How would you solve the issues that traffic congestion bring such as air pollution, noise pollution and delayed traffic. These are obvious characteristics which define traffic congestion, however when looking at the problem in some context (Barcelona) and in more detail we see other issues which arise as reported in the Guardian:
“A study from the local Environmental Epidemiology Agency determined that 1,200 deaths could be prevented in the city yearly just by reaching EU-mandated levels for nitrogen dioxide levels (this would mean a five-month rise in life expectancy). Add to that an estimated 18,700 fewer asthma attacks, 12,100 fewer cases of acute bronchitis and 600 fewer cardiovascular-related hospitalisations, and the problem becomes apparent for a city with a population of 1.6 million. Traffic is also the first cause for noise pollution in the city; 61% of its residents live with noise levels higher than those deemed healthy by legislation… The city has only 6.6 sq metres of green space per inhabitant (with the figures standing at just 1.85 in Eixample and 3.15 in Gràcia), closer to Tokyo’s three than to London’s 27, or Amsterdam’s staggering 87.5. The World Health Organisation suggests every city should have at least 9 sq metres per capita.”. So how does Barcelona propose to solve these said issues?
