Overview


Factors That Influence STIP Development


North Dakota STIP Development Cycle


Expectations and Limitations of our Asset
Management Tools


The Future

External Factors

Geographical:


Short Construction Season (Approximately 120 Days)


Behavior of expansive soils during spring thaw and
load restrictions.

External Factors

Project Delivery:


Preliminary Project Concepts to Delivery of Bid
Documents 18 to 12 months.


Many projects are not controversial from an
environmental standpoint.

Data Collection


Ride, rut, and distress data are collected in Summer
and Fall.


The collected data is analyzed in the winter and early
spring.

Example Pavement Management
Analysis


Summary


The projected average network IRI resulting from the 2011
-
2014 Final STIP is comparable to the
dTIMS optimized analysis projection.


Average Network IRI is projected to improve slightly from the current condition of 88 (Good) to 86
(Good) at the end of year 2014.





The projected percent miles meeting guidelines (Excel/Good) resulting from the 2011
-
2014
Final STIP is slightly less than the dTIMS optimized analysis.


Miles meeting guidelines is projected to remain steady at the current level of 77% between now and the
end of year 2014. (The current network goal is 85%.)





The projected Vehicle Miles Traveled (VMT) meeting guidelines resulting from the 2011
-
2014
Draft STIP is on average about 6 percentage points lower than the dTIMS optimized analysis
results.


VMT meeting guidelines is projected to remain steady at the current level of 85% between now and the
end of year 2014.





A comparison of the dTIMS optimized project recommendations to the projects in the 2011
-
2014 Final STIP indicates the following approximate correlation by year:


2011

66%



2013

62%


2012

78%



2014

54%

Expectations and Limitations


Our asset management systems will not be “black box”
systems.


Our asset management systems will not prescribe
projects, but rather recommend projects.


The better we can make our recommendations, the
more seriously people will take them.

The Future


Further Development of Asset Management Business
Practices


Cross Asset Tradeoff Analysis


Bridges


Maintenance

The Future


Continual Improvement of our Pavement and Bridge
Management Systems


Development of a Maintenance Management System


Investigation of future assets for Asset Management
Development.
