Hydraulic Transport of Fine and Coarse Sediment Mixtures in Pipelines
(American Society of Civil Engineers, 2002)This paper presents results from a comprehensive laboratory study of the effects of a fine grained sediment (clay) carrier fluid on the hydraulic gradient of sand-sized sediments (600–2,000 microns) in a 103-mm diameter ... -
Drivers’ Parking Decisions: Advanced Parking Management Systems
(American Society of Civil Engineers, 2002)Advanced Parking Management Systems use variable message signs to provide drivers with up-to-date information on the number of open spaces at selected parking lots throughout a city. Drivers passing a variable message sign ... -
Macroscopic Optimum System for Management of Pavement Rehabilitation
(American Society of Civil Engineers, 2001)A macroscopic pavement management system has been designed to yield optimum pavement conditions under constrained budgets. The system can predict future pavement conditions from performance curves generated using the ... -
Optimal Setback Planning and Delay Analysisfor HOV Lanes
(American Society of Civil Engineers, 2001)To maximize the potential for success of an urban high-occupancy vehicle (HOV) lane, there are several design intricacies that require special attention, particularly at critical intersections. This paper is based on ... -
Test of Recycled Concrete Aggregate in Accelerated Test Track
(American Society of Civil Engineers, 2001)This paper reports the findings of a project on evaluating the performance of recycled concrete aggregate (RCA) for use as a base material under hot mix asphalt pavements and as an aggregate in portland cement concrete ... -
Influence of Supporting Base Characteristics on Shrinkage-Induced Stresses in Concrete Pavements
(American Society of Civil Engineers, 2001)This paper presents an analytical model for prediction of shrinkage-induced stresses and displacements in concrete pavements due to the restraint of the supporting base. The model relies upon the interfacial friction stress ... -
State-Specific Vehicle Noise Emission Characteristics
(American Society of Civil Engineers, 2001)During the period of September 1999 through March 2000, the University of Louisville Research Foundation conducted a series of reference energy mean emission level (REMEL) measurements of individual vehicle operations in ... -

Modeling and Experimental Measurements of Strain Distribution in Asphalt Mixes
(American Society of Civil Engineers, 2001)The objective of this study is to experimentally and theoretically estimate the strain distribution in an asphalt binder as it exists in hot mix asphalt (HMA). This is important to evaluate whether the strain magnitudes ... -
Modeling Traffic Delays at Northern New York Border Crossings
(American Society of Civil Engineers, 2001)Border crossings in northern New York are important to international trade and tourism. How traffic operations at these crossings can be made more efficient has been a concern to the New York State Department of Transportation ... -
Identifying Black Spots along Highway SS107 in Southern Italy Using Two Models
(American Society of Civil Engineers, 2001)Black spots (BS) are highway locations where the potential for accidents is unacceptably high when compared to the established risk tolerance criteria. It is argued in this paper that to effectively utilize available funds ... -
Developing Spectrum-Based Models for International Roughness Index and Present Serviceability Index
(American Society of Civil Engineers, 2001)This paper presents a theoretical model for determining international roughness index (IRI) and present serviceability index (PSI) in term of power spectral density (PSD) roughness. Frequency response functions of quarter-car ... -
Incorporating Uncertainty and Multiple Objectives in Real-Time Route Selection
(American Society of Civil Engineers, 2001)There is a requirement in real-time, routing information systems to identify the “optimal” route based on the multiple objectives and the individual decision-making rules of the users. While a number of utility theory-based ... -
Calibration-Free Arterial Link Speed Estimation Model Using Loop Data
(American Society of Civil Engineers, 2001)This paper presents a calibration-free model to estimate the average speed of moving vehicles in a link, from the upstream intersection until 40–60 m from the downstream intersection's stop line. The proposed model calculates ... -

Vehicle Dynamics Model for Predicting Maximum Truck Acceleration Levels
(American Society of Civil Engineers, 2001)The paper presents a simple vehicle dynamics model for estimating maximum vehicle acceleration levels based on a vehicle's tractive effort and aerodynamic, rolling, and grade resistance forces. In addition, typical model ... -
Application of Neural Networks to Estimate AADT on Low-Volume Roads
(American Society of Civil Engineers, 2001)Artificial neural networks are applied as a means of estimating the average annual daily traffic (AADT) volume from short-period traffic counts. Fifty-five automatic traffic recorder sites located on low-volume rural roads ... -
Predicting Drag Coefficient of Pneumatic Capsule
(American Society of Civil Engineers, 2001)This research compares various methods for determining the drag coefficient of a capsule moving through a pneumatic capsule pipeline. A theoretical drag coefficient equation is derived using the 1D energy equation, continuity ... -
Using Genetic Algorithms to Evaluate Aircraft Ground Holding Policy in Real Time
