Heavy Load, Low Tire Pressure Rutting of Unbound Granular Pavements
(American Society of Civil Engineers, 1997)In a study of effects of wheels with very heavy loads but very low tire inflation pressures on unbound, single-layer granular pavements, trafficking tests were carried out on full-scale indoor pavements at the Pavement ... -
Performance of Safety Evaluation Methods
(American Society of Civil Engineers, 1997)The main objective of this study was to investigate the performance of safety evaluation methods and estimate the safety effectiveness of street bumps, closing of median openings, and divisional islands in an urban ... -
Highway Maintenance Fund Allocation: Tabulated Manual Procedure
(American Society of Civil Engineers, 1997)Several variables are usually considered when fund is allocated for highway improvement programs. Among these variables are the project improvement alternatives for each highway, the different locations available, and the ... -
New Transition Curve Joining Two Straight Lines
(American Society of Civil Engineers, 1997)In this paper, a new transition curve to be used in the design of the horizontal geometry of routes has been examined. This curve joins two straight lines with a single element. It is an alternative curve to the well-known ... -
Determining Need for and Location of Truck Escape RAMPS
(American Society of Civil Engineers, 1997)The main objective of this paper is to introduce a systematic approach to determine the need for and location of truck escape ramps (TERs). The approach utilizes variables concerning the design vehicle, the road, and the ... -
Intelligent Traffic Data Processing for ITS Applications
(American Society of Civil Engineers, 1997)Real-time traffic data are the lifeline sustaining the operation of Advanced Traffic Management and Advanced Traveler Information Systems (ATMS/ATIS). Data are essential to drive algorithms related to congestion/incident ... -
Toward an Evaluation Framework for Road Pricing
(American Society of Civil Engineers, 1997)Recent advances in road pricing technology and the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991, which authorized $25,000,000 to fund congestion pricing demonstration projects, have created a resurgence ... -
Simulation Laboratory for Evaluating Dynamic Traffic Management Systems
(American Society of Civil Engineers, 1997)This paper presents a simulation laboratory for performance evaluation and design refinement of dynamic traffic management systems. The laboratory consists of four integrated components: (1) a traffic management simulator, ... -
Frequency of Probe Reports and Variance of Travel Time Estimates
(American Society of Civil Engineers, 1997)An important design issue relating to probe-based Advanced Traveler Information Systems (ATISs) and Advanced Traffic Management systems is the sample size of probes (or the number of link traversals by probe vehicles) per ... -
New Model for Predicting Freeway Incidents and Incident Delays
(American Society of Civil Engineers, 1997)This paper presents a new model that predicts the number of freeway incidents and associated delays based on general freeway segment characteristics, traffic volumes, and incident management procedures. The model is intended ... -
Turning Movement Estimation in Real Time
(American Society of Civil Engineers, 1997)Fast processors offer exciting opportunities for real-time traffic monitoring. Conventional transportation planning models that assume stable and predictable travel patterns do not lend themselves to on-line traffic ... -
Dynamic Route Choice Model of Large-Scale Traffic Network
(American Society of Civil Engineers, 1997)Application and extensions of a dynamic network equilibrium model to the Advanced Driver and Vehicle Advisory Navigation Concept (ADVANCE) Network are described in this paper. ADVANCE is a dynamic route guidance field test ... -
Predicting Traffic-Generated Carbon Dioxide Concentrations in Sydney
(American Society of Civil Engineers, 1997)The abilities of two line-source dispersion models to predict road-edge concentrations of carbon dioxide along several roads are tested. The comparison of the predicted CO -
