Oxfords P&R though is a local bus service, not a P&R bus. It may be advertised as such but it's not really.
This is the issue with many P&R schemes, they are meant to be there to get people out of their cars but then set silly fares which make it unattractive to the supposed target audience. Pay for parking and pay for the bus. Then they add so many potential saver style tickets that the bus tickets become more complicated than that of the core commercial bus network. It's daft.
What I don't get is why do we charge for P&R buses 'per passenger' yet if someone was to drive into the town centre and pay for parking, they would pay 'per car'. This is one of the biggest reasons cited by people about using the bus, it's cheaper to drive if there is more than one of you, yet P&R puts itself into that category. It makes no sense.
Take Reading as an example, It's £7 for a group (after 9.30 M-F & All day Sat&Sun) but if you're not planning to spend long in town, it's £8 to park at the Oracle for 4 hours. Centrally located, less faff. Off 2 people, that's 50p per person to save on the 'hassle' of using P&R.
Chester, £2 per person (normally). If alone, great, it's cheaper. If you're with others, £4 gets you 4 hours in the city, £5 gets you £6 hours. Why would you get the P&R bus when you can go into town instead?
P&R sites should be future ready and most of them aren't. Most have extremely basic cycle facilities (what about those who like to ride their bike but dislike it in slightly congested city streets, P&R should be suitable for that), many have no electric car charging points. City Centre stops may be poor, congestion with councils having no will in the world to put in bus priority. There are so many reasons why people won't use P&R, unfortunately, those in power are completely blind to how to increase P&R usage and very much like the attitudes when it comes to public transport in general, they ignore the issues or pass the blame onto someone else.
