Prioritizing Transit Markets Using Analytic Hierarchy Process
(American Society of Civil Engineers, 1994)The analytic hierarchy process (AHP) is a multicriteria decision‐making approach that can be used to allocate scarce resources. Although there has been an extensive application of AHP in many disciplines, very little is ... -
Analysis of Segmentation Algorithms for Pavement Distress Images
(American Society of Civil Engineers, 1993)Collection and analysis of pavement distress data is an important component of any pavement‐management system. Various systems are currently under development that automate this process. They consist of appropriate hardware ... -
Urban Trip Distribution in Practice. II: Quick Response and Special Topics
(American Society of Civil Engineers, 1993)The companion paper reviewed the state of the art of conventional analysis of urban passenger trip distribution. This part reviews the status of quick‐response analysis and special topics. The quick‐response analysis ... -
Field Test Comparison of Calcium Magnesium Acetate to Salt
(American Society of Civil Engineers, 1993)This paper focuses on the technical and operational aspects of calcium magnesium acetate (CMA) compared to those for salt for winter road deicing. The results are based on a winter road test conducted by the University of ... -
Effect of Truck Loads on Bridges
(American Society of Civil Engineers, 1993)This paper determines the truck‐load spectra for highway bridges. The weigh‐in‐motion data was collected at weigh stations located on Highways I‐75 and I‐94. The total number of trucks considered in this study is over ... -
Overall Delay, Stopped Delay, and Stops at Signalized Intersections
(American Society of Civil Engineers, 1993)Both stopped and overall delay are useful measures of intersection performance. While stopped delay is easier to measure, overall delay reflects better the efficiency of traffic signal operation. Ratio of overall to stopped ... -
Warping Stresses in Concrete Pavements on Pasternak Foundation
(American Society of Civil Engineers, 1993)This paper develops a solution of warping stresses in concrete pavement slabs resting on a Pasternak foundation. The solution is derived using the classical thin‐plate theory. Warping stresses in a slab of length -
Urban Trip Distribution in Practice. I: Conventional Analysis
(American Society of Civil Engineers, 1993)This paper reviews the state of the art of urban passenger trip distribution for conventional large‐ and small‐area analyses. The conventional large‐area analysis covers the following elements of trip distribution: preparing ... -
Risk and Capacity Impacts of ATC Separation Rules
(American Society of Civil Engineers, 1993)Some of the most significant factors in determining runway capacity are air traffic control regulations. Interaircraft separation regulations have been established to provide maximum safety to the travelling public. Thus ... -
Nonlinear FE Analysis of Plain Concrete Pavements with Doweled Joints
(American Society of Civil Engineers, 1993)Nonlinear finite element analysis of dowel‐jointed concrete pavements is presented. The nonlinearities considered are cracking of concrete in tension, compressive yielding of concrete, and loss of support due to lift‐off ... -
Airline Safety Posture: Evidence from Service‐Difficulty Reports
(American Society of Civil Engineers, 1993)This study looks at the concept of airline safety posture. This concept is introduced to reflect how well an airline is positioned for safety operations. Fortunately, airline accidents are far too rare for meaningful ... -
Investigation of Laboratory Fatigue Testing Procedures for Asphalt Aggregate Mixtures
(American Society of Civil Engineers, 1993)The primary purpose of this paper is to evaluate laboratory test procedures for measuring the fatigue response of asphalt paving mixtures. Available test methods are conveniently classified into the following categories: ... -
Risk‐Based Bridge Management
(American Society of Civil Engineers, 1993)This paper outlines a methodology for bridge project selection based on reliability methods and optimization procedures, which could serve as part of a bridge management system. The Markovian model is used to decay the ... -
Distributed Air‐Traffic Control. II: Explorations in Test Bed
(American Society of Civil Engineers, 1993)This is the second of two companion papers dealing with distributed planning for air‐traffic control. Three different organizational structures have been implemented: the local centralized architecture, and location‐centered ... -
Distributed Air‐Traffic Control. I: Theoretical Studies
(American Society of Civil Engineers, 1993)The present paper introduces some basic concepts and terminology of distributed planning, and describes a novel coordinator‐coworker structure—a control mechanism that can dynamically reorganize the planning system in ... -
Assessing Potential for Superhub Airport for California
(American Society of Civil Engineers, 1993)Increasing the United States' air‐transportation system capacity is a need expressed by air passengers, airlines, and aviation policymakers. This paper addresses the advantages and disadvantages of adding superhub (or ... -
Urban Traffic Noise in Riyadh, Saudi Arabia: Perceptions and Attitudes
(American Society of Civil Engineers, 1993)In a comprehensive two‐year research project, traffic noise was monitored at 42 locations in 13 districts in Riyadh, Saudi Arabia. A total of 2,095 individual heads of household were interviewed at the noise monitoring ...
