Estimation of Delay Induced by Downstream Operations at Signalized Intersections over Extended Control Time
(American Society of Civil Engineers, 2013)Analytical macroscopic models are presented to quantify delay at signalized intersections for extended control periods (multiple cycles) attributable to downstream time-variable congestion. Each of the models consists of ... -
Framework for Multiobjective Optimization of Physical Highway Assets Investments
(American Society of Civil Engineers, 2012)Optimization-based tools have been included in many engineering management systems for individual infrastructure asset classes such as pavement management systems (PMS) and bridge management systems (BMS). These tools ... -
Environmental Life-Cycle Assessment of Winter Maintenance Treatments for Roadways
(American Society of Civil Engineers, 2013)Departments of Transportation (DOTs) rely heavily on chloride-based treatments for winter road maintenance despite the well-documented effects of these chemicals on infrastructure and the environment. Proposed alternative ... -
Effect of Pavement Type on Overlay Roughness Progression
(American Society of Civil Engineers, 2012)This paper investigates the impact of overlay type (asphalt and concrete) on the progression of pavement roughness as described by the international roughness index (IRI). Pavement roughness is defined as deformities or ... -
Passenger Assignment Model Based on Common Route in Congested Transit Networks
(American Society of Civil Engineers, 2012)In this paper, the common line problem and passengers’ choice behaviors in transit networks are revisited and discussed. The concept of the common line problem is extended to represent a common route problem in transit ... -
Deriving Traffic Flow Patterns from Historical Data
(American Society of Civil Engineers, 2012)The development and decreased cost of technology and communications have brought about a huge increase in the availability of traffic data. With every passing day, traffic management centers must deal with an increased ... -
Cellular Automaton Modeling of the Interaction between Vehicles and Pedestrians at Signalized Crosswalk
(American Society of Civil Engineers, 2012)Characteristics of mixed traffic on a road with a signalized crosswalk are investigated by cellular automaton modeling. The interaction mechanism between vehicles and pedestrians is taken into account. Also, the inordinate ... -
Application of Soft Computing for Prediction of Pavement Condition Index
(American Society of Civil Engineers, 2012)The pavement condition index (PCI) is a widely used numerical index for the evaluation of the structural integrity and operational condition of pavements. Estimation of the PCI is based on the results of a visual inspection ... -
Is the Road Quality Still Better?
(American Society of Civil Engineers, 2012)This study quantifies and explains the paradox of a slow increase in road quality over time with a concomitant decrease in ride comfort or objective road quality. The study estimates the effect of road profile wavelength ... -
Methodology for Pavement Design Reliability and Back Analysis Using Markov Chain Monte Carlo Simulation
(American Society of Civil Engineers, 2013)Given the increasing cost of designing and building new highway pavements, reliability analysis has become vital to ensure that a given pavement performs as expected in the field. Recognizing the importance of failure ... -
Understanding the Dynamics of Heavy Vehicle Interactions in Car-Following
(American Society of Civil Engineers, 2012)Heavy vehicles and passenger cars differ in their maneuverability and acceleration capabilities. Heavy vehicles thus influence other traffic in a different manner than passenger vehicles, causing different levels of traffic ... -
Train Routing Model and Algorithm Combined with Train Scheduling
(American Society of Civil Engineers, 2013)This paper constructs a train routing model combined with a train scheduling problem, which is a 0–1 mixed-integer nonlinear programming problem. Except for train route choice, the model considers a system of complicated ... -
Optimizing Longitudinal Alignment in Railway with Regard to Construction and Operating Costs
(American Society of Civil Engineers, 2012)Designing baseline or vertical alignment in railways greatly depends on the designer’s experience. An inaccurate design imposes unreasonable costs during construction and operations. This paper presents a program to find ... -
Standard Pedestrian Equivalent Factors: New Approach to Analyzing Pedestrian Flow
(American Society of Civil Engineers, 2013)The design and planning of pedestrian walking facilities must be undertaken in the context of the prevailing and future local traffic composition. The latter is changing rapidly as a result of demographic changes such as ... -
Development of a Predictive System for Estimating Fatigue Life of Asphalt Mixtures Using the Indirect Tensile Test
(American Society of Civil Engineers, 2012)Fatigue cracking is a major problem in asphalt pavement. It would be beneficial for predictions of the fatigue life of asphalt mixtures to be made with minimal effort and time, both at the design stage and the operating ... -
Continuous Approximation Model for the Vehicle Routing Problem for Emissions Minimization at the Strategic Level
