The embodiment of the invention discloses a traffic event estimation method, device and system based on a PWSL hybrid observer. The method comprises the following steps: establishing communication connection between roadside equipment and a vehicle based on a beacon mechanism; establishing a PWSL traffic model, and combining the PWSL traffic model with a hybrid observer to construct a PWSL hybrid observer; estimating a traffic event by adopting the PWSL hybrid observer to obtain an estimation result; based on the estimation result, traffic information collected by the roadside equipment from the vehicle is adopted to realize detection of a traffic event; the traffic information is related to vehicle speed change. According to the embodiment of the invention, the communication connection between the roadside equipment and the vehicle is established based on the beacon mechanism, so that the loss rate of data transmission can be effectively reduced; in addition, traffic events are estimated and detected based on the designed PWSL hybrid observer and the lane changing speed mechanism, and compared with an existing traffic event estimation method, the method has higher flexibility and estimation accuracy.
