Evaluating Speed Differences Between Cars, Light-Duty Trucks, and Vans for Emissions Modeling
(American Society of Civil Engineers, 2004)The percentage of sport-utility vehicles, light-duty trucks, and passenger vans in the on-road light-duty fleet is steadily increasing. The implications for modeling emissions from on-road vehicles are significant since ... -
Sensitivity Analysis of Transit Signal Priority Impacts on Operation of a Signalized Intersection
(American Society of Civil Engineers, 2004)The study consists of a systematic simulation evaluation of transit signal priority (TSP) impacts on the operations of a single signalized intersection within a coordinated arterial system. The study demonstrates first ... -
Effective Approach to Improve Pavement Drainage Layers
(American Society of Civil Engineers, 2004)The objective of this study was twofold: (1) quantify the benefits of a specially designed geocomposite membrane [a low modulus polyvinyl chloride (PVC) layer sandwiched between two nonwoven geotextiles] to act as a moisture ... -
Wireless Location Technology-Based Traffic Monitoring: Critical Assessment and Evaluation of an Early-Generation System
(American Society of Civil Engineers, 2004)An emerging technology known as wireless location technology has been developed to allow mobile wireless devices (the most common of which are cellular telephones) to be geolocated. Over the past decade, a number of research ... -
Pavement Design Model for Unbound Granular Materials
(American Society of Civil Engineers, 2004)The paper reports the results of several repeated load triaxial tests performed on a crushed rock aggregate at different stress levels. The development of the resulting permanent deformation that accumulates with the ... -
Geometric Modeling of Highways Using Global Positioning System Data and <i>B</i>-Spline Approximation
(American Society of Civil Engineers, 2004)The proliferation and increased precision of global positioning system (GPS) devices enable the technology to be used in new and innovative applications. In the past few years, the Kansas Department of Transportation ... -
New Optimal Cycle Length Formulation for Pretimed Signals at Isolated Intersections
(American Society of Civil Engineers, 2004)Under near-saturated or saturated conditions, the optimal cycle length formulation proposed by Webster becomes infeasible because (1) it generates an unreasonably large cycle length as the intersection critical flow ratio ... -
Traffic Adaptive Control for Oversaturated Isolated Intersections: Model Development and Simulation Testing
(American Society of Civil Engineers, 2004)Traffic adaptive control for oversaturated intersections (TACOS) is a hybrid optimization and rule-based strategy that addresses weaknesses of existing adaptive control strategies by having attributes such as: (1) the ... -
Radius Requirements for Reverse Horizontal Curves on Three-Dimensional Alignments
(American Society of Civil Engineers, 2004)Horizontal reverse curves are used in all types of highways either in mainline alignments or in freeway interchange ramps. At present, minimum radius requirements for reverse curves are determined based on vehicle performance ... -
Model to Evaluate Potential Accident Rate at Roundabouts
(American Society of Civil Engineers, 2004)The increasing use of roundabouts for plane junctions calls for an evaluation of the potential accident rate for this kind of intersection. This gives a further element for the choice between alternative typologies of ... -
Developing an Automated Procedure for Extraction of Road Data from High-Resolution Satellite Images for Geospatial Information Systems
(American Society of Civil Engineers, 2004)There is a growing need for automated procedures that can update road databases in Geospatial Information Systems (GIS). Such procedures are in a great demand when the GIS database needs to be updated very frequently and ... -
Rutting Prediction of Asphalt Pavement Layer Using C-ϕ Model
(American Society of Civil Engineers, 2004)Past research has shown that the concept of -

Assessing the Occlusion Effect of Large-Dimension Vehicles on Traffic Signs at Multilane Highways
(American Society of Civil Engineers, 2004)This paper presents an investigation into the different factors that affect sign occlusion by large-dimension vehicles on multilane highway facilities. Parametric analyses were conducted to explore these effects using a ... -
Large-Scale Dynamic Traffic Assignment: Implementation Issues and Computational Analysis
(American Society of Civil Engineers, 2004)This paper is concerned with implementation challenges related to using dynamic traffic assignment on actual large urban networks. Such challenges include the manipulation of network and demand data, the modeling of turning ... -
ARO: Geographic Information Systems-Based System for Optimizing Airport Runway Orientation
(American Society of Civil Engineers, 2004)Determination of a runway orientation is a critical task in the planning and design of an airport. The direction of the runway controls the layout of the other airport facilities, such as passenger terminals, taxiways/apron ... -
Control Strategies for Oversaturated Traffic
(American Society of Civil Engineers, 2004)Recently, a dynamic traffic control system designated as dynamic intersection signal control optimization (DISCO) has been developed. DISCO considers the entire fundamental diagram of traffic flow, which is essential for ... -
Development of a Mechanistic-Empirical Model to Characterize Rutting in Flexible Pavements
(American Society of Civil Engineers, 2004)Dramatic increases in the number and weight of vehicles have resulted in severe rutting on highways in Taiwan. The Taiwan Area National Freeway Bureau constructed an in-service test road in 1996 to investigate the effect ... -
Pollution Intrusion on Soil-Pavement System
(American Society of Civil Engineers, 2004)The performance of both flexible and rigid pavement is a function of the constituent materials and their susceptibility to physical and chemical stress and degradation. To that end, specific phenomena that accompany and ... -
Road Network Robustness for Avoiding Functional Isolation in Disasters
