The invention discloses a UWB-based expressway traffic flow parameter monitoring method. The method comprises the following steps: establishing a road coordinate system model; acquiring position information P of a vehicle in the road coordinate system model; and calculating traffic flow parameters according to the position information. The invention also discloses a monitoring system of the method, and the system comprises the electronic tag which is installed on a vehicle and is used for transmitting a position signal; the plurality of base stations are installed on the roadside at intervals and are used for receiving the position signals sent by the electronic tags and generating position parameters; and the central system is in communication connection with each base station and is used for acquiring the position parameters generated by each base station and calculating traffic flow parameters according to the position parameters. Through obtaining vehicle position information at different moments, real-time detection of space average speed, traffic flow density and traffic volume of vehicles in a monitoring area can be realized, data support is provided for traffic management and planning, and road traffic efficiency and safety are improved. The method has the advantages of high precision, low cost, simple installation and the like.
