"shared use" is my latest gripe so i had to look it up on street view. maybe it's changed since but it doesn't look clearly marked either way, be it with a "cyclists dismount" sign or something warning pedestrians like floor markings or you know... a shared use sign *eyes council*. pedestrians probably assume that they have absolute right of way, which is fair enough if there's nothing to tell them otherwise. inevitably some handle this better than others and quite a lot of people aren't going to believe you, because you're a "b***** cyclist"
by the looks of things i'd probably assume there was a dismount sign (
because... you know.... swinging your leg around the back of your bike in a busy area is the safest solution, again *eyes*).
it just looks like one of those things, where the needs of pedestrians and cyclists get so little priority, and the solution is prejudice and arguments. OR what i've noticed a lot recently, somebody seeking to improve info on cycling infrastructure has been busy on google maps, recommending routes without leaving the office to try them.
i have a lot of these problems on the a580 and i've just started using the carriage way for the duration. it's much quicker, but we cant really expect everybody to do this (though many do, including one elderly gent i saw grinding away on it just this morning)
