20-02-11 Model of the traffic control as promised

We discussed how the design of the traffic control (port) should be designed. We came up with this design.

The port is 100% autonomies. It has its own intelligent brick and one program running.

The design of the program is not designed yet.

The idea of the program is that the sonic sensor detects when a car come from the factory and opens.

The red stars represent a uneven surface (we have a idea that the sonic sensors, on the cars approaching the gate from the outer track, works better with a uneven surface).
