Abstract: The Study for Chengdu 2nd Ring Road Reconstruction Planning, compared with the similar projects, has four innovations which are mainly in planning concept, research method, evaluation method and introduction of Bus Rapid Transit(BRT). The research methodology has four-step process: study for goals system, special topics, draft planning and final planning. The goal system research locks goals in four sorts and eighteen sub-sorts and gives all factors different weights to evaluate. The research for special topics covers six foundational subjects in final reports. During the process of draft planning, according to road capacity, the vehicle speed and public transportation system, three sorts of draft plans were received, which had been compared not only based on the technical standard, but also on project cost and social benefit balance. In the final planning the best draft plan had been deepen and optimized. Besides, the evaluation method includes the citizen investigation, consultation to local executive departments, expert evaluation and weighting and administrative decisions.
