the main obstacles to better bus services, ones that keep to time, don't cost too much and go where people want to go and in a reasonable time to get there, is traffic congestion and the allocation of road space.
Almost everyone knows this already. Cambridge starts from a position where the amount of road space available is tiny, with all of the main routes single carriageway, except for a few short sections of Newmarket Road and Madingley Road. It is further constrained by having very few bridges over the river and the railway. That isn't going to change. Almost everyone also knows that one of the three biggest contributors to congestion is road works because single carriageway roads mean that road works almost always mean temporary traffic lights.
Severe restrictions on where you can drive, and severe financial penalties on not just where you can park, but the provision of parking itself.
This won't happen in Cambridge because the car parking charges are an important source of income, and cars need to get in and out of the car parks.
You have hit the nail on the head by mentioning Cambridges chronic congestion, a fact that nobody has the courage to follow through to resolve. Congestion Charge, Working Place Parking Levy, pollution traffic control measures all have been proposed consulted upon and rejected by hm guess who?
The so called sustainable travel zone fell on the stony ground of the cost of living crisis. All solutions that hit the pockets of "hard working families" are off the agenda for the foreseeable future.
given Cambridge's history, the only reason they want franchising is so they can force buses to use expensively procured infrastructure like a busway, bus lanes or park and rides.
This should be the main reason for bus reform. It is absolutely right that expensive infrastructure should be used. Whatever the guided busway history, it is here now and needs to be used much better. The bus companies have a very poor record on this, especially buses stuck in traffic in Hills Road instead of using the busway. There are also controversial proposals for new (though not guided) busways.
So that only leaves benefits like cheaper integrated ticketing with rail,
Once Cambridge South opens next year, integrated ticketing is going to be critical. For the first time in history it is going to be possible to make a daytime journey from one side of Cambridge to the other in 10-15 minutes, just by getting on a train. A key way of reducing congestion is to get through journeys off of congested streets within the city, and onto the train. For example, St Ives-Biomedical Campus journeys need to be combined bus and train via Cambridge North, not stuck in traffic on Milton Road or Histon Road.
Integrated ticketing is not a direct benefit of bus reform, but it is an opportunity created by what's in the pipeline for devolution and Great British Railways.
As always, the benefits of such things stand or fall on the competency and capability of local politicians and civil servants.
In the case of bus franchising in Cambridgeshire, this is a significant risk, and the main reason why I preferred the enhanced partnership. That's not going to go down well in a consultation response so I didn't bother to tell them that!
