    • Abstract:
      The analytical procedures presented define a method of evaluating the effects of failures in a complex dual-mode system based on a worst case steady-state analysis. The computed result is an availability figure of merit and not an absolute prediction with associated confidence levels of system availability. The advantage of this procedure is that it avoids the use of a dynamic network traffic flow simulation, which is both costly and time-consuming. The availability calculation is understandable when expressed in terms of the fraction of system time lost due to either passenger for vehicle delays. This involves both system reliability and maintainability, including the number of system failures per time interval, and corrective action times required to avoid vehicle delays.
