I've had a (lucky escape) collision on my bicycle on the Walkinstown roundabout about 4 years ago. I was working in Park West at the time and would cycle along Saint Peter's Road through the roundabout and along Walkinstown Avenue. At the time (I'm sure it still is) it was fairly easy to move past the congested traffic up to the roundabout; at the exit the road widen into 3 lanes; I would take and hold the centre of the middle lane and wait for a gap. Once a gap appears you need to commit and just go; I would then take up central position in the middle lane and move through the roundabout; I can't remember if I would normally give hand signals, but having to lean avoid pothole and ruts in the road, and being able to quickly brake, mean it would normally be unlikely.
On the morning in question I was at the head of the middle lane waiting for a gap. I saw a gap as a white van past which was turning off to Greenhills Road. So I went after the van and was up to speed very quickly. While looking ahead I could see the first two cars at the head of the two lanes on Lower Ballymount Road move on through the gap; I could then see the next car (red) in the outside lane start to move forward, hesitated and then went. Clearly the driver hadn't seen me (spandex clad cyclists wearing yellow top) even though I was basically in front of her, and within a second or so we had hit each other in the middle lane.
The lucky part was that she had basically pumped the accelerator and then suddenly applied the break on seeing me so her overall speed was relatively low, and in my reaction to turn away from the collision the only point of contact was a direct hit of the corner of her driver side front bumper to my rear quick release hub. This impact managed to deflect my momentum and instead of falling off the bicycle I was able to keep upright and skid out and just jump off the bicycle onto my feet. I then took a minute or so to collect myself; the driver had cleared the roundabout and ran up to make sure I was ok; she was in worst state then I was. After a couple more minutes and checking the bicycle was ok and many more reassurances to the driver I was able to continue on my journey.
A couple of weeks later I was at a cycling related meeting with the Dublin Transportation Office so I mentioned to one of the cycling consultants about my incident and my felling that the Walkinstown roundabout must be one of the most dangerous junctions in the country for all road users. The response was that there is such a large fear-factor surrounding the use of Walkinstown roundabout that drivers are much more cautious when using it. But I feel this might only apply to serious accidents which get reported to the Gardaí and a large number of small collisions like mine get unreported.
