ANALYSIS OF DOWNTOWN PEOPLE MOVER SYSTEMS BY USING THE DPM SIMULATION MODEL

Downtown people movers (DPMs), a class of automated transit system that operates on exclusive guideways, are being considered by many cities as a possible solution to their circulation and distribution problems. This paper describes how a discrete event- simulation model developed by the Transportation Systems Center can be used in the planning and design of DPM systems. The paper identifies the variables that can be studied and that affect system ridership, cost, and performance by the model. The key inputs, the modeling functions, and outputs of the model are discussed in the context of an example, the 1990 Los Angeles DPM system. Use of the model to determine the feasible combinations of fleet size, vehicle capacity, and operating headway to meet the Los Angeles DPM system performance goals for the year 2000 is discussed. Finally, the use of the model to examine the effects of a vehicle failure on passenger service and system operation and to evaluate three algorithms for system recovery is illustrated. (Author)
