Abstract
We present new algorithms that use transit vehicles as probes for determining traffic speeds and travel times along freeways and other primary arterials. We describe the use of vehicle locations produced by an automatic vehicle location (AVL) system, the King County Metro Transit AVL System, to construct "speed sensors" on every road segment over which transit vehicles travel. We present the resulting estimates of speed and use that data to estimate travel times
