ring-road

It is 39 metres across the Barton Park junction cycling from Barton Park to Northway, and 46 metres going the other way, measuring the distance from the stop line to the edge of the far-side A40 traffic lane. Analysis of the signal timings reveals that the time allocated for crossing this - the "intergreen" between the green light for buses and cycles ending and the green light for motor traffic on the A40 starting - is the same in both directions, just 8 seconds.

The speed limit on Oxford's ring-road should be reduced to 30mph where there are significant at-grade crossings (such as at Barton Park, Kiln Lane) and reduced to 40mph where it passes housing (past Rose Hill, Littlemore, Wood Farm, etc.). This would help with road danger, community severance and barriers to walking and cycling, and with noise pollution, but also with air pollution, vehicle collisions, and carbon emissions. more
