Description:
Abstract:
This data set contains crash rate analysis data based on 5 years of long form crash reports located on the State Highway System (SHS) and analyzed by location based on the rate of crashes per Million Vehicle Miles (MVM), which is a length-weighted accumulation based on the Annual Average Daily Traffic (AADT) figures from the FDOT Roadway Characteristics Inventory (RCI) database for each of the years included in the study.
Purpose:
The FDOT GIS Basemap Routes feature class provides spatial information on Florida Basemap Routes, as well attribute information compatible with the Roadway Characteristics Inventory (RCI) database. Furthermore, the spatial data also contains measures (m-values) that can be used for event mapping. The crash rate analysis data is intended for use in targeting safety improvements.

Process_Description:
This dataset was created using ESRI event mapping. The route system is the Transportation Statistics' basemap routes. The event source is an oracle table that is created with the following query: select * from roadway The conversion of these events into a shapefile includes specifying the shapefile geometry should contain measure values (M-values) which means that this dataset may be used as a route source for subsequent event mapping of tabular data that contains a roadway identifier and milepost information that complies with the Florida Department of Transportation's Roadway Characteristics Inventory (RCI) milepost logic.

Distribution_Liability:
The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist.
Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement.

A note about data scale:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger.
Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our webpage at: <http://geoplan.ufl.edu/education.html>
