Traffic Congestion on the Rise in the UK, Top 10 Cities image

According to a report from TomTom a reduction of just five per cent in travel time for all business travel on the roads could generate around £2.5 billion of cost savings, by reducing missed appointments and speeding up delivery times.

However, this is not the case.

The new study shows that, perhaps unsurprisingly, London is the most traffic clogged city in the country, with 36 per cent of roads significantly more congested during rush-hours than at off-peak times.

Oxford has seen the biggest increase in traffic congestion of anywhere in the UK, according to new figures released today by TomTom.

At number two is Edinburgh with a congestion rate of 33 per cent, perhaps mainly due to road works linked to its ill-fated tram system.

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).
The least congested big towns or cities are Northampton, Warwick and Chesterfield, all with congestion rates of less than 10 per cent.

Only five in the top 50 have seen congestion fall over the past six months: Bedford, Colchester, Newport, York and Chester.

TomTom’s research is based on its real travel time database, which has collected more than four trillion speed measurements to date with over a billion new measurements added each day.
