Hug and a Helmet
Check out this video where Danish police officers stop cyclists en route who are not wearing the proper safety gear to offer a hug and a helmet.

Parking Deck Blows in the Wind
I saw Ned Kahn speak at SCAD last night and was totally blown away (pardon the pun) by his work. Ned is an environmental artist and sculptor from Northern California who has completed ambitious public artworks for private and public organizations, both as a solo artist and in collaboration with architects and engineers across the U.S. and Europe.Kahn won a MacArthur Foundation "genius award" in 2003 and the National Design Award for environmental design in 2005. Below is a video of a piece Ned did in Charlotte, NC where he covered the facade of a parking garage with 80,000 small aluminum panels that are hinged to move freely in the wind.
Wind Veil (Video)
Viewed from the outside, the entire wall of the building appears to move in the wind and creates the impression of waves in a field of metallic grass. Inside the building, intricate patterns of light and shadows, similar to the way light filters through the leaves of trees, are projected onto the walls and floor as sunlight passes through this kinetic membrane.
In addition to revealing the ever-changing patterns of the invisible wind, the artwork was designed to provide ventilation and shade for the interior of the parking garage. The piece was commissioned by Bank of America and completed in August 2000.

Carpooling in the 21st Century
I was recently thinking about carpooling and how it has evolved over the past decade or two. Carpooling used to be something you could only do in person. You had to know someone (co-worker, neighborhood or family member) who happen to be going in the same direction.
Then came ridematch databases that matched people within a certain employer or area. Sure, you did not know the person, but you could take comfort in that they were like-minded and employed.
Today, you can arrange carpooling online at http://www.goloco.org/ and http://www.erideshare.com/. These services allow for all types of trips (e.g. employee, special events, grocery store) in real time using your Internet phone. The online carpooling is just in the infancy stage, but you can imagine in 20-30 years when 15% of an urban area is looking for a ride. One thing all of this traditional carpooling has in common is that it involves prearrangement through some mechanism, such as online or work-based matching. Still, the future seems to hold the prospect of a system designed around carpooling without prearrangement (two types of carpooling without prearrangement have been going on for some time in Washington D.C. and San Fransisco). This is called fexible carpooling. Learn more about it here.

Transit oriented developments may create fewer car trips than thought
Opponents of high-density, transit-oriented developments (TODs), often claim they create more of a traffic problem than they solve. But new research shows the number of trips they create is often exaggerated by as much as 50%.
First, a little background. Transportation planners struggle with how to reliably predict the number of net vehicle and person trips generated by new or infill mixed-use development such as TODs. Since the old model has relied primarily on single-use, free-standing sites, it is very difficult to make predictions with any certainty. Add to the mix internal capture rates, and the level of uncertainty rises.
The Institute of Traffic Engineers (ITE) is the only one to suggest a framework for establishing a data collection procedure for estimating multi-use trip generation to include internal capture rates. However, this framework is based on even more limited information than the old model. Currently, "...so little information is available about internal capture rates that traffic impact studies for mixed-use developments become little more than exercises in speculation." (Ewing, R., M. Deanna, and S.C. Li, Transportation Research Record 1518, pp. 1-6).
New research recently completed for the Transit Cooperative Program seems to confirm the disconnect between the modeling and the actual demand. The research confirms that the ITE trip generation and parking generation rates over estimates automobile trips for TOD developments by as much as 50%.
To view the actual study go to the TCRP website or check out this synopsis from on Planetizen.

GDOT fantasy threatens to scuttle BeltLine reality

There they go again, flexing their muscle instead of their brains. GDOT has built roads in the same fashion for the past 100 years in Georgia, and now they are bringing the tactic to alternative transportation. It appears GDOT wants to grab a piece of the BeltLine for their commuter rail/high speed rail fantasy with no regard to the City of Atlanta and their plans for the Beltline.
Jay Bookman writes in the AJC that the DOT does not have a good record of following through on its commuter rail plans.
Jay Bookman writes in the AJC that the DOT does not have a good record of following through on its commuter rail plans.
For example, an environmental assessment of a downtown multimodal station was completed back in 1995, the same year DOT completed its so-called “Commuter Rail Plan Final Report.” But nothing has happened to make those plans real.If only GDOT's ambitions for alternative transportation were the same as for building roads, hen we might have a world class transportation system in no time.
In fact, an $87 million federal appropriation for commuter rail between Atlanta and Lovejoy has been sitting untouched for more than five years, awaiting matching money from the state that has never come.

President Obama vows new focus on transit
On this historic day, a reminder of President Obama's stated positions on energy efficient public transportation.
http://www.barackobama.com/pdf/issues/FactSheetTransportation.pdf
I look forward to exploring each of these in the months to come.
http://www.barackobama.com/pdf/issues/FactSheetTransportation.pdf
Create Greater Incentives for Public Transit Usage: The federal tax code rewards driving to work by allowing employers to provide parking benefits of $205 per month tax free to their employees. The tax code provides employers with commuting benefits for transit, carpooling or vanpooling capped at $105 per month. This gives drivers a nearly 2:1 advantage over transit users. Obama and Biden will reform the tax code to make benefits for driving and public transit or ridesharing equal.
Strengthen Metropolitan Planning to Cut Down Traffic Congestion: Our communities will better serve all of their residents if we are able to leave our cars, to walk, bicycle and have access other transportation alternatives. As president, Barack Obama will re-evaluate the transportation funding process to ensure that smart growth considerations are taken into account. Obama will build upon his efforts in the Senate to ensure that more Metropolitan Planning Organizations create policies to incentivize greater bicycle and pedestrian usage of roads and sidewalks. As president, Obama will work to provide states and local governments with the resources they need to address sprawl and create more livable communities.
Require States to Plan for Energy Conservation: Obama and Biden will also reform current law which simply asks governors and their state Departments of Transportation to “consider” energy conservation as a condition of receiving federal transportation dollars. As president, Obama will require governors and local
leaders in our metropolitan areas to make “energy conservation” a required part of their planning for the expenditure of federal transportation funds.
I look forward to exploring each of these in the months to come.

Zipcar chief on CNBC
Zipcar Chief Executive Scott Griffith appeared on CNBC this week to explain why "cars on demand" makes sense for people who live in cities and don't need a car all the time.
http://www.cnbc.com/id/15840232?video=996618094
He points out that Zipcar is not only for transit-oriented cities like New York. It is exceeding expectations here in Atlanta, where Lanier Parking Solutions is Zipcar's joint-venture partner, having brought the concept to the city in 2006.
