About

MAP: The background for the map, that shows the base roads, city boundaries, contours and geographic features, is a static picture provided by ESRI and is not an information layer, therefore it cannot be queried and a legend is not available for it. The other layers, however, are provided by the Florida Department of Transportation, State Safety Office (SSO) and do have information that can be queried. The roads layer for the current publication is based on TeleAltas version 10.2 and therefore does not always exactly align with the ESRI background. The next map update will be a change to NavTeq 2011 Q4 and should align much more closely with the background. Likewise, older analysis data that are presented on the map may have been generated on an version of the map that older than or different from the background or from the most current roads layer and so may not always align exactly with the newest map or with the background.

DATA: The information connected to the roads layer is extracted from various FDOT databases for Roadway Characteristics Inventory (RCI) and for Crash Analysis and Reporting (CAR and CLAR). The crash information are from the Crash Analysis and Reporting (CAR) database and include only long-form-reported crashes and do not currently include any short-form-reported crashes. The High Crash Segments and High Crash Intersections are the result of SSO crash rate analysis processes and are not intended to be complete or exhaustive and their inclusion here does not imply any particular ranking or limitation. The information presented on the Florida Traffic Safety Web Portal has been compiled from information collected for the purpose of identifying, evaluating or planning safety enhancements. It is used to develop highway safety construction improvements projects which may be implemented utilizing Federal Aid Highway funds. Any product displaying this notice or provided by the FDOT SSO or derived from the Florida Traffic Safety Web Portal shall be used only for the purposes deemed appropriate by the Florida Department of Transportation. See Title 23, United States Code, Section 409. Also note that the Florida Department of Highway Safety and Motor Vehicles (DHSMV) is the official custodian of the crash reports. The numbers that they report are the official numbers. The FDOT SSO maintains its own database with Long Form crash data sent to us by DHSMV, but because we have different databases and we manage the databases differently, and different technicians extract the data, the Safety Office counts are rarely an exact match with the numbers provided by DHSMV. The DHSMV, however, does not perform crash location processing.
