New research by Moneybarn has revealed the slowest cities to travel by car with London unsurprisingly topping the list. By producing a ranking of several different factors including average speed roads requiring maintenance average daily traffic flow and hours lost in congestion the research produced an overall score out of 10 for each city in the UK as well as countries around the world. London was the UK s slowest city due to low average speeds of a miserable 18mph and a loss of 69 hours in traffic every year. Ranking second was Derby mostly due to a high percentage of roads requiring maintenance (15%) - the city had by far the biggest percentage with roadworks causing havoc in the area. Bristol placed third with the second-highest amount of hours lost to congestion (37 hours) and an average speed of 18.3 - 0.3mph faster than London. At the other end of the spectrum the fastest cities to travel by car are Peterborough Darlington and Bedford with less than 2% of roads needing maintenance in all three cities and less than 20 hours lost to traffic each year. The research applied the same metrics globally to reveal that Peru is the slowest country in the world to travel by car with a journey taking 42% longer on average than it should. Colombia and the Philippines were in second and third place with the highest levels of 53% extra time stuck in traffic.
