Sir – Traffic congestion is even more on our minds in Oxford city than usual and I’ve been reading suggested ways of alleviating this daily stress bordering on the extreme — bus tunnels under High Street and elevated walk-ways on Queen Street — when the most practical solution is to make public transport more convenient for everybody.

To do this, buses must have priority in the city. If they were cash-free at the point of use, and used dedicated lanes into and then out of the city — say switching at noon each day — our buses could keep to schedule.

Some people would gladly leave their cars, and others who really need to drive would face fewer snarl-ups. Everyone would benefit from less air and noise pollution — and less stress. Ultimately, we could perhaps have many more, but smaller, more ergonomic buses that could travel through our ancient central streets without disturbing pedestrians and cyclists unduly.
