Speed - The Map

The MBTA Bus Speeds map is a cool visualization of near real-time bus speeds in Boston. The map uses data from GPS positions to visualize the last three hours of traffic on the Boston bus network. There is also an option to view the map of the last 24 hours of bus traffic.

The speeds displayed on the map are calculated based on straight-line distances between the recorded GPS locations and not on the actual distance traveled by the buses. Therefore the speeds are probably under-estimations because the buses tend not to travel in straight lines but follow the Boston road network.
