Troy Atkinson, 15, killed by a car on April 28, 2009.

Stopping by Cabot Circus this evening was really sad. There's a big tower of flowers growing where Penn Street turns into Lower Castle Street, all remembering Troy Atkinson, a fifteen year old schoolboy from the city.

The flowers are from his friends, his schoolmates, his family.

In the street, traffic and people carry on. Some look at the flowers, but then they get on with their lives. The buses and cars go by as usual.

For the people standing by the memorial or chalking on the ground by it, it is not so easy. These are Troy's friends, and they are showing the world that he will be missed, that he will be remembered. And he will be, but those memories of happiness will be darkened by the pain of his loss - a pain that may fade with time, but never go away.

We in the Bristol Traffic Project -and others in the "cycling and pedestrian transport activist" community- extend our condolences and deepest sympathies to his parents, family and friends. Nobody should die in our streets, and for a fifteen year old to be lost is particularly sad.

This another dark day on Bristol's roads
