Connected Data Systems (CDS) Program

Vision – Showing how emerging data can transform surface transportation systems management Mission – The CDS Program seeks to develop scalable data management and delivery methods,

□ Exploiting the potential of high-volume multi-source data

from connected and automated vehicles, connected travelers with mobile devices & other sources,

□ To enhance current operational practices & transform

surface transportation system management

CDS Program Goals

  • The CDS Program will

□ provide transportation system operating agencies and

their partners

□ with tools and guidance that will allow them to

▪ collect and exchange data from connected vehicles and mobile devices ▪ extract value from those data ▪ share data with others

Research Data Exchange (RDE)

  • Promotes:
  • Sharing

Collecting & providing access to

  • Archived &

real-time connected vehicle & traveler data

  • www.its-rde.net

Data Environments in the RDE

  • 14 Current Data Environments:

□ CV data from Leesburg, Ann Arbor, Orlando, and Detroit □ Road Weather warnings from Detroit demo □ Multi-modal traffic and signal data from Pasadena, Seattle,

Portland, and San Diego

□ Probe data from Southeast Michigan testbed

  • 8 Data Environments Coming Soon - Dynamic Mobility

Applications

□ Multi-Modal Intelligent Signal Systems (MMITSS) □ Intelligent Network Flow Optimization (INFLO) □ Integrated Dynamic Transit Operation (IDTO)

  • 25+ New Data Sets to Be Added to RDE in 2016

New data sets are added to the RDE as they become available:

□ From other USDOT projects □ From outside submissions

Data Submission Process

  • Researchers invited to submit

data to add to RDE

□ Use “Contact Us” link under the

“About” pull-down menu.

  • USDOT reviews & assesses

potential data:

□ Value □ Quality

  • Data added to RDE when it

passes this review & criteria

Identifying and Adding Data to the RDE

KEY ASPECTS OF EACH PHASE: KEY ASPECTS OF EACH PHASE:

  • Engage data providers to identify data sources and

assess the data source’s content. Decide if data source(s) have research/application potential.

  • Explore the data by obtaining a sample, and assess the

sample for its research value. Decide if data sample will be

  • f sufficient value to continue capture effort.
  • Obtain complete data sets. Decide on structure for data.

Prepare the data for public posting or secure storage.

  • Post the data and release for public access.

Data Sharing Challenges

  • Ease of Use for the Data

□

Structure the data files for easy use – no mammoth files

□

Comprehensive documentation

  • Real-Time vs. Archived Data

□

Determine most useful method of providing data for access and use

  • Data Quality

□

Check data quality before, during, and after data collection.

□

Verify quality before transmitting for evaluation and sharing to the public

  • Timeliness

□

Get data quality checked, documented & available as soon as possible

Key Issues Considered to Post Data Key Issues Considered to Post Data

  • The government must have written rights to distribute or

allow others to use the data on RDE

  • The data must not contain sensitive information (e.g.,

personally Identifiable Information (PII))

  • The data must be documented
  • The data is in a common non-proprietary format
  • The data has been quality checked

Metadata Documents

  • Guidance for Metadata Documentation based on ASTM

2468-05 Standard

  • Required Fields:

□ Description of data collection procedures □ Time and location of collected data □ Contact information □ For each data element:

▪ Type (e.g., integer, float, character) ▪ Units ▪ Field length ▪ Max and min values, if applicable ▪ Definitions of codes, if applicable

How We Can Coordinate

  • Post FOT-NET files on the RDE as new data environments
  • Coordinate for RDE to “Federate” with FOT-NET files

□ Include links to FOT-NET files □ Include in search capabilities

  • USDOT to take advantage of FESTA guidance

□ FESTA guidance has been incorporated in design of Connected

Vehicle Pilot program deployment and evaluation

  • USDOT participation in updating FESTA guidance for data

collection

  • FOT-NET to review USDOT guidance
  • Coordinated planning for future workshops

How We Can Coordinate

  • U.S. BSM Emulator Simulator can simulate the generation of European Cooperative

Awareness Messages (CAM) to compare to U.S. Probe Data Messages, tied to a traffic simulation model (VISSIM or Paramics)
