Users should direct questions concerning these programs to their information resource administrator or to the Traffic Operations Division (TRF).

Booklets that guide users step-by-step through the process of obtaining these RJEJCL reports are available from TRF. Users should ask for any or all of the following:

  • “How to Obtain a Master Accident Listing”
  • “How to Obtain a Section Collision Plot Diagram”
  • “How to Obtain an Intersection Collision Plot Diagram”
  • “How to Obtain a RRR Report”
  • “Traffic Accident Records System.”

NOTE: Since the Texas Department of Public Safety (DPS) is the agency of record for traffic accident information, requests for information from the general public should be routed to DPS. However, when TxDOT is required to produce traffic accident information, the Master Accident Listing is the standard report provided.
