My experience of these types of crossings when on holiday is predominantly negative.
It’s a constant “Can I? Can’t I’ cross? Is he going to stop?
And then after a few days when you get confident with it you’ll inevitably have a near miss and revert back to edging out.
I’m not sure the UK’s adherence to current zebra crossings is great?
It would also be interesting to see the impact on air quality?
Walking might go up (and therefore car usage go down). But the stop start of traffic, with no central control or ‘traffic managing system’ is surely is going to cause issues?
Furthermore, the roll out and cost to implement and maintain would still be huge, even without the infrastructure costs of belisha beacons.
Cant help but think that money could be better spent on other ideas, not least creating walking routes with minimal / zero crossing of roads and conflict with vehicles?
