Dublin Cycling Campaign says its survey highlights the need for urgent work on the Liffey Cycle Route.

The project, which would provide a segregated track linking Phoenix Park to the Point Village, has been in planning stages for seven years.
The group will hold a mass protest along the quays this Sunday and says it this will continue every month until there is progress.
"We know from statistics that approximately three people per day are taken to hospital in Ireland as a result of collisions while cycling," said Kieran Ryan of Dublin Cycling Campaign.
