Abstract: These days Wireless Location Technology (WLT) develops very fast. The accuracy of mobile location has been remarkably improved, which provides the possibility of using cellular probes to give a fairly good estimate of travel speed or travel time in an urban region. Probe-based traffic monitoring system using cellular technology has much lower cost than the traditional method using Global Positioning System (GPS) and it can improve the utilisation of the existing facilities. This paper summarises several previous studies and field tests, analyses the raw cell phone data from one wireless carrier and tries to address the potential issues and feasible additional refinement for the future field deployment and operational application.
