Sir – To control tourist density in their centres, magnetically interesting cities like Cambridge and Oxford now clearly need to implement exceptional measures that will benefit visitors and residents alike.

This need is obvious from the informative letters in your columns, including that of Martin Murphy (August 22) who calls for a meeting of council with relevant organisations to prevent another year of uncontrolled overcrowding.

No one is to blame, and a solution will result in some losers.

Perhaps worth discussing would be radically raised summer coach parking charges (now for 52-seater £10 for 24 hours), serious penalties for on-street parking, and in addition strict regulation of the now too numerous school-age summer courses.
