There are a lot more bikes sharing the road with cars in Denver, which has created an increasing number of conflicts and collisions on the street. We wrote about the worst crash of 2012 in this week's feature, "On a Roll," which explores the growth of Denver as a bike city. Here, we give you the twelve worst intersections for bike-vehicle crashes in Denver over roughly the last decade.

We recently took an in-depth look at how crashes have been increasing and who is at fault. But where in the city are the crashes happening most frequently? This is an important question to cycling advocates, who emphasize that better infrastructure for cyclists is one of the best ways a city can increase safety and limit conflicts and crashes on the road.

As part of our reporting for the feature, we connected with Krista Nordback, a researcher with the University of Colorado Denver who studies bike safety. In her dissertation, she analyzed bike safety and crashes locally -- and combed through Denver data to identify the worst spot for bike-vehicle crashes. As part of this effort, she identified the top intersections for crashes over a seven-year period, from 2003 to 2009. Below are the top ten spots for crashes -- although it's worth emphasizing that the data stops at 2009, and the city has greatly expanded its bike infrastructure since then.

Nordback sent us the top intersections for downtown that had five or more crashes, as well as the top ones citywide that had six or more. We've put them all in one list, with additional downtown or citywide info at the bottom.

12. Broadway and 8th Avenue: Five crashes 11. Broadway and 14th Avenue: Five crashes 10. Lincoln Street and 18th Avenue: Five crashes 9. Federal Boulevard and West 32nd Avenue: Six crashes

Continue for the rest of the list and the breakdown in Downtown Denver.

8. Lincoln Street and East 11th Avenue: Six crashes 7. West Alameda Avenue and I-25: Six crashes 6. North Washington Street and East Colfax Avenue: Seven crashes 5. Wynkoop Street and 15th Street: Eight crashes
