Which Asset should I buy for my traffic problem?

HI
I develope a game, but i can’t write code . I only design my own graphics. I have a friend who writes c# but he doesn’t have time and experience to program all of my game, so I rely mostly on solutions from the Asset Store. Most of my game will be made with the (most awesome) adventure creator plus the great fps maker, so a lot of what is needed is covered.

What I need as well is a working traffic system for cars, and (if possible) for pedestriants. My game isn’t made for a hard core audience, so I can’t just shovel something down their throats. It needs to be sufficiant, but at the same time it shouldn’t ask for too much computational runtime. I guess that my audience have PCs from the last 5 years. Also, I only have a small number of streets, so the scene is not too complicated after all. What i have is 4 different Time environments of the same place which use totally different cars . But I guess that is not much of a problem when using scenes.

I have already bought a traffic system and a racing system which I thought could offer a kind of workaround, but they don’t. Actually one of them sux bad and I don’rt want to spend money on the wrong item again, which is why I ask you guys what you might recommend.

The following simple illustrations should easily indicate the most important facts

please note

  1. in order to make this work, i must be able to use my own streets - this is a capture of a real world scenery and it took a lot of time to match it.

  2. I don’t need hundrets of cars on the road. A controlled number of 15 to 20 random or predetermined cars should be enough. Later in the developement of the game, there will be a bus that will come regularily and wich has to stay on one predetermined course…

  3. I bought some very nice animated traffic lights which look exactly the way they need to be. They are only missing lights for the walkways… well… thats another problem.

If possible, it would be great to have these Traffic lights visible in my game and synced to the traffic system of the AI. If that doesn’t work at all… oh well, then I can’t help it either, but most traffic lights I saw in prevews for AI Assets looked terrible and in no way like in this real world place.

  1. I don’t have unity pro yet. Actually only a matter of time until I have to get it, but not for the foreseeable future since thats a lot of money spent at once. .

Road & Traffic System has been very popular on the asset store of late. I haven’t used it though.

Thanks for the advice. Making own tracks (on own meshes) Seems a bit tidious according to the tutorials, but I guess it serves my purpose.
