Analyzing the Data for LHSIP

Analyzing Data for LHSIP

Five years of crash data is used to identify the jurisdictions with the highest amount of Fatal and Serious Injury (Type A) crashes. Eligible jurisdictions are identified and notified by LHTAC in the fall. Eligible jurisdictions should analyze the crash data using the following steps:

  1. The crash data is available online.
  2. Once you have accessed the site, select your ITD District, and then your jurisdiction in the upper left corner.
  3. The map will zoom to your Local Highway Jurisdiction and the crashes can be viewed. You may select an individual crash or using the mouse, select a group of crashes. Crash information will display below the map.
  4. You may sort your crash information by selecting any of the headings.
  5. You may apply additional filters to crash data by selecting “Advanced Filters” from the top left corner.(If assistance is needed, please contact LHTAC.)
  6. Determine the type of crash you would like to address with your improvement.
  7. Count the amount of each type of crash severity, in desired area/location of safety improvements (Fatal, Type A, Type B, Type C, Property Damage Only (PDO).
  8. Using your experience, area knowledge, and the FHWA Crash Reduction Factor Toolkits or CMF Clearinghouse, select a Crash Reduction Counter Measure and Crash Reduction Factor (CRF) for the area/location you have chosen to address. You may propose implementing more than one Counter Measure in an area. The CRFs will be added together but are capped at a total CRF of 60% (will automatically add and cap at 60% on application).

We highly encourage you to look at systemic (grouped location or corridor) improvements rather than single site locations. Example: Using crash data at one intersection and applying improvements to multiple intersections with the same characteristics.

If you cannot determine what counter measure is appropriate, please contact LHTAC for assistance.

A small amount of funds may be used for Road Safety Audits (RSA). Contact LHTAC to discuss your potential RSA application prior to submittal.
