LONDON, Feb. 20, 2017 /PRNewswire/ -- INRIX today published its all-new Traffic Scorecard. Based on a new methodology, the analysis has increased to 1,064 cities across 38 countries, making this the largest ever study of congestion. The UK ranked as the 4^th most congested developed country in the world and the 3^rd most congested in Europe, with drivers spending an average of 32 hours a year in congestion during peak hours. For the first time, the INRIX Traffic Scorecard also includes the direct and indirect costs of congestion to all UK motorists, which amounted to £30.8 billion in 2016, an average of £968 per driver¹.

In the UK, the 2016 Traffic Scorecard analysed congestion in 87 cities and large urban areas. London remains the UK's most congested city, and ranks 2^nd in Europe after Moscow and 7^th in the world. Drivers in London spent an average of 73 hours in gridlock during peak hours. This contributed to congestion costing London drivers £1,911 each and the capital as a whole £6.2 billion from direct and indirect costs. Direct costs relate to the value of fuel and time wasted, and indirect costs relate to freighting and business fees from company vehicles idling in traffic, which are passed on to household bills through higher prices.  

Along with the capital, Manchester, Aberdeen, Birmingham and Edinburgh make up the UK's five most congested cities. Drivers in Manchester spent 39 hours in congestion during peak hours, and 10% of their total drive time (peak and non-peak hours) in gridlock, costing each driver £1,136 and the city £233 million. Motorists in Birmingham spent 9% of their total drive time in congestion last year, costing the city £407 million. Major cities in Scotland feature high-up in the UK ranking, with Aberdeen and Edinburgh placing 3^rd and 5^th respectively. The combined cost to both cities in 2016 was £363 million.

"Despite Brexit, 2016 saw the UK economy remaining stable, fuel prices staying low and employment growing to an 11-year high, all of which incentivizes road travel and helped increase congestion as the 2016 Traffic Scorecard demonstrates," said Graham Cookson, Chief Economist, INRIX. "The cost of this congestion is staggering, stripping the economy of billions, impacting businesses and costing consumers dearly. To tackle this problem, we must consider bold options such as remote working, wider use of road user charging and investment in big data to create more effective and intelligent transportation systems."

INRIX 2016 Traffic Scorecard Provides In-Depth City Congestion Analysis

New to the Traffic Scorecard is the ability to study congestion at different times of the day and across different parts of the road network, such as analysing traffic in city centres compared to vehicles coming in and out of a city, inside and outside of peak hours and at weekends. Insights for the UK include:

Overall (Peak & Non-Peak) Congestion Insights

• London is the worst city for congestion in the UK across both peak and non-peak hours with drivers spending an average of 13% of their total drive time stuck in traffic.
• Aberdeen is the second worst city across both peak and non-peak hours combined, with drivers spending 12% of their total drive time in gridlock.

City Centre Insights

• Peak hours in the centre of London is the worst time and place for drivers in the capital, where they spent an average of 23% of their time in congestion at an average speed of 4 mph.
• However, Exeter's city centre was the busiest to get around across all of the UK during peak hours, with drivers spending 25% of their time in congestion with an average speed of just 4.6 mph.
• Speeds fell by 80% (20 mph to 4.3 mph) in the centre of London during the day when congestion was at its worst, and by 83% (24 mph to 4 mph) in the evening during the worst periods.

In and Out of City Insights

• When getting in and out of London at peak hours, drivers achieved an average congested speed of 14.6 mph and spent 15% of their time in congestion.
• Aberdeen eclipses even London at peak hours and was the hardest city to get in to or out of with drivers stuck in gridlock for 24% of the time, moving at an average speed of 5.5 mph.

Business Impact 

• Business suffers the most from traffic in Cardiff with congestion between the morning and evening peak periods, both in and out and within the city, occurring for 15% of the time on average.
• Businesses moving about the centres of Exeter and London also suffer badly from congestion, sitting in traffic in the 'city centre' 17% and 16% of the time respectively during the day.

Weekend Insights

• Blackpool and London have the highest weekend congestion rates of 13% of drive time, but drivers cruise at their slowest in Brighton and Belfast where weekend congested speeds are just 4.3 mph.

Britain's Most Congested Roads

INRIX also identified the UK's most congested roads as well as the worst time to travel. London roads were busiest at evening rush-hour with the A406 Northbound from Chiswick Roundabout to Hanger Lane identified as the UK's most congested, where motorists spent 73 hours in congestion on this road in 2016. Outside of the capital, the A1 Southbound from College Gardens in Belfast was the most congested road, and the 6^th worst congested in the UK, with drivers each spending 49 hours in gridlock last year.

Notes to Editors

Data Sources
INRIX analysed 500 Terabytes of data from 300 million different sources covering over 5 million miles of road. The data used in the 2016 Traffic Scorecard is the congested or uncongested status of every segment of road for every minute of the day, as used by millions of drivers around the world that rely on INRIX-based traffic services.

Research Methodology
A new methodology was adopted for the 2016 Traffic Scorecard that calculates the percentage of time that drivers spent in congestion at different periods of the day/week and on different parts of a city's road network. This provides a more holistic view of a city's congestion problem. Cities were ranked by the peak hours that the average driver spent in congestion, the busiest part of the day when the most people are affected. Additional metrics are available online and in the full report.

¹An economic analysis was performed to estimate the total cost to the average driver in a city, and a total cost to the city population. This considered both the direct costs (those borne by the driver directly through wasted time and fuel) and the indirect costs (those borne indirectly through the increased costs to businesses which are passed on to households through higher prices). Worst corridors are limited to those that have the highest traffic volume and are ranked by the average hours of delay per driver in 2016.

The full report provides full details of the economic cost methodology.
