Portal is the Portland-Vancouver transportation data archive with a recent expansion to Central Lane County. PORTAL archives multi-modal transportation-related data to preserve the data and provide a resource for local agencies and students. PORTAL's web site provides tools for analysis of traffic and transit data to support operations, planning and performance measures. Portal is supported by Metro and RTC, with previous support from NSF, FHWA and OTREC.

The Portland Observatory: Data Intensive Decision Making

The Portland Observatory is investigating the problem of Variety in Big Data. In particular, we focus on the issue of data intensive decision making and using Big Data technologies to improve the effectiveness of turning data into information and insight. insight useful to citizens and decision makers. The Observatory is building a testbed focused on transportation data. Our goals are safety, sustainability and effectiveness and our target uses are decision makers and citizens. The Portland Observatory is supported by the Intel ISTC-BD and a Maseeh Professorship.


S-Store is a collaboration with MIT and Brown through the Intel ISTC-Big Data. We are developing a stream processing system with transactional capabilities. The system will be demo'd at VLDB 2014 in September, 2014.
