7. Simulation :
▪ By pressing simulate ,simulation will begin in
Trilogi software. And a Simulation window will appear

8. Simulation:
 By pressing start , simulation will start.
At first

9. Simulation:
▪ After sometimes

10. Simulation:
▪ Again

11. Simulation:
▪ And again after somtimes

12. Simulation :
▪ And simulation will continue if and only if we wish to stop it,if we press stop it
will stop

13. Conclusion
1.we use trilogi software for this simulation. this software is very
simple and easy to draw circuit and simulate any circuit. There are
also many software for programmable logic controllers.
2. In this project timer is very important to control the traffic signal.
3. we must be define the time value.
