11. Photo Log Collection: Very accurate GPS Other data being collected when route driven Safer Urban collection Link to Object photo saved in database No travel time to collect objects from available data KYTC Photo Log

12. Collected Inventory

13. Manual Collection: Area Development Districts contracted to collect data Data stored in shapefile and geodatabase Merged with Photo Log database KYTC Manual Collection

16. Crash Data Transportation

18. H igh C rash I ntersections  Intersection list  Intersection ADT  Assign intersection crashes  Calculate intersection crash rates  Identify high crash intersections

19. KY 29 US 68

20. I ntersection L ist  A spatial database was created for the list of intersections  The database included the roadway characteristics of the major road for each intersection

21. Intersection of US 25 and US 27 This record would contain US 25’s roadway characteristics

22. I ntersection ADT  Traffic volumes were obtained from the Highway Performance Monitoring System (HPMS) database  The ADT of all intersecting roads was added to the intersection list  This was accomplished spatially using ArcView  Each intersection had up to five ADT sections

25. Crash Locations  Methods for locating a crash for a police officer  Review of a random sample of crash data  Analysis of current location data  Where should a crash be located?  Conclusions / Recommendations

26. Paper Reports  Submitted manually  GPS from Magellan, Google® Maps, 911 system  County, Route and Milepoint (CRMP) using reference system

27. eCrash KYOPS  MapIt  Added October 1 st 2007  CRMP data linked to GPS  Between/Intersect streets  Searchable  RT Unique: “034-US-0068 -000”

28. Crash Data Potted by GPS

29. Crash Data plotted by GPS Showing County Check

30. Kennedy Bridge Study

31. Crash data plotted by GPS and CRMP within proximity to the “Kennedy Interchange corridors”

32. Crashes occurring outside the buffer zones were selected due to their location description or using engineering judgment

33. EPDO Density Plots for the “Kennedy Interchange Corridors” (2005 to 2009)

34. EPDO Density Plots for the I-64 and I-65 section of the “Kennedy Interchange Corridors” (2005 to 2009)

35. Travel Data Transportation, Planning, …

36. Travel Time Study  Purchased travel time/speed data from NAVTEQ  Setup ArcServer to display travel speed data using Tracking Analyst  Uploaded data to ArcGIS.com for interactive viewing
