Bicycles, Transit, and the Last Mile

Bike Oasis on the Portland Transit Mall

Transit agencies have a problem called the Last Mile.  It’s especially problematic in lower density communities, where convenient, high frequency local feeder bus, light rail, and trolley lines are unlikely to be economically viable.  Many US communities have this problem.  The most common solution is the Park-n-Ride — a gigantic surface lot or parking structure adjacent to a regional mass transit line.  People drive their cars a few of miles and park them all day — usually at very low cost to the driver, and often for free (though of course, parking isn’t actually free).  There are lots of problems with this model.  Parking lots take up a lot of space.  Structures are very expensive ($10k-$25k per parking spot).  What do you do when you get where you’re going?  If the transit line doesn’t come within easy walking distance (500 meters?) of your ultimate destination, this model probably isn’t attractive.  It also assumes that you’re going to own or have access to a car, even though you’re taking transit, which precludes you from reaping most of the economic benefits of not driving, as they only accrue when you get rid of the car completely.

I bring the Last Mile problem up because I just came across a study entitled Bicycling Access and Egress to Transit: Informing the Possibilities.  Combining bicycles and transit instead of cars and transit can help with a lot of the above issues.  The cost per bike parking space is at most a couple of hundred dollars, not $10,000 or more, and for a given area, you can park ten times as may bikes as cars, making a bicycle park-n-ride much more economical in both dollars and space.  It’s also possible to take at least a few bicycles along on transit vehicles, which can solve the problem of getting to one’s final destination on the other end, though not generally for everyone since bicycle capacity tends to be limited, especially on buses.

Location Efficiency and Housing Type

According to this EPA study, regardless of the type of housing, living in an area with good transit access saves more energy than building a “green home”. Of course, living in a mixed use, transit accessible apartment that’s also energy efficient uses the least energy, but it’s important to realize how limited the potential for cost-effective energy efficiency is in a sprawling suburban context.

Bicycle infrastructure progress along Goose Creek

I’ve been biking along the Goose Creek bike path a lot over the last few months.  Boulder Aikikai is out there, and so is Community Cycles, and I’ll go for a short triangular on the Boulder Creek path, 13th St. and Goose Creek when I just need to get out in the sun for a little while.  Throughout the summer I was repeatedly reminded that there’s no good way to get from the path up to the east side of 30th St, and crossing 30th kind of sucks, especially when there’s any traffic.  A couple of times I went so far as to go under it and the nearby railroad tracks, and then up into the parking lot, and back over the railroad tracks and through another parking lot.  I’m sure this involved trespassing.  And I wasn’t the only one doing it either, there was a trail worn in the grass and the gravel.

So I was stoked to hear that a ramp connecting Goose Creek to the east side of 30th was in the works, and this fall the heavy equipment came out and started making it a reality.  I’ve been taking pictures as it progresses:

Population Growth vs. Migration in Boulder and the World

The Boulder Blue Line has a short post entitled This Law Cannot Be Repealed by Albert Bartlett, who is an emeritus professor of Physics at CU, and who is most well known for speaking about the absurdity of “sustainable” growth and what exponential growth really means.  He’s also one of the original architects of Boulder’s “Blue Line”, which has limited growth beyond certain boundaries within the city and county.

I agree with Bartlett on a lot.  Unconstrained population growth is undoubtedly, in a global context, an epic disaster.  In his collection of essays Brave New World Revisited, Aldous Huxley noted of overpopulation that “Unsolved, that problem will render insoluble all our other problems.”  Similarly, the unconstrained geographic growth of towns and cities is a catastrophe, resulting in very low-density, car-dependent development which exacerbates the consequences of population growth by increasing the amount of resources that each individual consumes, in terms of land and energy and material goods.

Parks are for People

Urban density and good public space make scenes like this possible.

When do fuel costs actually matter?

Kim Stanley Robinson gave a fun talk at Google a couple of years ago in which he brought up the possibility of large, slow, wind powered live-aboard bulk freighters, among other ideas.  I was reminded of it by this post from Alex Steffen.  Especially for commodities like coal, grains and ore — non-perishable goods that get carried in bulk carriers — what matters is the net flux of materials and the predictability of supply.  More (or larger) slow ships can deliver the same flux as fewer high speed ones.  International contracts for these goods can span decades.  If fuel prices became a significant portion of their overall cost, it would be worthwhile to make this kind of ships-for-fuel substitution.  However, it turns out that fuel is a vanishingly small proportion of the overall cost of most internationally traded goods.

Containers

Our neighbors in Pasadena moved back to Thailand, and packed their entire household into a single half-sized shipping container.  The cost to get it from their home in SoCal to their home outside Bangkok was $2000.  Their combined airfare was probably a larger fraction of the cost of moving across the Pacific.  You can get a full-sized shipping container moved from point A to point B, anywhere within the global shipping network, for several thousand dollars.  If your cargo is worth significantly more than that, then you don’t have to worry about Peak Oil destroying your business.  For a typical container carrying $500,000 worth of goods, the shipping costs (not all of which are related to fuel!) represent about 1% of the final costs of the goods.  If fuel prices were to go up by a factor of ten, the shipping costs would still only represent 10% of the overall cost.  This would have an effect on business, to be sure, but it would not cause global trade to collapse.

Goss-Grove neighborhood to be re-zoned for lower density

The Goss-Grove Neighborhood is slated to be re-zoned for lower density (PDF) as part of the Boulder Valley Comprehensive Plan update.  Goss-Grove is right in the very core of Boulder, next to downtown and CU, intrinsically walkable and bikeable.  It should be dense!  Residents are unhappy with the low-quality student slumlord apartments.  Small, affordable, high quality condos that blend in with 100 year old homes could increase density, without destroying the neighborhood’s feel.  Vancouver, BC has done this well.

Understanding the Republican Party’s Reluctance to Invest in Transit Infrastructure

A great look at the geography behind the Republican demonization of mass transit.  To a large degree in the US cities are democratic and the exurbs and hinterlands are republican.  Since so much of our transportation funding gets funneled through the federal government, this means cites spend a lot of time getting screwed.  Policy decentralization would help a lot.

Sprawl at the Gates

Boulder County is slowly being invaded from the southeast and it’s not clear what we can do about it.  Sprawling development is (still) the order of the day in Broomfield, Weld, and Jefferson Counties, and it looks set to generate a lot more trips through Boulder County in the coming decades.  Personally, I’m praying for $8 gasoline.
