Having attended the Bavaria City Racing Dublin on the bank holiday Sunday, which I thought was a bit of a damp squib. Lots of people in town to see the event despite the wet and cold, large sections of the route were masked off from viewing and one had to rely on a video image from to get any sense of the event. A friend who paid to get into the paddocks was equally disappointed with the organisations and what could be seen.
While standing in Dame Street for over an hour I observed the Dublin Bus Real Time Passenger Information (RTPI) board was still displaying arrival times for various buses even though the route was closed all afternoon. So I checked the Dublin Bus website to make sure I fully understood RTPI, I thought it tracks the position of the bus and updates the commuter how soon the bus will arrive at that bus stop. This is what is says on the Dublin Bus website.
How does it work?
Buses are equipped with an on board computer, GPS navigation system and a radio which allows them to report their position to a central computer. The central computer then estimates how long the bus will take to reach all bus stops along the route.
So how was it displaying arrival times for various buses on Sunday when the services were either cancelled or diverted to other streets?
