For this type of traffic light controller, a FAB intelligent micro controller unit is us ed to program the desired traffic light sequence that includes the ambulance safe pass sequence.The building blocks inside Johnson tenner counters, astable multi-vibrator timers and the FAB micro controller such as logic circuits, flip flops, Karnaugh maps, truth tables and Boolean expressions are also presented in the Appendix section of the report.Traffic lights are an essential part of modern life, especially with the increasing number of vehicles that coincides with the increasing number of population. Traffic lights not only regulate traffic lean in the streets but more importantly prevent the occurrence of vehicular accidents. Roads without traffic lights are unimaginable. The traffic light controller is a nonparallel device that needs to be designed and programmed by dint of multiple step procedures. A proper traffic light requires accurate timing, correct cycling through the states, and responds to outside outputs such as walk signals or ambulance safe passage.The object ive of this report is to design and implement traffic light controllers for a simple North/ South and East/ West road crossing as shown in figure below.
