I agree with the principle, but:
1) Colchester seems to forget that it has a large rural hinterland. Unless public transport is improved for those visiting their city, the plan is at odds with reality. Tiptree with a large population of over 10,000 does not have an adequate bus service to Colchester. Instead of large lumbering buses being used out of peak hours, a fleet of smaller vehicles that run more frequently is required. A town bus service of every 10 minutes is good. Outside the town every 20 minutes would be acceptable, but the best we have ever had is 30 minutes and it is now reduced to 60 minutes outside peak times. This is inconvenient for appointment times (you even need an appointment to do simple banking transactions). With an infrequent bus service this leads to killing time. What if it is raining? Can you afford to go to a cafe to kill time? Rural residents contribute to the facilities in Colchester, but an infrequent bus service in incompatible with busy lives. Tiptree has no bus service after early evening, so a trip to say the theatre is not possible without a car, and night taxi rates are not affordable for frequent trips.
2) The rural transport situation is always "going to be considered", but there is never much progress.
3) Commercial transport will never act for the good of the community, the benefits of better public transport are not counted in commercial terms, but we need it in social and environmental terms.
4) Very little is said about the disabled.
5) The elderly who do not qualify as disabled, also find walking a distance and scrambling on and off various vehicles and having to stand as there is insufficient seating and lack of consideration.
6) The Park & Ride in the north means travelling on the A12 to access it from the south / west. Not everyone likes driving on the A12. I can still cope with it, but many can't with the mix of fast traffic and congestion.
