ViaStrada was engaged by ARTA to develop a tool to convert short-term manual cycle counts to "annual average daily traffic" (AADT) estimates of cycle traffic. The methodology used standard pneumatic traffic counters with softer than normal rubber road tubes for detecting cycles.
Cycle traffic was counted at five sites around Auckland, with counts undertaken continuously for up to two weeks. In addition, manual counts commissioned by ARTA and undertaken by Gravitas during March 2007 were used to verify the reliability of the automatic counts and to help develop the tool.
MWH New Zealand Ltd (Christchurch) assisted with automatic counter data collection and data analysis of both the manual and automatic counts.
