Alternative Approach to Estimation of Critical Cornering Speed
(American Society of Civil Engineers, 1994)An alternative approach to the estimation of the critical cornering speed of large combination vehicles is presented. Existing techniques are based on analytical models subject to a series of simplifying assumptions, and ... -
Discussion of “<i>Geometric Characterization of Road Humps for Speed‐Control Design</i>” by T. F. Fwa and L. S. Tan (July/August, 1992, Vol. 118, No. 4)

(American Society of Civil Engineers, 1994) -
Comparison of Traditional and Neural Classifiers for Pavement‐Crack Detection
(American Society of Civil Engineers, 1994)This paper presents a comparative evaluation of traditional and neural‐network classifiers to detect cracks in video images of asphalt‐concrete pavement surfaces. The traditional classifiers used are the Bayes classifier and the -
Erratum:
(American Society of Civil Engineers, 1994) -
Optimum Design of Airport Enplaning Curbside Areas
(American Society of Civil Engineers, 1994)A new approach for design of enplaning curbside areas at airports incorporating the users' behavior was investigated. A design procedure based on the vehicular demand distribution over the doors of terminal building and ... -
Model to Estimate Highway Earthwork Cost in Nepal
(American Society of Civil Engineers, 1994)In a developing country like Nepal, where in most cases projects are externally financed, the minimization of construction costs is the most important factor in a highway project. But the cost estimates to be used at the ... -
Estimation of Pavement‐Layer Moduli using Nonlinear Optimization Technique
(American Society of Civil Engineers, 1994)Falling Weight Deflectometer (FWD) testing is used for nondestructive structural evaluation of existing pavements. The deflection data from FWD can be used for estimation of layer moduli by an iterative technique. In the ... -
Severity Measures in Side‐Impacts with Narrow Roadside Structures
(American Society of Civil Engineers, 1994)Vehicles that run off the road and then slide sideways into fixed objects along the roadside are an important accident scenario that has been often overlooked in developing roadside hardware. This paper combines the results ... -
Spalling of Continuously Reinforced Concrete Pavements
(American Society of Civil Engineers, 1994)Field investigation of continuously reinforced concrete pavements indicate the presence of delaminations at a depth of approximately 2.5 cm (1 in.) below the concrete pavement slab surface. These delaminations originate ... -
Probabilistic Behavior of Pavements
(American Society of Civil Engineers, 1994)Since the AASHO road test of 1962, tremendous efforts have been devoted to improve the methodologies of pavement performance prediction. The successful implementation of the Network Optimization System (NOS) in the Arizona ... -
Simple Procedure for Identifying Pavement Distresses from Video Images
(American Society of Civil Engineers, 1994)Pavement distress information is important to highway engineers in managing pavement networks. At the present time, there are several research groups working to develop a more efficient and unbiased method of obtaining ... -
Neural Network for Gap Acceptance at Stop‐Controlled Intersections
(American Society of Civil Engineers, 1994)The behavior of gap acceptance by vehicles at intersections with stop signs involves the complex interaction of numerous geometric, traffic, and environmental factors. Several methods, including empirical analysis, and ... -
Evaluation Framework for IVHS
(American Society of Civil Engineers, 1994)Evaluation is recognized as a key and integral element of the joint national effort of intelligent‐vehicle highway systems (IVHS) research, development, and deployment. It is expected to play an important role in assessing ... -
Advanced Continuum Traffic Flow Models for Congested Freeways
(American Society of Civil Engineers, 1994)Advanced traffic management, simulation, and control schemes require reasonably accurate descriptions of flow dynamics especially at congested conditions. Two new high‐order continuum traffic flow formulations are developed ... -
New Methodology for Modeling Annual‐Aircraft Emissions at Airports
(American Society of Civil Engineers, 1994)An as‐accurate‐as‐possible estimation of total‐aircraft emissions are an essential component of any environmental‐impact assessment done for proposed expansions at major airports. To determine the amount of emissions ... -
Interface Shear Stress in Overlaid Concrete Pavements
(American Society of Civil Engineers, 1994)Shear stresses at the interface between an existing concrete pavement and an overlay are calculated using the finite‐element method for different loading conditions. The effects of vertical wheel loads, temperature loading, ... -
New Crack‐Imaging Procedure Using Spatial Autocorrelation Function
(American Society of Civil Engineers, 1994)An innovative method of applying a spatial autocorrelation function to analyze pavement image data is presented in this paper. One of the major advantages of using a spatial autocorrelation function is its capability of ... -
Evaluating Roadside Hazards Using Computer‐Simulation Model
(American Society of Civil Engineers, 1994)The ability to accurately evaluate roadside hazards is very important to highway safety officials and researchers, who are concerned with reducing the frequency, severity, and ultimately, the cost of “run‐off‐the‐road” ... -
Asphalt Portland Cement Concrete Composite: Laboratory Evaluation
(American Society of Civil Engineers, 1994)The lack of strain characteristics of rigid pavements and bridge deck overlays and the susceptibility of flexible pavements and hot‐mix asphalt overlays to abrasion wear, fuel spillage, and stripping suggests the search ...
