1. Highway Performance Monitoring System Implementation Using FME
Tom Roff, FHWA
GIS/Database Applications Project Manager

Applications Developer

2. Background How a road is funded. Highway Trust Fund
Apportionment Formulas
Length
Lane-Length
Vehicle-Miles Traveled

3. Highway Performance Monitoring System
Annual Submittal
65 attributes
Inventory
Condition – Pavement
Performance – Traffic and Congestion
Other primarily for safety analysis

4. Previous version was a flat table of attributes
The Problem
Previous version was a flat table of attributes
Only reliable for State level statistics
Data not referenced to a location
Tremendous burden goes to transforming data from a State System to a Federal Reporting System
Realization that we must go spatial!

5. Failed Attempts
TIGER Digitized DLG Commercial Datasets – GDT, NAVTEC And something called the NHPN… (Don’t worry about what this is because it does not work)

6. …which brings us to Massachusetts
The 2003 Massachusetts HPMS submittal looked something like this after we DynSeged it to NHPN

7. Massachusetts
After Contacting MassEOT and using their network…

8. Massachusetts
Something that was also sent from MassEOT

9. STOP TRYING TO FORCE FIT STATE DOT DATA INTO A FEDERAL NETWORK!!!
Wake up
STOP TRYING TO FORCE FIT STATE DOT DATA INTO A FEDERAL NETWORK!!!

10. Adoption of the State DOT Networks
Most States have a more complete Networks
Some have complete coverage of all public roads
The accuracy of most states is 1:24,000.
A handful are accuracy to 1:5,000
Adoption of state networks would eliminate maintenance and associated costs from FHWA
The State DOTs are maintaining their networks for their own business needs
Often, the state networks are integrated with the states traffic, bridge, and pavement management system. Some are integrated with rail networks

11. Linear Referencing
The advantage to using a linear reference system is that the display of features is not dependant on the spatial accuracy of a geographic network. An event will always be displayed on the road.

12. Data Model

13. State Networks
Transportation for the Nation – TFTN
Initiative to establish one road network for the entire nation
It should reside at the USDOT
Emphasis to use HPMS as the starting point for the TFTN Initiative

14. FME Requirements Requirements of FME
ESRI Shape, ESRI Personal Geodatabase, Geomedia Database Import and Export
Unit of Measure Conversion
Dissolve Routes
Linear Reference Validation

15. Nom2Sp

16. Routes2Shape

17. To Shape

18. What we would like to see from FME
Linear Reference Functions
SQL Writer to support Measures
Dissolve Function
Measure Unit Converter
Measure and Part Sequence
Better load performance to SQL Server
