Urban road network traffic operation index evaluation method and device based on array radar

The invention relates to an urban road network traffic operation index evaluation method based on an array radar. The urban road network traffic operation index evaluation method based on the array radar comprises the following steps: installing array radar vehicle detecting equipment on a road section with relatively great traffic flow, and transmitting the obtained real-time traffic parameter information to a background server; extracting traffic flow and vehicle speed data through a core processing server, calculating the average traffic flow and the average speed data of each road section, calculating the average traffic flow density of each road section, extracting traffic operation indexes of each road section of the road network, calculating the classified highway traffic operation indexes, polymerizing and analyzing the integral traffic operation indexes of the road network, and judging the traffic operation state level of the existing road network; issuing information to the public through an issuing terminal. The invention further discloses an urban road network traffic operation index evaluation device based on the array radar. The accuracy of acquiring road section traffic events is increased, the large-area traffic information collecting cost is lowered, the system operation evaluation accuracy and the traffic management service level are improved.
