Abstract:This report is concerned with the evaluation of alternative freeway merging control systems from a cost-effectiveness standpoint. Alternative systems that were evaluated include: 1) Analog Satellite System, 2) Digital Satellite System, and 3) Digital Central Control System. The report also provides a methodology for evaluating the cost-effectiveness of freeway control systems. This methodology is consistent with a multilevel system design concept. The multilevel approach is directed towards establishing a hierarchy of control that results not only in an efficient system but one that can be implemented in stages. Each succeeding stage results in increased system sophistication and consequently an increase in cost. The cost-effectiveness of each of four stages (or levels) of control has been evaluated and is reported herein.
