For the last two years, I’ve mapped the flows of the Nice Ride bikes. I’ve always been slightly dissatisfied with the results, since bikes were obviously shown taking routes that any sane Nice Rider would never take (Hennepin Avenue between Lake and the bottleneck, for example). Try as I might, I could never get ArcGIS to prioritize trails, lanes and bike boulevards sufficiently.
Enter the good people at Cyclopath. Cyclopath is something like a bike route wiki, in that it is constantly updating it’s database of bike routes using ratings from users. So every street in their database has a rating from bad to awesome (actually 0 to 4). And this database includes the whole metro and beyond. Best of all, they were willing to share it!
The latest version of ArcGIS has a new “restriction preference” setting, meaning there are six levels of preference for a link from “Highly Avoid” to “Highly Prefer”. So I combined cyclopath’s street ratings with these preference settings and got a new and better route analyzer. Here are the results:
As a reminder, here is what the old version looked like:
A few changes of note:
- Hennepin is obviously not so popular anymore, save in downtown where there are more Nice Ride Stations.
- The Cedar Lake Trail got a little more popular, perhaps 500 trips in some locations, since it was a Highly Preferred route.
- West River Parkway south of the Washington Avenue bridge got a lot less popular (although crossings at Franklin stayed nearly the same).
- There is generally just a lot less jigging and jogging on small streets as trips tend to condense onto major routes (see the major difference on Summit Avenue in Saint Paul).
Here is a version with a base street map for orientation:

Over at streets.mn this week, I make the case that after Park and Portland, we need to start planning a network of cycletracks more systematically in Minneapolis and Saint Paul. Read it now.
Nice Ride released their 2011 ridership data in January, and I’ve been itching to map it ever since. Flows (don’t call them fluxes) are a particularly interesting way to visualize the ridership over different route segments.
I used ArcGIS with Network Analyst on a heavily modified Open Streets Map metro shapefile to generate routes between the start and ending station of each Nice Ride rental. The Open Streets map file allowed me to include off-street trails (very important in Minneapolis), which weren’t included in my previous attempts. I set Network Analyst to prefer off-street trails, bike lanes and regular roads (in that order).
Other than being pretty, you can draw a few interesting conclusions from the flows:
- The most traversed segment, with over 16,000 trips, was the off-street trail through the Hennepin-Lyndale bottleneck (although likely some of this traffic went to the Cedar Lake Trail in real life). In my opinion, this is a horrible segment for bikes and peds and if we’re trying to attract visitors back to Minneapolis, we should do something about it.
- Other heavily-traveled areas are the Mississippi River bridges, downtown streets, and Uptown.
- Men and women take similar routes. I mapped both, but the flows looked very similar.
- People are using Nice Ride even in the middle of the night. They are sticking even more closely to the southwest-to-northeast spine common during the day.
- 30-day and Annual subscribers are getting into the neighborhoods more than casual subscribers (single day), pointing to the obvious conclusion that they are full-time residents who are using Nice Ride to go to and from homes more often.
- Since Saint Paul only had a partial year of service, it’s hard to draw many conclusions yet.
What else do you see?

Policy Link, Take Action MN and Isaiah have released a health impact assessment for the coming Central Corridor light rail line. In my opinion, this seems more like an economic impact assessment, but the argument can be made that economics drives health.
My summary of the findings:
- Jobs in the corridor will increase, particularly retail and office.
- Population and housing will increase.
- Jobs with skills matching those of current residents will be low-paying. Higher wage jobs will increase too, but won’t be available to many current residents.
- Low-skill, higher paying jobs (in manufacturing, for example) will be forced out.
- Commercial rents may rise, forcing out small/independently-owned businesses.
- Additional density could be in the form of housing affordable to current residents, but not without careful planning.
- More people walking and biking is good, but existing pedestrian conditions are “hazardous”. The city (St Paul) has some plans to address this.
I question comments like this: “The reduction in allowable densities east of Lexington Parkway along University Avenue, however, will help to reduce the pressure on existing small and minority-owned businesses in the east submarket.” I understand the issue of redevelopment pushing out existing businesses (they might not be able to afford rent in new mixed-use buildings), but isn’t density good for any business (save auto dealers)?
The report also has five policy recommendations for creating a healthier environment moving forward. Here’s my (very abbreviated) summary:
- A modified inclusionary zoning ordinance.
- Codify affordable housing goals in the Traditional Neighborhood zoning category.
- Give a density/height bonus or reduced parking requirements to developments with affordable housing component.
- Allow temporary parking lots on vacant lots during construction. In theory, this would help businesses during LRT construction.
- A local hiring action program giving preference for construction jobs.
What this seems to leave out is any recommendation on how to incorporate small businesses into new development. Is it impossible/very difficult to program space in new mixed use developments for small/independent businesses? Do developers only want chains? Are rents simply too high? Has any city every adopted an affordable commercial space policy to set aside a certain portion of commercial space for smaller businesses? Smarter folks than I surely must have thought about this.
St. Paul has a nice video introducing their electric vehicle charging infrastructure. According to a presentation I saw at MNAPA, the City hopes to have 150 public stations available by 2015. They also estimated that the cost for installation was anywhere between $850 in parking ramps to $6,000 in on-street spaces.
A big thanks to everyone who attended the ULI Minnesota Kids in the City Program on March 10th. The panel was excellent and the discussion was great. Below is the intro presentation that was given during the event.
This week, the US Census released 2010 data for Minnesota. I haven’t had much time to dig into the data, but I did check a few things. First, I checked the health (in terms of population) of Minneapolis and Saint Paul, our core cities. We seem to have bucked the trend, being seen in many midwestern core cities, of population decline. Minneapolis is down 40 people since 2000 and Saint Paul lost 2,083 (-0.7%).
Although our core city population growth seems to be flat or declining, Minneapolis and Saint Paul also seem to be experiencing the “downtown renaissance” being seen in other parts of the country.
Using Census tracts that approximate the areas of each downtown (Minneapolis: south of Plymouth Avenue, inside the freeway belt, south of the river; Saint Paul: inside the freeway belt, north of the river) I compared population from 2000 to 2010. The results are shown in the table below. Both downtowns seem to be healthy and growing.
