Council chiefs are conducting a survey following a surge in complaints against cyclists at a busy Dublin city bridge.
The local authority has installed cameras at Baggot Street Bridge to snap bike users who are breaking red lights.
Pedestrians had complained that walking the route along the canal and then across the bridge had become more dangerous since the council opened a cycle track in March this year.
There have also been complaints that the lights for cyclists are too small.
As a result, the council commissioned a survey of pedestrians.
A mobile camera was set up to watch cyclists as they approach the junction and go over the bridge.
They were photographed yesterday between 7am and 11am and again from 6.45pm onwards.
In addition, pedestrians are being asked if their walk has become more dangerous, less dangerous, or is the same, since the cycle route was installed.
There have been a lot of accidents here," said one of the researchers on the bridge. "I saw an accident the other day between a cyclist and a bus. The cyclist came out of nowhere."
It comes only days after news that Dublin cyclists, as well as pedestrians and bikers, are to be targeted by gardai.
Officers are watching out for cyclists who go through red lights, cycle on footpaths or travel the wrong way on a one-way street.The campaign will see awareness of road safety raised though electronic messaging at Luas stops and roadside messages.
Buses and bus shelters will carry road safety posters.
Running for eight weeks, the campaign is aimed at reducing accidents involving vulnerable road users.
In February, Labour TD Kevin Humphreys said cyclists should be handed on-the-spot fines for breaking the rules of the road.
He said the behaviour of a "significant minority" was giving them a bad name.
The Dublin South TD was responding to a survey of around 200 cyclists from tyre manufacturer Semperit Ireland.
It had found that 21pc were using footpaths, 19pc broke red lights and 14pc went against the flow of traffic.
"The use of footpaths by cyclists is particularly dangerous to the elderly," Mr Humphreys said.
