What is the difference between Micro and Macro?

My teacher asked me to analyse "Autonomous emergency Braking" in MATLAB simulink using Micro and Macro. What does Micro and Macro mean exactly?

This is the perfect question for your teacher. Remember that we cannot read his or her mind and that she or he is payed for giving you clear instructions.

The terms "micro" and "macro" do not appear on the linked page.
