1. Improve public transport. I wouldn't necessarily spend more money on it, but where more money is spent, I would try and ensure that as much as possible goes to improving the service to the person who ultimately pays to use the systems, the passenger (someone many governments appear to have forgotten). I would also try and ensure that all the transport in each area is integrated as much as possible (something with Transport For London, despite their faults, actually do quite well).
2. Try and improve our roads. Part of this would be to force the various companies who need to dig the road up to work together, thus minimising disruption to road users. This could be made to work, at least in Cities/large towns. We lose too much due to workmen repeatedly going and digging up the same areas of road.
   
3. Bring in tighter controls on private companies used in public service. This includes tigher controls on the contracts (which at the moment are far too open to abuse) and also limitations on outsourcing jobs handling government data (especially our personal data).
