Well, I was being a little flippant, but thank-you for the comments about the quality of the paper! As I’m sure you can imagine the council isn’t often complimented on them.
But there is a wider point in how councils consult and communicate. As you point out there was significant variation between the roads’ responses, but this isn’t the sort of thing that can be introduced in isolation. The effects will be felt in roads some distance away as drivers adapt and change their habits. In six months’ time asking the same question in the same roads may elicit a totally different response as they have seen the effects of the changes.
The art in this (and I think it is an art, rather than a science) is often as much about how you interpret the answers. You rightly point out that the roads that didn’t respond were mews houses that do not have through traffic and, therefore, don’t have the incentive for change. However, they may have (but not realise they it yet) an incentive to keep the status quo because they use certain routes. As someone cynically commented to me recently, people are very keen in traffic calming on residential roads – just not the residential roads they drive to work on. Working out what to do from a relatively small and not so clear cut response isn’t just about what people say now, but also trying to anticipate the complaints and campaigns that will arise in six months.
