I am pro-rail/transport but do massively agree that roads should be maintained to a high standard to avoid negative externalities to road users (including bus/taxi passengers!) from excessive wear. My personal resistance to
expanding road networks is because they:
- Do not actually reduce congestion*
- Are against long-term aims of reducing carbon emissions (electric cars don't solve it) - whether people like it or not that is the direction the world is going, so spending on long-term infrastructure to the contrary is not good use of public money. I might be persuaded to accept schemes which cannot easily be substituted by improved public transport for poorly served communities, though I do not think these announcements are in that category
- but most importantly, we almost never see the cost of road schemes compared to public transit projects so the arguments made against transit about ballooning costs do not get fairly applied to road projects. A holistic approach to improving connections from point A to B might suggest a road is fastest if transit would have to start from scratch. But I think if considered together with realistic modelling of capacity impacts and negative externalities to non-road users (eg home owners) I do honestly believe rail/transit would win out in the vast majority of cases.
- what about bus lanes?? Sure, widen a road but do so by adding a new bus lane (in contrast to many bus lanes which take away a lane). There would be no loss of existing road spaces for private vehicles, and those fast(er) buses should hopefully reduce the number of vehicles!
