The ADVANCE project in the Chicago Metropolitan area is the largest operational test of Advanced Traveler Information System (ATIS) technologies in the U.S. This paper focuses on the process and computational features of the travel time data fusion algorithm in ADVANCE. Fusion is a critical step in providing dynamic route guidance for ATIS. This proposed algorithm is explained, and some practical and computational issues related to its implementation described.
