The study found drivers in both Auckland and Wellington faced fewer stop-starts than many large cities overseas, including Beijing (28,200, or 201 per cent more than Auckland), New York (15,480, or 65 per cent more) and Sydney (13,200, or 41 per cent more).
But surprisingly, drivers in both New Zealand cities faced more stop-starts than those in several larger cities - including Los Angeles (9000, or 3 per cent fewer than Auckland), Melbourne, Cape Town and Toronto. The worst city for stop-starts was Istanbul, Turkey, which had an average of 31,200 a year (233 per cent more than Auckland) while the best was Rotterdam, Netherlands, with an average of 6120 a year (35 per cent fewer than Auckland).
TomTom head of traffic Ralf-Peter Schafer said the results were fascinating. Castrol senior development technologist Gareth Bracchi said the project confirmed drivers were making lots of stop-starts in their vehicles. "In fact the numbers of stop-starts per year far exceeded our initial expectations - almost double in some cases."
