Additional CMAT Help

Map Corrections or Ommissions

    In order to make the locaton of the roads match the location of the crashes, we are using an older version of the roadway map that best matches the location of the crashes. If you see errors or ommissions in the base map, they may have already been fixed. If you have corrections, please contact Michael Clement in the Office of Transportation Data, michael.clement@dot.iowa.gov, 515-239-1826.

Speed Limits and Volumes

    When you zoom in close to the roads, two numbers will appear. These numbers are the speed limit in miles per hour and Average Annual Daily Traffic in vehicles per day as estimated for the 2004 DOT base map. These volumes are estimated and based on a limited number of counts that were taken sometime between 2001 and 2004. For more detailed traffic volume information go to City and County AADT Maps.

Stacking Severity Colors

    When stacking crashes, the colors correspond to crash severity as follows:

    severity colors shown

    This can also be seen by turning on the crash severity filter in CMAT.

Printing and Exporting

    Some items such as maps, charts and reports can be exported or printed directly from CMAT in a pre-determined format. If you would like more flexibility with what gets printed, or would like to export something from CMAT into a report or presentation, we recommend using "Print Screen." Additional guidance is available in Exporting to MS Word or Powerpoint .

Manual

    We do not currently have a user manual for CMAT. However, instructions for several of the functions in CMAT can be found in the manual for the Incident Mapping Analysis Tool, IMAT Manual (1.9 MB).

Training

    Information about requesting CMAT training is at CMAT training.
