Data Disclaimer

Missouri and Kansas report crash data in different formats. When reflecting transportation safety issues in metropolitan Kansas City, it can be difficult to generate the same level of data for both Kansas and Missouri jurisdictional boundaries. MARC is currently working with this data and reporting information that will provide insight into transportation safety issues in the region. However, the data cannot be guaranteed accurate and error-free. When using transportation safety information provided by MARC, either online or in document format, it is important to keep these sources of potential error in mind:

  • Data is reported differently by each state, so analyzing some safety trends and issues can be difficult.
  • The reports compiled by law enforcement agencies are of a high quality; however, the data in these reports are subject to human error.
  • Many of the crash reports are coded or manually keyed into computer programs from the crash reports, creating another point of potential error.
  • Not all crashes are reported to law enforcement agencies. Crashes involving very little property damage and no injuries are likely to be underreported.
  • Crashes on private property, off of public roads, are unlikely to be reported.

Due to these reasons, MARC cannot make claims to the accuracy of the data. Some discrepancies will be found in the number of reported crashes when comparing this information with the Fatality Analysis Reporting System (FARS), the General Estimates System (GES), the National Transit Database (NTD) and the Commercial Vehicle Analysis Reporting System (CVARS). Over time the compilation and accuracy of traffic safety data will increase with advanced training and new technology. These improvements will contribute to a greater knowledge of transportation safety in the Kansas City region.

MARC thanks the states of Kansas and Missouri for providing this information, as well as individuals that have assisted in gathering and analyzing this data.
