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.

Accident Breakdown

Pedestrian Accidents By City

With a relatively small population and a high amount of tourist foot traffic, it is no surprise that Laguna Beach tops the list of cities with the most pedestrian accidents with a significantly higher rate than other areas in the top 5.

The safest cities for pedestrians include Villa Park, Yorba Linda, Cypress, and Aliso Viejo. These are all areas on the lower end of the population scale, leading to a lower rate of traffic and foot traffic than many other Orange County cities.

Motorcycle Accidents By City

There are no major correlations with the cities reporting the most motorcycle accidents by population, but Seal Beach takes the top spot by a considerable margin, with a high number of motorcycle accidents every year.

Once again, the lower population areas dominate the safer city rankings when it comes to motorcycle accidents. The bottom 5 locations have very low adjusted and actual accident numbers.

Bicycle Accidents By City

The cities presenting the highest dangers to cyclists are Newport Beach and Huntington Beach. This is unsurprising, as the two cities are cycling hotspots in Orange County. A huge number of people ride their bikes around the beachfront areas.

Newport Beach has particularly high bicycle accident numbers. In Newport, cyclists can move from the beachfront promenade to high-traffic areas very quickly, leading to more accidents and several fatalities.

Truck Accidents By City

In general, a higher daily average of truck traffic through a city correlates with a higher occurrence of truck accidents. Anaheim, Santa Ana, and Irvine have the highest accident numbers, but the much smaller city of Brea has a greater population adjusted rate.

Larger cities have a massive number of trucks driving in or passing through every day. The smaller cities, with far fewer deliveries and truck traffic, are shown to have drastically lower crash numbers year on year.

Accidents By Year

Over the following section we will examine data from all Orange County cities, sorted by year, and using a six-year sample period spanning 2014-2019. The data will cover car accidents resulting in injuries and fatalities only.

Over this period, accident numbers have risen and fallen in waves. The number of auto accidents in Orange County peaked in 2016. In fact, the number of accidents dropped by 14.3% between 2016 and 2018. But there are always outliers, and some of the cities with rising numbers between 2014 and 2019 are shown in the graph below.

The numbers recorded here for 2019 are the lowest to date by some distance. However, it should be noted that as the latest data available, this trend could be a result of incomplete records for 2019.

DUIs by Year

More information about DUIs

Driving under the influence of drugs or alcohol will greatly increase the chances of a crash occurring, due to the driver’s compromised reflexes and decision making.

The number of DUI accidents resulting in injuries or fatalities in Orange County peaked in 2016. However, it should be noted that 2016 was a statistical outlier, with a much higher number of total accidents than normal in OC.

In general, the number of DUI accidents has been on the decline since 2016. But the percentage of overall accidents caused by DUI has held steady in the 9-10% range, pointing to little improvement in awareness of the consequences of driving under the influence.

Year DUIs Total Accidents % of Accidents
2014 1360 13901 9.8%
2015 1374 14899 9.2%
2016 1418 16054 8.8%

Accidents

According to the Orange County DUI accident data collected here, a fatality will occur in more than 5% of DUI crashes (compared to less than 1% in which drugs or alcohol are not a factor). The chances of a fatality occurring in a car accident increase by an enormous 486% when at least one of the drivers is operating their vehicle while under the influence of alcohol or drugs.

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.

There are a lot of cars on the road in Orange County and across Southern California, and accidents are common. If you have been involved in a collision and need legal help, contact the expert car accident lawyers of Bisnar Chase. Call (800) 561-4887 or email us now.
