Estimation of Highway Maintenance Marginal Cost under Multiple Maintenance Activities
(American Society of Civil Engineers, 2010)This paper focuses on the estimation of highway maintenance marginal costs. Highway maintenance marginal cost has been estimated in the literature using the perpetual overlay indirect approach. This approach assumes that ... -
Stress-Prediction Model for Airport Pavements with Jointed Concrete Slabs
(American Society of Civil Engineers, 2010)Two specific three-dimensional finite-element models are presented for making an evaluation of the maximum stresses at critical locations in concrete slabs (i.e., at the interior and edge) that is superior to the classic ... -
Assessment of Link Reliability as a Function of Congestion Components
(American Society of Civil Engineers, 2010)Travelers’ perception of reliability of a road network is typically based on factors contributing to both recurring and nonrecurring congestion. However, literature documents little research to integrate, estimate and ... -
Speed Prediction Models for Multilane Highways: Simultaneous Equations Approach
(American Society of Civil Engineers, 2010)Past speed-related research has focused on the operational effects of roadway geometrics along rural two-lane highways using ordinary least-squares regression models. More recent research has focused on the association of ... -
Microscopic Traffic Simulation Approach to the Capacity Impact Analysis of Weaving Sections for the Exclusive Bus Lanes on an Urban Expressway
(American Society of Civil Engineers, 2010)This paper presents a microscopic traffic simulation approach to the capacity impact analysis of weaving sections caused by the installation of exclusive bus lanes (XBLs) on urban expressways. Three typical configurations ... -
Perceived Level of Service, Driver, and Traffic Characteristics: Piecewise Linear Model
(American Society of Civil Engineers, 2010)The objective of this research is the analysis of perceived highway level of service in relation to drivers’ personal characteristics and traffic conditions. A field survey was carried out for that purpose, in which drivers ... -
Car-Following Interaction and the Definition of Free-Moving Vehicles on Two-Lane Rural Highways
(American Society of Civil Engineers, 2010)This paper presents an investigation into car-following interactions on two-lane rural highways. Empirical data from several study sites on two-lane and four-lane rural highways in the state of Montana were used in this ... -
Modeling Road Traffic Demand of Container Consolidation in a Chinese Port Terminal
(American Society of Civil Engineers, 2010)This paper models road traffic demand of container trucks in a Chinese container port. The model is helpful for road planning and traffic management in the port. First, we analyze the attributes of road traffic in the port, ... -
Web-Based Advanced Traveler Information System for Developing Countries
(American Society of Civil Engineers, 2010)Advanced traveler information systems (ATISs) are continuously becoming key intelligent transportation system for disseminating valuable traveler information such as traffic, incident, and transit information. Developed ... -
Horizontal Curve Accident Modification Factor with Consideration of Driveway Density on Rural Four-Lane Highways in Texas
(American Society of Civil Engineers, 2010)Agencies are seeking a better understanding of those roadway or roadside features that affect safety. The objectives of this study were to develop a horizontal curve accident modification factor (AMF) for rural four-lane ... -
Modeling Destination Choice Behavior Incorporating Spatial Factors, Individual Sociodemographics, and Travel Mode
(American Society of Civil Engineers, 2010)Destination choice studies have been primarily carried out in developed countries. However in China, a typical developing country, few studies about destination choice exist. In this paper, we propose nonlinear-in-parameters ... -
Assessing the Agreement among Pavement Condition Indexes
(American Society of Civil Engineers, 2010)Pavement condition indexes are numerical indicators of the structural and material integrity of a pavement. Because these indexes appear to be similar (essentially a 0–100 scale, with 100 indicating ideal condition), it ... -
Aerodynamic Effects Caused by Trains Entering Tunnels
(American Society of Civil Engineers, 2010)With the increase in train speed, the aerodynamics in tunnels is emerging. In recent years, we have carried out a few full-scale tests about tunnel aerodynamics, and the law of influence of train speed on pressure change, ... -
Travelers’ Response to Value Pricing: Application of Departure Time Choices to TRANSIMS
(American Society of Civil Engineers, 2010)There is a lack of proper travel demand forecasting tools that can evaluate and determine the impacts of pricing on travelers’ decision. The current methods use aggregated and zonal-based approaches that lack the capability ... -
Impact of Bead Density on Paint Pavement Marking Retroreflectivity
(American Society of Civil Engineers, 2010)This paper addresses the impact of bead density on paint pavement marking retroreflectivity. The writers collected retroreflectivity data and glass bead images on 40 segments of two-lane highways. Bead density is defined ... -
Road Roughness and Whole Body Vibration: Evaluation Tools and Comfort Limits
(American Society of Civil Engineers, 2010)An important element of achieving quality in a road network is the control of vehicle vibration due to pavement roughness and road irregularities. Scientific literature and international standards suggest that we evaluate ... -
Neural Network–Swarm Intelligence Hybrid Nonlinear Optimization Algorithm for Pavement Moduli Back-Calculation
(American Society of Civil Engineers, 2010)This paper describes a novel hybrid intelligent system approach to inversion of nondestructive pavement deflection data and back-calculation of nonlinear stress-dependent pavement layer moduli. Particle swarm optimization ... -
Bus-to-Depot Allocation: Models and Decision Support System
(American Society of Civil Engineers, 2010)Reducing the cost of operations is one of the most important considerations for urban transport systems. Deadhead kilometer costs are an important aspect of operating costs and are associated with buses traveling empty to ... -
Simulation-Based Secondary Incident Filtering Method
(American Society of Civil Engineers, 2010)A significant portion of nonrecurrent freeway congestion is caused by incidents. This nonrecurrent congestion negatively impacts safety and mobility. It produces enormous travel delay and results in secondary incidents, ... -
