The name of ″The Economic Belt of the Silk Road and the Silk Road on the Sea in the Twenty-first Century ″ (abbreviated as ″the Belt and Road″ or ″B & R″) originated from the ″Silk Road ″. Research findings on ″B & R″ published in recent years involve topics such as ″economy ″, ″trade ″, ″finance ″, etc. There have been few Chinese literatures on ″the Belt and Road ″ from the perspective of world heritage. Ferdinand von Richthofen (1833-1905) first named the Silk Road in his book China: The Result of my Travels and the Studies based Thereon (1877-1912, 5 vols. and atlas). In the process of using the name in different countries, times and disciplines, the Silk Road has derived many names by geographical landform, place name & location, transportation, trade goods and cultural concept. From its first initiative on September 7, 2013, to being officially launched in March 28, 2015, the vision and action of ″B & R″ went through a process of understanding and planning. ″B & R″ is named through long social practice, yet it is still open to discussion for pure academic accuracy. Although ″B & R″ is a linear or banded ″road″, the scope of its space can be extended to the world. Its core scope ranges from the important nodes along the new Silk Road (key economic towns, harbors, customs and islands, etc.), its main areas to the road net of the main lines. Its substantial scope includes the sum of national economic hinterland, which is reached by important nodes, main areas and road nets along the new Silk Road. Its buffer zone covers the territories, territorial waters and airspace boundaries of countries along the new Silk Road. Its virtual scope is the area covered and radiated by the modern communication network. The traffic thoroughfare of ″B & R″ includes thoroughfare in land (land routes & water routes in land), thoroughfare in ocean (sea routes through islands and reefs), aviation thoroughfare and network thoroughfare. The traffic terminal of ″B & R″ consists of points of departure, destination, intermediate transit (in the Silk Road network) and nodal (of land, sea and air lines). Theoretically, each region, province and city in China can become a starting point, or point of origin, of ″the Silk Road″. But the transfer point and nodal point must have the corresponding conditions, which are the key sites for infrastructure construction. The traffic type of ″B & R″ composed of transport vehicles and routes is complex and varied. There are 31 types of traffic combinations and 325 types of traffic arrangement. The construction and maintenance of ″B & R″ need safety and security. ″B & R″ will represent the mainstream of world civilization in the early Twenty-first Century.
