Abstract
This study is about the project early operation content of the green road development, takes full account of the operation items of various stages of the life cycle, by the use of special case define the Project Definition Rating Index (PDRI). PDRI assessment framework, defining the need and scope of green road project development operations in the metropolitan area, and inquire set various assessment indicators of the work to complete building the overall indicator assessment system. From research in a policy aspect, as well as data collection out of instances of project case, research program obtains evaluation index operation item, and by semistructured interviews supplements insufficient evaluation index items and particularity needs. Research results will be beneficial to the application in the metropolitan regional overall development project. Building green road index evaluation system helps to avoid the environmental impact brought about by land development, reduce damage to people's life safety as a consequence from needs for road maintenance, alleviate future maintenance and management expenses, and is in line with the expected benefit of green road project sustainable development.
Highlights
The term "green" is widely used in various industries and areas of expertise
Taoyuan Zhonglu planning area is located in the center of the three urban planning areas of Nankan, Taoyuan City and Neili, with a total development area of about 143 hectares
Many studies in the literature divide green roads into three constructed forms of bridges, tunnels and embankments, but the metropolitan road development carries more specific needs. This three infrastructure cannot meet the needs of the metropolitan road system [1]
Summary
A lot of research literature for the scope of green roads such as the meaning, operations and performance evaluation has different definitions and final performance requirements. Major operations include the roads, five big pipeline projects, regional drainage and water conservancy projects, landscape engineering, flood detention and disaster prevention in Zhonglu Park. The whole project takes full advantage of the local environment and regional development needs, provides disaster prevention, disaster mitigation, emergency rescue and temporary shelter space, and brings into play the concept of sustainable environment. In response to future regional development trends, regarding the operation scope of metropolitan green road development, including traffic control engineering, pavement and road engineering, common conduit, pedestrian environment and other projects, this study defines operating scopes at different stages of planning, design, construction, maintenance and management. The research results will be used by authority as future reference for performance assessment about segment expropriation project
