System Size and Cost Structure of Transit Industry
(American Society of Civil Engineers, 1999)Knowledge of the cost and production structure of transit systems can be instrumental in uncovering an array of important information regarding their operation. Optimal fleet size and pricing, average and marginal cost, ... -
Granular Material Characterization for Mechanistic Pavement Design
(American Society of Civil Engineers, 1999)This paper presents a procedure for characterizing granular base and subbase materials to provide the properties needed by the mechanistic methods for pavement design. It includes repetitive testing under different confining ... -
Analysis of Road Surface Profiles
(American Society of Civil Engineers, 1999)This paper introduces a universal methodology for the analysis of discretely sampled sealed bituminous road profile data. Several hundred kilometers of Victorian (Australia) road profile data are analyzed in both the ... -
Double Left-Turn Lanes in Medium-Size Cities
(American Society of Civil Engineers, 1999)Given the increasing use of double left-turn lanes and the lack of methods to design and analyze them, there exists an urgent need to develop such methods. This paper describes work completed at North Carolina A&T State ... -
Behavior of Unsurfaced Airfields Supporting Operations of C-17 Aircraft
(American Society of Civil Engineers, 1999)The C-17 Globemaster III aircraft was developed by McDonnell Douglas (now Boeing) with the capability of transporting equipment and cargo to small airfields with short runways and minimal ground support equipment. The ... -
Stresses in Jointed Rigid Pavements
(American Society of Civil Engineers, 1999)A novel application of the principles of fracture mechanics combined with multilayered elastic theory is used to obtain the design stresses midway between the transverse joints at the bottom of the longitudinal edge of ... -
Comparison of Two Models Evaluating Automobile Safety Features
(American Society of Civil Engineers, 1999)Two existing models of automobile crashes are extended and compared to improve the evaluation of the performance of new, vehicle-based technologies for crash avoidance. The crashes model is based on knowledge of the ... -
Evaluation of Unsurfaced Airfield Criteria for Operation of C-17 Aircraft
(American Society of Civil Engineers, 1999)To determine the impact of C-17 aircraft on unsurfaced airfields, the U.S. Army Engineer Waterways Experiment Station was asked to construct full-scale pavement section items and traffic them to failure with a fully loaded ... -
Forensic Investigation of Pavement Distortions Using Soil Suction
(American Society of Civil Engineers, 1999)State Highway 6 in Brazos County, Tex., is experiencing significant changes in surface profile at several locations. The changes in surface profile were noticed within a few months after construction. They quickly became ... -
GIS Platform for Multicriteria Evaluation of Route Alignments
(American Society of Civil Engineers, 1999)The selection of an appropriate alignment for a proposed highway is determined largely by relating topographic, urban, and environmental features to geometric design controls. Typically, aerial photographs and topographic, ... -
Sensitivity Analysis for Estimation of Pavement Fatigue Life
(American Society of Civil Engineers, 1999)The fatigue life of pavements modeled as Winkler beams, with irregular profile, and traversed by vehicles modeled as nonlinear dynamic systems, is investigated in this article. Three computational methods are used to ... -
Estimating Vehicle Kilometers of Travel Using PPS Sampling Method
(American Society of Civil Engineers, 1999)The estimation of vehicle kilometers of travel at various levels of a road network is one of the key tasks of any road and transport authority. This paper introduces a method to estimate the vehicle kilometers of travel. ... -
Road Profile, Vehicle Dynamics, and Ride Quality Rating
(American Society of Civil Engineers, 1999)A great deal of research has been carried out over the past few decades in seeking explanatory variables to understand various human judgmental indices of road quality. The essential question is, What is a rater sensing ... -
Integration of Computer Supported Processes in Road Life Cycle
(American Society of Civil Engineers, 1999)This paper discusses the nature of problems encountered during the integration of software that separately supports the mutually integrated processes of road design, construction, and maintenance. A road model based on the ... -
Impact of Adaptive Signal Control on Major and Minor Approach Delay
(American Society of Civil Engineers, 1999)One of the primary difficulties in completing evaluations of real-time adaptive traffic signal systems has been the lack of effective modeling tools to perform controlled and repeatable analytical experiments. Recently, a ... -
Optimal Work Zone Lengths for Two-Lane Highways
(American Society of Civil Engineers, 1999)Highway pavement maintenance is very expensive not only in terms of costs to the responsible agencies, but also in terms of disruptive delays to users. Construction and maintenance activities on two-lane, two-way highways ... -
Probabilistic Approach to Pavement Design Based on Generalized California Bearing Ratio Equation
(American Society of Civil Engineers, 1998)In order to realize the thickness design of flexible pavements at a given probability level, supplementary analysis of the generalized -
Captivity Revisited
(American Society of Civil Engineers, 1999)Captivity to a choice is an aspect of the choice process that is not well understood in the transportation area. The current context of understanding of this phenomenon is superficial and covers only being physically ... -
Pavement Strain from Moving Dynamic 3D Load Distribution
(American Society of Civil Engineers, 1998)This paper presents the formulation and the application of a continuum-based finite-layer approach to evaluate pavement strain response under actual traffic loading. The model incorporates important pavement response ... -
Comparative Life-Cycle Cost Analysis of Underground Heat Distribution Systems
(American Society of Civil Engineers, 1998)An analytical model was developed to compare the life-cycle costs of two types of underground heat distribution systems: directly buried conduits and concrete trench installations. The costs of initial construction, routine ...
