Alcohol, Speeding, Bicycle Related Collision Data from State Traffic Safety Office

Here is data on alcohol and speed related collisions, as well as collisions involving bicycles, from 2006 to 2010.

The California Office of Traffic Safety updated its Collision Rankings to include 2010 data, the most recent available, and reports say traffic fatalities are the lowest they've been since 1944.

Below is data pulled from OTS's collision rankings from 2006 to 2010. It includes data on alcohol and speeding related collisions as well as collisions involving bicycles.

Danville falls into Group D: cities with populations between 25,001 and 50,000. There are 93 cities in Group D this year. A No. 1 ranking represents the worst and a 93 the best.

The data breaks down the rankings between two categories based on rates of fatal and injury collisions per “1,000 daily-vehicle-miles-of-travel" (Caltrans data) and per “1,000 average population" (Department of Finance data) figures.

Alcohol related collisions

Collisions (in raw numbers) where alcohol was involved are fairly consistent through the years. The town's best year was in 2008 when only three collisions were alcohol related.

As far as rankings go, Danville has been dropping since 2008. The town ranked 92 (miles traveled) and 91 (average population) out of 97 in 2008 for alcohol related collisions. In 2010, it dropped to 76 and 67 out of 93. Though the drop in rank is large, the raw number of collision was relatively small, from 3 collisions in 2008 to 8 in 2010.

Collisions involving bicycles

Again, Danville's raw numbers have been consistent through the years for collisions involving bicycles, ranging between 12 and 15 collisions from 2006 to 2010. Rankings have also been fairly consistent, albeit low. Danville ranks in the bottom half of all Contra Costa County cites nearly every year in both categories.

Speeding related collisions

More consistency here, in both raw numbers of collisions and rankings, with the exception of 2006 when collisions were nearly double that of each year after.

There were 25 collisions where speed was a factor in 2006. Between 2007 and 2010, collisions ranged between 10 and 15 only. The lowest number came in 2010, where 10 speed-related collisions were recorded.
