Through discussing on the importance and methods of detection and evaluation of load-carrying capacity of medium-small span highway bridges,especially the detection methods in n normal traffic states in dynamic test,this paper presents an integrated method for rapid evaluation of medium-small span existing in highway bridges.

Application of data mining in traffic state quantification and recognition;

Weighting calculation and judging method of regional traffic state based on information coordination;

Short-Term Traffic State Forecasting of Road Network Based on Nonparametric Regression;

Based on the analysis of the objectives and functions for developing evaluation indexes of urban traffic conditions,the meanings of urban traffic conditions were defined from multi-angles.

Then,a new traffic condition identification method based on fuzzy logic is put forward,establishing traffic volume and occupancy as input variables.
