KYTC Photo Log

  • 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
slide13

KYTC Manual Collection

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

Crash Data

Transportation

h igh c rash i ntersections
High Crash Intersections
  • Intersection list
  • Intersection ADT
  • Assign intersection crashes
  • Calculate intersection crash rates
  • Identify high crash intersections

US 68

KY 29

i ntersection l ist
Intersection List
  • A spatial database was created for the list of intersections
  • The database included the roadway characteristics of the major road for each intersection
slide21

Intersection of US 25 and US 27

This record would contain US 25’s roadway characteristics

i ntersection adt
Intersection 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
crash locations
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
paper reports
Paper Reports
  • Submitted manually
  • GPS from Magellan, Google® Maps, 911 system
  • County, Route and Milepoint (CRMP) using reference system
ecrash kyops
eCrash KYOPS
  • MapIt
  • Added October 1st 2007
  • CRMP data linked to GPS
  • Between/Intersect streets
  • Searchable
  • RT Unique:

“034-US-0068 -000”

Synergy between spatial data and analysis
  • Imagine you are a national retailer
  • You need warehouses to supply your outlets
  • You do not wish the warehouses to be more than 1000 km from any outlet
