocation of limited highway resources is paramount to the Saskatchewan Department of Highways and Transportation (SHT). ... -
Neural Networks and AASHO Road Test
(American Society of Civil Engineers, 1996)The American Association of State Highway Officials (AASHO) road test, conducted during the period of 1958 through 1960, was a factorial test of pavement durability that considered layer depths, axle load, and number of ... -
Modeling of Stratified Urban Trip Distribution
(American Society of Civil Engineers, 1996)Trip distribution analysis involves determination of the pattern of trip interchanges between land-use parcels or traffic zones using an appropriate analytical technique. The different analytical techniques available for ... -
Dynamic Analysis of Concrete Pavements Subjected to Moving Loads
(American Society of Civil Engineers, 1996)Dynamic response of concrete pavements subjected to moving loads is analyzed by using the three-dimensional (3D) finite-element method in conjunction with Newmark integration scheme. The dynamic vehicle-pavement-foundation ... -
New Approach to Roadway Performance Indices
(American Society of Civil Engineers, 1996)In 1964, Carey and Irick defined the present serviceability index (PSI) by assuming that the PSI can be expressed on a scale of 0 to 5 as the sum of a logarithmic function of slope variance, a quadratic function of mean ... -
School Children as Pedestrians in Cairo: Proxies for Improving Road Safety
(American Society of Civil Engineers, 1996)Road safety records in developing countries demonstrate that traffic accidents are one of the major causes for casualties. Accidents involving children contribute the highest percentage of total accidents. Several factors ... -
Operation of Airport Security Checkpoints under Increased Threat Conditions
(American Society of Civil Engineers, 1996)Many types of foreign and domestic crises can increase the concern over terrorist actions directed toward the U.S. commercial air transportation system. Government and airport officials respond to these threats by increasing ... -
Evaluation of Logit and Probit Models in Mode-Choice Situation
(American Society of Civil Engineers, 1996)Logit and probit models are statistical tools that are well suited to analyze modal split situation. Logit is superior to probit from the analytical point-of-view, whereas the probit has more reliable theoretical basis. ... -
Impact of Commuter-Rail Services in Toronto Region
(American Society of Civil Engineers, 1996)Ridership of the commuter-rail system that was implemented in the Greater Toronto Area (GTA) in 1967 increased at an annual, average compound rate of 11.4 until 1989. Demand has leveled substantially during 1990–94 and has ... -
Study of Parameters Affecting Impulse Response Method
(American Society of Civil Engineers, 1996)Even though the impulse response method is widely used in detecting defects under rigid pavements, the sensitivity of the method is not well understood. Modal time-history analyses were used to numerically simulate the ... -
Determining Rehabilitated Sewer Flow Capacity
(American Society of Civil Engineers, 1996)The flow capacity of existing sanitary and storm sewers is a significant issue when making decisions on the optimal method of rehabilitation. At times the resulting flow capacity is an important factor during the design ...
