^ Your increasing population is dealing with finite road space though. Bulldozing buildings downtown to make wider roads is not an option.
If the roads are already full, the only way to handle increasing use is to get more people on the existing infrastructure, or building new infrastructure below grade. Things like:
1) 4 car trains
2) subway
3) Increased bus service
4) car pool/transit lanes
5) bike lanes
Guess which are the cheapest? 4 & 5.
