Flashing Makes You Cross

Last summer, many Boulder residents were upset about pedestrian-activated flashing signs. A driver ran into a family of three cycling through a PAFS crosswalk, sending a 7-year-old boy to the hospital. Shortly thereafter, Boulder transportation operations engineer Bill Cowern told the media that the rate of accidents at several of these crosswalks had increased.

Although Cowern also stated that accidents had decreased or stayed the same at some crosswalks, and that the increase couldn't be interpreted without the completion of a study underway at the time, many called for the removal of these devices.

That study was completed and presented to the Transportation Advisory Board late last year and to City Council earlier this month.

The good news from the study is that PAFS crossings are no more dangerous than other signalized crossings in the city. This, when combined with the finding that they significantly increase both usage by pedestrians and yielding to pedestrians by drivers, shows that they are a valuable addition to the city's arsenal.
