      Unsteady flow conditions are often encountered in hydraulic systems wherein open channel flow and submerged or pressurized flow conditions may exist simultaneously being separated by a moving interface. Examples of combined ...
    • Impact Study of Bus Lanes in Bangkok 

      Yordphol Tanaboriboon; Surasak Toonim (American Society of Civil Engineers, 1983)
      The determination of the impact on bus movements and on passenger car traffic of with‐flow bus lanes have been studied on the selected streets in the central city of Bangkok. License plate technique and classified traffic ...
    • Developing Bus Operating Cost Models: A Methodology 

      Reggie J. Caudill; Richard A. Kaplan; Anne Taylor‐Harris (American Society of Civil Engineers, 1983)
      This paper presents a methodology for developing transit bus cost models to assist in state‐level subsidy planning. Aggregate and disaggregate unit cost models for 25 bus companies operating in New Jersey are developed and ...
    • Hydraulic Resistance of Pavement Surfaces 

      Joseph R. Reed; David F. Kibler (American Society of Civil Engineers, 1983)
      The determination of Manning's
    • Erratum: “Fly Ash Sulfur Concrete” by William J. Head and Min‐Fu Liao (May, 1981) 

      Unknown author (American Society of Civil Engineers, 1983)
    • Optimization of Zonal Transit Service 

      Shou‐min Tsao; Paul Schonfeld (American Society of Civil Engineers, 1983)
      A method for optimizing the route structure and scheduling for zonal transit service is developed. It employs calculus or a quasi‐Newton algorithm to minimize a total cost function in which the zonal lengths and headways ...
    • Perceived Factors Affecting Driver Route Decisions 

      Manouchehr Vaziri; Tenny N. Lam (American Society of Civil Engineers, 1983)
      In this study, the route choice reasons of drivers making automobile work trips are analyzed in order to gain an insight into driver's route choice perceptions. Statistical analyses of 32 route choice reasons are carried ...
    • Effect of PCC Shoulders on Adjacent Concrete Lanes 

      Jihad S. Sawan (American Society of Civil Engineers, 1983)
      A structural evaluation of the Portland Cement Concrete (PCC) shoulder‐traffic lane longitudinal joint has been conducted. The influence of major design variables of PCC shoulder on the adjacent traffic lane through tying ...
