Sebastopol Road at Stony Point Road: Santa Rosa's top intersection in reported collisions. Road Warrior photo

Planning to drive through the intersection of Stony Point and Sebastopol roads in Santa Rosa? Better be careful. It again ranks No. 1 in the city for highest number of reported collisions.

The Roseland-area intersection racked up 16 collisions last year, twice that of 2011 when it tied for sixth place but down from 20 in 2010 and 19 in 2009 when it ranked No. 1 for both years.

2011′s No. 1 — Highway 12 at Mission Boulevard — fell last year to a tie for second place with Santa Rosa Avenue at Hearn Avenue, each with 11 collisions.

Each year recently, the Police Department’s traffic unit puts out a list of 25 intersections with the most reported collisions. Then each week during the year, officers in the traffic unit typically spend part of their day at one of the intersections, looking for traffic violators, with the idea of trying to make them safer.

The list of 25 is based on the number of collisions in which police took a report. If a crash was minor and the drivers didn’t seek a police report, it was not counted. And the list doesn’t factor in the number of cars going through each intersection, so the intersection where you scientifically stand the greatest chance of getting hit may be some other one. Regardless of that, these 25 intersections are dangerous and you should be careful at them.

Officer Jeff Adams, who oversees the traffic unit’s extra enforcement operation at these intersections, said he hadn’t reach any conclusion on why Stony Point at Sebastopol had so many collisions.

Here’s the list of 25:

No. 1

–Stony Point Road at Sebastopol Road, with 16 collisions. Tied for 6th in 2011 with 8 collisions. After spending just a few minutes during the lunch hour a day this week, we saw two cars run the red light and a couple turn right on red without even stopping, and that was just southbound Sebastopol. Readers have written in to say traffic violations are even worse during commute hours.

    So basically, every major intersection.

    These stats should be recalculated for number of accidents per number of vehicles traveled in the intersection – this would give a “per capita” accidents per intersection.

    PLEASE; you have knowledge of who to contact. Highway 12 at Mission again today saw a driver making a left turn from northbound Mission to west bound Hwy.12. From the 2nd lane. Fortunately he was waiting for the green arrow. The light was green for through traffic and he just sat there, blocking the thru traffic. I have seen a number of times cars go left on the red arrow because the thru light was green. Again please advise the powers that be they need street and overhead direction markings and signage. Someone is going to get killed if drivers keep doing this.

    Stony Point @ Sebastopol Road is #1 because EVERYONE runs the red light. If the city decided they wanted to install red light cameras there they would make a bundle. I pass through there four days a week & it’s frightening. You wait & pause & wait some more when the light finally turns green. Even placing a cop there during commute hours would help.

    Most of the violations at Stony Pt & Sebastopol Rd that I’ve seen would be non existent if the yellow light would stay lit longer. You can’t even get halfway through the large intersection when it goes from green to yellow in 1.5 seconds…

    The list is good information but the real question is what the city is going to do about it? Enforcement can only do so much. Evaluate and change the pattern of traffic should be the key!

    Boy, Steele Lane @ County Center Drive (Armory) is a cluster if I have ever seen one.

    Also the light at Brush Creek at Montecito Dr. (Fountain Grove) is THE WORST. It seems to always be red for the E/W traffic. Are they doing this to slow down and stop the traffic coming off the hill?

    There isn’t an overall tone of enforcement. People only do it because they understand from their own personal experience that they can get away with it. Install ticketing cameras at intersections. Hit people in their pocketbooks.

    please install working cameras to all intersections to cite red light runners! Think of the money the county would make and hopefully curb the red light running. I watch people purposefully speed up to “make it” in time. Only to put my life, and those in my car, at risk!
    I would guess that they majority of accidents was caused by red light runners, very disappointing.

    I can not believe that the speed limit laws in Santa Rosa are ignored to such a high level. It is not unusual for someone to be driving at 50 mph down Guerniville Rd. Every where you drive in the city the speed limit are not observed. If people slowed down there would be less accidents. Santa Rosa police should start ticketing the speeders.

    Fix the timing or intelligence of the lights in the city. Nearly everyone runs red lights because the timing is obsurd. It’s bs to be on a main road and have the light cycle red when there is no cross traffic. How about lights turning red to cycle turn lanes when there is no one at the turn lanes. I’ve lived in quite a few places and never seen such systematic obsurdity when it come to traffic lights.
    If the lights were smarter, far fewer people would see any incentive to running a red light.
