LBZlogo-M

As an optional add-on to LinearBench® Explore, LinearBench® Analyze (LBZ) is the industry’s first, comprehensive LRS data analysis software.  Powered by Gistic’s patent-pending Grid-based LRS Segment Join technology, Analyze makes complicated analysis tasks accessible to all users with its intuitive UI design. Analyze contains a collection of data analysis and QC functions designed specifically for LRS asset data processing to meet the needs of transportation professionals.

Key Features

    — LRS Data Analysis

Overlay function results displayed on LBZ tab – 4-layer, left-join overlay

  • Overlay – “joins” two or more LRS asset layers to generate a logically-segmented set of LRS segments.  May be used to generate report with combinations of crash, speed limit and pavement condition data to analyze their effect on accident rates.  It supports the outer join types in addition to the inner join.

Summarize function results displayed on SLD tab – Crash over AADT layer

  • Summarize – calculates basic statistics of selected asset attributes either by equal-length route segments or in relation to a reference layer.  May be used to calculate the average crash severity and average number of vehicles involved within each ¼ mile section on given routes.
  • Gap – identifies locations in a layer where LRS data does not exist.  May be used to identify locations where ADT data has not been collected.
  • Overlap – identifies locations in a layer where LRS data overlaps.  May be used to identify locations where speed limit data overlaps.

 

    — LRS QC

Route switchback error displayed on LBZ tab

  • LRS Network – detects 14 different warning or error conditions, such as:
    • Completeness – missing or duplicate routes
    • Geometry – routes with switchbacks
    • Topology – route gaps
    • Measure – difference in length between GIS and Route measure
  • LRS Data (event/asset layer) – applies 3 topology rules:
    • Domain – identifies route measures beyond the range of their corresponding routes
    • Gap – identifies places along the route where no data records exist
    • Overlap – identifies places along the route where data records overlap
  • Supports creation of user-defined QC rules

 

    — Route-Reference Table Generation
  • Generates route-reference tables using a high-performance algorithm that is data model-independent
  • Supports the “Reference Point with Offset” LRM, key to referencing assets on most local roads
  • Features flexible route-reference table generation, with scope and topological options
