TomTom Announces The Most Congested Cities in The UK

New figures released by TomTom shows that Oxford has seen the biggest traffic congestion increase across the UK, having risen from sixth to third place in a nationwide congestion ranking.

TomTom measured the top 50 most congested areas throughout Britain over the last six months. While congestion is worst in big cities, Oxford saw the biggest increase of 2.2% since March 2011.

The second biggest increase in congestion was seen by Belfast, followed by Bolton, Southampton and Sheffield.

Edinburgh, Glasgow and Aberdeen all place in the top 10 cities which have seen the biggest traffic jam increase in the past six months.

It is estimated that road congestion costs the UK economy £20 billion a year in lost production. If an estimated five per cent reduction in travel time for all business travel on the roads could be achieved, around £2.5 billion could be saved by reducing missed appointments and speeding up delivery times.

The research marks the launch of the not-for-profit TomTom International Traffic Foundation, that will bring together key stakeholders from academia, industry and policy making in order to collaborate on traffic congestion reduction.

It will fund PhD and post-doctorate research, publish research papers and host traffic management seminars.

TomTom's research also shows that London is the most traffic congested city in the country, with 36% of roads significantly more congested during rush hours than off peak times.

Following London is Edinburgh, with a congestion rate of 33 per cent. Behind Oxford in fourth place is Belfast where 31 per cent of roads are classed as congested, followed by Bradford (30 per cent), Manchester (30 per cent) and Birmingham (28 per cent).

Northampton, Warwick and Chesterfield are amongst the least congested big towns and cities, with congestion rates of under 10 per cent.

OUt of the top fifty, only five have seen a fall in congestion during the past six months: Bedford, Colchester, Newport, York and Chester.

TomTom used its real travel time database for the basis of the research, which has collected more than four trillion speed measurements to date, with over a billion new measurements being added each day.

A TomTom spokesman said: "Many people may be surprised to find that places like Oxford, Belfast and Bolton have suffered big increases in levels of traffic congestion.

"If 10 per cent of drivers use a live navigation system such as TomTom HD Traffic which is updated every two minutes, there will be a 'collective effect' that will reduce journey times in congested areas for all drivers by up to five per cent."
