Not many years ago the standard method of coordinating signalised intersections in local areas was to install an on-street master – each of which monitored and controlled a limited number of signal controllers or intersections as a closed-loop system. And, to a certain extent, each closed-loop system was autonomous from others deployed by the ag

    A common assumption, even amongst informed observers, is that there’s but a handful of urban charging schemes in operation around the world and scant prospect of that changing any time soon. Larger city-sized schemes such as Singapore, London and Stockholm come readily to mind but if we take a wider view and also consider urban access control and Low Emission Zones (LEZs) then the picture changes rather radically. There is a notable concentration of such schemes in Europe but worldwide the number is comfort
