introduction
Introduction
  • Transportation Subcommittee was reinstated October 2010
  • Work Plan on Intermodal was approved by FGDC December 2011

Members include:

  • Mark Bradford, U.S. DOT
  • Raquel Hunt, U.S. DOT
  • Dick Vraga, USGS
  • Lynda Liptrap, Census
intermodal business plan
Intermodal Business Plan
  • Identify and standardize an intermodal facility database that can serve as a geographic foundation for all organizations dealing with modes of transportation.
    • This includes passenger and non-passenger activities.
  • The goal is to design the database in a way that will allow it to be adaptable
intermodal survey
Intermodal Survey
  • Identify the technical requirements for a spatial database
  • Identify the multiple business operations
  • Defined to accommodate the multiple users and not to be built to a specific set of business needs.
current intermodal database
Current Intermodal Database
  • Used the current US DOT Intermodal Database as a “starting point” to help define the technical requirements for a new intermodal database.
  • The existing database was designed to support the Commodity Flow Survey
  • The survey listed the Intermodal database definitions and data dictionaries for agreement or provide the modifications
timeline of action items
Timeline of Action Items
  • Presented the Work Plan to FGDC June 2012
  • Presented the Work Plan at ESRI UC July 2012
  • Survey sent out Sept 2012
  • Final Result return in Dec 2012
  • Tally results Jan/Feb 2013
  • Present results to FGDC April 2013
survey objectives
Survey Objectives
  • To assess its existing data resources and lay the groundwork for future efforts
  • Explore an intermodal framework that can be used by both the public and private sectors
  • Determine the commonalities of the data by the user community
methodology
Methodology
  • The survey was not intended to be a scientific survey
  • It was designed to lay the foundation for future investigation, data development, and interagency coordination.
  • Each TSC member was assigned a government agency and/or discipline to survey.
survey objectives1
Survey Objectives
  • General
    • Determining the type of user and their need for Intermodal
  • Specific
    • Changes to the existing database
    • Spatial Accuracy
    • Connections
    • Mandatory Attributes
  • Next Steps
    • Other Sources of Intermodal data
    • Other users of Intermodal data
  • Current Intermodal Database
    • Review of every attribute to determine: Required, Desired, or Needed
results general
Results - General
  • GIS users
  • Have need for Intermodal database
    • Use in routing
    • Passenger information valuable
  • Have regulations that apply to freight or passenger movement
results specific
Results - Specific
  • Agree with definitions used in Intermodal database
  • Represented as a point
    • 1:24,000 scale
  • Model with Multiple modes
  • Other useful attributes – weight, percentage of freight activity, average transfer time, number of passengers
  • Other identified issues
    • Support current models
    • One data source
    • Used for risk reduction/planning and policy
results next steps
Results – Next Steps
  • Contact other users of intermodal data (VOLPE, Local Agencies…)
  • Other sources of data – Official Railway Guide, Amtrak, Federal Lands, FHWA’s Freight Analysis Framework
  • Other useful information – AADT, feature level metadata, maintain multiple database identifiers for external systems
conclusion
Conclusion
  • Standardization of terminology
  • A single, expandable database; configurable depending on users’ needs
  • Facilities and mode networks
  • Because of resource shortages cannot pursue enhancement of the current intermodal data
next steps
Next Steps
  • Support TFTN efforts
  • Support mode specific data efforts in the NSDI
  • Promote/expand DOTs participation in data.gov to Geo.Data.gov
    • Publishing and hosting transportation specific WFS
