The ACT Government has invited comment on a Real Time Passenger Information System (RTPIS) for Canberra's ACTION buses. The commuter survey closes 26 August 2011. Unfortunately the link to the survey form is missing from the Community Engagement page about the project.
The survey canvasses options of web, mobile and SMS bus information, as well as screens at stations, major bus stops and shopping centers.
My preference would be for ACTION to make their web site compatible with mobile devices, rather than build a new mobile "app". They also need to ensure this meets accessibility standards for the disabled, as required by Australian law.
In addition screen should be placed at major stops, showing when busies depart. Obviously the same information should be provided free open access nonlinear via a standard interface to Google and anyone else who wants to use it.
