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

4
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 Citys enterprise
  GIS.

5
The Basic Problem

• StreetSaver is natively non-spatial
• Street segment definitions never match up between
  StreetSaver and a Citys native GIS
• There is no joining field between the two systems

6
The Solution Linear Referencing
7
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

8
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

10
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
