This map is a simulation based on the timetables published by TransLink (Department of Transport and Main Roads Division).
Vehicles and stops are interactive, list departures from a specific stop right now (obtained via the OPIA API), Want to see what route a vehicle is taking? Click and follow its movement, and see what stops are visited next.
Currently a working system exists only as a proof of concept and not exposed to the public. The simulation engine is written in pure PHP with focus on scalability, using CakePHP Framework, Redis.io and CakeResque to manage jobs and process in parallel and across servers if required.
A short demonstration video of the working prototype is available on Youtube.
