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

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

Collected inventory

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

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

Ce 525

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”

Crash data plotted by gps and crmp within proximity to the kennedy interchange corridors

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

Ce 525

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

Synergy between spatial data and analysis

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
