These were carried out with the help of Space Syntax, the specialists in pedestrian use of public space who redesigned Trafalgar Square and the space around the Royal Festival Hall.
Space Syntax chose the key points at which to count pedestrians in Archway, and trained us in how to do the counting (10-minute stretches both during and outside rush hour on both week days, and weekends).
What we found was that at least as many if not more pedestrians than vehicles use the centre of Archway. But the vast majority of the public space in Archway is given over to vehicles, which also get the majority of time at crossings. They are also given priority in layout which forces pedestrians to use inconvenient crossings, to take the risk of dashing through the traffic.
Since the removal of the gyratory the situation has improved, though allocation of space is still not really proportional to type of use.
