The commitment is to develop a national strategy for 20mph zones and limits in Scotland which:
...will identify a number of outcomes to assist in the further delivery of 20mph zones and limits on those roads where it is appropriate to do so.
Then to undertake a review of national guidance, then to develop an implementation plan for the strategy.
Nice work for Jacobs and Aecom who drafted this, not so good for the people who will die waiting for change.
Remember, at the end of this 20mph limits will still have to go through the speed limit order process (same as the TRO process) and be reliant on forward thinking councillors and officers willing to take the stick from nimbys and political opponents.
