What is streetsaver l.jpg

What is StreetSaver?

“StreetSaver® v.9 is a tool helping cities and counties make informed, and timely, decisions about their pavements - preventing problems through judicious maintenance, and diagnosing and repairing problems that exist in a cost-effective manner.”

  • Inventories pavement sections

  • Evaluates “pavement condition” (PCI)

  • Recommends pavement treatment projects that optimize overall PCI within user-defined budget

www.fargeo.com

What is StreetSaver? cont…

  • Desktop application, accessed over the web with remote desktop (more about that later).

  • Includes a built-in GIS module designed to operate in isolation from a City’s enterprise GIS.

The basic problem l.jpg

The Basic Problem

  • StreetSaver is natively non-spatial

  • Street segment definitions never match up between StreetSaver and a City’s native GIS

  • There is no joining field between the two systems

The Solution:

Linear Referencing

Linear Referencing

Geographic Referencing

Linear Referencing

  • Datum: NAD83 (for example)

  • Datum: Linear Features, Road Name & Measurement Attributes

  • Geocoding: Creating GIS features from tabular data with coordinates

  • Dynamic Segmentation: Creating GIS features from tabular data with road names and measures

Importance of LRS/Dynamic Segmentation

  • Minimizes GIS data management -

    • no need to duplicate and re-segment street geometry

  • Allows ‘event’ measure data to reside in the appropriate system - PMS

  • Use the LRS to Integrate data from other systems –

    • CMMS (streets, signs, sidewalks), ADT, speed limits, bike routes, accidents, …anything that can be referenced against a street

Geomedia Integration Workflow

1 of 2

  • Add Route identifier to street centerlines

    • Generally based on street name

    • Use StreetID from StreetSaver at Cities, use Road Number at Counties

  • LRS-enable street centerline network using Transportation Manager

    • East to West, South to North – Standards based

    • Manually calibrate tricky segments (loops, dual carriage-ways) using Interactive LRS Calibration

Geomedia integration workflow 2 of 2 l.jpg

Geomedia Integration Workflow 2 of 2

  • Develop Pavement Event Data

    • Create point features for each beginning and end locations of each section where possible:

      • Intersections

      • Addresses (using geocoding)

      • Offsets from known locations, etc…

      • Get creative

    • Convert “geographic” points to “LRS measures” using Transportation Manager “LRS Conversion Tool”

    • Generate measure values manually using a geomedia ‘inbox’
