Idaho Transportation Department Karen A. Strauss, P.E. Pavement Management Engineer

Slide 2

What is Asset Management? ITDs previous pavement & maintenance management systems ITDs goals for the new asset management system How TAMS meets those goals

Slide 3

Definition: The practice of managing the whole life cycle (design, construction, commissioning, operating, maintaining, repairing, modifying, replacing and decommissioning/disposal) of physical and infrastructure assets.

Slide 4

TAMS includes: Pavement Management System Maintenance Management System Future Additions: Fleet Management Network Manager

Slide 5

A planning tool that models Pavement surface deterioration: Cracking Roughness Rutting Worst-First and Best-First Philosophy Worst-First: Fix the worst roads first Best-First: Preserve the most cost effective roads first

Slide 6

The question: How deficient (bad) are my roads? Recommends fixing the worst first, even if the worst road has little traffic and low speed

Slide 7

The question should be: What is the maximum benefit I can get from our money in the next 5 years? Concentrates on preserving the best of our impact roads first, considering: Speed Volume Expectation

Slide 8

Complex Centrally operated, no statewide access Worst-First No connection to maintenance activities

Slide 9

Labor-intensive Data stored in several different places Difficult to replicate consistent model results

Slide 10

Goals for TAMS Our new system needed: A relationship between pavement and maintenance Data available to everyone Repeatable, reliable analysis results Maximization of cost-to- benefit ratio Fast analysis of alternatives Network, District, & Project level functionality

Slide 11

Slide 12

The new TAMS system has: Best-first philosophy Asset Management Database Pavement Performance Analysis Connection to a Maintenance Management System Graphing, Reporting, and GIS Maps

Slide 13

We now house data accessible to all statewide TAMS users: Construction history Traffic and Safety Boring Log and Skid Data Visual Survey Data Profiler Van Data Signs and Supports Etc

Slide 14

The new system can answer commonly asked questions such as: If $20 million is added to my budget, how much better will the pavement deficiency be? How much should we spend to get to a deficiency of 15%? How much should be spent in each program category?

Slide 15

Pavement data can be graphed Reports automatically generated New reports can be user designed TAMS is linked to GIS

Slide 16

ITDs new asset management system (TAMS): Best-First philosophy Accessible data Robust analysis and mapping features Reliable and optimized planning for keeping our roads safe and in good condition
