The following filters have been created to help identify crashes identified as related to one of the TxDOT Strategic Highway Safety Plan emphasis areas.

It is important to note that when reporting on SHSP Emphasis Areas, TxDOT best practice is to only include crashes from the last full five years of data, as well as K (fatal), and A (suspected serious injury) crashes in your reporting.

Each of the SHSP Emphasis Area filters, and a detailed breakdown of how those crashes are identifed, is provided below.

Emphasis Area Filters


SHSP Impaired Driving

The following logic is used to determine if crashes are considered Impaired Driving:

IF

TxDOT Reportable = True

AND

Unit Description = Any of the following (Motor Vehicle, Motorized Conveyance, Non-Contact)

AND

Alcohol Test Result = Positive

OR

Drug Test Result = Positive


SHSP Intersection Related

The following logic is used to determine if crashes are considered Intersection Related:

IF

TxDOT Reportable = True

AND

Intersection Related = Any of the following (Intersection, Intersection Related)


SHSP Distracted Driver

The following logic is used to determine if crashes are considered Distracted Driver:

IF

TxDOT Reportable = True

AND

Contributing Factors = Any of the following (Distraction In Vehicle, Driver Inattention, Cell/Mobile Device Use - Talking, Cell/Mobile Device Use - Texting, Cell/Mobile Device Use - Other, Cell/Mobile Device Use - Unknown)


SHSP Occupant Protection

The following logic is used to determine if crashes are considered Occupant Protection:

IF

TxDOT Reportable = True

AND

Person Type = Any of the following (Driver, Passenger/Occupant)

AND

Person Restraint = None


SHSP Speed Related

The following logic is used to determine if crashes are considered Speed Related:

IF

TxDOT Reportable = True

AND

Contributing Factors = Any of the following (Unsafe Speed, Speeding - (Overlimit), Failed Control Speed)


Vulnerable Users

Note: Vulnerable Users are often broken into two categories: Pedestrians, and Pedalcyclists, However, Motorcyclists are sometimes considered in this population as well. These numbers are not typically combined into a single value but rather reported independently.

SHSP Pedalcyclist (VRU)

The following logic is used to determine if crashes are considered Pedalcyclist (VRU):

IF

TxDOT Reportable = True

AND

Person Type = Pedalcyclist

SHSP Pedestrian (VRU)

The following logic is used to determine if crashes are considered Pedestrian (VRU):

IF

TxDOT Reportable = True

AND

Person Type = Pedestrian

SHSP Motorcycle (VRU)

The following logic is used to determine if crashes are considered Motorcycle (VRU):

IF

TxDOT Reportable = True

AND

Person Type = Any of the following (Driver of Motorcycle Type of Vehicle, Passenger/Occupant on Motorcycle Type Vehicle)


SHSP Roadway and Lane Departures

Note: the Roadway and Lane Departure values are a combination of Roadway Departure, and Head-On - Wrong Side No Pass crashes, which are defined below:

Head–On - Wrong Side Not Passing

The following logic is used to determine if crashes are considered Head-On - Wrong Side Not Passing:

IF

TxDOT Reportable = True

AND

Manner of Collision = Opposite Direction Both Going Straight

AND

Contributing Factors = Wrong Side - Not Passing

Roadway Departure

The following logic is used to determine if crashes are considered Roadway Departure:

IF

TxDOT Reportable = True

AND

Roadway Relation = Any of the following (Off Roadway, Shoulder, Median)

AND

Manner of Collision = Any of the following (One Motor Vehicle - Going Straight, One Motor Vehicle - Other)
