The vehicle counter has not worked continuously in recent years hence Rodney District Council installed a back-up counter alongside the Department counter from December 2007 – Feb 2008. Both counters worked and reported no significant difference in vehicle count during this time. Vehicle count figures used in this analysis were taken from March 1st, 2007 – February 28th, 2008. Over the 365 days car count data was complete for 279 days. Data for the remaining 86 days was taken from either the previous week or the previous year (see appendix 2). A total of 87,214 cars were counted. The calibration figure of 4.3 visits per car count was used to calculate an estimate of 375,020 visits for the year.
