Bus signal priority method assessment based on multiple attribute group decision

This thesis puts forward a bus signal priority assessment index system, which including bus traffic efficiency, intersection traffic efficiency, implementation difficulty factors of methods and so on. Because there are some missing, uncertain or fuzzy indices, and relevance between indices. And decision-makers would have their subjective preferences. The thesis then puts forward a bus signal priority assessment method based on uncertain multiple attribute group decision. At the last part, the thesis takes Guangzhou Tianhe Road and Tiyudong Road intersection as an example to assess bus signal priority method, including no priority, all priority and general fuzzy control priority, and verify the effectiveness of the method.
