i need a traffic simulation matlab code. it should include numerical methods and differential equations, as well as a validation mechanism. it can be about traffic lights and make the simulation of how yellow light would make the cars in the lane decelerate, red would make them stop and green would make them move. make sure to write the code from scratch, and use differential equations. make a graphic simulation, not just a graphical plot. The cars should be moving and responding to traffic lights. make sure the code isnt buggy URGENT
