Introduction

The Statewide Integrated Traffic Records System (SWITRS) is collected and maintained by the California Highway Patrol (CHP). SWITRS contains all collisions that were reported to CHP from local and governmental agencies. For more information regarding SWITRS or for detailed summaries by year, please visit the CHP website at: https://www.chp.ca.gov/programs-services/services-information/switrs-internet-statewide-integrated-traffic-records-system. You can also download complete datasets and request statistical reports via the I-SWITRS application provided by CHP at: http://iswitrs.chp.ca.gov. 

If you are interested in SWITRS collision rankings of cities or counties without investigating the actual datasets, the California Office of Traffic safety has an excellent resource at: http://ots.ca.gov/Media_and_Research/Rankings/default.asp. Their site allows you to choose a county or city and see collision 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 2015 SWITRS Annual Report on CHP SWITRS website yet so we say provisional for 2015 and later dataset.


Working with the relational database structure

The data have a hierarchical structure.  The collision tables contain information on each collision, one line per collision.  The party tables contain information from all parties involved in the collisions, one line per party.  Parties are the major players in traffic collision - drivers, pedestrians, bicyclists, and parked vehicles.  The information includes personal descriptors and vehicle descriptors.  The victim tables contain 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, COLLISION, PARTY, and VICTIM are entities that have very specific relationships to each other.  COLLISION is a “strong” or “parent” entity because it is can exist on its own.  PARTY is a “weak” or “child” entity, because it logically depends on an instance of COLLISION.  In other words, a driver cannot be a party in a collision unless the collision exists and is in the collision 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, age, and vehicle make.  VICTIM has 7 variables: case id, party number, sex, age, victim type, seating position, and seat belt status. 

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 caseid 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, caseid and parnum, 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-level table or a victim-level 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.
