Embodiment Construction
[0049]An array radar-based evaluation method for urban road network traffic operation index, including: (1) under the urban road network road traffic environment, installing multiple array radar vehicle detection equipment on road sections with large traffic flow; (2) array radar vehicle detection equipment The detection equipment transmits the acquired real-time traffic parameter information to the background server in real time through the data communication device for standardized storage, and the background server performs standardized storage after filtering and cleaning the lost and abnormal data; the background server sends the real-time traffic parameter information to the core processing server; ( 3) The core processing server extracts the traffic flow and vehicle speed data of each array radar vehicle detection device, calculates the average traffic flow and average speed data of each road section on the basis of periodic granularity, and calculates the average traffic...

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.
Description
technical field [0001] The invention relates to the technical field of urban road network traffic operation evaluation, in particular to an array radar-based urban road network traffic operation index evaluation method and device. Background technique [0002] With the continuous development of social economy and the continuous increase of motor vehicles, the contradiction between supply and demand between existing road traffic resources and traffic volume is also increasing. The traffic congestion caused by this has gradually become a major problem affecting residents' travel. In order to meet the safe and convenient travel of the people, providing timely and accurate travel information services to the whole society is an important measure for the transportation industry to provide high-quality, diversified and multi-level transportation services to ensure and improve people's livelihood. The road traffic operation status is a concrete manifestation of the city's management...
