Stick Diagrams
  • The first SLD was produced in 1968 to display
    inventory data
  • It was a collection of stick diagrams showing
    locations of events referenced to the mile point
    along the route
  • Some of the items displayed
  • Intersecting streets and grade separated
    interchanges
  • Streams, railroad crossing
  • Corporate boundaries
  • Manual process drawn on linen or mylar using ink
    and Leroy lettering

3
Automated SLD Sheet Creation
  • In 1995, NJDOT and its consultant, Michael Baker
    Jr., Inc., embarked on an effort to automate the
    production of the SLD sheets.
  • The client/server application was developed and
    deployed at NJDOT to enable customized SLD sheet
    creation.

4
System Expansion
  • As the popularity of the automated SLD grew,
    other management systems inquired about having
    their data displayed in the SLD
  • Pavement
  • Safety
  • Bridge
  • Many SLD data and external data have frequent
    update cycles

5
System Expansion
  • The public, MPOs, local governments and the
    engineering community routinely request data from
    the SLD database
  • Additional applications were developed to
    disseminate the data (both SLD and external data)
  • Video Log
  • PhotoBook
  • Web SLD

6
Platform Move
  • The SLD currently is the hub that publishes the
    majority of NJDOT data along the road network
  • NJDOT has been Data Rich but Information Poor
  • NJDOT needs to empower users to convert data into
    useful information
  • NJDOT needs to disseminate the SLD information to
    a broader audience via
  • Thin Client Applications
  • Web Dissemination (including Web Services)
  • Handheld Applications
  • Popular Data Formats
  • Dashboard Displays
  • Theme-based Query Builder
