Evaluation of Recycled Content Guardrail Posts
(American Society of Civil Engineers, 2002)In recent years, there has been an increased interest in the use of recycled materials in highway-related areas by state agencies and research organizations. In the present paper, guardrail posts manufactured from recycled ... -
Structural Behavior of Concrete Block Paving. II: Concrete Blocks
(American Society of Civil Engineers, 2002)In concrete block pavements, the blocks make up the wearing surface and are a major load-spreading component of the pavement. Earlier findings were inconsistent with respect to the deflection response of concrete blocks ... -
Reformulation of Asphalt Cements for Paving
(American Society of Civil Engineers, 2002)This paper summarizes research on the behavior of reformulated asphalt cements (AC) produced by different blending combinations of propane precipitated asphalt (PPA) and other petroleum-based components—soft asphalt residues ... -
Cluster Analysis for Optimal Sampling of Traffic Count Data: Air Quality Example
(American Society of Civil Engineers, 2002)Data collection is one of the most expensive tasks in many transportation-air quality studies. Finding effective ways to minimize data collection time and cost without losing vital information is crucial. This paper presents ... -
Cost-Based Space Estimation in Passenger Terminals
(American Society of Civil Engineers, 2002)Passenger processing space estimations described in textbooks and guidebooks are based solely on peak passenger demand and personal space standards describing perceived passenger comfort. The economic aspects of facility ... -
Estimating Heavy Vehicle Road Wear Costs for Bituminous-Surfaced Arterial Roads
(American Society of Civil Engineers, 2002)This paper provides the latest estimates of the attributable heavy vehicle road wear cost (load-related road wear)—which is an approximation for the marginal cost of road wear—for thin bituminous-surfaced arterial roads ... -
Full-Scale Field Tests of Discrete Fiber-Reinforced Sand
(American Society of Civil Engineers, 2002)The purpose of this investigation was to verify the results of an extensive laboratory experiment conducted to determine the effects of numerous variables on the performance of fiber-stabilized sand specimens. Laboratory ... -
New Methodology for Defining Level of Service at Toll Plazas
(American Society of Civil Engineers, 2002)Numerous measures of effectiveness are available to evaluate a toll facility for its level of service including density, volume-to-capacity ratio, and delay. Based on field research and data analyses, delay is recommended ... -
Discussion of “Soil Friction Restraint of Oblique Pipelines in Loose Sand” by Tung-Wen Hsu, Yuh-Jyh Chen, and Chun-Yin Wu
(American Society of Civil Engineers, 2002) -
Structural Behavior of Concrete Block Paving. I: Sand in Bed and Joints
(American Society of Civil Engineers, 2002)The quality of the bedding sand, jointing sand, joint width, and thickness of bedding course in concrete block pavement influence the performance of the entire pavement. A review of the literature revealed a wide range of ... -
Improving Freeway Speed Estimates from Single-Loop Detectors
(American Society of Civil Engineers, 2002)Many existing freeway traffic management systems (FTMS) use speed data from loop detectors as input to various traffic management functions, such as automatic incident detection, and to traveler information system components. ... -

Development of Coordinated Schedules using Genetic Algorithms
(American Society of Civil Engineers, 2002)Suburban trains and public buses can play a better role in public transportation if they are coordinated. Coordination of these two services will reduce the journeys made by intermediate public transport services and private ... -
Survey Design for Studying Transit Access Behavior in Mumbai City, India
(American Society of Civil Engineers, 2002)The decisions regarding data collection technique, instrument format, and sample design are crucial steps in any transportation planning. This paper presents the experiences of the writers with a pilot survey conducted for ... -
Faster Frank-Wolfe Traffic Assignment with New Flow Update Scheme
(American Society of Civil Engineers, 2002)The most widely used algorithm for solving traffic assignment problems is the Frank-Wolfe (FW) algorithm. Its popularity is attributed to its modest memory requirements and simplicity. However, it is also known that FW ... -
Benefit-Cost Analysis of Added Bicycle Phase at Existing Signalized Intersection
(American Society of Civil Engineers, 2002)A benefit-cost analysis framework is developed for an added bicycle phase at an existing signalized intersection. The intersection operates with both high volume levels of both vehicles and bicycles. As part of this study, ... -
Experimental Study of Breakaway Highway Sign Connections
(American Society of Civil Engineers, 2002)Highway signs require breakaway base connections. These connections will slip under impact, therefore preventing injuries to the occupants of an impacting vehicle. The breakaway connection works as long as the tension of ... -
Calibrating Simulation Models for Advanced Traveler Information Systems/Advanced Traffic Management Systems Applications
