GIS-Based Network Routing Procedures for Overweight and Oversized Vehicles
(American Society of Civil Engineers, 1999)The objective of this article is to document the development of an automatic procedure for the routing of overweight vehicles with load-carrying and vertical clearance restrictions for the bridges of a highway network. The ... -
Performance of Automatic ANN-Based Incident Detection on Freeways
(American Society of Civil Engineers, 1999)Automatic incident detection on freeways is an essential ingredient for the successful deployment of Intelligent Transportation Systems. Several incident detection algorithms have been developed in the past three decades; ... -
Structural Response of LVR Flexible Pavements at Mn/Road Project
(American Society of Civil Engineers, 1999)Pavement surface deflection basins provide valuable information for the structural evaluation of flexible pavements. Surface deflection measurements are rapid, inexpensive, and nondestructive and are used frequently as an ... -
Reversing Direction of Transportation Planning Process
(American Society of Civil Engineers, 1999)The process of transportation planning begins with an assumed land use and then projects future traffic volumes. To determine land-use limitations as a function of the capacity of the transportation system, we reversed the ... -
Approximate Perspective Design of Roads
(American Society of Civil Engineers, 1999)Coordination of horizontal and vertical alignments is an important principle in road geometric design, and it should begin with preliminary design. Perspective drawings and sketches are considered to be effective means for ... -
Measuring Control Delay at Signalized Intersections
(American Society of Civil Engineers, 1999)This paper presents a new methodology to measure delay at signalized intersections using linearly referenced global positioning system data. The methodology can be used to evaluate new models that estimate control delay ... -
Automated Calculation of Sight Distance from Horizontal Geometry
(American Society of Civil Engineers, 1999)This paper describes a method for automatic calculation of sight distance, subject only to constraints of horizontal geometry, along an arbitrary alignment of tangent sections, circular curves, and spiral transition curves. ... -
Surface Roughness Effect on Dynamic Response of Pavements
(American Society of Civil Engineers, 1999)By modeling a pavement structure as a beam rested on a viscoelastic foundation, we have constructed a physical picture linking together vehicle dynamics, road profile characteristics, and pavement response in a theoretical ... -
Hybrid Delay Models for Unsaturated Two-Way Stop Controlled Intersections
(American Society of Civil Engineers, 1999)A new methodology for modeling delay at undersaturated two-way stop controlled intersections was developed. Total delay was divided into service delay and queue delay. Empirical models were developed to estimate service ... -

Effect of Transverse Shear on Edge Stresses in Rigid Pavements
(American Society of Civil Engineers, 1999)The classical Westergaard idealization of the rigid pavement system assumes that the slab-on-grade can be modeled as a thin elastic plate on a bed of springs. Implicit in this assumption is the Kirchhoff (or thin) plate ... -
Modeling of Urban Area Stop-and-Go Traffic Noise
(American Society of Civil Engineers, 1999)Simulation of urban traffic noise along with a mathematical model of stop-and-go traffic noise for the road network in the city center is presented in this paper. The road network of the central part of Bangkok surrounded ... -
Urban Street Speed Related to Width and Functional Class
(American Society of Civil Engineers, 1999)In recent years, land development professionals from various disciplines have advocated narrowing city streets as a means to slow speeds and improve the urban environment. This paper reports the findings of a study of ... -
Opportunity Cost-Based Models for Traffic Incident Response Problems
(American Society of Civil Engineers, 1999)Real-time traffic incident response strategies deal with the determination of optimal resource allocation policies in response to traffic incidents occurring on a network. Such strategies also should address the effect of ... -
Gap Acceptance at Atypical Stop-Controlled Intersections
(American Society of Civil Engineers, 1999)A gap acceptance study was performed at a T-intersection at which left-turn traffic on the through leg had the right-of-way. A number of methods were used to model the critical gap size at this atypical intersection. The ... -
Modeling Level of Urban Taxi Services Using Neural Network
(American Society of Civil Engineers, 1999)This paper is concerned with the modeling of the complex demand-supply relationship in urban taxi services. A neural network model is developed, based on a taxi service situation observed in the urban area of Hong Kong. ... -
Numerical Simulation of Rolling Dynamic Deflectometer Tests
(American Society of Civil Engineers, 1999)The responses of typical flexible and rigid pavements to the dynamic loads imposed by the rolling dynamic deflectometer (RDD) were investigated. The RDD is a recently developed nondestructive testing vehicle that applies ... -
Multicriteria Framework to Aid Comparison of Roadway Improvement Projects
(American Society of Civil Engineers, 1999)A multicriteria decision-making framework to aid the selection of roadway improvement projects is developed, based on the needs of a state highway agency. Three major factors—crash-risk reduction, performance improvement, ... -
Automated Highways: Effects on Travel, Emissions, and Traveler Welfare
(American Society of Civil Engineers, 1999)A recent project simulating automated freeways in the Sacramento, Calif., region is described. Of special interest is the economic welfare model applied in this project. It was found that travel and emissions increase with ... -
Economic Evaluation of Signal Preemption Projects
(American Society of Civil Engineers, 1999)Preemption techniques are designed to provide preferential treatments to buses at signalized intersections. A preemption strategy, if properly designed, can provide continuous green phases to buses at successive intersections, ...
