Learning Objectives
1. Understanding the importance of data analysis of
crimes, crashes, and traffic enforcement
2. Highway Safety Operations Center’s (HSOC) role in
trend and statistical analysis
3. Proactive law enforcement through collaborative
partnerships

Data Analysis of Crimes, Crashes, Traffic:
Why It Is Important
• Crimes
Occur on Texas highways every day
• Multiple times per day
• All across the State
– The ability to identify trends and patterns of crime, through
analytical processes, will be highly beneficial to law
enforcement and help to make our communities safer.
– Cooperative relationships among law enforcement agencies
with mutual information sharing is critical to success.

Data Analysis of Crimes, Crashes, Traffic:
Why It Is Important
• Crashes
Rate of frequency and locations are similar to crimes
• Pose a threat to the safety of all motorists
– Responsible for approximately 3,400 deaths per year on Texas
highways
– Responsible for approximately 65,000 serious injuries every year
on Texas highways
For Official Use Only
Data Analysis of Crimes, Crashes, Traffic:
Why It Is Important
• Traffic Enforcement
Conducted by city, county and state law enforcement
• Autonomously
• Varies from traffic violations to felony criminal acts
• Provides potential links to other crimes
For Official Use Only
Data Analysis of Crimes, Crashes, Traffic:
Why It Is Important
• Bringing It All Together
The ability to gather data regarding crimes, crashes, and
traffic stops in one centralized database, from multiple
participants, will enhance analysis.
• Trend analysis improves exponentially
• Predictive analysis becomes more viable
• Proactive law enforcement becomes reality
For Official Use Only
Highway Safety Operation’s Role
HSOC is intended to serve as a central collection point for data
related to crimes, crashes, and traffic stops on Texas highways.
– HSOC provides analytical capabilities of the raw data.
• Performs
– Trend analysis
* Identifies where the problems currently are (crimes, crashes,
specific traffic violations) and what trends are indicated
– Statistical analysis
* Provides statistics on crimes, crashes, and traffic violations for
a specified geographic area
– Predictive analysis on the horizon
* Utilizes existing data to predict future occurrences
For Official Use Only
Highway Safety Operation’s Role
Information Available to Partner Agencies
– Periodic publications of trends
• Statewide
• Regionally
– Conduct additional research by request
– Geospatial mapping
For Official Use Only
Highway Safety Operation’s Role
• Identify criminal incidents and terrorist suspects/cells utilizing Texas highways to

Using DPS and TXDOT databases, we can
analyze large data sets in order to identify
possible patterns. This example highlights how
the rate of serious injury crashes involving DWI
is much higher on holiday weekends.
Identifying patterns like the above example can better
assist both state and local law enforcement to develop
strategies to combat traffic issues.

Special Holidays and
Events encompass about
8.49% of the days in a
year. However, 13.46% of
fatal crashes attributed to
DWI occur in that small
timeframe.
The average number of
fatal crashes per day on
holidays has not only been
approximately 1.53 crashes
higher in the previous 5
years, but has increased
year by year since 2010.

Data can be analyzed at the statewide level, as well as broken down by specific region, district
and area. As the above chart shows, further breakdown can reveal what days (and times, if
necessary) that incidents are commonly occurring. This concentrated level of analysis can help
officers make more informed tactical decisions.
