How would that work, junegapi? Do you mean alternating contraflows up and down the road, with pinch points where people have to wait and give way? I've found those make people even more aggressive. More than once I've seen two cars wedged in a pinch point because the person who should have waited just refused to.

The main problem with Devonshire Road is that it is just too narrow when fully parked to implement almost any of the traffic calming methods suggested. Short of stopping all parking, which would be impossible for residents, what can be done?
