How many Beatles fans end up at the wrong Abbey Road?

Beatles fans looking for a famous zebra crossing need to go to Abbey Road in St John’s Wood near Regents Park, but many accidentally end up at Abbey Road DLR station in east London by mistake.
So many do so that there’s even a cleverly written sign telling people how to get to the correct Abbey Road. Originally a simple poster, it’s now a proper permanent enamel sign.
