Traffic congestion and associated impacts such as air pollution and added fuel consumption pose major concerns to the public. Increasing the capacity of the roadways is expensive and in some areas where the land is scarce is not an option. Improving the efficiency of the current transportation system through the implementation of advanced technologies may alleviate the traffic congestion. Real-time traffic surveillance is one of the most important components of such approach. The Real-time travel information has also application in advanced travel advisory systems. Emergency management agencies such as police, fire stations and ambulance dispatchers may also benefit from the real time traffic information in routing their vehicles through the transportation network to save lives.Among all traffic related parameters, travel time is of special importance. Traditionally, floating car data have been used as the primary source of ground truth for measuring the quality of real-time travel time provided by traffic surveillance systems. This seminar reviews new and emerging technologies for travel time data collection and estimation including crowd sourced vehicular probe and Bluetooth generated data. Different applications of such data in both operation and planning will be presented.
