You talk too much. You should ask questions one by one. How can you finish all these questions at once? It is dead.

I write a question of 14, safety interval s, speed v and time t.

(This test can be taken at will. Anyway, the traffic in one minute is the largest, and the traffic in one hour is the largest, and so is the traffic in one second.

Then S=K0 times v 2,

The traffic volume at time t is Q=VT/(L+S)=T/(L/v+K0*V)? The change in this step is that the denominator of the numerator is divided by v.

You should see it next. This is a tick function. This kind of play is really tiring. Let me take a screenshot.

Please contact me if you need other answers. Typing is too tired.
