An occasional update on items from Motordom – the world of auto dominance
EVIDENCE OF THE SELF-EVIDENT
Jason Vanderhill picked this up from boingoing: “You can reduce highway lanes without making traffic worse.”
You cannot reduce traffic jams by building more lanes — in fact, more lanes often create more traffic. But new studies show that reducing roads doesn’t make traffic worse. … At Wired, Adam Mann goes on to explain that there are limits and caveats to this trick, but that, despite this, it does remain a great example of how what actually happens in the real world does not necessarily conform to our “common sense” expectations of what should happen in the real world.
Eric Britton of World Streets posts this summary surrounding ‘peak car’ – “a hypothesis that per capita car use is close to its maximum level, and may stabilise or turn down.” A roundtable discussion on the topic took place in London on 20 May 2014, available here.
• There have been strongly divergent trends in different locations ….
• At the aggregate level, evidence of shifts in demand predates recent economic difficulties, including decoupling of traffic growth and economic growth, reductions in propensity to learn to drive, changing land use and migration trends (which had previously been dominated by movements to areas encouraging higher car use, and in the 2000s reversed), growth of internet use, and decline in traffic levels in London and some other urban areas. These shifts have mostly been observed in the 1990s and early 2000s, including periods of strong economic growth.
• Over the same period, there have been changes in transport policy and travel conditions favouring public transport, walking and cycling in some places, changes in tax effects on prices (especially company car use), parking control, congestion levels, and fuel prices. ..
Taken together, these features would imply that per capita car use is influenced by both economic and other structural factors, cannot be converted to total traffic levels simply by multiplying by population, and demands serious re-examination. …

THIS VIDEO IS EARNEST AND INFORMATIVE.
You should watch it.
So not the most enticing come-on. But it’s true: this video has a good storyline about parking – the shaper of our cities – and good graphics too – “A new production from Streetfilms and transportation nonprofit ITDP breaks it down Schoolhouse Rock-style:”
