Pollution fighting bike lane, coming soon to Pilsen

October 27, 2009 / / 0 Comments

Rendering of the project by CDOT. See all photos about this project.

A planner from the Streetscape and Sustainable Design Program in the Chicago Department of Transportation (CDOT) came to speak to my Sustainable Development Techniques class at UIC about adding “green” to urban design.

Among other topics, he talked about CDOT’s streetscape project for Cermak and Blue Island in Pilsen, a near southwest side neighborhood a couple miles outside of downtown Chicago. The project, like all streetscapes, is one of economic development. But this project is unique in that the goal was to look at every element and make each as green and sustainable as possible.

You can read about the project through the Program’s presentation here (Flash slideshow). Please note there are many versions of the same presentation on the web and each my be different depending on their intended audience.

I will be discussing a single showcase element from the project: A bike lane on Blue Island between Ashland and Western where currently one does not exist. The bike lane and the adjacent parking lane (on the bike lane’s right side, as normal in Chicago) will be constructed with permeable pavers mixed with smog eating concrete. Wait? Smog eating concrete? Keep reading!

The bike lane will begin at Ashland/Cermak/Blue Island, a well-traveled intersection for heavy trucks, three bus routes, and many passenger cars. The bike lane will connect Pilsen to Little Village and extend the existing bike lane on Blue Island in Pilsen’s central shopping area. This segment is also a designated truck route and to safely accommodate the parking lane, bike lane, and travel lane, the road will be widened by reducing the width of the sidewalks. The sidewalks here are 20 feet wide, double the standard width, and four times wider than sidewalks in many parts of Chicago. There’s very low pedestrian volume here and very little residential use so the plan is to have 8 foot wide sidewalks, and a 5.5 foot planter, breaking occasionally for bus stop shelters.

The bike lane will be 5 feet wide (including striping) and the parking lane will be 8 feet wide. The novel part of the two lanes is that they will be made with permeable pavers.

This will be the first paver bike lane in the City of Chicago. The blocks will be oriented so that bicyclists feel the least amount of bumps and won’t get their tire stuck in a groove that could harm.

The smog eating concrete’s trade name is TX Active, invented by Italcementi Group, a large, multinational corporation founded and based in Italy. Since the original installation of TX Active cement on the Dives in Misericordia Church in Rome (designed by Richard Meier), Italcementi has developed two lines of photocatalytic cement, only one of which reduces pollutants in the area (TX Arca). The other cement is for architectural uses helps keep the concrete surface clean from dirt and particulate matter.

CDOT will use the second line, TX Aria, in the top half inch of the pavers. The company has tested the product to demonstrate its effectiveness at reducing the presence of Nitrogen Oxides (commonly written as NOx, a family of toxic substances emitted by internal combustion engines) and published its laboratory results in an easy to follow report on its website (PDF). The technical report goes into more details and explains how the process works (through photocatalysis) and what substances their product can be designed to diminish. The technical report is unclear on whether or not all forms of the TX Active product abate all substances. It may be that the maker only tested its effects on Nitrogen Oxides levels.

I look forward to watching the construction progress and to breathing the cleaner air while bicycling to a new destination in Pilsen.

A LEED-related homework assignment and my response

October 7, 2009 / / 0 Comments

The assignment: Write a mock letter to the editor responding to this New York Times article: Some Buildings Not Living Up to Green Label (published August 31, 2009).

The class: Sustainable Development Techniques

How the class works: The professors invite working professionals to speak to the class each week. After the lecture from these guests, a short discussion ensues. The guests design the homework questions. The following week, the class discusses their responses with each other and the professors.

Dear Editor,

Buildings, as a category, consume more energy than any other category in the United States. The USGBC: U.S. Green Building Council (GBC) took the right steps by mandating an energy efficiency minimum to receive LEED certification. As it increases the standard building designers and owners need to reach to achieve the image of “green” or environmental responsibility, we should look for ways to make green building design cheaper and easier.

I have a few suggestions for how we can make that happen, but first I want to encourage your newspaper and its readers to send a message to their Congresspersons: They should pay attention to the fact that buildings consume the most energy of any category of energy use and include a section in climate change legislation that reduces buildings’ impact on the environment and their contribution to greenhouse gas emissions. Climate change legislation will not be effective unless it mandates and encourages changes in buildings and how they use energy.

So how can we make LEED certification (or other similar certification programs) easier to achieve? First of all, do not reduce the ease of certification. This will have an ill effect on climate change and reverse the positive advances LEED and its certified buildings make.

  1. Certify buildings who meet the minimum energy efficiency requirements with a new label. Some building owners or developers may not care to receive full certification or medal, or create green roofs or offer alternative transportation to building workers, but would rather be recognized for making bona fide improvements to their energy systems and use. Hold the buildings to the same reporting standards as all other certification levels.
  2. Support and fund research that will be used to continually refine the certification process and identify the best and worst energy system changes and upgrades. The Center for Neighborhood Technology and the New Buildings Institute have researched LEED-certified buildings to gauge their energy use and determine how effective the buildings are in reducing energy use (not all buildings were able to reduce energy use).
  3. Offer short-term rewards when people make long-term changes that provide long-term benefits. Provide instant or near-instant tax rebates when residents who live in or own “energy poor” buildings and make upgrades that are proven to increase the building’s energy efficiency by a minimum amount. When people can see immediate benefits, they may be more likely to make the changes. Make the rebate requirements easy to understand – consult with retailers like CVS and Walgreens who provide some rebates immediately to their customers after a purchase is made. However, consult the best universities and researchers to ensure the program managing this system will not allow rebates for window installation when home insulation negates any positive effect the new windows would provide.
  4. Continue to provide support and funding for “green jobs” that will further these legislated programs. Jobs like researchers, product development, engineering; also, new jobs like “energy efficiency inspector” and consultant.
  5. Mandate programs that reduce the Top 10 energy wasters in offices so that individual workers must play a part in their building’s energy reduction. This might mean automatic computer suspension overnight and on the weekends, or eliminating paper intensive processes, or installing automatic hand dryers and lights. These programs should apply to every building with at least 10 workers. Be imaginative, though, to work around corporate resistance; perhaps a cap & trade element would satisfy some building lessees.

Please continue writing about this issue. I want all workers to be aware of how they use energy and contribute to their building’s energy use and how it relates to carbon emissions.

-Steven Vance

I believe that most letters to the editor are written in mind for the newspaper’s other readers. Many letters to the editor are indeed directed at the editor, the article author, or the newspaper as a company. I chose to write my letter in the former style because if I was going to be published where 800,000 people might read what I wrote, I want it to be something they will find interesting and can have a personal response.

Why did I write what I did? Two LEED experts at Center for Neighborhood Technology in Chicago, Illinois, came to speak to my class about their research project that analyzes energy and water usage for 27 LEED-certified buildings in Illinois (find buildings on the USGBC’s website). The twofold purpose is to provide a report back to the study participants about their consumption, but also point out exactly what the NYT article mentioned: there’s a disparity between LEED certification and energy efficiency. Should LEED standards be more stringent about energy reduction (for existing buildings) or efficiency (for new buildings compared to other buildings in its class)?

It turns out that U.S. Green Buildings Council will soon require that new buildings must meet a certain minimum number of points in the Energy Efficiency category. I agree with this change, and my suggestions in my letter to the editor complement that change and encourage making energy efficiency easier and something that individual homeowners and workers will take part in.

The importance of sharing data in KML format

October 5, 2009 / / 0 Comments

The KML file is an important format in which to share locational data. KML was developed by a company called Keyhole, which Google purchased in 2004, and subsequently released Keyhole’s flagship product: Earth.

A Keyhole Markup Language file is a way to display on a map (particularly a 3D globe of Earth) a collection of points with a defined style. Google has added more functionality and style to the KML format, expanding the styles that can be applied and the information that can be embedded.

KML, like XML (eXtensible Markup Language), is extremely web-friendly. For a web application at work I developed, I included this PHP class that creates an KML file on-demand based on a predefined database query. The file contains locations and attributes of recently installed bike racks in Chicago. EveryBlock imports the file and its information into their location-based service, aggregating many news types around your block.

But a KML file is more important than being the native file for use within Google Earth. It’s an open source text file that can be manipulated by a number of software programs on any computer system on earth (or read on a printed page). It’s not encoded, like shapefiles, so I can read the file with my own mind and understand the data it would present in a compatible map viewer. I see lines of organized syntax describing points and polygons, listing their attributes in plain language.

Have you ever tried to see the “inside” of a shapefile? Only GIS programs can read them for you. KML provides data producers and consumers the opportunities to keep data open, available, and easy to use. We need locational data for our work, and we need tools to help us use it, not hide it.

What the Census says about bicycle commuting

September 26, 2009 / / 0 Comments

UPDATE 11-08-10: I wrote a post comparing the commuting statistics between Chicago, Minneapolis, and St. Paul.

UPDATE 02-12-11: Added 2009 data.

Prompted by this entry on BikePortland about the rise of bicycle commuting and the bicycle mode share in Portland, Oregon, I decided to research what the American Community Survey says about the mode share of bicycles as part of commuting where I live: Chicago. I’ll also post bicycle’s share of commuting for other locales, as well.

Some definitions, first:

  • Commuting means travel to and from work – the Census Bureau calls this “MEANS OF TRANSPORTATION TO WORK.” The Census Bureau does not collect information on travel to shopping, medical services, and other places in the decennial census or the yearly American Community Survey (which will supposedly replace the decennial census).
  • Block means the smallest area for which the Census Bureau reports statistics. Any smaller and the possibility that someone could personally identify you from the responses increases. Find your block. The American Community Survey reports information for much larger areas: In some cases, researchers can only select data at the county level. The Census Bureau provides information for the City of Chicago and other municipal divisions of many counties in Illinois.
  • Subject definitions. These describe the question asked to participants and include clarifying information in the case the participant doesn’t understand the question, or their answer is complex. Download the subject definitions for the 2008 American Community Survey.
  • Margin of error (MOE) means the high and low end of confidence. Read more about margin of error on the Census Bureau’s website.

For the American Community Survey, I found table S0801, Commuting Characteristics by Sex. In the decennial census, I found table  P30. MEANS OF TRANSPORTATION TO WORK FOR WORKERS 16 YEARS AND OVER. If you want to check my research, look for these tables of sample data.

Chicago:
Margin of error for male and female categories varied. Combined always reported 0.2%.

  • 2009 – 1.1% travel to work by bicycle. 1.8% male (MOE: 0.3%), 0.4% female (MOE: 0.1%). Workers over 16: 1,271,744. Permalink.
  • 2008 – 1.0% travel to work by bicycle. 1.5% male (MOE: 0.3%), 0.5% female (MOE: 0.2%). Workers over 16: 1,260,741. Permalink.
  • 2007 – 1.1% travel to work by bicycle. 1.4% male (MOE: 0.3%), 0.7% female (MOE: 0.2%). Workers over 16: 1,230,933. Permalink.
  • 2006 – 0.9% travel to work by bicycle. 1.2% male (MOE: 0.3%), 0.7% female (MOE: 0.2%). Workers over 16: 1,209,122. Permalink.
  • 2005 – 0.7% travel to work by bicycle. 0.9% male (MOE: 0.1%), 0.4% female (MOE: 0.1%). Workers over 16: 1,162,550. Permalink.

United States:
Margin of error happened to be the same for each reported category (combined, male, female).

  • 2009 – 0.6% travel to work by bicycle. 0.8% male, 0.3% female. MOE: 0.1%. Workers over 16: 138,591,804 (decrease). Permalink.
  • 2008 – 0.5% travel to work by bicycle. 0.8% male, 0.3% female. MOE: 0.1%. Workers over 16: 143,995,967. Permalink.
  • 2007 – 0.5% travel to work by bicycle. 0.7% male, 0.2% female. MOE: 0.1%. Workers over 16: 139,259,684. Permalink.
  • 2006 – 0.5% travel to work by bicycle. 0.6% male, 0.2% female. MOE: 0.1%. Workers over 16: 138,265,905. Permalink.
  • 2005 – 0.4% travel to work by bicycle. 0.6% male, 0.2% female. MOE: 0.1%. Workers over 16: 133,091,043. Permalink.

Read the BikePortland article if you want to know that Portland has a higher share of commuters traveling by bicycle than Chicago has.

And what about my block? As I mentioned above, we can only find information at the block group level in the decennial census. I live in Block Group 1 of Census Tract 6009 in Chicago, Illinois. I didn’t live here in 2000, though, the last time the decennial census occurred. Back then, out of 168 workers over 16, 4 of them rode their bikes to work! That equals .024% of the worker population in my block group. Oddly, though, the Census Bureau reported 946 people living in this Block Group. Looking at table P8 (Sex By Age), I see that 674 have at least 16 years of age. 178 people have at least 55 years. Does this mean a lot of people in the Block Group didn’t work at the time of the survey in 2000? I don’t know. Permalink to data.

By far, though, driving alone won as the most popular way to get to work: 71.423% of the worker population.

Bicycling for college students

September 2, 2009 / / 0 Comments

I write this article to all college students who choose to bike to class this semester (and any future semester). This post is a bit Chicago-centric, but can be applied universally.

Introduction

If you haven’t yet chosen to bike to campus, don’t read this – I’ve got another article in the works for you. Essentially, I gained my advice and education from information I found in multiple documents published by the Chicago Bicycle Program. But you can read my post in less than 10 minutes. I give my friends the same spiel, and now I’ve finally published it for everyone’s benefit.

My credentials: I’ve been commuting safely and effectively to the University of Illinois at Chicago campus for four years, attending undergraduate and graduate class. I’ve been bicycling all around Chicago (I can prove it with these maps) for the same period.

I divide my advice into three sections: Safety, Getting There, and The Right Equipment. You should have a copy of the Chicago Bike Map at your side (download as PDF; tambien disponible en espanol; request one to be mailed).

Safety
Safety is a combination of skills, following the rules of the road, and being alert.

You gain safe cycling skills by practicing safe cycling at all times on all roads upon which you cycle.
You most likely learned the rules of the road in high school driver’s education.

Bicyclists must follow the same traffic regulations as motorists (including stopping at yellow and red traffic lights). Additionally, you should practice several additional behaviors (found in the Sharing The Road section of the Bike Map):

  • Never ride against traffic. Bike Snob NYC calls this “bike salmoning.” No other road user expects vehicles to travel in the wrong direction, making this one of the most risky maneuvers.
  • Don’t ride on the sidewalk. You’re disrupting pedestrian traffic and it’s illegal.
  • Know about the door zone: the 4-feet invisible space on both sides of every vehicle that represents the width of a door swinging into a bicyclist’s path. Watch for recently parked cars and cars with people inside.
  • Lastly, ride in a straight, predictable line, and not weaving between parked cars in the parking lane. Passing motorists and bicyclists can safely travel past you because they know where you’re going.

Staying alert will help you avoid collisions and prevent you from getting boxed in by CTA buses. Part of being aware is being able to hear: Don’t use headphones while bicycling (this too is illegal).

Wanna see these tips in action? Watch the CDOT/Chicago Police video on traffic enforcement for bicyclist safety.

Getting There
You can journey safely by determining the best way to get to your destination. Mark your origin (home) and destination (school) on the bike map and then follow the bike lanes, marked shared lanes, and recommended routes to the end. Practice your trip with a friend during the day.

Indoor, sheltered bike parking at the recently reopened Damen Brown Line station.

Also consider making a multi-modal trip using transit. All CTA stations in Chicago have bike parking, and most Metra stations have bike parking. A bus will carry your bike for you at any time, and you can take your bike on the L outside of rush hours.

*More information on bikeway facilities in Chicago below.


The Blue Island bike lane on my way to class from Pilsen.

Try your hardest to never let a motorist scare you off the road with their hurtful and pointless words (or honking). You have the right to bike on the street. If you get into a verbal altercation with a motorist, TAKE A BREAK. Your adrenaline and heart rate will have increased, and emotions may decide your next move. Pull over and breathe. You need to stay in control of you, your bike, and your trip. If the motorist is operating their vehicle that’s a danger to you or other street users, pull over and immediately call 911 to report reckless driving.

Additionally, college campuses often have a lot of buses (either public transit or shuttles). Let the bus driver “do their thing” and don’t try to compete for space with the bus. Wait or signal and pass safely in the adjacent lane.

The Active Transportation Alliance, the Chicago bike advocate, has a crash support hotline: 312-869-HELP (4357).

The Right Equipment
To bike somewhere safely, you need the right equipment:
LIGHTS and a LOCK. Right now, throw away your cable lock. It’s completely useless unless part of a locking scheme that includes a high-quality u-lock.

Buy the most expensive, new u-lock you can afford. You spent a lot of money on your bike, so you should spend a little money on the device that will keep your bike yours! Once you buy, learn how to use it by following these depictions.

Chicago law requires a headlight, and a rear reflector or taillight. Forget the rear reflector – it’s close to worthless. You want road users to see your presence. So get two blinkies: a white light for the front, and a red light for the rear (with a rear light, you’ll be honoring the law). These two accessories will make you visible. Bike shops shouldn’t let you leave until you buy these or prove you already own a set.

If you want be really visible, you can get cold cathode fluorescent lights for your bike. I built this setup as a fun, DIY project.

More equipment you may want:

  • Fenders. Keep your feet and pants dry.
  • Water bottle cage. Being outside and active dehydrates your body.
  • Rear rack or front basket. Shuck your backpack into a basket to keep sweat off your back and reduce back pain.

*The bike map’s road designations are based on actual field observations completed several years ago by City and Active Transportation Alliance staff. Bike lanes, indicated by two white stripes, a bicycle symbol, and an arrow, are for the exclusive use of bicyclists. Marked shared lanes, shown with a bicycle symbol and two chevrons, tell motorists and bicyclists that this is a shared lane and motorists should expect a higher number of bicyclists than most streets. (All lanes in Chicago are shared lanes and bicyclists ALWAYS have the right to use the entire lane when the bicyclist feels they cannot safely share the lane with a motorist, or when changing lanes.)
