Data availability - WSDOT, other agencies & private sector

Data helps drive decision making and measure the performance of transportation strategies. Agencies can source certain types of data from WSDOT, other agencies, and the private sector.

Strategy description

WSDOT has a range of data resources available for staff to use to support transportation systems operations. Data from other public agencies and the private section can support numerous planning and operations decisions and extend the usability of WSDOT’s traffic and operations data. 

Data availability at WSDOT 

Access WSDOT’s databases, including

Other agencies 

It is also possible to access data from agencies with roads and Intelligent Transportation Systems (ITS) that are adjacent or linked to WSDOT’s systems.

Private sector 

Typically, agencies can purchase private sector data from vendors such as Inrix or Blip. Data collection uses technologies such as license plate or Bluetooth readers, mobile phones, or in-vehicle GPS. Some systems are crowd sourced and are freely available to the public (for example, WAZE for Google Maps), but WSDOT has no control over the data content or accuracy. In some cases, WSDOT can purchase raw data directly from vendors.

What you need in order to implement

In order to source data from WSDOT or additional sources, you will need 

  • Sources of WSDOT data, including ITS and management systems
  • Sources of data external to WSDOT
  • Data integration into a database accessible by WSDOT staff
  • A framework for data set quality assurance and updating
  • Training materials and data dictionaries to support the staff’s effective use of the data
  • Internal contacts (stewards) for WSDOT database support and problem reporting
