The invention discloses an intersection traffic flow parameter monitoring method and system based on UWB. The monitoring method comprises the following steps: S1, establishing an intersection coordinate system model; s2, acquiring position information P (xi, yi) of the vehicle; wherein xi is the abscissa of the vehicle in the intersection coordinate system model at the moment i, and yi is the ordinate of the vehicle in the intersection coordinate system model at the moment i; s3, traffic flow parameters are calculated according to the position information P (xi, yi) of the vehicle; the traffic flow parameters comprise vehicle flow directions, traffic volumes Q in different flow directions and queuing lengths (ti). By installing the UWB base station at the intersection to obtain the position information of the vehicles in real time, the flow direction of the vehicles in the intersection, the traffic volume in different flow directions and the queuing length can be monitored in real time, accurate and reliable traffic flow information is provided for traffic control, and signal optimization and evaluation are conducted on the intersection in real time.
