Which are the most dangerous routes for cyclists in Cardiff?

Is it possible to get an idea of where cycle provision is failing in the city - and which are the blackspots for cyclists and which routes prove most pleasurable?

We've teamed up with yourCardiff to show the most favoured and most dangerous routes for cyclists in the city. YourCardiff have been plotting submissions from people's favourite cycling routes onto the map – and we have been busy plotting serious cycling incidents as well as the top most potholed roads - which came out of this freedom of information requst. So we should get an idea of any real blackspots for cyclists.

On the map, you'll find the red lines represent the best cycling routes in Cardiff, and the red caution signs indicate where an incident has happened in the last five years – in which the road incident involved a cyclists. See the full data set for the incidents here.

Out of these incidents two are recorded to have been caused by poor road conditions - one on Sophia Close in Riverside, and Vaendre Lane in Pontprennau. You can see the data for these two incidents here.

In 2008, 94 collisions where a cyclist involved were recorded, nine of which were rated serious and the rest slight – there were no fatalities.

The map also shows the top 21 most potholed roads in Cardiff – which also came out of the freedom of information request and you can see my earlier post on this here.

The council revealed 8,850 potholes in the city had been filled in the last year – and gave figures for the potholes reported in each ward area. You can report potholes on your road by using our Fix My Street tool here.

As part of the council's Sustainable Travel Initiative cycle routes in Cardiff are planned to be improved in the next three years – alongside the OYBike scheme which hopes to encourage more bike users in the city.

Cardiff Council said:

The provision of good quality cycling facilities, both on road and off road, can help to increase cyclists' safety by reducing the risk of collisions with vehicles. Good facilities can also help to encourage more people to take up cycling. Evidence from research indicates when numbers of people cycling increase, the rate of casualties decreases
