Effective Monday, July 13th UDOT has made the following updates to their data in Numetric.
2019 Data, and Real-time Data Feed
Effective Monday, July 13th, all 2019 crash data has undergone the standard quality control process and is reflected in Numetric.
Additionally, Numetric has now established a near-real-time data connection to the UDOT crash database. Each night, Numetric will receive updated crash record data from UDOT, meaning crash data will be available in Numetric within a day of the data being submitted by the responding officer. This means that current year data will be more complete than it ever has before.
Note: Because each crash record goes through a quality control process that incudes geo-location data, caution should be exercised when using recent crashes (within the last 30 days), as that data has not gone through the quality control process. Recent crashes should be used for information only and not used in decision making.
New Filters
With the new data connection, several new filters are available in Numetric, including:
1. Full Route Name - this field now lets you filter more precisely for ramps, P or N directions, and milepoint ranges on all routes.
2. Geographic Filters:
MPO - Allows you to filter based on MPO boundaries
Metro Area - this is based on census definitions, it provides a good option for filtering specific urban and rural areas
Area Type - this is a generalization of the metro areas, classifying each as an Urbanized Area, Urban Cluster, or Rural.
3. Crash Filters
Wrong Way Driving
Adverse Roadway Surface
Train Involved
Transit Vehicle Involved
Right-Turn Involved
Left-Turn or U-Turn Involved
Work Zone Involved
Animal Related
Holiday Crash - Allows you to filter to specific holidays, date ranges are built-in so you automatically get all crashes that occurred during the holiday period, for example it would include Friday-Monday for a Monday holiday.
Heavy Truck Involved - Because the “Commercial Vehicle Involved” filter includes small commercial vehicles, this filter can be useful when you are looking only for large/heavy vehicles.
Countermeasure Changes
With the new data connection, changes have been made to various countermeasures. The following changes have been made:
Removed
Wildlife Warning Sign - This is redundant with the Wild Animal, Domestic Animal, and Animal Related filters so it was removed. Those filters can still be used to identify animal crashes for analysis.
Bicycle Warning Sign - This was removed in favor of the new “Active Transportation Improvement” countermeasure that accounts for pedestrian and bicycle involved crashes.
Added
Active Transportation Improvement - This is a generic countermeasure for any type of active transportation improvement. Careful review of the crash data and site conditions are required to determine the best treatment.
Adjusted or Renamed
High Friction Surface - formerly “Friction Improvements”, the criteria were also adjusted.
Roundabout or Signal - formerly “Traffic Signal”, the crash criteria for either countermeasure are the same so we wanted to highlight that both are viable options and should be considered.
Raised Median - formerly “median treatment”, we found this was being confused with other options, the name was adjusted for clarity.
Saved Queries
All saved queries are migrated, but because many fields have changed not all filters will work. Filters that align directly with fields in the new release are maintained, filters that are no longer available will be shown as gray in the search bar. Any filter showing grayed out will need to be removed and applied using the new or adjusted filter. Any grayed out filter will not be applied to any saved query.
