Moscow is world’s most gridlocked city, says Inrix

Moscow is the most gridlocked city in the world, according to a survey of snarl-ups by Inrix. The company’s annual Global Traffic Scorecard found that road users in the Russian capital lost 210 hours last year because of congestion. Inrix weights the data for population, and found that the next four cities on the congestion roll-call were Istanbul, Turkey; Bogota, Colombia; Mexico City; and São Paulo, Brazil. Brazil had another entry on this unwanted list, with Rio de Janeiro in seventh place. Russ

Moscow is the most gridlocked city in the world, according to a survey of snarl-ups by 163 Inrix.


The company’s annual Global Traffic Scorecard found that road users in the Russian capital lost 210 hours last year because of congestion.

Inrix weights the data for population, and found that the next four cities on the congestion roll-call were Istanbul, Turkey; Bogota, Colombia; Mexico City; and São Paulo, Brazil.

Brazil had another entry on this unwanted list, with Rio de Janeiro in seventh place. Russia’s St Petersburg came in ninth.

“The dominance of Latin American cities should not be a surprise due to their rapid urbanisation, high levels of informal settlements, unforgiving topographies and financial volatility,” Inrix suggests.

The top 10 was completed by London, UK (sixth); Boston, US (eighth); and Italian capital Rome (tenth).

Although not featuring in the top 10, Dublin, Ireland received its own dubious accolade: it has the slowest city centre speeds in the world, Inrix says, with an average of just 6mph during peak hours. This means it would almost be quicker to walk at certain times, and certainly makes cycling look like an attractive option for commuters.

Edinburgh and London tied for the title of UK’s slowest city, with last-mile speeds of 7mph.

    Plans to implement a clean air zone in London are premature, says a transport trade body - because zero-emission vehicles are not commercially viable. The Freight Transport Association (FTA) is unimpressed with the City of London Transport Strategy’s ambition to improve air quality and traffic in the east of the capital and the Barbican area by 2022. This draft scheme, which maps out a 25-year framework for managing streets within the City’s ‘Square Mile’, includes establishing a speed limit of 15 mp

    There is far more to working out the worth of a project than simply filling in a few headings on a spreadsheet. David Crawford surveys some recent thinking from the US and Canada. Cost benefit analysis (CBA) “can’t be carried out with a cookbook”, warns US analyst Professor Robert J Brent. “ You can’t just get out a spreadsheet and fill in the data for all the headings. Each transport CBA should have something that is distinctive, in terms of location (for example, for a rural area), types of user
