Study on Traffic Data Pre-processing Technology based on RTMS
Traffic flow data is the base of traffic real-time control, traffic analysis and support of traffic management. Due to detection equipment failure, transmission failure, and outside interferences, there exist various errors in the original detected data and which will influence information accuracy. And the non-unified data standards also bring the difficulty and interference to the data analysis, mining and integration. This paper gives the detailed analysis of the error data types and causes of the problem based on RTMS, as well as put forward the modified schedule that suit to three types of incorrect data and which are time points deviation, data loss and data error. At last, Beijing RTMS detection data is taken for explanation.
