The Latest From BostonBiker.org

In Manhattan they did anyway, with the help of more pedestrians and higher transit rates, as well as the new bike share program.
After several blocks in the heart of Times Square were pedestrianized and protected bike lanes were added to five avenues in the middle of Manhattan, motor vehicle traffic is actually moving more smoothly than before, according to the latest release of NYC DOT’s annual Sustainable Streets Index [PDF].
The report, which gathers data from the MTA, the Taxi and Limousine Commission, and DOT’s own counts, also shows that the volume of traffic entering Manhattan has basically stayed flat since 2009. At the same time, transit ridership has started to rebound from the recession and service cuts.
Even with population and employment levels increasing after the recession, car traffic into the Manhattan CBD declined 1.7 percent in 2011. Since 2003, traffic volumes are down 6.5 percent, while transit trips to the area have increased 11.3 percent.
The annual report incorporates numbers on bike-share usage. Between the Memorial Day launch and August 26, Citi Bike riders made more than 2.5 million trips covering more than 5.5 million miles. There have been eight crashes involving Citi Bikes, none causing injuries classified as serious. Of stations sampled during the final two weeks of July, the busiest included those near hubs like Grand Central Terminal and Union Square.
Read the rest of this fascinating article here. It seems obvious that if you take a bunch of people out of cars and instead they take public transit/ride a bike/ or walk that traffic would move better, but its always nice to see some real world data to prove it.
What I think is the real take home from this study is that peoples lives are improving. They are being more healthy (even public transit is healthier than driving). They are saving money, they are reducing their impact on the planet, and even the people who are still trapped in their cars are happier because traffic is moving smoothly. I honestly wouldn’t be surprised if they were happier as well. Its a win win win win.
People defend cars, and get very upset when you try to make it harder to use them, but they really have so very few benefits and so very many drawbacks. I think what we are seeing is that this fact is finally sinking in.
Thanks Ben for the heads up on this.

A recent study by MIT and UC Berkely using anonymous cell phone data and gps have determined that it is just 15 areas in the Boston metro area (out of 750 tracked by the census) are causing almost all of the traffic jams in Boston.
What they found, perhaps surprisingly, is that during rush hour, 98 percent of roads in the Boston area were in fact below traffic capacity, while just 2 percent of roads had more cars on them than they could handle. These congested roads included short stretches of I-495 southbound and Route 128 southbound, a number of downtown streets, and a wide scattering of suburban arteries, such as Bridge Street in Lowell (southbound) and Water Street in Haverhill (northbound). Each of these roads has what the engineers term a high degree of “betweenness”—that is, they’re essential for connecting one part of the metropolitan area to the others.
The backups on these roads ripple outward, causing traffic to snarl across the Hub. Marta Gonzalez of MIT, one of the lead engineers on the study, explains the effect this way. “The analogy we make is of your circulatory system,” she says. “When you have one artery that is blocked, it will affect your entire circulation.”
By tracking the cell records, they found that it’s just a small number of drivers from a small number of neighborhoods who are responsible for tying up the key roads. Specifically, they identified 15 census tracts (out of the 750 in Greater Boston) located in Everett, Marlborough, Lawrence, Lowell, and Waltham as the heart of the problem, because drivers from those areas make particularly intensive use of the problematic roads in the system.(via)
What this says to me is that, if we could connect these areas to decent public transportation and cycling options we could eliminate large amounts of traffic in this town. By working smarter, not harder, we could burst the bubble of traffic with laser guided improvements to our infrastructure.
The study demonstrated that “canceling or delaying the trips of 1 percent of all drivers across a road network would reduce delays caused by congestion by only about 3 percent,” MIT wrote. ” But canceling the trips of 1 percent of drivers from carefully selected neighborhoods would reduce the extra travel time for all other drivers in a metropolitan area by as much as 18 percent.”
The effectiveness of this “selective strategy” is attributed in the study to the facts that “only [a] few road segments are congested” and that these road segments are clogged by people originating largely from only a few areas. Even though data was anonymous, researchers were able to infer drivers’ home neighborhoods “from the regularity of the route traveled and from the locations of cell towers that handled calls made between 9 p.m. and 6 a.m,” UC-Berkeley said.(via)
If we can get drivers in these targeted areas to bus/train/cycle to work, we could dramatically reduce traffic in the rest of the town. Combined with some sort of congestion tax to keep otherwise non-car drivers from filling in the empty space made by the reduction of traffic, and using the money from that and a re-organized tax system to fund improvements in public transportation infrastructure, we could be living in a very pleasant city devoid of most single occupancy car drivers.

The good folks at ABC are trying to keep tabs on the Craigie Bridge construction (which PS. starts next Friday).
Got this in the email
Dear Boston bicycle and pedestrian community,
Anybody commute or ride regularly on the Craigie Bridge? If so, can you get in touch with me? Here’s what I’m trying to find out:
1. Start and Destination?
2. Do you take an alternative bridge / route?
3. The construction on the Craigie is starting the night of Friday, Nov. 5th. Like the BU bridge, the Craigie is supposed to remain open to bikes and peds throughout construction. Can someone confirm this?
A Better City is working on a bridge construction / traffic advisory website for all forms of transportation. Any input would be greatly appreciated!
I assume you can contact them here or you can leave them in the comments here and I will have them take a look.

Thanks to Erik for pointing this out to me.
It’s great, watch it twice and think hard. Also read this book its fantastic.
