Traffic speed -- Measurement, Global Positioning System, Travel time (Traffic engineering)




This research investigates the potential of using archived high resolution bus data to describe traffic speeds on roadways; effectively using buses as probe vehicles. This is not only a simple and inexpensive way for transit agencies to better understand their road networks, but also utilizing buses as probe vehicles provides the potential to understand traffic conditions, to understand potential consequences of changes in road infrastructure, and many aspects of traffic utilizing already archived data. Using speed information derived from high resolution bus GPS data and stationary sensor data, this research examines the accuracy of bus GPS data and also discusses advantages, shortcomings, and limitations of utilizing GPS bus data to represent roadway speeds.
