Transportation model: defining the generator
Well done; you have defined your model inputs and outputs and the model processes you characterized using Python methods. Now, it's time to put a generator together that will sequence all your model processes.

Instructions
- Call the function
road_travel()created before, which calculates the road travel time, and clock in the time it takes to complete it. - Call the function
wait_traffic_light()created before, which calculates the waiting time at traffic lights, and clock in the time it takes to complete it.
