Sir, A correspondent last week suggested that if North Oxford independent schools were to discourage students from travelling to school by car, traffic jams could be eased. This of course is true.

At Oxford High School we have just surveyed the senior department as part of Oxfordshire County Council's Better Ways to School initiative, and we see that 77 per cent of our students travel to school on foot, by cycle, or using buses.

We encourage the other 23 per cent to get out of their cars where possible, and to car share where it is not. Fewer parents using cars on the school run would be safer, and healthier, for everyone!
