Mathematics and traffic an application of cellular automata

As a commuter living in a densely populated area with few public transport options I know too much about the daily traffic jams here. At work it is the #1 subject to discuss with colleagues. The Dutch speak about the traffic jams, weather and football ( but only if their team is winning ). Like eskimos have a zillion words for snow the Dutch have quite a vocabulary on traffic jams.

There is a wealth of information on the net about math applied to solving problems in traffic like this one:

Feedback MST121 TMA 01 - 1

Yesterday I received an e-mail from my math tutor with the score for a tutor marked assignment.

You got 33 out of the 40 for TMA01 part 1. Well done.
Some remarks,

Try to give your answers as a conclusion.
Q1 (c) Look for an easy factorisation.
Make sure that the answers satisfy that x is not 0 and 2x-1 is not 0 so that both are solutions.

The course supports the use of the floating "symbolic toolbar"
The solution sould look like:
42 x^3 + 301x^2 + 154 x -840 factor ___ (7(2x+5)(3x-4)(x+6)

Make sure that you get used to the decimal point and notthe comma.

Always give the range,.
Check the difference between decimal points and significant figures,

Mathematics: is it the fabric of MEST?
This is my voyage
My continuous mission
To uncover hidden structures
To create new theorems and proofs
To boldly go where no man has gone before

(Raumpatrouille – Die phantastischen Abenteuer des Raumschiffes Orion, colloquially aka Raumpatrouille Orion was the first German science fiction television series. Its seven episodes were broadcast by ARD beginning September 17, 1966. The series has since acquired cult status in Germany. Broadcast six years before Star Trek first aired in West Germany (in 1972), it became a huge success.)
