Introduction

The Statewide Integrated Traffic Records System (SWITRS) consists of data collected and maintained by the California Highway Patrol (CHP). SWITRS contains all crashes that were reported to CHP by local and governmental agencies. For more information regarding SWITRS or for detailed summaries by year, please visit the CHP website. You can also download complete datasets and request statistical reports via the I-SWITRS Website provided by CHP.

If you are interested in SWITRS crash rankings of cities or counties without investigating the actual datasets, the California Office of Traffic Safety (OTS) has an excellent resource at: OTS Crash Rankings. Their site allows you to choose a county or city and see crash rankings by total count, vehicle miles travelled, or by average population.

Final vs Provisional

We determine the dataset is final when we process the data after CHP announces the report of the specific year. CHP hasn't released the 2023 SWITRS Annual Report on CHP SWITRS website yet so we say provisional for 2023 and later datasets.

Working with the relational database structure

The data have a hierarchical structure.

The CRASH table contains information on each crash, one line per crash.
The PARTY table contains information from all parties involved in the crash, one line per party. Parties are the major players in a traffic crash - drivers, pedestrians, bicyclists, and parked vehicles. The information includes personal descriptors and vehicle descriptors.
The VICTIM table contains information about the victims - persons associated with each party. For example, a motorcyclist and his passenger are each a victim. Injury severity is included in the VICTIM table.

The victims can be thought of as being nested within parties and parties can be thought of as being nested within crashes. Another way to conceptualize the data is to use the entity-relationship model common in relational database management systems. In this data model, CRASH, PARTY, and VICTIM are entities that have very specific relationships to each other. CRASH is a “strong” or “parent” entity because it can exist on its own. PARTY is a “weak” or “child” entity, because it logically depends on an instance of CRASH. In other words, a driver cannot be a party in a crash unless the crash exists and is in the crash table. Likewise, VICTIM is a weak entity, because it depends on PARTY for its existence.

The figure shows an example database with CRASH, PARTY, and VICTIM tables. The database is tiny – it only contains information on 2 crashes. CRASH has 3 variables: CASE ID, DAY OF WEEK, and COUNTY. PARTY has 4 variables: CASE ID, PARTY NUMBER, PARTY AGE, and VEHICLE MAKER. VICTIM has 7 variables: CASE ID, PARTY NUMBER, VICTIM GENDER, VICTIM AGE, VICTIM ROLE, VICTIM SEATING POSITION, and VICTIM SAFETY EQUIPMENT.

The relationships between each pair of tables are represented below. It is important to understand the relationships when merging tables. The rectangles represent data tables; the arrows and accompanying text describe the relationship. In the CRASH - PARTY relationship, the records are linked with the CASE ID variable and any number of PARTY records can be associated with a crash. The PARTY - VICTIM relationship tells us that the linkage require two variables, CASE ID and PARTY NUMBER and that any number of victims can be associated with a party.

An important aspect of the relationship between the PARTY and VICTIM tables is that some parties (i.e., drivers, bicyclists, pedestrians) will also appear in the VICTIM table. Injured parties will appear in the VICTIM table; uninjured parties will not.

A common way to work with data of this structure is to create a PARTY table or a VICTIM table that has data from all its parents joined to each row. For example, if you plan to do analyses at the victim-level, you can start with a VICTIM table and join in values from corresponding PARTY and CRASH tables. In the figure, the CRASH variables and the PARTY variables are joined to the VICTIM table. Doing so provides a victim-level table that can be summarized (for example, count or sums can be generated), while considering PARTY or CRASH variables. You must keep in mind that the PARTY and CRASH variable will repeat for as many victims as there are.

New Level of Victim Degree of Injury New

CHP has added three additional classifications of injury status based on the Model Minimum Uniform Crash Criteria (MMUCC) 5th Edition released in 2017. The MMUCC is a standardized method for reporting traffic crashes and the vehicles, persons, and environment involved.

New Victim Degree of Injury	Old Definition of Victim Degree of Injury
5 - Suspected Serious Injury	2 - Severe Injury
6 - Suspected Minor Injury	3 - Other Visible Injury
7 - Possible Injury	4 - Complaint of Pain

For the purpose of analysis across multiple years with old definition (2, 3, and 4), we combined injury status categories using the latest definitions (5, 6 and 7); i.e., all victims coded as "Severe Injury" or "Suspected Serious Injury" are shown as "Suspected Serious Injury" in our tools.

ⁱ The data element was intended to be the population count of the city or county at the time of the crash. However, population count is time-dependent. Existing values are computed from a lookup table with no effective dates. Therefore the value cannot be accurate over time.
ⁱⁱ The column translates the value of the data element "reporting_district" in crashes reported by LAPD to a single letter. However, LAPD currently has 21 districts but the translation only covers 18 districts. Anyone wanting LAPD district can get it from the last two digits of the data element "reporting_district".
ⁱⁱⁱ The officer checks the box "state highway related" if the crash was on or near a state highway. When the box is checked, the data element has the value Y. However, if Caltrans later decides that the crash was not state highway related, the data element is changed to N, for not state highway related.
^iv These data elements are from Caltrans coding form Card 8. The values are available only on some highway related documents that were received as hardcopy and are meaningful only to Caltrans.
^v The type of roadway at the location of the crash. This column is deprecated. The value is based on CHP beat and post mile. The post mile is from Caltrans coding form Card 8 but we stopped doing Card 8 on CHP crashes in 2015.
^vi HPM 110.5 chapter 4 paragraph 28. a.
^vii HPM 110.5 chapter 4 paragraph 28. f.
^viii HPM 110.5 chapter 4 paragraph 26
