Looking around this forum, I have found a lot of interesting city blocks. Thanks to all those who have taken the time and effort to post them.
However, a lot (most) of them use gatehouses to keep walkers "trapped". IMHO, thats a bit like cheating. I find it much more challenging to try to design blocks that work without gatehouses.
Of course, the optimal strategy is to use gates when they are available, and there is still the massive challenge of optimizing population density, cost, etc.
It would be nice, though, to see some good blocks to use where no gates are available. Such a block requires a deeper understanding of walker behaviour and creative use of this knowledge.
My own experiments have centered on 2xN rows of houses with an "industry" road on one side, connected to the entire city, and a local "service" road on the other, providing health, entertainment, education etc. for this block only.
What are your thoughts on this?
