Abstract
Pima County, AZ, Linear Referencing System/Dynamic Segmentation
Track: Transportation
Author
The street network is a critical data layer for DOT - supporting multiple departments and agencies - enabling key business processes such as pavement management, emergency response, etc, etc. Because the street network supports a wide array of GIS consumers, the data must be capable of supporting varying workflows and applications, without compromising data integrity or maintenance efficiency. LRS/DynSeg allows multiple attributes to reference a single route while preserving linear network geometry. For this reason, Pima County AZ is implementing LRS/DynSeg to preserve non-typical core street attribution while reducing segmentation.
This presentation will provide an overview of core linear referencing and dynamic segmentation concepts, present the business case for adoption by the county, as well as lessons learned and the road ahead. Topics will include an in-depth discussion of the LRS data architecture, data collection/creation procedures, tools and methodologies used to implement Pima Counties LRS/DynSeg.
