2 Options for Data Collection:

Photo Log Van


KYTC Photo Log

KYTC Photo Log

  • KYTC Asset Collection Vehicle

  • Right of Way Cameras

    • 3 cameras; One facing forward, right and left

  • Global Positioning System

    • Includes Differential and Inertial Measurement Systems

    • Sub-meter accuracy at highway speeds

    • Inertial Measurement System retains correct position during GPS Dropouts

  • Distance Measure Instrument

  • Roughness Measurement

    • Dynatest Mark IV RSP

  • Rutting Measurement

    • INO Laser Rut Measurement System

    • 1280 Transverse points


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

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


H igh c rash i ntersections
High Crash Intersections

  • Intersection list

  • Intersection ADT

  • Assign intersection crashes

  • Calculate intersection crash rates

  • Identify high crash intersections

KY 29

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

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”

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

Travel time study
Travel Time Study “Kennedy Interchange Corridors” (2005 to 2009

  • 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

Location allocation outputs
Location-Allocation Outputs Coverage

  • 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
Synergy between spatial data and analysis Coverage

  • 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
