BFQ-9

9. Something must be done to ease traffic congestion. In traditional small towns, people used to work and shop in the same town in which they lived; but now that stores and workplaces are located far away from residential areas, people cannot avoid traveling long distances each day.

So new businesses should be encouraged to locate closer to where their workers would live.
