Travel time estimation is an important component of Intelligent Transportation System (ITS). Many techniques for estimating travel time on various routes based on different types of sensors were proposed. In the past, stationary sensors were more popular, but they came with inflexibility, extra investment, and disruption to traffic flow during installation and maintenance. Global Positioning System (GPS) devices can also be used as mobile sensors but the signal penetration can be limited in the city environment. In this paper, we propose architecture of a context aware system for travel time estimation based on cellular probes in city environment. A cellular probe technique is our preference since necessary infrastructure is already in place without the weaknesses of stationary sensor techniques and GPS devices. The context analysis module in our system helps eliminate unrelated cellular probes from input data. Traffic data delivery methods are also discussed. Our system is very helpful for routes selection especially in the metropolitan area. The architecture of our system is open, flexible, extensible, and it can develop an evolutionary.
