AMERICAN UN-TRANSPORTATION
OF CARS-ONLY MUST CHANGE TO INCLUDE WALKING, BICYCLING AND PUBLIC TRANSIT
Americans
know first hand cars still dominate urban transportation—and anyone who travels
to other advanced nations, particularly Western Europe, experiences what our
transportation system could offer—sensible and safe walking, bicycling and
public transportation along with supporting infrastructure for each mode.
While
ten percent of urban trips here are walking (nine percent) and bicycling (one
percent), European urban trip shares typically amount to double digits for each
non-car mode. Public transit share of
urban trips here? Just three
percent. Even Canada with similar
walking and bicycling shares reaches 13 percent public transit share and almost
double the U.S. total of walking, bicycling and public transit share of urban
trips of 13 percent. America today truly
presents a picture of un-transportation.
The
solution to the urban U.S. un-transportation can, thankfully, follow the
discoveries and applications of treatments now decades old in Europe. Europe always did have an excellent rail
passenger train network now featuring a new plateau of service provided by high
speed rail lines which criss-cross the continent and extend to the British Isles
through the Chunnel. (The Europeans
actually copied the first major high speed rail line, built in Japan, which has
yet to experience a single fatality in more than a half century of operation.)
There
exist three major walking and bicycling innovations in Europe which provide
both mobility and safety even on busy streets and thoroughfares. For street sections sidewalks remain the key
to the walking mode. But for bicycles
the invention of the cycle track—bicycle lanes protected from parked vehicles
and travel lanes by curbs, cones or planters—provide an equality of the bicycle
enjoyed by only cars and walkers in the past.
Cycle tracks emerged towards the end of the last century as a solution
to the growth of car travel in Europe which caused ever increasing fatalities
to bicyclists and in many cases crowding the bicycle off busy streets
altogether. (The story of cycle track in
the Netherlands at UTube http://www.youtube.com/watch?v=XuBdf9jYj7o provides an excellent history of cycle track
emergence and applications.)
The
second innovation dates from 1966 in the U.K.—the modern roundabout. With over 3,000 roundabouts in the U.S. and
Canada now this intersection device performs magic—it cuts serious injuries and
fatalities upwards of 90 percent, reduces delay for all users and cuts both
gasoline consumption and pollutants by sizeable amounts. While walkers and car occupant injury studies
found indisputable benefits for both, bicyclist safety impacts were mixed. For bicyclists smaller roundabouts do provide
a modest safety gain—and now on/off ramps are being introduced, a treatment
aimed at less expert bicyclists.
Further, the provision of a separate bicycle path or multi-use path at
intersections assures a definite increment of safety for bicyclists at single
lane roundabouts and likely one at multi-lane roundabouts. A pathway for bicyclists at roundabouts needs
to become standard practice. For
bicyclists, cycle track along street segments combined with roundabouts with a
separated pathway present an infrastructure improvement unlocking the bicycling
mode in urban America.
The
overall category “traffic calming” represents the third innovation in bicycling
and walking infrastructure, again a set of evolving treatments first developed
in Europe and quickly adopted in the United States starting in the 1990s with
the first emphasis here their use on
local streets. Speed
humps/tables/bumps, bulb-outs, median diverters, and also roundabouts are just
examples of literally dozens of traffic calming designs. Speed constraints on traffic provide a safer
and more comfortable environment for walking and bicycling. Traffic calming provides that
environment. For example, vehicle
yielding to walkers reaches 100% when speeds at intersections are in the range
of 0-10 mph. The safest environment for
walking and bicycling—again, a European innovation—is “shared space” where a
number of traffic calming treatments are applied in a defined area where
walkers and bicyclists retain the right of way over vehicles.
The
three innovations—cycle track, roundabouts and traffic calming—apply to the
walking and bicycling modes. But
efficient and effective public transit depends on a walkable, bikable
community. U.S. urban designer Peter
Calthorpe emphasizes a walkable community must be in place for successful
public transportation services.
Making
a transportation system in the United States means investing heavily for the
first time in the infrastructure for walking and bicycling at a rate of tens of
billions of dollars yearly for a decade or so—that is just the federal level of
funding required. That level of funding
leads to lower support costs for existing public transportation but also a much
greater demand for new public transportation routes and services, particularly commuter
rail and light rail.
The
payoff for these investments is clear.
First these investments promise reduced injury and fatality rates for
all modes. Car dependency declines
along with associated urban congestion, improved air quality, and reduced
energy consumption. Health benefits from
more walking and bicycling occur. And
perhaps most important, higher levels of urban density arise which in turn
reduces car travel and fosters greater use of public transportation and the
“active modes” of walking and bicycling.
The American economy benefits from the presence of an efficient transportation
system and the disappearance of our current urban carcentric
“un-transportation.”
