The basic concept is that each time you play the game, you have up to 50 bollards that you can use to redirect and channel traffic, remove shortcuts, or prevent traffic from using bicycle paths, or really do what you want with them to try and improve the livability of the neighbourhood. Note that you are allowed to use electronic bollards.
Let's play this game twice more, having up to 50 bollards each for the University of Alberta and Twin Books.
Starting with Twin Brooks (it gets the name from the pair of creeks running, thus, twin, brooks), let's look at the neighbourhood from a map:
Bollard number 5 is just something to prevent traffic from shortcutting on neighbourhood streets, and as always, it makes cycle and walking routes shorter.
