Measures such as this are a real pain for everyone...
As a cyclist, I've seen this stuff implemented in Oxford, UK and here in the USA. Regarding "Chokers" there is nothing worse than an unpredictable roadway edge that squeezes bikes and car together. I've even seen designs that force opposite directions to meet head-on.
As for speed humps... I see good, bad and ugly. Some are unrideable on a bike - I once crashed as a result of a bump, cycling well below the speed limit... and they punish the users of small cars more than those in large, less efficient vehicles. If the speed limit on a road is, say 30mph then why put speed humps that invariably slow traffic beneath that limit at intervals? Change the limit and do something sensible about enforcement if cars are travelling too fast.
OK, that's my 2p
