Why acquire and manage data?
! To know how the network is performing
! To guide investment and enhancement decisions
! To demonstrate how the network is delivering the desired community and Government outcomes
Bicycle and Pedestrian Data Issues! Currently, major barriers to
gathering better demand/usage data are cost and effort:
• Counts and surveys are labour-intensive
• Mechanical counting technology is more difficult to apply to bicycles and pedestrians than to motorised vehicles
• To date, little incentive for investment in bicycle & pedestrian counting technologies U.S. Department of Transportation, Bureau of Transportation Statistics, 2000, Bicycle
and Pedestrian Data: Sources, Needs, & Gaps, BTS00-02, Washington, DC
Data collection recommendations! Ideal is a combination of regular field monitoring to obtain volume
patterns combined with occasional surveys to collect more detailed data on origin-destination patterns, user characteristics, etc.

! Local authorities install:!at least one permanent automatic traffic counter at a control site where flows are high !permanent or temporary sites to count cycles at two or more other sites where measures to promote walking & cycling are being introduced.

But there are so many!
Which one?
What were our requirements?! An automated counter that:
! provided separate directional counts of both pedestrians and cyclists
! provided twenty-four (24) hour counts, with total counts at minimum fifteen (15) minute intervals
! reduced likelihood of mischievously enhanced counts or vandalism (invisible)
! could be powered by both battery and mains/solar power! could be installed on existing infrastructure! allowed remote access for data retrieval (GSM Modem or
similar)! provided a data output file that was either simple to use
(reformat/analyze) or complicated but was already in use by local governments and Main Roads
! was not cost prohibitive for smaller projects (<$100,000)
We created our own prototype using...• MetroCount box• Piezo electric strips• Ped sensor – IRISYS
system (used for shopper tracking)
• Plug-in box
• Telemetry solution (in Australia, Telstra’s ‘Next G’ GSM modem & sim card)
• Write program to transmit data
• Computer set up to receive data
