KYTC Photo Log
Panoramic View
Sign Measurement
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
Collected Inventory
Manual Collection:• Area Development Districts contracted to collect data
• Data stored in shapefile and geodatabase
• Merged with Photo Log database
KYTC Manual Collection
Crash DataTransportation
High Crash Intersections Intersection list Intersection ADT Assign intersection crashes Calculate intersection crash rates Identify high crash intersections
KY 29
KY 29US 68
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
Intersection of US 25 and US 27This record would contain US 25’s roadway characteristics
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
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
Submitted manually GPS from Magellan,
Google® Maps, 911 system
County, Route and Milepoint (CRMP) using reference system

Crash Data Potted by GPS
Crash Data plotted by GPS Showing County Check
Kennedy Bridge Study
Crash data plotted by GPS and CRMP within proximity to the “Kennedy Interchange corridors”
Crashes occurring outside the buffer zones were selected due to their location description or using engineering judgment
EPDO Density Plots for the “Kennedy Interchange Corridors” (2005 to 2009)
EPDO Density Plots for the I-64 and I-65 section of the “Kennedy Interchange Corridors” (2005 to 2009)
Travel DataTransportation, Planning, …
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

Potential CORS Stations In and Near Kentucky and Their Coverage
Location-Allocation Outputs The best sites The optimal allocation of demand locations to
those sites Lots of statistical and summary information about
that particular allocation

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
