I read your report of the woman cyclist seriously injured last Thursday near the Cherwell Drive junction at Marston, Oxford (Oxford Mail, July 11).

In January 2005, I organised a petition to try to get traffic lights, instead of the mini-roundabout, at the junction of Cherwell Drive and Marsh Lane, near the doctor's surgery where two accidents had occurred, one serious.

After collecting almost 600 signatures, three years have passed, and the mini-roundabouts are still there.

The traffic is now a lot worse, with the new children's hospital and West Wing at the John Radcliffe off Headley Way finished and still more new buildings being developed.

When will the authorities take notice and have a different system installed - traffic lights?

It would help to have a cycle path or cycle lanes in Cherwell Drive and Marsh Lane - part of the grass verges could be used.

I lived in Marston from 1939 until I moved to Thame two-and-a-half years ago, after getting a no-right-turn exit from the service road by the shops and doctor's, which I believe has been a success.
