What is a Pavement Management System and Why Should you Care?

• Software system that stores information on Roadway Surface Conditions, Maintenance History and Plans for Rehabilitation.

• It provides public agencies tools for evaluating roadways and planning maintenance of pavement over time and space.

What is a Pavement Management System and Why Should you Care?

• Nobody likes pot holes • They damage our cars • Road hazard for

bicyclists and pedestrians

• Not really good enough to fish in…

What is a Pavement Management System and Why Should you Care?

Traffic on our

roads increasing

Alternative transportation (Biking) more

important

Roads maintenance

Increasing

Costs increase and budgets

getting squeezed

• In California, the statewide average pavement condition has decreased to "at risk" status and is projected to worsen by 2024 if funding remains the same (Yap: 2014).

Some History on StreetSaver®

• StreetSaver® developed by MTC (Metropolitan Transportation Commission - Transportation planning, coordinating, and financing agency for the nine Bay Area Counties).

• A 1982 Study: jurisdictions not spending enough to adequately maintain roadways, creating massive deferred maintenance costs ($300-500 Million)

Some History on StreetSaver®

• Study results spurred development of the components of a Pavement Management System: • Pavement Condition Index (PCI) for road

evaluation - scale between 0 (failed) to 100 (new) • Effective treatments for distressed pavement • Pavement Management Software for tracking

sections.

Some History on StreetSaver®

Good Road Condition = Lower Maintenance Costs Going Forward

• StreetSaver® goal for organizations:

• Effectively plan and prioritize road rehabilitation • Bring pavement to optimal condition so it is more

cost effective to maintain going forward

Some History on StreetSaver®

1987 - MTC Pavement

Management System (PMS) First

Released

One of the first such software

programs implemented in

the United States.

MTC PMS renamed

StreetSaver® in 2003.

Eventually incorporated a GIS

module (within last 10 years).

Currently used in over 400 agencies

worldwide

Why is GIS Important for Pavement Management?

• Can easily visualize pavement

conditions and maintenance plans in a spatial context with: • Maintenance and Council

Districts • Adjacent Capital Projects

With GIS…

Why is GIS Important for Pavement Management?

• Easier to determine if there are streets or sections of streets missing from you database.

• Easier to identify errors in the segmentation (overlap, gaps)

With GIS…

Why is GIS Important for Pavement Management?

• Maps are effective

communication tools • Maps easily convey

priorities, problem areas, plans for the future on map

With GIS…

GIS Integration with StreetSaver®

• Process of matching pavement sections to GIS segments using StreetSaver Section Link module.

• Recent client implementations: • City of Grand Terrace • City of Wildomar • City of Eastvale • City of Bell • City of St Helena • City of Elk Grove • City of Rancho Cordova

Generally smaller, younger cities with less than 500 miles of roadway.

GIS Integration with StreetSaver®

Step 1 Prep Centerline File (Counties, COG, or local sources) and reference layers for use in map (e.g. schools, parks, city boundary, district boundaries, etc.). If you don't have centerline data StreetSaver will use TIGER data provided by the US Census Bureau*

Consider recalculating segment lengths for Cul-de-sacs

Step 2 Fill out StreetSaver GIS Order Form identifying centerline fields and layer settings for reference layers and email to MTC

Step 3 Upload shapefiles to FTP site (no geodatabase support currently).

Step 4 Log into StreetSaver and open Section Link module. View results of “auto link” to GIS street file.

Step 4: Auto linking Auto linking is automated process where StreetSaver attempts to match pavement sections to GIS segments using cross street names.

Step 5 Begin by matching partial links or unlinked sections -where StreetSaver could not fully match pavement section to GIS segment(s). Typically resulting from complexities in street network (e.g. self intersections) or errors/ inconsistencies in the pavement sections, GIS segments, or both.

Step 6 Review and verify Full Links established by auto linking Can be very time consuming for larger cities but essential because you can have Full Links established regardless of the reported pavement section length

GIS Integration with StreetSaver®

845 feet

6432 feet Full Link from Auto Link process

Difference of 5587 feet!

Step 7 Run reports and visualize your pavement conditions. Export GIS Shapefiles for mapping outside of StreetSaver.

Lessons Learned

• Start with cleanest Centerline data possible to minimize need for GIS update half way through.

• Online aspect of StreetSaver very helpful but can make GIS Update process a little tedious (download, edit, upload, repeat as necessary).

• Access to recorded development plans helps if you need to find out the official names of streets
