County Connection bus riders can now go online to get real time information about bus locations and arrival times.

The Bus Tracker system relies on GPS data, allowing riders to look up locations and arrival times of all County Connection buses operating in central Contra Costa County and the San Ramon Valley.

To use the new system, go to www.cccta.org, click on "bus tracker is here" and plug in information about the bus route . Riders can set up personalized accounts to get alerts about the next bus arrival times on their favorite routes.

"The implementation of Bus Tracker is the latest upgrade to the on-board computer system", said Anne Muzzini, the bus agency's planning director. "This upgrade will give bus riders peace of mind and that is particularly important in a suburban area like ours because the bus comes less often than in an urban area."

Bus Tracker was activated Wednesday. For assistance in using the system, call 925-676-7500.
