How It’s Made: A PlanScore Predictive Model for Partisan Elections

I’ve been writing at Medium.com for the past year. Read this full original post there.

With the mid-term elections in full swing and campaigns focused on the districts we have, PlanScore has had a quiet few months. Earlier in the year Pennsylvania redrew its U.S. House districts with a rush of competing plans submitted by participants from all over the state’s political landscape. PlanScore’s Nicholas Stephanopoulos reviewed them all using our models and described the process on the Election Law Blog. Last month, the Virginia General Assembly had until October 30 to pass a remedial map after a district court in Virginia struck down eleven House of Delegates districts on racial gerrymandering grounds. We scored those too, and Nick wrote about the process again.

After the 2018 mid-terms, we’ll be headed into a three-year Census and redistricting cycle redistricting cycle where all 50 states get new maps just like Pennsylvania and Virginia did in their special processes. In this post, I’ll describe how we make PlanScore’s prediction models to support that cycle and help ensure fair maps for every state.

Micromobility Data Policies: A Survey of City Needs

I’ve been writing at Medium.com for the past year. Read this full original post there.

In the past year, cities have been prompted to rapidly re-examine the management and regulation of transportation services due to the influx of micromobility. This recent movement has illuminated major opportunities to expand transportation options while highlighting several challenges for widespread adoption and support. In the context of data, the conversation has evolved quite differently from TNCs just a few years ago. Cities are creating detailed data requirements for operators and are successfully obtaining that information as an input for smarter future transportation plans.

We surveyed over a dozen emerging micromobility data sharing policies in places like Nashville, Chicago, Seattle, Portland, Santa Monica, Dallas, San Francisco, Austin, Denver, Pittsburgh, Houston, Durham, Salt Lake City, and Chattanooga. These policies represent a combination of exploratory pilot programs, post-pilot permits, and even one emergency rule. Based on our research, we see these core data sharing policy features:

Open Precinct Data

I’ve been writing at Medium.com for the past year. Read this full original post there.

Several weeks ago, I spent an extended weekend at the fifth (of five) Geometry in Redistricting conference. Apart from speaking and participating in a panel on law, tech, and gerrymandering, organizer Moon Duchin asked for my help organizing the conference hackathon. One theme I heard repeated throughout the event centered on the difficulty of finding reliable precinct geography and election results.

There’s an opportunity here for a new data project focused on connecting existing academic and independent efforts with durable, unique, permanent identifiers for nationwide voting precincts. Imagine if you could easily correlate detailed voting results from OpenElections.net (OE) or state boards of elections with mapped polygons and census geography over time. We already know how effective a GEOID-based approach can be thanks to data published by the U.S. Census, but precincts are a special challenge without a current champion.

Scoring Pennsylvania

I’ve been writing at Medium.com for the past year. Read this full original post there.

On February 13 we launched PlanScore.org into the whirlwind of Pennsylvania’s disputed congressional plan. Our mission is to help citizens evaluate new redistricting plans for partisan skew and to elevate the conversation on partisan gerrymandering with new historical data for state and U.S. congressional district plans. It’s been an exciting couple of weeks. What did we learn, and how are we doing at reaching our goals?

Every district plan is designed to do a job: apportioning voters into Congressional districts so they can elect members to the U.S. House, typically following traditional redistricting criteria like compactness, contiguity, and preservation of communities and incumbents. Since 2010, we’ve seen the emergence of detailed computer models that allow for the creation of unfair, skewed maps that still conform to traditional criteria.

Coming To A Street Near You: Help Remix Create a New Tool for Street Designers

I’ve been writing at Medium.com for the past year. Read this full original post there.

Vibrant cities rely on the seamless connectivity of people and ideas. Streets enable these connections: your city’s community members need good streets to access jobs, move safely and sustainably, and live well.

Here at Remix, we’re excited to pilot a new product to design city streets.

We’re designing it on top of the new data standard called SharedStreets, which is being developed by the National Association of City Transportation Officials (NACTO) and the Open Transport Partnership. We need your input to help us build the right thing! 🎉
