Study of Bus Rapid Transit System Evaluation Based on Gray Extension Matter-element Model

The paper mixes extension theory and gray clustering method, and constructs the evaluation system of the bus rapid transit system based on gray extension matter-element model, using the evaluation grade of bus rapid transit system, the indicator evaluation standard and the basic characteristics value as the matter elements, applying gray clustering method to calculate the weight and the correlation degree. The example calculation shows that the model can not only reflect the overall development level of the rapid transit system comprehensively, but also identify the relative difference between the specific indicators and the standard values.
