You've also got the Townsend/Breck road route in too Tom.Yes, a certain number will not have access to a direct public transport service, be that via Merseyrail or buses to the city centre (or a combination of both with onward shuttle or walk), and a proportion of those will have mobility issues. However, the consultation process was supposed to be about establishing those numbers, and with well over 20k of our season tkt holders having a Liverpool/Merseyside postcode, the idea was to try to capture the vast majority of those local based supporters with the modal shift to public transport, as projected in the transport plan. Thus freeing up roads for those who really need them.... and keeping the immediate road space clear for public transport access/egress and disability access and drop-offs.
As Furey1878 has shown above, all of the eastern arterial routes, (ie the bulk of the Liverpool conurbation), do not have direct public transport routes to BMD. Merseyrail essentially skirts around the majority of the city's suburbs and existing bus routes serving all of them do not go within a mile of the stadium.
Of the routes shown, the Walton Lane/East Lancs Rd route is only covered by the 19 bus route, which doesn't come down to Scotland Rd, as it cuts back inland to go up St Domingo Rd. So its nearest point is probably the top of Everton Valley. Those fans would probably be less inclined to leave their cars at home because the available service is too distant, and to go into town is probably too convoluted and inconvenient.... so a shuttle service to the Goodison area could have helped (and allowed many fans to use familiar parking spaces away from BMD too). All of the other north eastern bus services enter the city centre via London Rd. If just a small proportion of these buses could be diverted or extended on matchdays to offer more direct routes to the area, this could take a lot of pressure off the shuttles, and add significantly more "direct services" and keep more people out of their cars. Similar for bus routes serving the south eastern corridors. Just say 1 in 4 (or 5) of every bus route extended to BMD would greatly improve bus capacity and comvenience.
We have also already seen that Sandhills Stn itself is limited in its present format.... so the onus is being placed on Shuttle buses to make that connection with the city centre and all of major local and regional public transport capacity. That system also has limited capacity at present. So the shortfall at present is essentially filled by the "walking" option.
When we go to the area which is often we never use the same route twice

All congested ratruns even on a quiet none matchday Sunday.
My view is it's fine to walk half an hour to Goodison, parking up outside current zones.
Whether that be bottom of Cherry Lane/Towsend ave or back towards Norris Green.....Kirkdale for some.
The half hour walk is not the issue, it's the half hour walk then the slog onwards on Public Transport....if any goes your way.
Serious amounts of shuttles needed for all fans whether they be in cars or on Public Transport.
