You cannot just make it Smart iTraffic 3D without removing the major challenge from the game. Fixing some bugs and not having traffic that dumb like in the 1st game would be appreciated though.

AFAIK the way it worked in the first game, the pathfinding was a simple A* algorithm that used only the length & speed limit of each link in the network to determine the shortest path. The way this video makes it sound, travel time will be the most significant factor, which means traffic will make a difference in the pathfinding. Then they're also introducing factors related to the individual cim's need for parking, comfort, and risk-taking. It should be a lot more realistic and just as challenging, without the ridiculous situations where traffic would come to a complete standstill because everyone is taking the same route even though there are hundreds of alternative side streets to take.

As someone who's done some advanced coursework in traffic engineering, I'm pumped.
