The delays, which equate to 15 minutes for every 100 miles travelled, are largely due to the increase in vehicles on the road, thus creating more congestion.
Based on figures back in 2011-12, this represents an increase in delays by a third, while the report also stated that 89.7 billion miles were driven on the motorways and ‘A’ roads over the last year - up five billion over the past four years. Despite only accounting for two per cent of roads within the UK, motorways and ‘A’ roads carry a third of all traffic. The increased usage has also slowed the average speed on these roads, with vehicles now travelling at 59.3mph compared to 61.3mph four years ago.
The review stated Highways England have made progress towards their £15 billion investment in the network by 2020-21, but that targets will be difficult to achieve based on traffic growth. However, Highways England beat its targets for maintaining network availability, clearing motorway incidents and maintaining road surface quality.
The number of serious injuries caused on roads dropped by 4.9 per cent from 2014 to 2015, also leading to the number of fatalities and seriously injured dropping by 3.6 per cent. Another important target Highways England failed to meet was the user satisfaction rate with only 89.3 per cent of users saying they were “fairly or very satisfied” with the network, falling 0.7 per cent short of the desired 90 per cent target.
