Evaluation of Temperature Influence on Friction Measurements
(American Society of Civil Engineers, 2011)Many aspects influence the skid resistance of a pavement surface including surface texture, tire characteristics, vehicle operations, and environmental factors. The objective of this paper is to quantify the temperature ... -
Development of a Model for Asphalt Pavement Skid Resistance Based on Aggregate Characteristics and Gradation
(American Society of Civil Engineers, 2011)Many research studies and field experiences have shown a strong relationship between wet-weather accidents and pavement skid resistance. Therefore, measurement methods and models are needed to evaluate the safety level of ... -
Efficient Simulation Techniques for Reliability Analysis of Flexible Pavements Using the Mechanistic-Empirical Pavement Design Guide
(American Society of Civil Engineers, 2011)Many sources of uncertainty are inherent in pavement design. These uncertainties must be incorporated systematically in a reliability analysis to compute their combined effects on the probability of failure of a given ... -
Evaluation of Adding Distance Information to Freeway-Specific Service (Logo) Signs
(American Society of Civil Engineers, 2011)Specific service (or logo) signs provide information on attractions, camping, lodging, food, and gas services on the mainline of limited-access highways in advance of the interchange that provides access to the services. ... -
Modeling the Behavior of Steel-Fiber Reinforced Concrete Ground Slabs. I: Development of Material Model
(American Society of Civil Engineers, 2011)Steel-fiber reinforced concrete (SFRC) brings favorable properties to concrete ground slabs. The use of the material is limited by the lack of an appropriate analysis method. This paper is the first in a series of two ... -
Development of Truck Loading Groups for the Mechanistic-Empirical Pavement Design Guide
(American Society of Civil Engineers, 2011)A key to the use of weigh-in-motion (WIM) traffic data for the -
Thermomechanical Characterization of Shape Memory Polymer–Based Self-Healing Syntactic Foam Sealant for Expansion Joints
(American Society of Civil Engineers, 2011)The failure of expansion joints is a leading cause for structural damage to bridge decks and concrete pavements. A fundamental requirement for sealant is that it should always apply a compressive stress to the concrete ... -
Data Analysis of Diversion and Dynamic Message Signs
(American Society of Civil Engineers, 2011)Dynamic message signs (DMS) are used in conjunction with other media to communicate traffic conditions, general information, and recommended diversion strategies to motorists. This study uses loop detector data from Richmond, ... -
Locating Urban Transit Hubs: Multicriteria Model and Case Study in China
(American Society of Civil Engineers, 2011)This paper presents a comprehensive model for ranking candidate location plans of multiple urban transit hubs, which can effectively capture various aspects of concerns in the transit hub location planning process, including ... -
Empirical Study of Driver Responses during the Yellow Signal Phase at Six Maryland Intersections
(American Society of Civil Engineers, 2012)This paper presents the analysis results of driver responses during a yellow phase, based on field observations of 1,123 drivers collected with a specially designed system from six signalized intersections of high crash ... -
Vehicle-Type Dependent Car-Following Model for Heterogeneous Traffic Conditions
(American Society of Civil Engineers, 2011)Car-following behavior forms the kernel of traffic microsimulation models and is extensively studied for similar vehicle types. However, in heterogeneous traffic having a diverse mix of vehicles, following behavior also ... -
Case Study of Motorcycle Use and Policy Analysis in Huizhou, China
(American Society of Civil Engineers, 2011)This paper analyzes the motorcycle usage and policies in Huizhou, China. Two sets of survey data were used in the study: one is Daily Trip Survey of Huizhou that was taken in 2004, and the other one is Resident Travel ... -
Secondary Coordination at Closely Spaced Actuated Traffic Signals
(American Society of Civil Engineers, 2011)This paper presents a method of addressing stochastic variation at closely spaced signalized intersections to provide secondary coordination to “minor” movements with significant traffic volumes. A neurofuzzy signal control ... -
Fundamental Insight into Signal Plan Transition Methods
(American Society of Civil Engineers, 2011)This paper describes, in detail, the concrete operational mechanisms of the Corridor Simulation (CORSIM)–embedded signal transition algorithms. Through detailed analysis of these transition algorithms, this study found ... -
Substructure Nonlinear Effects on Sleeper Design Pressure in Heavy Haul Railway Tracks
(American Society of Civil Engineers, 2011)This study focused on the effects of track substructure material nonlinearity on sleeper design pressure for conventional heavy haul railway ballasted railway tracks. The material nonlinearity was applied by using Mohr-Coulomb ... -
Evaluating the Cost-Effectiveness of Roadside Culvert Treatments
(American Society of Civil Engineers, 2011)Roadside cross-drainage culverts have been found to affect vehicle accident injury levels. As a result, highway designers have commonly used three safety treatments to protect errant motorists from striking culvert openings. ... -
Comparative Study on Temperature Stresses in Asphalt Material Using Nonlinear Viscoelastic Approach
(American Society of Civil Engineers, 2011)An accurate estimate of temperature stress in asphalt pavements is an important consideration for colder regions. In asphalt, a viscoelastic material, the developed stress depends on the trend of temperature variation and ... -
Procedure for Evaluating the Impacts of Indirect Driveway Left-Turn Treatments on Traffic Operations at Signalized Intersections
