It was set up to fail with such a low frequency to begin with and such a short trial period.
I am more worried about the disorganisation/deliberate sabotage (take your pick) by the drivers and others involved in organising stop locations etc. as outlined in the lower article. It is simply not acceptable to have such poor customer service on any bus route, especially a highly publicised trial. Great way to erode the general public's already low confidence in the bus network.
Integrated ticketing is a matter for State Government procrastination.
This trial has now been extended until april 17th. In the email they mention that passenger loadings have been well below the target so far, but that this extension will run through the busiest time of the year for transPerth, and that it will be reviewed after the extension. So it looks like they do want this service after all! Or at least need to look like they want it.
