Little or no manageable or economical technology adaptable to arterial coordination has spun off from the recent federally-sponsored TOPICS programs, under which millions of dollars were spent to find solutions to traffic coordination problems in the central cities. Those systems primarily employed large data processing centrally located digital computers in which software traffic timing programs, generated from historical traffic flow data, were stored and implemented on a non-dynamic basis. There was a need, it seemed, for a better system: a system that could meet the demands of changing traffic patterns and fit the current staffing of local traffic engineering departments. The article discusses the development and application of such a system, which is based on the microprocessor. The traffic control system was developed with the following objectives: responsive to conditions as they exist in each cycle; automatically adjustable to widely varying traffic conditions; simple to set up and manage; reliable under all environmental and service conditions; adaptable to most currently installed intersection timers; universally applicable; and cost-effective solution.
