Abstract :
We describe a method for real-time monitoring of data generated by traffic sensors. We provide a system architecture and discuss three key components: (1) a streaming query processor that is used to reduce the volume of data; (2) a pattern-matching module that is used to detect when a developing traffic situation resembles one flagged earlier; and (3) an interface that efficiently displays the stream of sensor data in a user-configurable manner.
