    • Future Impact of Trucking Reform on Railway Revenue 

      Ahmed M. Gadi; Afifi H. Soliman (American Society of Civil Engineers, 1992)
      As vehicle weight and dimension (VWD) regulations governing the Canadian trucking industry are relaxed, the need to understand the competitive relationship between trucking and the nation's railways becomes acute. The 1990s ...

    • Statistical Evaluation of Truck Overloads 

      Jamshid Mohammadi; Nadir Shah (American Society of Civil Engineers, 1992)
      This paper examines statistics of truck overloads on highways. An overload is defined as a load that exceeds the legal truckload limit. The overload statistics depend on truck types; each is specified by the number of ...

    • Geometric Characterization of Road Humps for Speed‐Control Design 

      T. F. Fwa; L. S. Tan (American Society of Civil Engineers, 1992)
      The geometry of invidivual humps and the spacing layout of humps are two key elements in the design of speed-control road humps. This study addresses the geometric design of individual humps. The paper examines the ...

    • Change Intervals and Lost Time at Single‐Point Urban Interchanges 

      James A. Bonneson (American Society of Civil Engineers, 1992)
      The single‐point urban interchange (SPUI) is a relatively new type of diamond interchange. It is claimed to offer improved operational efficiency, improved safety, and reduced right‐of‐way requirements over other interchange ...

    • Unified Pavement Distress Index for Managing Flexible Pavements 

      C. H. Juang; S. N. Amirkhanian (American Society of Civil Engineers, 1992)
      One of the innovative approaches for maintaining and rehabilitating the nation's highways is to develop and implement some form of pavement management system (PMS). This paper documents results of a survey on PMS use in ...

    • Saturation Flow and Capacity of Shared Permissive Left‐Turn Lane 

      Feng‐Bor Lin (American Society of Civil Engineers, 1992)
      Capacity analysis is an essential task in the planning and design of signalized intersections. This task becomes difficult to perform satisfactorily when shared permissive left‐turn lanes are present. A shared permissive ...

    • Histogram‐Based Approach for Automated Pavement‐Crack Sensing 

      K. R. Kirschke; S. A. Velinsky (American Society of Civil Engineers, 1992)
      This paper presents work towards the use of histogram‐based machine vision for the automated sensing of unprepared cracks in highway pavement. Machine vision is being developed for purposes of identifying and locating ...

    • Discussion of “<i>Digital Imaging Concepts and Applications in Pavement Management</i>” by Stephen G. Ritchie (May/June, 1990, Vol. 116, No. 3) 

      J. Adolfo Acosta; Robert L. Mullen; J. Ludwig Figueroa (American Society of Civil Engineers, 1992)

    • Integrated Pavement Management System for Kennedy International Airport 

      Gonzalo R. Rada; Charles W. Schwartz; Matthew W. Witczak; Scott D. Rabinow (American Society of Civil Engineers, 1992)
      John F. Kennedy (JFK) International Airport is one of the largest and busiest airports in the world. Effective maintenance and management of JFK's extensive network of runway, taxiway, and other airfield pavements presents ...

    • Rigid‐Pavement Evaluation Using NDT—Case Study 

      Jacob Uzan (American Society of Civil Engineers, 1992)
      A case study of a highway rigid‐pavement evaluation using deflection‐based NDT is presented. The test section consists of 280 mm of concrete, 150 mm of cement‐stabilized base, and 150 mm of gravelly sand on a clayey subgrade. ...

    • Computerized Solution for Signalized Intersection Service Volumes 

      James W. Epps (American Society of Civil Engineers, 1992)
      The 1985

    • Transportation of Demineralized Water: Case Study 

      Ali A. Quraishi; Muhammad S. Al‐Amry (American Society of Civil Engineers, 1992)
      Demineralized water is corrosive to unprotected carbon steel pipelines. Lined steel pipes are generally used to reduce corrosion in the pipelines. Among the various materials used for lining, the relatively more resistant ...

    • Emerging Issues in Transportation Facilities Management 

      Sue McNeil; Michael Markow; Lance Neumann; Jeffrey Ordway; Donald Uzarski (American Society of Civil Engineers, 1992)
      During the past decade, considerable attention has been given to the country's transportation infrastructure problems. National, state, and local needs studies have documented the scope and severity of the problem. Significant ...

    • One‐Dimensional Model for Analysis of CRC Pavement Growth 

      Dapeng Xin; Dan G. Zollinger; Ray W. James (American Society of Civil Engineers, 1992)
      A one‐dimensional model for predicting the structural response of continuously reinforced concrete (CRC) pavement due to increasing temperature and alkali‐silica reaction (ASR), considering slip between concrete and ...

    • Automated Construction Field‐Data Management System 

      Bob G. McCullouch (American Society of Civil Engineers, 1992)
      Project engineers and managers involved in construction spend a disproportionate amount of time collecting and processing construction data. This processing of data typically causes the construction manager to be distracted ...
