And I said earlier, communication that will be mostly missed or ignored because the average passenger won't know about changes until they get impacted by them.
I'm very serious about this. My other half works in local government and every time there's some change to roads in an area they get scores of feedback saying "WHY WEREN'T WE CONSULTED?!". To which the answer is always "well there were big signs on the roadside about a consultation, we held feedback sessions and publicised them in various ways, we posted information through your letterbox..." People do not pay attention.
As I said, you could put a big banner outside someone's house saying "YOUR BUS TIMETABLE CHANGES TODAY!" and they still wouldn't notice. You can communicate all you want (and it should be done.). But that doesn't mean people will pay attention.
Remember this one true fact: the people on this forum are not your average bus users.
I do agree with a lot of that sentiment. Being balanced, if you were to adopt the approach that all comms is wasted as most people don't read anything, then nothing would ever be communicated. Clearly some people DO take notice otherwise businesses and organisations wouldn't have the expense of advertising, leaflet drops etc even if much of it does invariably go from doormat to recycling bin in about 30 seconds. I am being a bit tongue in cheek but take it further... do you advise them of the withdrawal of a service... they'll go out and when it doesn't arrive the first couple of days, then they'll get the hint? Of course not - you have to make some effort to communicate changes. Granted, you could have a plane pulling a banner or tattoo it onto their hand, and some still wouldn't notice but that doesn't mean you don't TRY (and proportionately) to advise them in advance.
Also, these are public bodies and they have an obligation, sometimes implicit and sometimes explicit, to consult and communicate. If people then don't wish to avail themselves of it, then that's fine.
I have said, many times, that people on this forum are atypical. The things that grind people's gears on here aren't the same as the real world. However, advising passengers on changes to the times of their services with hourly or half hourly headways seems sensible.
