Good to hear it!
I own the only other game for traffic management: Traffic Giant.
I played this one and couldn't believe that traffic reduction as you produced a successful system wasn't included. I finally realises that the only thing putting more buses on the road meant more traffic.
In traffic giant every person on the map was simple: they had 4 places to go to: Work, Shopping, Entertainment and School.
It was fixed at the start. Every bus/tram route you made really did make a difference regardless of how good your route planning for every line as the traffic would ACTUALLY decrease, simply and great......Your first line might only reduce it by 2%, but by your 4th line, you should have knocked out 60% of the traffic and your bus/railway/tram lines running more efficiently as a result.
When the AI did a push if it found your new line was serving one of the 4 needs, they'd try it, if found lacking the AI decided so for several reasons: (Primary) Waiting time, secondly the number of changes and finally no existent service.
I paid over £30 for this game only to realise that whilst Helsinki in Finland was now on the map in their eyes they had never ever heard of Traffic Giant from Austria.
Happily Jo Wood of Austria is gone, but before they went they produced both some crackers and corkers, along with appalling customer service, I'll reserve opinion on this company.
Traffic Giant works in Win 7, no idea what the programmers are doing now, but they got the balance obsoletely right except for the random crashes which were a major irritation.
The final unfinished game of JoWood was Railroad(Railway) Pioneer. A great game that seemed to have huge potential except for a super hole that just ate your memory until the game crashed. It had really interesting concepts within it that the first railway pioneers faced that no game has ever had, much like Traffic Giant, but on a more complex scale, simply as horse-drawn buses are simple in 1850 cities, the new idea of railways are not simple in the USA in the wilderness of the USA (of course!!) where the game is set. In Europe we faced mountains, hills, plains and forest, finally the USA got there as well. (Taking the p, in that comment but worth the interesting 4 hours of so before the game goes terminal on you.
Regardless, I loved it for the little I learnt of it before it crashed constantly (The JoWood hallmark). Rest assured, Traffic Giant is nearly bug free.
One tip: As our current computers give high scroll speeds across the map hold your right mouse button down in Traffic Giant to navigate the screen otherwise it's almost unplayable.
