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
