Cross Tensioned Concrete Pavement
(American Society of Civil Engineers, 2003)The deterioration of Portland cement concrete pavement is most often due to intrusion of water into the pavement system as well as due to inferior performance of the transverse joints. The infiltration of surface runoff ... -
Pavement Response and Rutting for Full-Scale and Scaled APT
(American Society of Civil Engineers, 2003)A new accelerated pavement testing (APT) tool has recently been developed between relatively inexpensive laboratory testing and expensive but more realistic full-scale accelerated load testing. The one-third scale model ... -
Impact of Dynamic and Safety-Conscious Route Guidance on Accident Risk
(American Society of Civil Engineers, 2003)Under intelligent transportation systems, dynamic route guidance systems (DRG) provide routing information to motorists based on current traffic conditions on a network. Not enough attention, however, has been given to the ... -
Application of Variable Tolls on Congested Toll Road
(American Society of Civil Engineers, 2003)This paper examines how different price elasticities of travel demand would impact traffic on a toll road with a time-of-day variable toll rate. Price elasticities were derived from data collected on a pair of bridges that ... -
Examining Sensitivity of Impact of Taxi Traffic on Capacity and Delays at Urban Road Sections
(American Society of Civil Engineers, 2003)This paper examines the influence of taxi behavior on urban traffic conditions. Using computer simulation and the Taxi Equivalence Factor (TEF), a concept similar to the passenger car equivalents for heavy vehicles, the ... -
Reinforcement Learning for <i>True</i> Adaptive Traffic Signal Control
(American Society of Civil Engineers, 2003)The ability to exert -
Estimating Total Distance for Hauling Import and Export Containers
(American Society of Civil Engineers, 2003)This paper introduces a planning model to estimate the total distance traveled by prime movers in transporting import and export containers between a port, warehouses, and container yards. The total distance includes the ... -
Statistical Approach to Road Segmentation
(American Society of Civil Engineers, 2003)A method for segmentation of a road based on surface measurements is presented. This method is based on a statistical model of the measurement series and acknowledges that neighboring measurements are dependent. Sudden ... -
Finite-Element Modeling of Skid Resistance Test
(American Society of Civil Engineers, 2003)The British pendulum test is one of the most common laboratory test methods for the determination of low-speed microtexture-related skid resistance properties of pavement surface materials. This paper presents the development ... -
Clogging Evaluation of Permeable Bases
(American Society of Civil Engineers, 2003)The clogging of the void spaces within the permeable base by foreign particles can severely reduce its drainage capacity. This will, in turn, reduce the service life of the permeable base layer within the pavement. In this ... -
Comparative Analysis of Using AASHTO and WESDEF Approaches in Back-calculation of Pavement Layer Moduli
(American Society of Civil Engineers, 2003)This paper presents an evaluation of the falling weight deflectometer testing data using the AASHTO and WESDEF back-calculation procedures. General concepts of each procedure are highlighted, together with data utilized ... -
Sustainability and Urban Public Transportation
(American Society of Civil Engineers, 2003)An analysis of data of the past few decades from cities around the world indicates that history is repeating itself. Although there are significant differences in socioeconomic and technological characteristics among these ... -
Relationships Among Urban Freeway Accidents, Traffic Flow, Weather, and Lighting Conditions
(American Society of Civil Engineers, 2003)Linear and nonlinear multivariate statistical analyses are applied to determine how the types of accidents that occur on heavily used freeways in Southern California are related both to the flow of traffic and to weather ... -
Characterization of Freeway Capacity Reduction Resulting from Traffic Accidents
(American Society of Civil Engineers, 2003)Incidents, defined as unplanned events that temporarily reduce roadway capacity, contribute significantly to urban freeway congestion. Transportation agencies have developed incident management programs in order to support ... -
Review of <i>Advanced Traveler Information Systems</i> by Steve McQueen, Rick Schuman, and Kan Chen

Levels of Service for Stairway in Hong Kong Underground Stations
(American Society of Civil Engineers, 2003)Safe pedestrian movement is essential in all cities, but particularly in such densely populated cities as Hong Kong. This paper aims to investigate the levels of service (LOS) for stairways in Hong Kong Mass Transit Railway ... -
Airport Choice, Leakage, and Experience in Single-Airport Regions
(American Society of Civil Engineers, 2003)Airport leakage refers to the phenomenon where travelers in small, single-airport regions avoid using their local (nearest) airports and prefer to use the more distant but larger metropolitan airports. Past studies of ... -
Proof and Comments on Extensively Used Assumption in PCC Pavement Analysis and Evaluation
(American Society of Civil Engineers, 2003)Load transfer in rigid pavements needs to be appropriately considered for portland cement concrete (PCC) pavement analysis and evaluation. One assumption has been extensively used: that the sum of deflections on two sides ... -
Highway-Rail Quad Gate Operation Time by System Simulation of Dynamic Dilemma Zone
(American Society of Civil Engineers, 2003)A simulation model incorporating determination of a dynamic dilemma zone and algorithms to determine gate operation parameters for train-vehicle collision avoidance at highway-rail intersections (HRI) is developed, validated, ... -
Hot Spot Management Benefits: Robustness Analysis for a Congested Developing City
(American Society of Civil Engineers, 2003)This paper focuses on evaluating the role intelligent transportation systems (ITS) are likely to play in alleviating traffic congestion in a developing congested city. Hot Spot Management (HSM) is selected as the ITS ...
