I think in cities where the demand drives the transit decisions, it's pretty straightforward. Toronto has service standards. It's based on crowding. We don't have policies in Toronto that say you must have a bus come by every six or seven minutes. It's all driven by ridership. So in big cities it's pretty straightforward.
In smaller cities, it's really a policy issue. It really becomes an issue of whether you are prepared to spend money to serve a need. You have to determine what that need is and whether the money will be well spent. Is there a social need that's currently not being met in any other way? If transit is the answer to that, then you will not really be spending money very efficiently; but on a policy basis, that may be the right answer for that city.
For big cities like Toronto, it's pretty straightforward. The cities are more efficient with transit. So it's all driven by ridership. We all have our standards and policies related to that, and it's driven by the fact that more ridership that comes at you, the more buses and streetcars you have to put on the street.
