People love statistics. They let us understanding the world
beyond our own senses. USA Today
publishes a daily Snapshot
which presents a graph of random statistics. Sports talk and business analysis
are dominated by statistics. We measure our progress, or lack thereof, and
compare ourselves with others, based on statistics about our size, activities and accomplishments.

Planners strive to anticipate future needs, which sometimes creates self-fulfilling prophecies: by preparing for a situation we help cause it. This
is particularly true of automobile
dependency. Planning decisions intended to accommodate automobile travel
can create a cycle of increased vehicle travel, more automobile-oriented planning, and reduced alternatives. This concept is conveyed brilliantly in the cartoon below, drawn
by transportation engineer Ian Lockwood and published in the March 2012 ITE Journal.

Our profession relies on logical analysis of accurate data.
There are an amazing number of ways to go wrong.

I write this column (2 February) the U.S. House Transportation Committee is debating changes
in H.R. 3864, the American Energy and Infrastructure Jobs
Act, which will determine future federal transportation policy.

I am sorry to report that, Canada, my chosen country (I immigrated here in 1993), recently withdrew from the Kyoto Accord, which sets international climate change emission reduction targets.
It’s worth noting that this decision was made by the ruling Conservative Party which received less than 40% of total votes, but the other four parties split the
more progressive votes and are unable to form a coalition, resulting in federal policies that are far more politically conservative than the average Canadian

Bad planning simply extrapolates past trends:
“We experienced 2% annual growth during the last decade, so we’ll assume that
will continue into the future.” Good planning attempts to understand underlying factors
that affect change. Such is the case with the price elasticity of vehicle
travel, that is, the changes in vehicle travel caused by a change in transport
prices (fuel, parking, tolls, insurance, etc.).

An important current policy debate concerns whether the next U.S. federal
surface transportation reauthorization should require spending on
“enhancements,” which finance projects such as walkways, bike paths, highway landscaping and historic preservation. This issue
receives considerable attention, despite the fact that enhancements represent less
than 2% of total federal surface transportation expenditures, because it raises
questions about future transport priorities, particularly the role of walking and cycling. In other words, should non-motorized modes be considered real transportation.

Let me tell you
a scary story that you can use to frighten fellow planners at next week’s
Halloween party. It’s not just fun and games – this story is true and may

Once again the Texas Transportation Institute (TTI) published its annual Urban Mobility Report (UMR), and once again I feel obliged to warn planners that it is based on faulty assumptions and biased analysis methods. This is not to deny that traffic congestion is a significant problem, but the UMR significantly exaggerates its importance compared with other transport costs and exaggerates roadway expansion benefits.
