This sounds like a ridiculously simple idea, but how about
The club sell all season tickets at 'face value' eg no subsidy
If you don't want to use public transport, you don't pay the transport costs added on
If you use the train within certain boundary zones (could be set like London with zones 1-6), you pay for a 'football train season ticket' on top
If you want to use a bus within certain boundary zones you pay for a 'football bus season ticket on top'
Season tickets for transport issued seperately and only available for use on match days before and after game within specific zones
Club only pays a transport subsidy for those that use it
Use of 'zoned season tickets' means club and bus company know exactly how many buses/coaches they will need to maximise efficiency in each zone. Could even look at STH's specifying a pick-up location to make things even easier for routing/
General Sale ticket holders just pay for their travel as they would on any other day for any other purpose (or can pre-book at the time of booking their ticket if they want to use a 'special bus service e.g. Rottingdean'.)
It's not really rocket science, makes things cheaper for those who walk / drive, saves money for the club by no longer subisiding travel for those who don't use it.
The first season at The Amex proved that a voluntary opt in scheme doesn't work. 90% or more travelled for free once word got around there were no ticket checks on the trains to collect the travel vouchers and likewise on the buses fans just waved the season ticket card or paper ticket at the driver. Creating exemptions causes more problems than it solves.
