Orange County Dangerous Intersections and Accident Statistics

Bisnar Chase has compiled and sorted through a huge amount of data from the SWITRS (State-Wide Integrated Traffic Reports System), which is an online database of traffic incidents that take place in California. We aim to display key data about the most dangerous intersections and streets in Orange County to provide an awareness of specific dangers to motorists, pedestrians, and bicyclists within Orange County.

The first set of statistics listed below refer to the intersections and streets in Orange County with the most auto accidents from 2015-2019. All intersection data refers to accidents resulting in injury or fatality, occuring within 200 feet of the listed cross streets. Data for the OC streets with the most accidents includes crashes of all kinds, whether or not they resulted in injury.

Insights from Intersection Accident Data

Traffic volume and speed is key

We can take plenty of insights from the Orange County street and intersection accident statistics collected above. Some of the details revealed might be expected, while others are surprising.

We can see that the top-10 intersections with the most accidents are located across five different cities: Anaheim, Santa Ana, Fullerton, Huntington Beach, and Costa Mesa. These cities are among the top-8 cities in Orange County in terms of population. It stands to reason that busier areas with greater traffic volumes would have more accidents.

For example, the intersection of Edinger Avenue and Beach Boulevard, in Huntington Beach, is joint second in terms of accident numbers and top of the table of most injuries. This area sees a huge volume of traffic, sitting next to a major shopping area, as well as the on/off ramps of the I-405 freeway at its main entrance to the city. It is no wonder that such intersections become accident black spots.

In terms of fatal collisions, our statistics show that many occur on or near freeways. Crashes are common at freeway entrances and exits, due to the high speeds of vehicles, as well as drivers attempting to merge across lanes or enter traffic. When crashes occur at high speeds, fatalities are far more common.

Our analysis of the streets with the most total accident numbers also reveals a numerical correlation. Streets such as Harbor Boulevard and Beach Boulevard feature prominently on this list, and these are major roads spanning dozens of miles through the heart of Orange County. It is natural that these longer roads will be hit by higher accident counts.

Many roads across the U.S. are built in straight lines, in gridded formats. This is the case in most areas of Orange County too, and most accident hotspots occur in these gridded areas. It is interesting to note that some of the newer areas of Irvine were built with deliberately curved streets to naturally slow traffic and prevent accidents. While Irvine has the third highest population in Orange County, it does not appear on any of the lists above.

Orange County City Data

Cities with the Most Accidents Per 1,000 People

This table provides a reference for how likely residents are to get into a car accident in certain cities. We calculate this by showing the accident rate per 1,000 people in the city’s population, rather than by total number of accidents.

Under this method, Seal Beach is at the top of the list with an accident rate almost 9x that of Aliso Viejo.

Why do we rank cities by accidents/1,000 people?

The city with the most accidents in Orange County is Anaheim, with 11,580 accidents from 2015-2019. That is to be expected, as Anaheim also has the highest population of any OC city, with 349,964 residents.

We work out how many accidents occur per 1,000 people because this produces statistics that are not purely dominated by volume, and give us a clearer understanding of how likely car accidents are in certain areas.

Conclusion

This data is provided as a service to Orange County road users to show some of the driving dangers across California. The statistics show a huge range of road risks that can vary by city, population size and density, hours of the day, and more. We also break down specific streets and intersections with in-depth accident figures, DUI figures, and much more. It shows that DUIs make up a small percentage of the total accident numbers, and are in a slight general decline, but are responsible for almost as many deaths as car accidents not involving alcohol or drugs.

It is not a shock that the longer roads see more accidents, or that a large percentage of fatalities occur near freeway ramps, due to the greater speeds causing collisions of higher impact. But some of the most dangerous intersections in Orange County might come as a surprise. In some cases, these dangerous intersections might simply feature a higher volume of traffic, causing more accidents. Others may have confusing layouts or a lack of visibility.

We hope that these statistics serve as a valuable resource to Orange County drivers. Feel free to use or cite the statistics; please attribute them to Bisnar Chase and link back to this page.
