Modeling Airport Operations Affected by a Large-Scale Disruption
(American Society of Civil Engineers, 2009)This paper deals with modeling the operations of an airport affected by a large-scale disruptive event, which in this case is considered to be the persistent heavy snowfall. Under such circumstances, the processes taking ... -
Sampling Protocol for Condition Assessment of Selected Assets
(American Society of Civil Engineers, 2009)This study addresses the development of a sampling protocol for condition assessment of selected assets in the state of Maryland. The proposed sampling protocol targets a desired precision and level of confidence in the ... -
Examining k-E Relationship of Pavement Subgrade Based on Load-Deflection Consideration
(American Society of Civil Engineers, 2009)Most rigid-pavement design methods in use today adopt the Westergaard’s approach that characterizes pavement foundation by -
Synthesis of Sign Deterioration Rates across the United States
(American Society of Civil Engineers, 2009)In response to minimum retroreflectivity standards, transportation departments are implementing sign asset management strategies, which rely upon knowledge of how retroreflectivity decreases as signs weather and age. To ... -
Right Turns on Green and Pedestrian Level of Service: Statistical Assessment
(American Society of Civil Engineers, 2009)Traditional pedestrian level of service measures at signalized intersections are based on pedestrian space and pedestrian delay. However, these measures may not adequately reflect the negative impact of right-turning traffic ... -
Discussion of “Video-Capture-Based Approach to Extract Multiple Vehicular Trajectory Data for Traffic Modeling” by Heng Wei, Chuen Feng, Eric Meyer, and Joe Lee
(American Society of Civil Engineers, 2009) -
Methodology SHAKER and the Capacity Analysis of Five Toll Plazas
(American Society of Civil Engineers, 2009)Modeling traffic at toll collection facilities can assist in computing plaza capacity and performance. It may help planners and operators decide on which lane configurations are appropriate for specific hourly approach ... -

Advances in Genetic Algorithm Optimization of Traffic Signals
(American Society of Civil Engineers, 2009)Recent advances in the optimization of fixed time traffic signals have demonstrated a move toward the use of genetic algorithm optimization with traffic network performance evaluated via stochastic microscopic simulation ... -
Validation of Perspective-View Concept for Estimating Road Horizontal Curvature
(American Society of Civil Engineers, 2009)In three-dimensional (3D) alignments, some road geometric parameters, such as vertical curve type (crest or sag), can cause drivers to have visual illusions in perceiving the horizontal curvature that may result in erroneous ... -
Finite-Element Modeling and Analysis of Reinforced Concrete Box Culverts
(American Society of Civil Engineers, 2009)There have been several controversies with regard to the true behavior of reinforced concrete box culverts in recent years. To be able to conduct a parametric study to develop design equations, a complete three-dimensional ... -
Appraisal of the Interactive Highway Safety Design Model’s Crash Prediction and Design Consistency Modules: Case Studies from Pennsylvania
(American Society of Civil Engineers, 2009)The interactive highway safety design model (IHSDM) is a suite of software analysis tools used to evaluate safety and operational effects of geometric design on two-lane rural highways. IHSDM checks existing or proposed ... -
Dynamic Tolling Strategies for Managed Lanes
(American Society of Civil Engineers, 2009)This paper proposes two sensible approaches that may be potentially implemented in practice to determine pricing strategies for operating managed toll lanes. The tolls vary dynamically in response to real-time traffic ... -
Application of Shackle’s Model and System Optimization for Highway Investment Decision Making under Uncertainty
(American Society of Civil Engineers, 2009)This paper introduces a new methodology for highway investment decision making under uncertainty that uses Shackle’s model for uncertainty-based project benefit analysis and system optimization for project selection. ... -
Finite-Element Modeling of Instrumented Flexible Pavements under Stationary Transient Loading
(American Society of Civil Engineers, 2009)Results from a finite-element program developed in the commercial code Plaxis were compared to those from an instrumented thin flexible pavement containing multiple test sections. The model has performed reasonably well ... -
Effects of Design and Site Factors on Roughness Development in Flexible Pavements
(American Society of Civil Engineers, 2009)This paper presents the relative influence of design and site factors on roughness development of in-service flexible pavements. The data from the specific pavement study (SPS)-1 experiment of the long-term pavement ... -
Disaggregate Propensity Study on Red Light Running Crashes Using Quasi-Induced Exposure Method
(American Society of Civil Engineers, 2009)Red light running (RLR) is a serious traffic hazard at signalized intersections. A number of studies have been undertaken to understand the characteristics and prevalence of highway users involved in RLR crashes. However, ... -
Modeling the Effects of Socioeconomic Factors in Highway Construction and Expansion
(American Society of Civil Engineers, 2009)The increasing commuting population often fuels the need for new highways. As the demand for new highways increases, many low-income neighborhoods are often considered for placement of new highways. While this issue has ... -
Self-Similar Characteristics of Vehicle Arrival Pattern on Highways
(American Society of Civil Engineers, 2009)This paper investigates the quantitative characteristics of the vehicle arrival pattern on highways. Inspired from a remarkable finding on data network traffic that most data packet arrival patterns follow the self-similar ... -
Cleaning Porous Pavements Using a Reverse Flush Process
(American Society of Civil Engineers, 2009)Porous pavements are asphalt or concrete pavement surfaces designed to allow moisture to flow through the surface into an underlying reservoir or into the subgrade soil. Porous pavements prevent pollutants from entering ...
