Chicago Transit Authority Map
The Chicago Transit Authority (CTA) have added real time bus tracking to their Google Map of routes and buses. Now travellers can not only view all the Chicago bus routes but all the Chicago buses.
Clicking on a mapped bus gives you information on the bus' schedule, informing you when it will arrive at its next few stops. Clicking on any of the stops on a route gives you information on when the next bus(es) are due to arrive at that stop.
The bus tags are colour-coded so that you can easily identify the bus' route. Each bus also comes with a route progress link which allows you to set an alarm for when a bus has reached a particular stop.
Many more transit maps are linked in the right hand column.
