Abstract

The embodiment of the invention provides a congestion data determination method and a congestion data determination device. The method comprises the following steps: according to acquired road sectiondata, determining feature information of a road section, wherein the feature information comprises average speed, traffic stream density, speed threshold value and a data effective value; according to the feature information, determining congestion data through a predetermined congestion model, wherein the congestion model comprises a nonlinear regression model and a predetermined quasi-logisticregression model. Thus, based on multiple feature information of the road section, determination of the congestion data can be executed based on the nonlinear regression model and the predetermined quasi-logistic regression model, a problem of accuracy rate of the congestion data determined based a single index is overcome, accuracy rate of the congestion data is improved, and calculation operations are simplified.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for determining congestion data. Background technique [0002] For the congestion of urban roads or expressways, the currently commonly used indicators are based on a single indicator. For example, Beijing is based on travel time, the US Federal Vehicle Administration is based on travel delay time, and the data of INRIX in Europe is based on the ratio of actual speed to free flow speed. However, due to the lack of checkpoints on the expressway and the inaccurate measurement data of toll stations, the congestion index determined based on a single index will lead to inaccurate calculation results of the congestion index due to low data quality. Contents of the invention [0003] In view of the above problems, the embodiment of the present application provides a method for determining congestion data, which can solve the problem of low accura...
