Thanks for noticing the fact that "costs" accounted for in the study only includes what is (or has) actually been spent, not what what should be spent.

As Sean has pointed out, the roads are a big contributor to the infrastructure deficit because we are not spending what we should be spending just to maintain our existing road network, never mind the cost of ongoing maintenance of the thousands of km of new roads that are built to service new subdivisions.

One of the most important conclusions of the study is that it requires very high densities to make motorist charges "pay for the roads", even if one ignores the cost of negative externalities like injuries, deaths and congestion and the fact that we are not actually spending what we should be spending to maintain the road network we've got. And these high densities (and low occupancies per vehicle) mean the roads end up operating sub-optimally (i.e. we have severe congestion even on freeways, which are designed for high speeds, and many residents do not have a choice because of poor public transportation).
