Dynamic Visualizations Created with D3

Check out the latest iteration of the data visualizations developed by students in the course – using D3. These visualizations are pulling data directly from the sensors in the bike counter and the weather sensors we set up during the class.

Mapbox Intro and Work Session

Lyzi Diamond from Mapbox will stick around after our lecture period on May 20th and conduct a hands-on work session in Condon Hall 206 (same room as lecture) from 11:00 – 12:30. Please consider bringing your laptop with Mapbox Studio installed. She will be bringing some transportation project samples. Mapbox can be downloaded for free under the Mapbox Education program.


Global Smart Cities Hackathon
Technology Association of Oregon
Saturday, May 16, 2015 from 9:00 AM to 5:00 PM (PDT)
Beaverton, OR

Portland is participating in the Global Smart Cities Challenge, and on May 16th we invite you to join us for a Global Smart Cities Hackathon leveraging Intelligent Transit and Air Quality data. The Hackathon will bring together students, developers, and designers from across the Portland area to build apps and visualizations using the data collected from traffic and air quality sensors along SE Powell Boulevard.


This opportunity/invitation is from Josh Roll, Transportation Planner at Lane Council of Governments, one of our upcoming guest speakers  – Ken


Do you ride a bike?
Do you know someone who rides a bike?
Or do you know someone that knows someone that saw a Kevin Bacon movie with a bike in it?
If so this email applies to you!
We need members of our community to download and use the ORCycle smart phone app.
This app lets you log your bicycle route and pinpoint safety problems along your route.  Additional functionality lets you plot bicycle safety concerns anywhere in the region!  All you have to do is download the app and use it!
These data will used in the upcoming CLMPO/Lane County Safety and Security plan, bicycle route choice modeling, and general system operations.  
Starting this week, we are initiating as big of public outreach push as we can, getting the word out to the public and our partners through social media, official notification, work of mouth, and this email blast!  This email is only helpful if you do one of two things:
  • Download and use the ORCycle app
  • Tell a friend about ORCycle app and watch them download the app and use it J
Other things you can do to help, become a twitter follower, like us on Facebook, share this email or our social media links with your friends, oh and download and use the app!
In case you needed a motive other than civic duty , users that log trips will be entered into a drawing for free stuff from local bike shops and retailers, though I suspect duty to one’s community will be sufficient.
Thank you for your time and have fun our their today in the sunshine!

Many of you have expressed interest in experimenting with additional data – for visualization in Tableau.

Here is additional bike count data from LCOG.  Consider using the Hourly Data.  Next think about how you could transform the data to be true DateTime format, suitable for plotting on a timeline.

Here is a month of data from the HiPE FIT Facility in/on Onyx Bridge.  FIT Data 11_25-12_5_master. Here is a link to their visualization experiment .

We’ve also tracked down bike counter data from Seattle (Freemont Bridge).  This counter is very similar to UO’s bike counter — continuous, single location, etc.

Enjoy – Ken




On Security of Power System State Estimation

KEC 1003
Monday, May 4, 2015 – 4:00pm to 4:50pm

A defining feature of a smart grid is its ability to incorporate advanced data analytics for real time monitoring and control. However, heavy reliance on networking for data collection inevitably exposes a grid to threats of cyber attacks. In this talk, we consider data falsification attacks on power system state estimation, where an attacker alters certain sensor data to mislead the control center with an incorrect state estimate.

We first present a necessary and sufficient condition under which an undetectable attack exists. We present a data-driven undetectable attack that does not require any system parameter information; by exploiting subspace estimation technique, we show that partial sensor observations can provide sufficient information for designing undetectable attacks. Then, in order to protect a grid from potential attacks, we develop countermeasures based on sensor data authentication. It is shown that if data from a set of sensors satisfying certain graph-covering property are protected, any attack can be detected.

Speaker Biography:
Jinsub Kim has been an assistant professor of the School of EECS at Oregon State University since 2014. He received his Ph.D. in Electrical and Computer Engineering from Cornell University in 2014. His research interest spans statistical signal processing, optimization, power systems, and security. In particular, he is currently working on developing robust state estimator for power system and potential mechanism of dynamic data falsification attack.

Data Visualization Presentation.  Miriah Meyer from the University of Utah will be speaking at the Computer and Information Science Colloquium on April 30, 2015 at 3:30 in 220 Deschutes.  This looks like a really good talk – from a major player in the data viz space. Ken

HOPES Conference is this week – April 9,10,11.  “Catalyst: 21st Century Systems” – here on our campus – in Lawrence Hall.  There are some great, Smart City flavored, talks on the agenda.  I’ve posted two below that I’m going to try to attend (dad duties permitting…) that involve Carlo Ratti – the Director of MIT’s Senseable Cities Lab. You’ve seen his work referenced in several of our readings and I’ve shown a few of their projects in lecture. Ken

Senseable Cities
with Carlo Ratti
Lawrence 115   10:30 am – 11:30 am

Transit and the City: Systems That Inspire
with Andrew Heumann, Jennifer Wieland, Chris Bell, Carlo Ratti, Rab Zako, and Philip Speranza
Lawrence 206     1:00 pm – 2:00 pm


Computer and Information Science (CIS) has an entrepreneurship-focused departmental colloquium this week. Embedded systems are right up the alley of Smart Cities – this looks like a good talk. Ken

Thursday April 9th from 3:30pm to 5:00pm in 220 Deschutes Hall.

Abstract of Talk:
This talk will introduce basic embedded systems and bridge general-purpose computing software to the application of programming small simple microprocessors, which can then directly interact with any example of circuitry. Basic prototyping methods and tools will be discussed including specific examples and tools that will be of immediate use to anyone with an idea for an embedded system. Finally, the business startup aspect will be discussed including team building and funding with an emphasis on crowdfunding via platforms such as Kickstarter.

Kevin King is a self taught electrical engineer. He invented a radio control system for photographic lighting in 2007 and learned electronics as a necessity to bring the product to market. In February 2015 he founded Plum Geek LLC as a new endeavor aimed at open source hardware and robotics. The intention is to build a sustainable business based on developing open hardware that can be used for pure entertainment as well as education. The Ringo robot is the first product offered by Plum Geek, and recently raised over $85,000 on Kickstarter toward an initial goal of $12,000.
