BATON ROUGE - More than a month after the Capital Area Transit System launched its GPS software system, some bus riders complain the system is inaccurate and not user-friendly.

The Advocate reports the transit system, known as CATS, rolled out a website and smartphone app provided by RouteMatch Software at the end of January. It is supposed to show riders in real time when a bus will arrive at their stop.

CATS management has said the technology will improve rider experiences, and that its implementation fulfills promises from a tax election in April 2012.

Riders say the system has shortcomings.
