WorkCycles Fr8 fits on the CTA’s bus-bike rack!

November 11, 2012 / / 12 Comments

If you ride a bike more than you use other transportation modes, and you visit online forums, then you probably know that the correct number of bikes is n+1. I got a new bike this year, but it was partly to replace the cargo carrying capabilities I lacked after selling my Yuba Mundo in the spring.

Two weekends ago I passed by the Chicago Transit Authority headquarters to test if my WorkCycles Fr8 could fit in the Sportworks VeloPorter 2 bus-bike rack the CTA uses on most buses (it’ll eventually replace the red ones). I don’t know if Pace buses have the same model.

It fits! (I feel like saying “It blends!”)

I already knew that the WorkCycles Transportfiets would fit, having made a video of it last year. But they seemed to be of different dimensions (they probably aren’t) and I wanted to check ahead of time lest I embarrass myself and delay a bus if I tested it in the field.

Actually, I wasn’t worried that the Fr8 wouldn’t fit, I was worried that it wouldn’t fit securely under the spring-tensioned arm with the yellow grip. I have a burly front rack and metal fenders that wouldn’t be able to budge. See how that worked out for me in the photo below. Additionally, my bike weighs 50 pounds unloaded (and without the red basket) – the Sportworks specifications note that each bike tray holds 55 pounds. Phew!

Last weekend I took the Fr8 on its first ever train journey, from the Clinton Pink/Green Line station to the California Pink Line station. The Pink Line uses the 5000-series cars, which are brand new from Bombardier’s factory in New York. They have the distinction of providing two wheelchair-accessible spaces in every car instead of one. This means there are two fewer “modesty panels” in the vestibule. It offers more room to position and park your bike – it works out great; see photo below. It still doesn’t provide enough room for a passenger to bring a bike aboard, stay put, and let other passengers in and out of the door. Passengers with bikes will still need to pay attention to the announcements to know which door will open at the next station and move their bike accordingly.

Looking for a WorkCycles of your own? You can contact them directly in Amsterdam. Shipping is €200, which is a really good deal now. You can also contact J.C. Lind Bike Co. who will become a dealer soon.

Finding a new way to measure cities’ bike friendliness in the United States, part 2

November 5, 2012 / / 0 Comments

One of the reasons I developed my own bike friendly city ranking system was to provide a better measurement when comparing cities. Since the League of American Bicyclists (LAB) uses a nominal ranking (Platinum, Silver, Gold, Bronze), the difference in bike friendliness between cities of the same rank may be small or great. A numerical scoring system on a predictable and familiar scale will better highlight the distance of one city to another on achieve that city’s level of bike friendliness.

I created a method that would compare my ranking to LAB’s ranking and that was to find the variance (which isn’t the same as range) in scores in my ranking for each nominal level in LAB’s ranking. Platinum cities had a very high variance and Bronze cities had the lowest variance. Gold and Silver had swapped positions: Gold cities had a lower variance than Silver cities.

The beauty with creating your own bike friendly measurement system is that you can make the outcome order whatever you want.

In the days since, I’ve developed another bike friendliness measurement system, one that’s easier to understand, whose rankings are still relative to other cities, and that can be weighted. (I’m emphasizing the bike commute mode share.) It uses percentile scoring so all scores are positive but still based on the distribution of values. I’ve listed the scores for Method 1 (which uses a normalizing function based on mean and standard deviation) and Method 2 below.

Mode share by trip miles and trip frequency in Chicago and Cook County

Two tables in this post. Data from the Chicago Metropolitan Agency for Planning’s 2008 Travel Tracker Survey. Download source file (pdf).

Table 1. Number represents share of trip miles taken by that mode. So in Central Chicago (which seems to comprise neighborhoods as far north as Uptown and as far south as Hyde Park), 1.4% of all trip miles are by bike. If 1,000 people take 100 trips of 2 miles each, then 2,800 miles will be by bike.

Table 2. Number represents share of trips taken by that mode, regardless of distance.

Finding a new way to measure cities’ bike friendliness in the United States

A really smart person could come up with a way to measure day-to-day bike friendliness based on how well cities adhere to standards that keep roads clear of obstructions that further frustrate the commute, like construction projects that squeeze bikes and cars together. 

I work at home. There are some days when I only leave my house to get milk from the Mexican grocery store at the end of my block (which makes awesome burritos). That means I ride my bike half as much as people who commute to work. on their bikes. Today I had a bunch of errands to run: drop off stuff, buy stuff, take pictures of stuff for my blog, Grid Chicago.

It was a very frustrating experience. I don’t need to go into details about how I was harassed by people who the state so graciously awarded a license to drive. But it happened. And it happens a hundred times a day to people cycle commuting in Chicago. I got to thinking about “bike friendly” cities. Is there a way to incorporate driver attitudes in there? I tweeted:

[tweet_embed id=264575958374305792]

Later I had the idea to use some very simple but objective measurements to create a new bike friendliness metric. It would help ensure that “Silver” (a ranking the League of American Bicyclists [LAB] uses) in one city means the same as “Silver”. It can expand from here but basically it works like this:

  • The share of people going to work who go by bike is a proxy for how “friendly” a city is to biking.
  • If a city has a lot of people biking to work, it must be friendly.
  • If a city has a few people biking to work, it must be non-friendly.
  • Cities are compared to each other to determine friendly and non-friendly.
  • The metric uses standard deviation to score cities.

Stop me if this has already been done.

I created a spreadsheet that lists the top 10 populous cities in the United States. I then added 10 more cities: Austin, Boston, Davis, Madison, Minneapolis, Portland, San Francisco, Seattle, and Washington, D.C. In the next column I listed their bike commute share from the American Community Survey 2006-2010 5-year estimates. I calculated the standard deviation and mean of these shares and then in another column used Apple Numbers’s STANDARDIZE function:

The STANDARDIZE function returns a normalized value from a distribution characterized by a given mean and standard deviation.

I think that’s what I want. And the output is close to what I expected. I then found the LAB ranking for each city and found the variance of each ranking to see how far apart each city within one ranking was from another city in the same ranking. The results were interesting: the higher the ranking, the more variance there was.

Hurricane Sandy prompted a lot of New Yorkers to bike. It made headlines, even. Photo by Doug Gordon. 

I wanted to add another metric of bike friendliness, and that’s density. To me, a higher density of people would mean a higher density of places to go (shop, eat, learn, enjoy) and friends and family would be closer, too. Or the possibility of meeting new people nearby would be higher. Yeah, I’m making a lot of assumptions here. So I applied the STANDARDIZE function there as well. I added this number to the previous STANDARDIZE result and that became the city’s score.

So, in this new, weird ranking system, the most bicycle friendly cities are…drum roll please…

  1. Davis, California (Platinum)
  2. New York City (Silver) *
  3. San Francisco (Gold) *
  4. Boulder (Platinum)
  5. Boston (Silver)
  6. Philadelphia (Silver)
  7. Tie: Chicago*, Washington, D.C. (Silver)
  8. Tie: Portland* (Platinum), Minneapolis* (Gold)

Remember, I said above that any author of a list should spend at least a day cycling in each city. I’ve starred the cities where I’ve done that – I’ve cycled in 5 cities for at least a day.

I only calculated 20 cities. Ideally I’d calculate it for the top 50 most populous cities AND for every city that’s been ranked by LAB.

New Honda commercial tells people it’s okay to drive their car while sleepy

October 31, 2012 / / 10 Comments

Eff you, Honda.

Partial transcript:

We know you.

[Shows guy yawning.]

We know you have to rise early and work late.

[Shows someone drinking coffee. Shows “Lane Departure Warning” signal and an obscured person driving on a rural road driving their Honda Accord in the opposite direction lane, then swerving back into the correct lane.]

With not enough sleep in between.

[Shows hands of driver moving the steering wheel to maneuver the car back into the correct lane with driver’s shoulders moving dramatically to either show that the steering wheel had to be yanked or that he’s shrugging off the moment.]

The rest of the commercial shows different features and makes stupid comments about your needs and desires.

It’s not okay to drive in that condition.
