Congested Corridors
Specific roadways contributed notably to congestion:
-
London: The westbound A40 between the North Circular and the A406 during the 5:00 PM peak hour resulted in an additional 17 minutes of travel time daily, totalling 68 hours annually.
-
Bristol: The eastbound A420 from the Lawrence Hill Roundabout to Hollow Road at 4:00 PM caused drivers to lose about 5 minutes daily, equating to 21 hours annually.
Contributing Factors
The report attributes London's persistent congestion to its dense population, employment opportunities, and economic activities. Additionally, roadworks, such as those at the M25 Wisely Interchange, have exacerbated traffic delays.
Mitigation Efforts
Transport for London remains committed to enhancing mobility by investing in sustainable transportation options, including walking, cycling, and public transit, to alleviate congestion.
In summary, the INRIX 2024 Global Traffic Scorecard underscores the ongoing challenges of traffic congestion in the UK, particularly in major urban areas, highlighting the need for continued investment in infrastructure and sustainable transportation solutions.
