Walk back?

Neil
And the third problem is that by travelling around on buses or in our cars we aren’t getting enough exercise. And we all know that’s a bad thing! Would pedestrianisation engineer walking back into our lives do you think?

I’m not sure, Neil. It would be great if we could go shopping or walk to work without breathing in fumes or worrying about getting knocked down by a car. But banning all motorised traffic from town centres might make life difficult for people to get around.

What does the part written in bold mean?

It's not very well expressed. This is an odd use of the verb "to engineer". The "walking" is a noun.

It means "Would pedestrianisation bring walking back into our lives, do you think?", "Would pedestrianisation cause us to walk more, do you think?"

Thanks for your reply.
