Analysis and Design Optimization of Flexible Pavement
(American Society of Civil Engineers, 2000)A project-level optimization approach was developed to minimize total pavement cost within an analysis period. Using this approach, the designer is able to select the optimum initial pavement thickness, overlay thickness, ... -
Nature and Frequency of Secondary Conflicts at Unsignalized Intersections
(American Society of Civil Engineers, 2000)This research aims to shed more light on the nature and frequency of secondary conflicts. Data for 15 unsignalized intersections located in Amman, Jordan, were collected by the use of a video camera. It was concluded that ... -
Evaluation of Highway Consistency and Safety: Practical Application
(American Society of Civil Engineers, 2000)Current design practices in North America are based mainly on 2D analysis of the highway alignment and do not account for the operating speed adopted by drivers. A more accurate approach should consider the interaction ... -
Use of Vehicle-Collected Data to Calculate Existing Roadway Geometry
(American Society of Civil Engineers, 2000)The Federal Highway Administration has designated Highway Design Practices and Criteria as a high-priority research and development area. New design standards need to be developed to provide quantitative guidance on alignment ... -
Physical and Mechanical Properties of Bituminous Mixtures Containing Oil Shales
(American Society of Civil Engineers, 2000)Rutting of bituminous surfaces on the Jordanian highways is a recurring problem. Highway authorities are exploring the use of extracted shale oil and oil shale fillers, which are abundant in Jordan. The main objectives of ... -
Impact Finite-Element Analysis of Slip-Base Sign Support Mechanism
(American Society of Civil Engineers, 2000)The slip-base design mechanism is used to support signs and luminaries in highways and is designed to break away in crashes with vehicles. This mechanism is intended to minimize occupant injuries by providing reduced ... -

State of the Art. II: Permanent Strain Response of Unbound Aggregates
(American Society of Civil Engineers, 2000)The permanent strain behavior of unbound aggregates under repeated loading has been studied by many researchers over the years. A summarized review of the research into this area is given based on the literature available ... -
State of the Art. I: Resilient Response of Unbound Aggregates
(American Society of Civil Engineers, 2000)The findings of an extensive literature survey on the structural response of unbound aggregates are discussed in two companion papers. In this paper, a state of the art is presented on resilient stress-strain characteristics ... -
Model for Determining Airline Fares for Meeting or Convention Demand
(American Society of Civil Engineers, 2000)This paper proposes an approach to determine zonal fares for the attendees of the meetings or conventions flying from different cities to a single host city. The airline has to offer a fare low enough to win the contract ... -
Temperature Distribution in Layered Road Structures
(American Society of Civil Engineers, 2000)An analytic framework dealing with heat movement in a three-layer pavement structure is set up based on the Fourier-Biot heat conduction equation. Exact analytic solution is obtained. The thermal characteristic frequencies ... -
Genetic-Algorithms-Based Approach for Bilevel Programming Models
(American Society of Civil Engineers, 2000)Many decision-making problems in transportation system planning and management can be formulated as bilevel programming models, which are intrinsically nonconvex and hence difficult to solve for the global optimum. Therefore, ... -
Simultaneous Service Approach for Reducing Air Passenger Queue Time
(American Society of Civil Engineers, 2000)Simultaneous service offers service-oriented organizations, such as the air passenger transportation industry, the opportunity to differentiate themselves by providing superior customer service. The concept of simultaneous ... -
Temperature Related Visco-Elastoplastic Properties of Asphalt Mixtures
(American Society of Civil Engineers, 2000)Parameter characterization of asphalt mixtures at various test temperatures is a crux to the performance evaluation of flexible pavements using the visco-elastoplastic method. But the difficulty of determining the relevant ... -
Capacity-Constrained Traffic Assignment in Networks with Residual Queues
(American Society of Civil Engineers, 2000)This paper proposes a capacity-constrained traffic assignment model for strategic transport planning in which the steady-state user equilibrium principle is extended for road networks with residual queues. Therefore, the ... -
Traffic Network and Distribution of Cars: Maximum-Entropy Approach
(American Society of Civil Engineers, 2000)The paper deals with the estimation of optimal distribution of cars in a traffic netework by slightly modifying the maximum-entropy principle. -
Effect of Dowel Looseness on Response of Jointed Concrete Pavements
(American Society of Civil Engineers, 2000)This paper examines the effect of dowel looseness on the structural response of jointed concrete pavements. A technique for modeling dowels in 3D finite-element analyses of rigid pavement systems is presented that relies ... -
Flexible Pavement Thermal Stresses with Variable Temperature
(American Society of Civil Engineers, 2000)A comprehensive analytical treatment of flexible pavement thermal stresses with variable temperature is presented in this paper. General solutions for equations of equilibrium expressed in terms of displacement and variable ... -
Comparison of Two Transportation Network Equilibrium Modeling Approaches
(American Society of Civil Engineers, 2000)Existing methodologies for predicting traffic flows on transportation networks involve a sequential process, often with four stages: trip generation, trip distribution, modal split, and traffic assignment. Although the ... -
Classification of Road Surface Profiles
(American Society of Civil Engineers, 2000)This paper introduces a universal classification methodology for discretely sampled sealed bituminous road profile data for the study of shock and vibrations related to the road transportation process. Data representative ...
