Engage in marketing, training, and outreach of Archived Data Management Systems (ADMS)
Experience from six Archived Data Management Systems case studies.
- Inform users about the quality of the data they are using. Agencies use different methods for data quality assurance, and they need to share this information with users, so that the users can make any necessary adjustments in their analysis.
- Caltrans PeMS assesses data as they are received and determines if any data are suspect or missing. Missing or suspect data are automatically replaced with a value imputed from the adjacent values.
- The Detroit MITS system automatically checks data quality based on diagnostics that evaluate how well each loop is operating. Data that are suspect for a given location are subsequently flagged.
- Washington TRAC does not automatically generate data to replace data that is missing or considered bad or suspect. Users of the data must decide whether to accept questionable data and must identify methods for dealing with bad or suspect data.
- Provide training classes for system users so that they understand the data/applications they are using.
- Washington State TRAC developed a formal training class for the archive and analysis software. This class is given on demand to WSDOT staff and other invited public agency personnel. A website was created to provide training support.
- For PeMS, training is provided to Caltrans staff and planning staff from the San Diego Association of Governments (SANDAG).
- Market the potential uses of archived ITS data to the transportation community.
- Members of the University of Washington staff speak at national meetings about how the archive (Washington State TRAC) is used and why it is valuable. WSDOT staff is also responsible for making other WSDOT staff aware of the archive and analysis software’s availability and uses.
- Program directors from UC Berkeley (the host of PeMS) highlight the value of Caltrans PeMS to potential users by regularly participating in national conferences and committees.
