OTSDE, the Oregon Transportation Safety Data Explorer, is a publicly accessible, web-based GIS tool that supports ODOT safety and multi modal work, helping users see connections to leverage efforts across programs. OTSDE uses ESRI Web AppBuilder functionality to provide a user interface that does not require ArcGIS skills to view and filter crash data, crash screening data, and active transportation data. The main capabilities of OTSDE are:
- Visualize Corridors
- View Active Transportation Data
- Filter Crash Data
Critical Rate Calculator: The calculator performs crash rate analysis and identifies priority intersections or segments for further safety analysis. For information on how to use this spreadsheet, see Chapter 4 of the Analysis Procedures Manual Version 2.
Excess Proportion of Specific Crash Types Calculator: The tool performs statistical analysis to calculate a probability of specific crash types exceeding a threshold proportion. For information on how to use and interpret this spreadsheet, see the instructions packaged with the spreadsheet and Chapter 4 of the Analysis Procedures Manual Version 2.
