This is a long-term project to track bicycle collisions in the city.

The Road Safety Authority maps some data for cycle collisions. But what about the smaller collisions that cyclists face day to day, which might put them off cycling, or hint that certain intersections might be unsafe for cyclists?

Do these smaller crashes happen in the same places over and over again? Do some intersections that need to be redesigned to keep cyclists safe? We’d like your help to try to work this out.

If you’ve been involved in a bicycle collision in the city, let us know the details by marking it on the map below, and filling in our form.

Zoom in if you need to, click on the spot where the accident happened, and then click “Next” in the top right corner of the map and answer a few questions.


Here are all the collisions reported so far.

We couldn’t have got this up and running without the help of data wizard Mick O’Brien, who volunteered his skills.

  1. Great initiative!

    Have a look at Save a Selfie (; the underlying code is probably very similar, in terms of needs – for website and apps. (In the bike-accident version, a person would take a snap of an accident location using the app, give a description, maybe select an accident type, and hit the upload button; GPS info uploads at same time, and the info goes straight to the website and map on the app.)

  2. Great idea. Would it be a huge effort to have a second version for people to record near misses. These could put a person off for cycling for life without a collision. I have had two at the same junction where the an M3 slip lane meets a roundabout. People fail to yield to cycles and on one occasion I actually touched the offending car. I have been cycling for over forty years and this nearly put me off for life. If other people logged the same then a solution could be found as we have the data to show the issue. Just because I was paying attention and braked hard, avoiding being killed does not mean there is no problem. Well done on a good initiative.

    1. Agreed, a near miss map would be great. As an experienced cyclist I’ve had many many near misses with cars whose occupants had no idea of the danger they put me in.

  3. We have a database of over 4000 dangerous intersections already that is supported by accident records and news articles. Do you want to use our map? See

  4. ban 4X4s bring in congestion charge. raise V R T on large German cars. use guards on bikes To nick threatening drivers

  5. Really nice Idea. Haven’t had a collision yet but as others here, I’ve had near misses. Also it would be nice to alert people of poor stretches of road for cyclist. I know many where I’ve been squeezed out of the road by drivers using imaginary two lanes.
    Also, for balance, drivers and pedestrians being able to report spots known for poor cycling practice would be useful and show that it’s not just an attack on drivers.

  6. A great idea by you need to colour code your hit-points before you get too much indistinguishable data – currently it looks like there’s been loads of collisions but if you click into them, half of them are “near miss” and one is from 2006! Hardly representative of present danger.

    Perhaps yellow for near miss, and 3 shades of both yellow and red for recency? e.g. within the last year, last 3 years, > 3 years?

  7. Can you use this to report incidents that you were not personally involved in ? Otherwise how is it possible to add fatal incidents ?

  8. Not only the ability to add fatalities, but also as someone whose was severely injured and logged it, I’m still awaiting contact for verification, without verifying the data, DubInq data will not be credible.

    1. Hi Ali, yes, that’s a fair point. We’re just a bit short of resources at this end so have contacted people to verify when we’ve done the pull-out stories from the data but not everybody. (When you click on the dots on the map, it does say “unverified”. I actually need to update the ones we have verified, though.) I did apply for a grant that would have let us pay somebody to do more with the data, and verify it etc but we didn’t get it. So, we’ll just have to do it bit by bit I think for now, given that we have limited resources.

  9. Add features for other road users to report incidents of cyclist near misses. Routine breaking of red lights, cycling wrong way on one way streets etc

  10. Missing the details on fatal collision involving Asian man on the grand canal (original ghost bike but I can’t recall the location)
