The Department of Transport has had in place 11 sites to record bicycle movements. In 2012 they added five sites bringing the total number of sites to 16. The sites are on Principal Shared Paths (PSP) and Recreational Shared Paths (RSP); that is routes considered to be the major commuter routes into and out of the Perth CBD.
In summary the 2012 count recorded a total of 3,722,188 movements at the existing sites with the most active month being October 2012. The new count sites recorded 526,050 movements from August 2012 to December 2012.
The 2011 count data suggests that there was 3,295,832 movements at the existing count sites. This suggests an increase of 426,356 movements in 2012 or 12% (the Department of Transport suggests 14%).

Where are the Perth Bicycle Movements in 2012
Without a doubt a major express point for the City of Perth is the Kwinana PSP with cyclists either heading through South Perth or out and across the Mt Henry Bridge. This is maybe a sign of the nature of the infrastructure which encourages riding from the southern suburbs into the Perth CBD. The other access points have similar traffic levels, around the 10% mark and as would be expected as the counters move further out from the city, the numbers drop off.
Looking at routes such as the Fremantle – Perth PSP which is incomplete and lacks a good connection into Fremantle we see the traffic movement declining by 57% between the count point at Subiaco (110,674 movements) and the count point at Grant Street Station (46,716 movements) (September to December).
Similarly on the northern PSP, the traffic movements counted at Leederville (128,462 movements) are 57% higher compared to Karrinyup Road for the same period (September to December) (55,158).
If we do the same exercise on the Kwinana PSP, the traffic movements between the Narrows between September and December where 253,240 and at Mt Henry Bridge there was 139,953 movements, a 44% drop in movements. However we don’t have count data for the cyclists who turn off at the Canning Bridge to head west towards Fremantle. I suspect if we include them in this comparison the drop in traffic movements south of Perth will be even less.
I suggest that we really see the effect of infrastructure here, with much greater movements on the Kwinana Freeway and cyclists riding further distances because of the infrastructure. It would be interesting to see what would happen to traffic movements on the Fremantle PSP if we have a good connection point over the Swan River at North Fremantle.
Whilst not a comparison by any means (two hours of data on one day a year) the Super Tuesday count for Fremantle suggests that the main arterial route for cyclists is over the Swan River at the Old Fremantle Traffic Bridge.
It will be interesting to revisit this data at the end of 2013, more so if the Department of Transport where to put in place a counter in the City of Melville to get a better handle on movements between the Canning Bridge and Fremantle. Even a counter on the Canning Bridge or on the RSP around the river at the Raffles Hotel would be useful.
The Department of Transport maintains various spreadsheets collating the data from 2008. Just visit the Department’s website and follow the links through to cycling and then the WA Bicycle Network for the bicycle count graphs going back to 2008.
