USE VHDL using Xilinx Traffic Light Controller System for a T intersection of Main St. and 231St. managing 6 lanes. 1. INPUTS (board pins to be chosen by you): a. Car sensor for the 231t St lane facing Main St b. Pedestrian Crossing Request Signal for Main St. 2. OUTPUTs: 3 sets of traffic lights each with green, yellow, red lamps 1 digit of the seven segment displays to display counters (extra credit for 2 digits) a. b. Constants to be specified by you: MAIN GRN TIMER (MG) : Seconds that the Main St light will remain green when cars are present (waiting) on 231st St. YELLOW TIMER (Y) : Seconds that yellow lamps will stay on before transitioning to red. RED TO GREEN TIMER (R2G) : Seconds it takes a road to change to green after other road turns red (safety measure) SIDE STREET_GRN _TIMER (SSG): Seconds that 231s St will remain green. 3. 4. Specifications: Main St. (the top of the T) is a busy main road. 231st Stjs a two way, single lane side road intersecting Main St. Town Traffic Control has requested the following rules be implemented a. In the case when there are no cars waiting on 231Main St. light is to remain green. b. In the case where Main St. light is green, if there arrive cars in the sensing lane of 231 St. OR if there is a pedestrian crossing request, do the following sequence: i. After MG seconds, the Main St. green light is to change to yellow. ii. After Y seconds, the Main St. yellow light is to change to red. ili. After R2G seconds, the 231st light is to turn green and remain so for SSG seconds. iv. After SSG seconds, 231st light is to change to yellow. v. After Y seconds, the 231s yelo is to change to red vi. After R2G seconds, Main St. is to return to green and check all sensors again. USE VHDL using Xilinx Traffic Light Controller System for a T intersection of Main St. and 231St. managing 6 lanes. 1.
