Discussion of “<i>Warping Stresses in Concrete Pavements on Pasternak Foundation</i>” by X. P. Shi, T. F. Fwa, and S. A. Tan (November/December, 1993, Vol. 119, No. 6)
(American Society of Civil Engineers, 1994) -
Application of Fuzzy Logic and Neural Networks to Automatically Detect Freeway Traffic Incidents
(American Society of Civil Engineers, 1994)To date, efforts to manage freeway congestion have been seriously impeded by the inability to promptly and reliably detect the presence of traffic incidents. Traditional incident‐detection algorithms distinguish between ... -
Dynamic Pavement‐Strain Histories from Moving Traffic Load
(American Society of Civil Engineers, 1994)This paper presents the formulation and the application of a continuum‐based finite‐layer approach to evaluate dynamic pavement strains under moving traffic load. The dynamic material properties (complex shear modulus and ... -
Closure to “<i>Unified Design of Horizontal Circular Curves</i>” by Said M. Easa (January/February, 1993, Vol. 119, No. 1)
(American Society of Civil Engineers, 1994) -
Road‐Maintenance Planning Using Genetic Algorithms. I: Formulation
(American Society of Civil Engineers, 1994)The present paper demonstrates the applicability of genetic algorithms, as an optimization tool capable of overcoming combinatorial explosion, to the road‐maintenance planning problem at the network level. Genetic algorithms ... -
Road‐Maintenance Planning Using Genetic Algorithms. II: Analysis
(American Society of Civil Engineers, 1994)This paper analyzes the road‐maintenance planning problem at network level using a genetic‐algorithm program, PAVENET, which is a computer model developed to serve as an analytical tool for pavement maintenance engineers. ... -
Effect of Restriction of Vision on Driving Performance
(American Society of Civil Engineers, 1994)The effect of restricting vision on driving performance was investigated in a field study. Commonly occurring binocular visual‐field defects were simulated for a group of young normal subjects and the effect of these defects ... -
Discussion of “<i>Yearly Variation of Directional Distribution of Highway Traffic</i>” by Satish C. Sharma (May/June, 1993, Vol. 119, No. 3)
(American Society of Civil Engineers, 1994) -
Erratum:

Analysis of Accident Reduction Potentials of Pavement Markings
(American Society of Civil Engineers, 1994)The major objective of this research was to apply a probabilistic procedure to evaluate the safety effectiveness of pavement marking of undivided rural roads. A 100 sites were randomly selected from the population of ... -
Vertical Pavement Strain as Means of Weighing Vehicles
(American Society of Civil Engineers, 1994)The concept of estimating vehicle loads by weigh‐in‐motion systems that monitor deflections in strain‐gaged bridges and culverts is well established. In this project, the possibility of estimating loads by monitoring ... -
Seasonal Variation of Resilient Modulus of Subgrade Soils
(American Society of Civil Engineers, 1994)Results of a study to evaluate the seasonal variation of the resilient modulus of granular soils for flexible‐pavement design are presented. The field temperature and moisture content underneath the pavement were monitored ... -
Test and Evaluation Criteria for Side‐Impact Roadside Appurtenance Collisions
(American Society of Civil Engineers, 1994)Side‐impact collisions with roadside objects, such as trees, luminaires, signs, and guardrails, a serious type of accident, have not been adequately addressed by the roadside hardware testing community due to the difficulties ... -
Discussion of “<i>Unified Design of Horizontal Circular Curves</i>” by Said M. Easa (January/February, 1993, Vol. 119, No. 1)
(American Society of Civil Engineers, 1994) -
Effect of Material Properties on Compactability and Bearing Capacity
(American Society of Civil Engineers, 1994)The paper gives a brief literature survey on the effect of the individual properties on the compactability of untreated road‐building materials. The properties covered are the influence of the moisture content, grading ... -
Effect of Orientation of Approach Slabs on Pavement Deformation
(American Society of Civil Engineers, 1994)Differential settlements often occur between bridge abutments and the approach embankments either because the soil underlying the embankment consolidates or because the pavement and embankment materials are compressible ... -
Geometric Design of Compound Horizontal Curves
(American Society of Civil Engineers, 1994)Compound horizontal curves find applications in alignment situations involving space constraints. While typical designs for compound curves are available, specific designs can be evolved analytically to suit traffic and ... -
Basics of Flexible Pipe Structural Design
(American Society of Civil Engineers, 1994)The use of low‐stiffness flexible pipes has increased dramatically in the past few years. The flexibility of these pipes is such that the usual buried pipe models must be used with caution. Several flexible pipe models are ... -
Discussion of “<i>Statistical Evaluation of Truck Overloads</i>” by Jamshid Mohammadi and Nadir Shah (September/October, 1992, Vol. 118, No. 5)

Passenger‐Terminal Simulation Model
(American Society of Civil Engineers, 1994)A fluid approximation model for the simulation of passenger terminals is described. It is implemented via a specially designed, high‐level, passenger‐terminal simulation language, TERMSIM, which is Pascal‐based. TERMSIM ...
