A road intersection is comprised of a main highway and an access road. Vehicle-detection sensors are placed along lanes

and

(main road) and

and

(access road). These sensor outputs are LOW (0) when no vehicle is present and HIGH (1) when a car is present. The intersection traffic light is to be controlled according to the following logic: a. The main road light is green when vehicles are detected on both lanes of the main road and no vehicles are detected on the access road, otherwise it will be red. b. The access road light is green when vehicles are detected on both lanes of the access road and no vehicles are detected on the main road, otherwise it will be red. c. The ac cess road light is green when there is a vehicle detected on any lane of the access road and no vehicles detected on the main road, otherwise it will be red. d. The main road light is green when there is a vehicle detected on any lane of the main road and no vehicles detected on the access road, otherwise it will be red. e. The main road light is green when there are vehicles detected on all lanes, otherwise it will be red. Design a combinational circuit that will simulate the traffic light output for the main road and the access road. The main road light and the access road light is HIGH when it is green, and LOW when it is red, similar to an actual traffic light. Provide the following: a. Complete and Labelled Truth Table (10 points) b. Implementation of the Main and Access Road light output in a PROM. ( 25 points) c. Implementation of the Main and Access Road light output in a PLA.
