I'm not sure what you mean by adjustments to infrastructure, but when you look at the challenge of transportation with respect to public transit, as discussed earlier, we're looking at a range of measures. We're including things that increase ridership. We're including things that expand the capacity of a public transit system to absorb more riders. We talk about changes to the urban forum.
I don't think we can talk about public transit or measures to increase ridership without talking about the urban forum. We would suggest that we need to look at ways of encouraging more compact forms of urban design.
