Europe and North America's most congested cities

 

London and Los Angeles among the worst places to drive... but Milan takes the top spot

  • Milan, Italy, shown to have the worst traffic congestion across all European and North American major cities
  • Londoners spend an incredible average of 83.4 hours in traffic each year trying to commute across town
  • Study authors claim congestion acted like a 'magnet' - where it existed, more traffic was disproportionately attracted

Milan has the worst traffic congestion of any city across Europe and North America, new data shows.

Although London and Los Angeles remain frighteningly bad for congestion and are among the top 10 worst offenders, Milan, Italy, took top spot.

Traffic data organisation INRIX used archived data to create a ranking of the worst cities and countries for traffic congestion.

It also as detailed the average number of hours spent waiting in traffic at each centre.

Drivers in London waste a staggering 83.4 hours a year in traffic - the worst of the top 25 cities.

Those in Los Angeles waste a slightly less shocking 64.3.

Drivers in Milan - the city ranked overall as the worst - only lose 57 hours a year.

INRIX used a detailed formula to produce its data that involved comparing a 'free flowing' speed on a particular segment of road to real time traffic speeds taken during peak hours.

Wasted driving minutes were created by placing wasted minutes in traffic against estimated typical trip lengths and the average number of trips taken each year.

In its findings, INRIX said after seven years of only 'modest' congestion, its 2013 report showed it was the same offenders topping the list.

'Simply put, it appears that congestion acted like a magnet - where it existed, it had a tendency to attract disproportionately more of it.

'Traffic is back on the rise in 2013, even in countries showing continued declines. Traffic congestion was up in six of the 15 countries analyzed: the U.S., UK, Ireland, Switzerland, Luxembourg and Italy.'

And it is not good news for European drivers, with traffic congestion rising for the first time in two years.

'With traffic congestion increasing at 3 times the rate of employment, 10‐day long traffic jams like we've seen in China and the 2-3 hour daily commutes that are part of daily life for people in Sao Paolo, Brazil, today could become the reality for drivers in Europe and North America in the not so distant future.'

The Queen's London residence is exposed to the highest levels of air pollution in the country, figures reveal today.

Traffic traveling along the A302 - known as Grosvenor Place - which runs adjacent to Buckingham Palace, produced the highest levels of toxic gas nitrogen dioxide (NO2) in 2012, data shows.

Figures from the Department for Environment, Food and Rural Affairs show the average level of the gas - produced mainly from diesel engine traffic fumes - was 152 micrograms per cubic metres of air.

The figure is almost four times the European legal limit of 40 micrograms per cubic metre.

Lower Grosvenor Place, another road close to the Palace, registered as 109 micrograms per cubic metre.

Other highly polluted areas include Oxford Street near Marble Arch, which registered at 150 micrograms and Cockspur Street near Trafalgar Square on 138 micrograms.

The fourth and fifth locations were Park Lane and Knightsbridge - which measured 135 and 134 micrograms respectively.

Roads near other top London tourist attractions such as Madam Tussauds, Hamleys Toy Shop and  Covent Garden also featured on the list of 50 worst offenders - ALL of which were in London.

Almost 30,000 people die every year due to respiratory problems caused by air pollution. Nitrogen dioxide in particular has been linked to breathing issues.

Today environmental groups criticised the statistics.

Simon Birkett, Founder and Director of Clean Air in London, said: 'These levels of nitrogen dioxide (NO2) are nothing short of staggering.

'The World Health Organisation guideline is no human exposure in a single hour over 200 micrograms per cubic metre (with an annual average guideline of 40).

'The thought that hundreds of thousands or millions of tourists and Londoners in a year may be exposed to air pollution this high is deeply troubling.

'In London, we need the Mayor to: ban the oldest cars emitting carcinogenic diesel exhaust as Berlin did more than four years ago, remove the turning circle requirement that still forces cabbies to choose between two large diesel taxis if they want a new vehicle and reinstate Phase 5 of the low emission zone that was a key commitment in the Mayor’s Air Quality Strategy until scrapped early last year.

'He also needs to ensure his ultra-low emission zone for 2020 includes the roads with the highest NO2 rather than excluding them which will force the most-polluting vehicles to join those avoiding the congestion charging zone and issue smog warnings to save lives, avoid hospitalisations and build public understanding of air pollution.

Cockspur Street had the third highest levels of N02 at 138 micrograms

'In short, ‘invisible’ air pollution is where smoking was 30 years ago in terms of the known health risks and the lack of public awareness.  People need Prince Charles to champion action to comply with air pollution laws in London and elsewhere.'

The UK faces fines of up to £300m from the European commission after they launched legal action due to a failure to reduce high levels of NO2 air pollution from traffic.

The commission said this was despite over a decade of warnings and several extensions and postponements given to the British government.

Other European countries have also failed to meet the air quality directive, the commission said.

A Defra spokesman said: 'Air quality has improved significantly in recent decades. Just like for other Member States, meeting the NO2 limit values alongside busy roads has been a challenge.

'That is why we are investing heavily in transport measures to improve air quality around busy roads and we are working with the Commission to ensure this happens as soon as possible.'

The highlighted that the UK meets the EU air quality limit values for all other air pollutants.

Responding to the latest figures, a spokesman for Boris Johnson said: London’s air quality is steadily improving, meeting legal limits for eight out of nine EU regulated pollutants.

'Since the Mayor was elected NO2 emissions have reduced by 20 per cent and the number of people living in areas exceeding NO2 limits has halved but he fully recognises the need to take further action.

'This includes the introduction of the world's first Ultra-Low Emission Zone in central London from 2020, tougher requirements for taxis from 2018 and a £20million fund to tackle local problem areas.

'These most ambitious measures will deliver enormous economic and environmental benefits for central London and will make this global city an even better place to live, work and visit.'

Air pollution killed about seven million people in 2012, making it the world's single biggest environmental health risk, the World Health Organisation (WHO) says.

The toll, a doubling of previous estimates, means one in eight of all global deaths in 2012 were linked to polluted air.

This means air pollution has overtaken poor diet, high blood pressure and tobacco smoke as the leading cause of preventable death worldwide.

It also shows how reducing pollution inside and outside of people's homes could save millions of lives in future, the United Nations health agency said.

Air pollution deaths are most commonly from heart disease, strokes or lung disease.

It is also linked to deaths from lung cancer and acute respiratory infections.

‘The evidence signals the need for concerted action to clean up the air we all breathe,’ said Maria Neira, head of the WHO's environmental and social public health department.

‘The risks from air pollution are now far greater than previously thought or understood, particularly for heart disease and strokes.’

Poor and middle-income countries in Southeast Asia and the Western Pacific region had the largest number of air pollution-related deaths in 2012, with 3.3 million deaths linked to indoor air pollution and 2.6 million deaths to outdoor air pollution.

Air pollution has overtaken high blood pressure, poor diet and smoking as the world's leading cause of preventable death

Indoor pollution is mostly caused by cooking over coal, wood and biomass stoves.

The WHO estimates that around 2.9 billion people worldwide live in homes using wood, coal or dung as their primary cooking fuel.

Flavia Bustreo, a WHO family health expert, said women and children - especially those living in poor countries - often bear the brunt of the risks from indoor pollution ‘since they spend more time at home breathing in smoke and soot from leaky coal and wood cooking stoves’.

Outdoors, air is mainly polluted by transport, power generation, industrial and agricultural emissions and residential heating and cooking.

Research suggests outdoor air pollution exposure levels have risen significantly in some parts of the world, particularly in countries with large populations going through rapid industrialisation, such as China and India.

The WHO's cancer research agency IARC published a report last year warning that the air we breathe is laced with cancer-causing substances and should be officially classified as carcinogenic to humans.

Carlos Dora, a WHO public health expert, called on governments and health agencies to act on the evidence and devise policies to reduce air pollution, which in turn would improve health and reduce humans' impact on climate change

‘Excessive air pollution is often a by-product of unsustainable policies in sectors such as transport, energy, waste management and industry,’ he said.

‘In most cases, healthier strategies will also be more economical in the long term due to healthcare cost savings as well as climate gains.’

 

     

 

 

 

 

 

 

 

Shopping on London’s bustling Oxford Street may be bad for your bank balance.

But now there is evidence that it is detrimental to your health too, as it has been shown to have the highest levels of toxic air in the world.

A scientist has revealed that the busy stretch of shops has the highest levels of nitrogen dioxide (NO2), which is produced by diesel fumes and can trigger asthma and heart attacks.

WHY ARE NITROGEN DIOXIDE LEVELS SO HIGH ON OXFORD ST?
  • The street is at the centre of a city that is a large source of NO2, experts at Kings College said.
  • It is dominated by diesel vehicles such as buses and taxis and has among the highest flow of buses anywhere in the UK.
  • A large number of the buses use technology that deliberately produce increased emissions of NO2
  • Scientists describe Oxford Street as ‘a street canyon’ which maximises the concentration of the gas because is its enclosed and poorly ventilated.

The chemical irritates the lining of the lungs and leaves healthy people more susceptible to lung infections. Noticeable symptoms include wheezing, coughing, colds, flu, and bronchitis.

David Carslaw, of King’s College London, told The Sunday Times that he has recorded peak levels of 463 micrograms of nitrogen dioxide per cubic metre of air, which is over three times higher than the average amount of the pollutant since the start of the year.

He told the newspaper: 'To my knowledge, this [level] is the highest in the world in terms of both hourly and annual mean. NO2 concentrations [in Oxford Street] are as high as they ever have been in the long history of air pollution.'

Even at the average, 135 milligrams per cubic metre, the nitrogen dioxide levels are three times higher than the EU’s safety limit.

The street broke hourly limits of 200 milligrams per cubic metre more than 1,500 times during the year.

Dr Carslaw told MailOnline 'This [Oxford Street] is easily the highest annual mean NO2 concentration in Europe.'

Delhi and Mumbai, which are frequently pictured with smoggy skies, have average levels of NO2 at 62 micrograms per cubic metre in comparison.

In February, figures from the Department for Environment, Food and Rural Affairs claimed that traffic travelling along the A302 - known as Grosvenor Place - which runs adjacent to Buckingham Palace, produced the highest levels of the toxic gas at an average of 152 micrograms per cubic metre of air in 2012.

The study also found that Oxford Street was highly polluted, registering at an average of 150 micrograms near Marble Arch, while Trafalgar Square has an average of 138 micrograms of nitrogen dioxide per cubic metre of air.

Park Lane, Knightsbridge and Covent Garden were all found to have seriously high levels of the pollutant.

Bosses from the collection of shops down London’s most famous high street are calling on Mayor Boris Johnson to reduce the number of buses that crawl down Oxford Street.

Richard Dickinson, chief executive of New West End Company which represents traders in Oxford Street, told The Independent: ‘We are working closely with the relevant London authorities to look at longer term traffic reduction initiatives and we are keen to see ideas rapidly put in place. Businesses in the West End want action.’

City Hall said that it has already reduced the number of buses by a fifth, while hybrid engines on London’s famous double decker’s are set to cut the pollution problem.

Almost 30,000 people die every year due to respiratory problems caused by air pollution and nitrogen dioxide in particular has been linked to breathing issues.

Alpine tourist meccas which attract thousands of British tourist every year are among the most polluted in France, new research reveals.

It shows that Annecy, the beautiful waterside town surrounded by ski slopes, has the second worst air quality in the whole of France.

Despite claiming to have ‘Europe’s cleanest lake’, the World Health Organisation (WHO) survey shows its air is full of dangerous fine particles.

Annemasse, another French town surrounded by dramatic mountainous countryside on the Swiss border, is similarly blighted.

The WHO researchers looked at pollution levels in nearly 1,600 cities in 91 countries for the years 2008-2013.

Annecy, which is second on the ‘most polluted air’ list for France, has an average 25 microgrammes of so called PM 2.5s - the most dangerous fine particles.

They pose a particularly dangerous risk to anyone with breathing conditions including asthma, but also adversely affect everybody else.

The reason for the high level of pollution is the cold, dry, Alpine air which traps pollution close to the ground, and stop it being carried away by the wind.

However the region is still far behind Delhi, the most polluted city on Earth, which has six times more harmful particles in the air than European cities

The urban sprawl of Geneva is close to Annecy, and there is always masses of traffic carrying people and goods up to the Alpine towns and villages.

The most polluted French city on the list was Douai, in northern France, which had 26 microgrammes of fine, harmful particles per units of air.

Delhi, the most polluted city in the world, had 153 micrograms per cubic metre of the most harmful particles - making it some six times more polluted than the worst cities in Europe.

Beijing officials this week warned children and the elderly to stay indoors due severe smog.

It has become a major problem in China's capital city and elsewhere in the country - forcing closures, damaging health and reducing visibility to less than 10 metres.

The solution, according to Dutch designer Daan Roosegaarde, is to use an electronic vacuum cleaner to clean up the air.

‘If you apply that to smog, to create fields of static electricity of ions, which literally attract or magnetise the smog so it drops down so you can clean it, like an electronic vacuum cleaner.’

SMOG VACUUM: HOW IT WORKS

By making a weak electromagnetic field (similar like static electricity that attracts your hair) the smog components in the air are pulled down to the ground where they can be cleaned.

This creates gigantic holes of clean air in the sky, which can be as large as 60 metres, according to Roosegaarde.

The Chinese government has announced plans over the years to tackle the pollution problem but has made little apparent progress

Meanwhile, visibility shrank and small-particle pollution soared to a record 40 times higher than an international safety standard in one Chinese city as the region entered its high-smog season.

Winter typically brings the worst air pollution to northern China because of a combination of weather conditions and an increase in the burning of coal for homes and municipal heating systems.

For the large northern city of Harbin, the city's heating systems kicked in on Sunday, and on Monday visibility there was less than 50 yards, according to state media.

It is one of the greenest national capitals in the world. Its metro transit system caters to around 23 lakh passengers daily and government buses are running on clean CNG. But Delhi continues to remain the country's most-polluted city.

A study funded by the Ministry of Science & Technology has identified the metropolis as a "high health risk" zone, stating there is an alarming rise in the level of outdoor particulate matters (PM) in the city.

"The pollution in Delhi has increased by 21 per cent in the last 10 years and is persistent. For more than 50 per cent of the day, the pollution is high in the city and is sustaining for long periods. This is posing a major health risk to its people," said Dr Sagnik Dey, assistant professor, Centre for Atmospheric Sciences, IIT Delhi, who led the research team.

Delhi retains 'most polluted city' crown as study brands it a 'high health risk zone'

"Humans, if exposed to particulate matter for a long time, are at a high risk of respiratory and heart diseases," he said.

As cities such as Meerut, Kanpur, Agra, Patna, Kolkata and Mumbai are also facing rising levels of air pollution, the researchers have called for generating a national health database and carrying out cohort studies at both urban and rural hotspots to know the level of toxicity in humans.

The researchers have presented the 10-year statistics of the spatial patterns of outdoor particulate matters having a diameter of 2.5 micrometres (PM 2.5) in the subcontinent for the first time based on the satellite data.

Particulate matters (PM) are materials suspended in the air in the form of minute solid particles or liquid droplets and are considered as atmospheric pollutants. They can adversely affect human health and also have impacts on climate and precipitation.

 

Scientific study Scientists from IIT Delhi, IIT Kanpur, University of Illinois, US and Dalhousie University, Canada have participated in the research and done a comprehensive study with remote sensing and identified five hotspots in high-risk zone.

The five hotspots where PM2.5 increases by less than 15 microgram m3 over the 10-year period have been identified. They cover parts of the eleven states - Punjab, Haryana, Delhi, Uttar Pradesh, Bihar, West Bengal, Orissa, Chhattigarh, Gujarat, Maharashtra and Andhra Pradesh - and Bangladesh, said Dey.

"The analysis showed that that 51 per cent of the subcontinent's 1.4 billion people are exposed to pollution that exceed the World Health Organisation's (WHO) highest annual air quality threshold of 35 microgram m3," he said.
