Problems solved by technology

[0004] However, traffic information cannot be simply understood as a linear relationship, and the reliability and accuracy of the methods for determining traffic information in the prior art are not high enough
This in turn leads to inaccurate forecasts of traffic pollution emissions.

Abstract

The invention provides a traffic information determining method and a traffic pollution emission predicting method. The traffic information determining method and a traffic pollution emission predicting method realize road speed estimation through carrying out deep multi-layer self-attention processing on historical road speeds in a plurality of historical periods, and realize road flow estimationthrough performing deep key-value pair attention processing on candidate attribute information and candidate road flow of a plurality of similar roads, thereby estimating the missing road speed and road flow respectively according to change features of different traffic information, improving the precision and reliability of traffic information, performs traffic pollution emission prediction on the basis of the traffic information, and improving the precision of the traffic pollution emission prediction.

Description

technical field [0001] The present application relates to intelligent transportation technology, and in particular, to a method for determining traffic information and a method for predicting traffic pollution emissions. Background technique [0002] In the fields of transportation and environmental protection, it is necessary to measure and monitor the traffic information on urban roads and road pollution discharge information based on traffic information. Real-time traffic information and pollution emission information can help people arrange travel methods and travel time, and the pollution emission information is also of great help for air pollution traceability and other issues. Traffic information usually includes road speed and road flow. However, both speed and flow have different degrees of missing problems, and it is necessary to determine the missing traffic information. [0003] In the related art, the missing traffic information is usually determined by a linea...
