    • Correction of Head Loss Measurements in Water Mains 

      Thomas M. Walski (American Society of Civil Engineers, 1985)
      Pipe roughness or carrying capacity are occasionally determined in water mains to assess the internal condition of the mains or determine coefficients for pipe network models. As part of these tests, it it necessary to ...
    • Railway Route Rationalization: a Valuation Model 

      David Arditi; Dan Steven Krieter (American Society of Civil Engineers, 1985)
      Abandonment of rail branches and secondary lines with low traffic density is an effective means of maintaining railway company profitability in many countries such as Britain, Canada, Australia, and Japan. In the United ...
    • Statistical Designation of Traffic Control Subareas 

      James E. Moore; Paul P. Jovanis (American Society of Civil Engineers, 1985)
      A method for identifying control subareas in traffic signal networks has been developed and tested with data from the Miami, Florida, business district. The procedure combines the use of cluster and discriminant analysis ...
    • Examining Air Travel Demand Using Time Series Data 

      Ashish Sen (American Society of Civil Engineers, 1985)
      One of the most commonly available types of data available to transportation public and private properties are monthly data on ridership and revenue. A technique, based almost solely on such data, for determining the of ...
    • Pedestrian Traffic on Cincinnati Skywalk System 

      Manmohan K. Bhalla; Prahlad D. Pant (American Society of Civil Engineers, 1985)
      A method for estimating pedestrian trips on the sky walk system in the central business district of Cincinnati, Ohio has been developed. The central business district experiences congestion and conflicting pedestrin‐vehicle ...
    • 3R Standards Implementation 

      David K. Phillips (American Society of Civil Engineers, 1985)
      The Surface Transportation Assistance Act of 1982 increased the Federal funding for highway improvements by well over 50%. In that act, Congress also directed that a large portion of the non‐Interstate funds be used for ...
    • Minimum‐Cost Design of Flexible Pavements 

      Nagui M. Rouphail (American Society of Civil Engineers, 1985)
      The formulation of a mixed integer‐linear programming model to determine a minimum‐cost flexible pavement design is presented. The model identifies the number, type, and thicknesses of paving materials required to meet the ...
    • Design, Construction and Maintenance of Torrijos Airport 

      Maurice S. Greenberg; Vernon A. Smoots; Rudy M. Pacal (American Society of Civil Engineers, 1985)
      In 1970, the Direccion de Aercmautica Civil (DAC) of the Republic of Panama realized that its facilities at Tocumen International Airport could not accommodate the heavy jumbo jet traffic of world airlines using the airport ...
    • High‐Speed Rail Systems in the United States 

      Unknown author (American Society of Civil Engineers, 1985)
      A great resurgence of interest in High Speed Rail (HSR) Systems is occurring in the U.S. Several intercity corridors are under detailed scrutiny for application of various HSR technologies that have been developed or are ...
    • Selected Bibliography on Traffic Operations 

      Unknown author (American Society of Civil Engineers, 1985)
      A select list of references pertaining to traffic operations is presented. The list contains 62 references including handbooks, manuals, conference proceedings, textbooks, and case studies that the committee considers ...
    • Are Pedestrians Safe at Right‐Turn‐On‐Red Intersections? 

      Himmat S. Chadda; Paul M. Schonfeld (American Society of Civil Engineers, 1985)
      The permission of right‐turn‐on‐red (RTOR) at signalized intersections has operational, fuel consumption and air quality benefits but poses safety hazards, especially for pedestrians. A review and analysis of this pedestrian ...
    • Scheduling of Demand‐Responsive Transit Vehicles 

      Shinya Kikuchi (American Society of Civil Engineers, 1984)
      This paper presents a vehicle dispatching procedure designed to minimize empty vehicle travel and idle time for a demand‐responsive transportation system. The method schedules the empty vehicle assignment between passenger ...
    • Blowup of Concrete Pavements 

      Arnold D. Kerr; W. Alex Dallis, Jr. (American Society of Civil Engineers, 1985)
      Blowups of concrete pavements are caused by axial compression forces induced in the pavements by a rise in temperature and moisture. Although numerous papers and reports have been published on this subject, they have not ...
    • Elasto‐Dynamic Analysis of Pavement Deflections 

      Michael S. Mamlouk; Trevor G. Davies (American Society of Civil Engineers, 1984)
      An elastodynamic analysis of pavement response to harmonic‐load nondestructive testing is presented. The method is based on a discrete layer approach that assumes linear variation of displacements in the direction of ...
