Assessment of Urban Traffic Environment Quality Based on Attribute Mathematical Theory

According to attribute mathematical theory, attribute recognition model in the assessment of urban traffic environment quality is established in this paper. Firstly, an index system is developed for assessing urban traffic environment according to automobile exhaust pollution and traffic noise; secondly, attribute measurement functions are rigorously constructed to compute attribute measurement of single index, as well as index weight is determined to compute synthetic attribute measurement; thirdly, a confidence criterion is established on the basis of the ordered evaluation sets; finally, An example is assessed to demonstrate the application of the proposed model and method, and the assessment results agree well with that of the matter-element method, which validates that the proposed model is feasible, effective and reliable in assessing urban traffic environment. The study indicates that the model is forthright in theory, simple and convenient in method, so it is applicable in practice.
