Understanding TDM throughout the greater Portland region

Steer is working with Oregon Metro on Phase I of a regional TDM Inventory, to help the agency better understand existing TDM throughout the region. This phase of the project involves data collection and mapping activities to support the development of an ArcGIS Storymap of TDM programs and infrastructure throughout the region.

How we helped

In the initial stages of the project, Steer worked with Metro to refine a list of approximately 100 TDM strategies in four major categories: infrastructure, policy/plans, TDM programs and support, and new mobility. Each of these strategies were classified into related subcategories and modes to facilitate search and filter functions. Steer then devised a draft structure for the Access database and geodatabase, which outlined the type of information that would be collected and how it would be formatted, stored and transferred.

Data collection and mapping activities overlapped and were able to inform one another. Steer surveyed data sources and website associated with more than 100 agencies, organizations, and municipalities to collect data on TDM activities. Information was imported into a master Access database. For each project, Steer prepared an associated shapefile, either from existing spatial data or from geocoding. The final dataset was joined to each respective shapefile as an attribute table.

Accomplishments

Steer completed the scope of work by providing the final databases, metadata, and recommendations for ongoing maintenance and updates. Metro will use these outputs to build the final ArcStorymap, which will be an open access resource available to local agencies, organizations and the public to better understand how TDM programs are deployed in the Metro Portland area.
