Modeling and Forecasting Vehicular Traffic Flow as a Seasonal ARIMA Process: Theoretical Basis and Empirical Results
(American Society of Civil Engineers, 2003)This article presents the theoretical basis for modeling univariate traffic condition data streams as seasonal autoregressive integrated moving average processes. This foundation rests on the Wold decomposition theorem and ... -
Measures of Short-Term Effectiveness of Highway Pavement Maintenance
(American Society of Civil Engineers, 2003)Selecting an appropriate measure of short term maintenance effectiveness and determining its value constitute the first in a three-step process for evaluating maintenance effectiveness in the short term. The second and ... -
Performance Evaluation of Signalized Urban Intersections under Mixed Traffic Conditions by Gray System Theory
(American Society of Civil Engineers, 2004)This paper presents a gray system theory-based method for the quantitative evaluation and ranking of the operational and safety performance of signalized intersections in urban areas under mixed traffic conditions. Mixed ... -
Reappraisal of Marston’s Formula
(American Society of Civil Engineers, 2003)A review of the genesis of Marston’s theory for soil loading of pipe in trenches found that the almost 90-year-old theory contains various flaws, including assumptions about lateral pressures and shear strengths that can ... -
Exploratory Spatial Analysis of Expressway Ramps and its Effect on Route Choice
(American Society of Civil Engineers, 2004)This research is based on the analysis of an origin-destination survey of users of Central Florida’s expressway system. It presents an initial investigation of the drivers’ choice in accessing/exiting the ramps of the ... -
Impacts of Red Light Camera on Violation Characteristics
(American Society of Civil Engineers, 2003)This paper presents the findings of a before-and-after study which evaluated the impacts of installing and operating red light cameras (RLC) at two “T” and one “X” signalized intersections. The red running violations and ... -
Using Fuzzy Clustering of User Perception to Define Levels of Service at Signalized Intersections
(American Society of Civil Engineers, 2003)In the current -
Performance Comparison of Automatic Vehicle Identification and Inductive Loop Traffic Detectors for Incident Detection
(American Society of Civil Engineers, 2003)TransGuide is San Antonio’s multifunctional citywide center that manages traffic through surveillance, incident detection/management, and dissemination of traffic information. This paper reviews automatic incident detection ... -
Dynamic Travel Time Prediction with Real-Time and Historic Data
(American Society of Civil Engineers, 2003)Travel time prediction has been an interesting research area for decades during which various prediction models have been developed. This paper discusses the results and accuracy generated by different prediction models ... -
Application of System Dynamics in Car-Following Models
(American Society of Civil Engineers, 2003)Over the past 50 years, many different “car-following” models have been proposed to describe driver behavior in a traffic stream. A number of inherent assumptions about human constraints and preferences in existing ... -
Evaluation of Value Pricing Using a Multiclass Dynamic Network Model
(American Society of Civil Engineers, 2003)To convert HOV (high-occupancy vehicle) lanes to HOT (high-occupancy toll) lanes, it is necessary to evaluate the relevant benefits to drivers, to highway maintenance, to traffic management, and to the whole society under ... -
Analytical Model to Determine the Influence of Horizontal Alignment of Two-Axle Heavy Vehicles on Upgrades
(American Society of Civil Engineers, 2003)Existing design policies determine the speed variation of vehicles on upgrades solely as a function of specific values: initial speed, grade, and weight to power ratio. This paper establishes a dynamic model that considers ... -
Evaluating a Detection and Warning System to Deter No-Passing Zone Violations
(American Society of Civil Engineers, 2003)Evaluating the performance of a detection and warning system designed specifically to detect and warn no-passing zone violations on vertical curves of two-lane rural roads is the focus of this paper. The evaluation is ... -
Incremental Nonlinear Model for Predicting Pavement Serviceability
(American Society of Civil Engineers, 2003)A recursive nonlinear model was developed for the prediction of pavement performance as a function of traffic characteristics, pavement structural properties, and environmental conditions. The model highlights some of the ... -
Simulating the Impacts of Strong Bus Priority Measures
(American Society of Civil Engineers, 2003)Policies to reduce levels of traffic congestion and pollution in major urban areas often focus strongly on the concept of a sustainable transport system, but to achieve this vision a significant modal shift from private ... -
Use of the Asphalt Pavement Analyzer and Repeated Simple Shear Test at Constant Height to Augment Superpave Volumetric Mix Design
(American Society of Civil Engineers, 2003)As accelerated pavement testing (APT) devices emerge as possible candidates for a supplemental performance test, questions related to the ability to assess resistance of hot mix asphalt to permanent deformation under ... -
Optimum Compaction Temperature for Modified Binders
(American Society of Civil Engineers, 2003)With increasing use of modified asphalt binders, the correct compaction temperature range for asphalt mixtures containing these binders needs to be determined. The current procedure uses asphalt binder viscosities to ... -
Analysis of Fiber Optic Traffic Sensors in Flexible Pavements
(American Society of Civil Engineers, 2003)A series of linear-elastic plane-strain finite-element analyses were conducted on a newly developed fiber optic traffic sensor whose potential uses include traffic classification and weigh-in-motion. These sensors have ... -
Factors Influencing the Strength of Cement Fly Ash Base Courses
(American Society of Civil Engineers, 2003)Fly ash is a waste produced in coal-fired thermal power stations. It has pozzolonic properties and can therefore be stabilized with either cement or lime to achieve the strength required for use as base courses in pavements. ... -
