SYNCHRONOUS LONGITUDINAL GUIDANCE (SLG) ALLOCATION ALGORITHM EFFECTIVENESS STUDY

A previously developed algorithm for allocating guideway space in a deterministic automated transportation network has already been verified as being a useful traffic management technique. This report investigates the algorithm's effectiveness under a variety of network operating policies and demand conditions. The report develops a methodology for the evaluation of algorithm effectiveness, evaluates the algorithm's effectiveness in representative transportation network traffic conditions which may degrade effectiveness. Algorithm operation, as determined by computer simulation, is defined to be effective if it produces traffic patterns which match those obtained using linear programming optimization techniques. It was concluded that the algorithm is a useful, flexible and effective tool in controlling traffic patterns in a deterministic transportation system. (Author)
