The Arterial Travel Time System (ATTS) is described. ATTS uses vehicle signatures from wireless magnetic sensors embedded in the pavement and a matching algorithm to re-identify vehicles between reference locations. It accurately estimates travel time distributions in real time, and also derives various other performance measures, including delay, level of service, and emissions. Results from the ATTS deployments in Chula Vista, CA, USA and New York City, USA are discussed. With signal phase information, ATTS can help improve signal settings, and identify vehicles running a red light or speeding.
