Using Probe Vehicle Data for Traffic State Estimation in Signalized Urban Networks
Probe Vehicle Data (PVD) is becoming more and more common for the collection of information about the traffic state. In most cases, the information that can be obtained from a probe vehicle refers to the position, the speed and the direction of movement at certain time intervals. Especially in urban networks, the raw GPS data needs a cleaning process to map the measured position to the road network. The cleaned information about positions in the network at fixed moments where GPS signals are collected can be used to derive travel time along certain routes.
