Here's the set up: http://home.comcast.net/~maginnis/zones3.JPG The highway leading to the northwest takes commuters to another city, a small map filled with industrial zones. The connection works perfectly fine: the industry in the small map has developed and the residential zones in the big map support 15,000 residents. Here's the problem: http://home.comcast.net/~maginnis/traffic3.JPG The commuters aren't using the highway like they should be. They ignore the highway on-ramps located near their homes and decide to only use the avenues until they run out of avenue. The avenues that feed into the two red-dot on-ramps are completed congested, while the blue-dot on-ramps are completely ignored. Residential zones are being abandoned due to commute time because of the red-dot bottleneck. I've tested this by laying out industrial zones inside the residential-only map, to the south-west of the portion in the pictures. Those industry zones get developed and do support nearby residential zones. I'm using the latest NAM with the improved pathfinding option, but nothing else. So, what's up? I don't mind if I have to scrap the whole city, but I'd like to know why those commuters refuse to use the other on-ramps. Really sorry if there's something completely obvious that I'm missing, I'm still pretty new to the game.
