Previously I said that Park n' Rides, or car parks at stations were a bad idea, but the reality is we need them now and in the near future. People use them. My family uses them. Most of them are at freeway stations that are hard to walk to and offer little redevelopment opportunity anyway. But they can be improved.
For one, the concept of partly free parking and partly paid parking is a good one. However the paid bays are at the back, so those who paid are further inconvenienced by walking further, while those who got free parking also get parking close to the station, so the only way to get convenient parking is, well, to arrive early. Or at least this is the set up at Stirling train station; I haven't seen the other stations but I suspect the situation is the same. It would be better to have paid parking at the front and free parking at the back, so people can pay for the convenience of parking near the station.
