In the long term traffic overall can creep back up to previous or even higher levels (Cairns et al 2002).

Say 2015 =100
With a 5% fall to 2017 and then +2%/year 2020 = 101
Without anything 2% growth each year would mean by 2020 = 110

Those who need to drive may move house. They could be replaced by people who can’t use alternatives, if they are suitable. Or with people who can tolerate the extra traffic/journey times.

And even the EU commission paper noted in one case study they may have just not measured the right alt routes as there could be wide detours.

I’m not aware of any study using it, only simple counts with no deduplication or trip analysis. Would love to see someone do that study.

What if ANPR confirms only a tiny percentage of traffic evaporates and that the rest is displaced from #LTNs to #RMRs ? 😬

'No to ANPR they cry. Yes to simple counts, models & guesstimates'. 🙄

Another, is why aren't councils engaging with TfL to obtain data from their #ANPR cameras already in place on the SRN at #LTN boundaries?

Why is money available for ANPR to monitor non-local-motorists entering LTNs, but none to monitor local motorists exiting them?
