TRAFFIC RESPONSIVE RAMP CONTROL THROUGH THE USE OF MICROCOMPUTER

The research was involved in the investigation, development, and implementation of ramp control hardware and software through the use of microcomputer. A prototype controller consisting of a 4-bit Intel microprocessor and 2096 x 8 bit of programmable read-only-memory was developed for exploratory study. It was concluded that the second generation N-MOS microprocessors have superior instruction power and hardware capabilities than their P-MOS predecessors. The Type 140 Controller design specification was prepared under this research. The first 200 units of the Type 140 Controller, have been purchased for implementation. Programs for traffic responsive ramp control have been developed to be implemented with the Type 140 Controller.
