Multimodal Feeder Network Design Problem: Ant Colony Optimization Approach
(American Society of Civil Engineers, 2010)Significant service performance capabilities of high-capacity mass transit make it a remarkable part of any large metropolitan transportation system. Unfortunately it is not feasible to provide citywide direct access to ... -
Evaluation of the Effect of Pavement Roughness on Skid Resistance
(American Society of Civil Engineers, 2010)Roughness of a pavement surface is commonly correlated to its serviceability. On the other hand, on many occasions, investigators have attributed pavement roughness to inadequate skid resistance (friction) as well. However, ... -
How Does Transport Policy Cope with Climate Challenges? Experiences from the UK and Other European Countries
(American Society of Civil Engineers, 2011)Transport is one of the fastest growing sources of emissions of greenhouse gases. Some European countries have adopted comprehensive “sustainable transport” policies, in which climate change is addressed. This paper looks ... -
Comparative Analysis of Compact Multilane Roundabouts and Turbo-Roundabouts
(American Society of Civil Engineers, 2010)This paper presents a comparative analysis of the traffic performances of turbo-roundabouts and roundabouts in terms of capacity and delays. We chose to use a recent German procedure for roundabouts included in “Kreisel” ... -
Set of Comparable Carbon Footprints for Highway Travel in Metropolitan America
(American Society of Civil Engineers, 2011)The writers describe the development of a set of carbon dioxide emissions estimates for highway travel by automobile, truck, bus, and other public transit vehicle movements within the nation’s 100 largest metropolitan areas ... -
Travel Demand Model for Beijing 2008 Olympic Games
(American Society of Civil Engineers, 2010)The Beijing 2008 Summer Olympic Games was held from August 8 to 24, 2008, which definitely drew attention from all walks of life at home and abroad. Beijing 2008 Olympic Games was a great event, and there were huge demands ... -
Evaluation of Subgrade Strength and Pavement Designs for Reliability
(American Society of Civil Engineers, 2010)Reliability is an important factor in flexible pavement design to consider the variability associated with the design inputs. In this study, subgrade strength variability and flexible pavement designs are evaluated for ... -
Structural Deformation Characteristics of Installed HDPE Circular Pipelines
(American Society of Civil Engineers, 2010)This study presents a survey of deformation characteristics of the installed high-density polyethylene (HDPE) pipelines. Video and laser inspections are carried out on over 15,000 ft (4,572 m) of buried HDPE pipelines ... -
Integration of GIS and Data Mining Technology to Enhance the Pavement Management Decision Making
(American Society of Civil Engineers, 2010)This paper presents a research effort undertaken to explore the applicability of data mining and knowledge discovery (DMKD) in combination with Geographic Information System (GIS) technology to pavement management to better ... -
Modeling of Crack Depths in Digital Images of Concrete Pavements Using Optical Reflection Properties
(American Society of Civil Engineers, 2010)Digital image-based automated pavement crack detection and classification technology has seen vast improvements in the recent years. Although crack lengths and widths can be evaluated using state-of-the-art software with ... -
Real-Time Crash Risk Reduction on Freeways Using Coordinated and Uncoordinated Ramp Metering Approaches
(American Society of Civil Engineers, 2010)This study was conducted to examine the ability of two ramp metering strategies at reducing the real-time crash risk along a typical urban freeway. The strategies were tested using a simulated freeway network of Interstate-4 ... -
Development, Calibration, and Verification of a New Mechanistic-Empirical Reflective Cracking Model for HMA Overlay Thickness Design and Analysis
(American Society of Civil Engineers, 2010)The purpose of this paper is to present a new mechanistic-empirical (ME) reflective cracking model developed for hot-mix asphalt (HMA) overlay thickness design and analysis. After reviewing existing models, the reflective ... -
Simulation-Based Assessment of Vehicle Safety Behavior under Hazardous Driving Conditions
(American Society of Civil Engineers, 2010)Future sustained economic growth of the nation very much depends on the reliability and efficiency of its highway infrastructure system. Some vehicles, such as trucks, emergency vehicles, and sport utility vehicles, often ... -
Estimation of Remaining Service Life of Flexible Pavements from Surface Deflections
(American Society of Civil Engineers, 2010)Remaining service life (RSL) has been defined as the anticipated number of years that a pavement will be functionally and structurally acceptable with only routine maintenance. Usually RSL is computed from pavement condition ... -
Moisture Susceptibility of Subgrade Soils Stabilized by Lignin-Based Renewable Energy Coproduct
(American Society of Civil Engineers, 2012)Sustainable use of biomass as a renewable source of energy can be an alternative solution to the cost of fossil-based energy and global warming. Production of biofuel from plant biomass results not only in bio-based energy, ... -
Mesh-Independent Fracture Modeling for Overlay Pavement System under Heavy Aircraft Gear Loadings
(American Society of Civil Engineers, 2010)Flexible overlay systems often fail before reaching their design life due to the occurrence of reflective cracking caused by stress concentrations in the vicinity of joints and cracks in the underlying pavement. In this ... -
Characterization of the Tensile Viscoelastic Properties of an Undamaged Asphalt Mixture
(American Society of Civil Engineers, 2010)All characterization of asphalt mixtures must begin with the properties of the mixture in an undamaged state. Subsequent tests of the mixture in different stress or strain states at a level to cause damage can be referred ... -
Relationship between Access Management and Other Physical Roadway Characteristics and Safety
(American Society of Civil Engineers, 2010)In the past, one of the primary focus areas for access management research has been on the physical characteristics of a roadway (i.e., signal spacing, unsignalized access spacing, and median openings) and their associated ... -
