The External Characteristics and Mechanism of Urban Road Corridors to Agglomeration: Case Study for Guangzhou, China
Round 1
Reviewer 1 Report
A well-written and presented manuscript. The subject of road corridors is very interesting, especially in this type of city (a very fast-developed city). The results of the analysis present a scientific interest. However, it is needed an analytical explanation of the differences that have revealed from the analysis. Table 2 and 3, for example, if there are any reasons why in 800/1000 m the proportions are less than in the other distances. There are no references to the evolution of population and economic analysis.

Point 1: A well-written and presented manuscript. The subject of road corridors is very interesting, especially in this type of city (a very fast-developed city). The results of the analysis present a scientific interest.
Response 1: All authors highly appreciate your kindly encouragement and support.
Point 2: However, it is needed an analytical explanation of the differences that have revealed from the analysis. Table 2 and 3, for example, if there are any reasons why in 800/1000 m the proportions are less than in the other distances.
Response 2: Thanks for your suggestion. We think that is a good and in-depth question. The study is only to explore whether urban roads have the same corridor effect and the influence radius on roads of different districts, levels and directions for the buildings and land agglomeration, so as to summarize specific external characteristics and performance. According to comparative research, the result shows the agglomeration power is mainly caused by private transportation. But it still can't explain why corridor effect shows different influence radius on expressway outside or in the Inner Fringe (show as Table 2 and 3), I suppose that are caused by the interaction between the distance between roads, the convenience of transportation and the scale of building development. We can study the problem in the future.
Point 3: There are no references to the evolution of population and economic analysis.
Response 3: Thanks for your suggestion. This article adds the evolution of population and economic analysis of Guangzhou（Line.92-95）

Reviewer 2 Report
This is the continuation of former manuscript numbered as “land-1578647”. I formulated then some remarks with general opinion “major revision” but the manuscript was rejected by the editor. Now, I am satisfied with consideration of all my earlier remarks and I not formulate any others. In my opinion, the manuscript can be published.
