Modelling of actual capacity of horizontally disturbed road sections in Shandong Province
In order to clarify the influence of lateral interference factors on the capacity of highway road sections and achieve the localisation of the capacity calculation model,in view of the current situation of highway traffic in Shandong Province,and taking the lateral interference road sections in Shandong Province as the research object,the lateral interference influencing factors of the capacity of basic road sections were qualitatively analysed from the three aspects of the traffic flow factors,the road infrastructure factors,and the type of land use,and Pearson's correlation was used to analyse the influence factors of horizontal interference on the capacity of basic road sections.The Pearson correlation analysis method was used to correlate the influence factors and influence coefficients of lateral interference,and according to the results of the correlation analysis,the independent variables of modelling were selected,and the localization model of the influence mechanism of lateral interference of the capacity of the basic road sections based on multivariate linear regression and BP neural network was constructed through the analytical software of SPSS and MATLAB,respectively.The results showed that the BP neural network-based localisation model of the capacity of the transverse interference section has higher accuracy.It was of great significance to predict the actual capacity accurately to solve the traffic congestion problem and improve the road service level.
