In the worst of the peak, traffic delays cost Aucklanders an average of 40 minutes for each hour driven. The worst times to travel in Auckland are Tuesday morning and Wednesday afternoon, with congestion rising to over 78 per cent when compared to non-peak times. Commuters travelling in peak hour traffic have the best run on either a Friday morning or a Monday evening where congestion levels are lower at 65%.
The TomTom congestion index shows that the most congested day in Christchurch in 2012 was on the 6th June, coinciding with the heaviest snow fall recorded for the season.
Wellington was found to be the least congested city of those surveyed in New Zealand, with a congestion rating of 24 per cent. Friday afternoon was the quietest time on the road and congestion levels were markedly lower across the board.
“The TomTom congestion index shows relative congestion in key cities across the world. At TomTom we’re constantly working to help governments and road authorities make more informed decisions about tackling the issue of traffic congestion and the Index aims to do just that,” said Chris Kearney, Vice President TomTom Asia Pacific.
“TomTom’s world-class traffic information also helps drivers get to their destinations faster. Significantly, when used on a large scale, TomTom HD Traffic has the potential to ease traffic congestion in cities and urban areas by routing drivers away from traffic hot spots,” said Kearney.
TomTom’s Congestion Index is the world’s most accurate barometer of congestion in urban areas. The Index is uniquely based on real travel time data captured by vehicles driving the entire road network. TomTom’s traffic database contains over six trillion data measurements and is growing by five billion measurements every day.
The methodology used in the Congestion Index compares measured travel times during non-congested periods (free flow) with travel times in peak hours. The difference is expressed as a percentage increase in travel time. The Index takes into account local roads, arterials, as well as highways. All data is based on actual GPS based measurements.
As well as assigning and ranking the overall congestion levels of over 161 cities around the world, the report analyses the congestion levels in cities at different times of the day and on different days of the week. TomTom analysed capital cities as well as cities with a population of over 800,000. In addition, a selection of key cities with smaller populations was included based on their regional importance to the transportation network.
