Dear Megan
Request made under the Official Information Act 1982
Thank you for your email of 11 May 2019 to the Ministry of Transport requesting the following
information under the Official Information Act 1982 (the Act):
‘What data do you hold on the number of motor vehicles using Cobham Driver? I would
like to know all holdings for the period from 1 January 2018 to the present.
I am interested in the number of motor vehicles using that road and their average
speed, preferably per minute, alternatively per hour, during peak hours or per day or
per week or per month.
If you do not have the data for that road what is the nearest road you do have data for
over this time period?
Are you able to differentiate the types of vehicles e.g. by axle length or RF technology?’
Your request was transferred to the NZ Transport Agency on 13 May 2019 for reply.
I have enclosed the fol owing documents that are within the scope of your request:
