It’s well past time to rethink how we power our transportation system.
Change the way you live, change the way you vote, its time to save the planet for ourselves and our children.

For the last 7 or so work days I have noticed that on my morning commute, there are significantly more cyclists than their are motorists. The insane part of it is, the cars still take up vastly more room.
You will pull up to a red light and see 10 cyclists crammed into the tiniest little area, and next to them 3 people in cars taking up the entire road. The light changes green and all the cyclists cram into a narrow bike lane (happily I might add), while the 3 or 4 cars struggle to find room on roads clogged with on street parking and construction.
There are two lessons I have learned form this.
1. WE ARE WINNING! Cycling is clearing a preferable form of transportation, this is due to many peoples hard work promoting cycling infrastructure and education.
2. Driving a car is about the dumbest way to get to work. If you don’t have a really good reason, leave the 4 wheel vehicle at work, dust off that bicycle, and join the crowd!
Have you seen an uptick in the number of cyclists on your commute? Have you noticed that you are outnumbering cars? Let me know in the comments.

The statistics show that each of us is driving less. So why do our roads feel more jammed up? Why does it take longer to get anywhere? And what can we do about it? Some politicians have begun blaming Traffic Calming and bicycle lanes for the backups; saying that Complete Streets and pedestrian bulb-outs are making roads less safe because less accessible for emergency vehicles. Is there any truth to this? More fundamentally, is car congestion a problem to be solved or a solution to a problem?
A 2013 report from US PIRG showed that the average number of miles driven by the average American has been falling for about a decade, through economic booms and busts, and was down to mid-1990s levels. Millennials, our nation’s largest-ever generational cohort, are using transit and bikes more and taking fewer and shorter car trips, resulting in a 23% drop in the average number of miles driven. The percentage of high school seniors with a driver’s license fell 12%. Walkable city life is increasingly attractive to both young people and retiring baby boomers. The rise of on-line shopping, social media, and telecommuting has meant fewer quick car trips.
Despite these trends, as every driver knows, our roads are increasingly congested – not everywhere or all the time but for increasing periods at a growing number of key intersections and road segments. Congestion radically reduces the volume of traffic passing through a road section, the through-put, thereby creating a negative feedback loop that creates more backups. It’s estimated that USA drivers spend about 14.5 million hours every day stuck in traffic. Congestion not only costs us time – in 2011 Boston drivers collectively lost about 137 million hours, or about 53 hours per commuter per year – but also fuel and therefore pollution, health, and money. Not to mention frustration and occasionally murderous road rage. Although we Bostonians believe we’ve got it worst, car congestion seems to be clogging roads like kudzu in nearly every city in the country – and, by some reports, across the globe .
It’s true that a new report has said that the first four months of 2015 has set a new record in total vehicle miles in the US – up nearly 32 billion since the previous high in 2007, pushing gas consumption as well as prices upward. Lower gasoline prices and a recovering economy (consumer spending in May, 2015 had the highest month jump in six years) are two reasons for the jump, probably augmented by the continuing lack of viable alternatives to car driving for many people. But a four-month blip is not enough to explain years of delays.
We do know some things that are contributing to the larger problem – land use patterns and population growth are the most important. The low-rise dense designs that make older urban areas walkable and transit-efficient is illegal to build in many places today due to parking requirements, anti-mixed use and other zoning requirements, etc.
We know some things that may appear to be causative but actually aren’t – making roads safer for pedestrians and bicyclists, prioritizing bus and trolley traffic, even reducing the average speed of cars.
We know some things that (counterintuitively) do not help reduce congestion – most notably building more roads or adding lanes, all of which eventually fill up as our additional drivers decide to move into the new space.
And we know some things that do improve the situation, but usually only when they are applied as a group rather than singularly – improving road use efficiency using technology (signal timing, access controls, central monitoring) and other methods (car pools, HOV lanes, car sharing, perhaps driverless cars), increasing alternative options (transit both regional and downtown, bicycling), changing land-use patterns (Smart-Growth style transit-orientated development), requiring corporate and municipal Transportation Demand Management programs (incentives to not drive alone or to not drive at all), and (most effective of all) congestion pricing of various kinds.
What is needed is the cultural and political willingness to accept this knowledge and act upon it – while also coming to grips with the reality that the continuing imbalance of potential drivers to current or any plausible future amounts of road space means that congestion is a permanent part of a car-based reality.

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.
