Traffic congestion in Oxford is a public health issue. It increases air pollution, lowering air quality breathed, which is a known cause of asthma, lung cancer and cardiovascular diseases. It increases the risk of traffic accidents through poor driver behaviour and judgement. Stuck in a traffic jam last week in Oxford, brought about through traffic control system failures, this driver experienced first-hand both air pollution and road safety issues. Globally, road traffic accidents cause 1.25 million deaths per year, with the highest road traffic fatality rates in low-income countries.
