Had a ride on Bristol newest roller coaster today. The positive thing is that it's open, the new infrastructure is all there and working and it's going to be free to use on Saturdays 22nd and 29th September.
However!
I used it purely as a replacement for the Long Ashton Park and Ride and, even in the middle of the day, it's a poor replacement. Despite having limited bus priority the 903 did a reasonable job of getting from Long Ashton to Bristol and back again quickly. It also encouraged group travel (the usual issue with cars) by having two children free. Metrobus takes longer and (for anybody with children) is more expensive.
The original plans for the link has been changed a few times and originally it would have used a different approach to Bristol which would have been quicker (and would have needed more guided sections). Now it runs along unprioritised roads for a lot of the time and (today) got caught up in the Temple Meads traffic both ways. Eventually this will improve (hopefully!) but not in the short term. Even without this it's slow as, instead of a direct park and ride, it's a local bus service.
The new bridge sections are great to ride across however the guided sections slow the service down (this isn't a shakedown issue where the drivers will be able to go faster as they get used to it, the guided sections are all short and few appear to offer any better acceleration opportunities than are already being used, however every one needs the additional slowing to engage/disengage with some needing it mid section as well because of footpaths!) and the majority appear unnecessary. I'd go so far as to say they'll all unnecessary if the footpath over the Ashton bridge was restricted to pedestrians (i.e. build a seperate bridge here then make the whole thing unguided).
I'd been hoping to be able to report a more positive experiance (as the m3 was and still is).
