One example that comes to mind would be four neighbourhoods in a row along a freeway. At each neighbourhood, traffic slows to 30mph to handle local traffic. Does it make sense to build a bypass to facilitate getting directly from neighbourhood A to D? Observing axle counts only tells you the volume from A to B, B to C, and C to D, but doesn't provide information about new roads or routes that might improve things.
