| Summary: | 碩士 === 國立中央大學 === 資訊工程研究所 === 99 === In telematics, the information of road speed are typically gathered through cameras or probe vehicles. In this work, we propose a web 2.0 system to enable gathering the information from the people, we called local gurus, who are familiar with the local area and the traffic. Two algorithms are proposed to calculate the road speed from a single local guru and the multiple local gurus. Through the Web 2.0 system, local gurus can contribute routes with information about road speed and time interval, and the route planning service can plan a route based on these information. The experience-wise group intelligence provided by this system can complement the experiment-wise group intelligence (e.g., using probe vehicles) in some cases, such as the area with no available probe vehicles.
