Background
tod (Transit-Oriented-Development) is a "public transportation Oriented" Development model. The concept is proposed by the new city sense representing the character Biget-Karsol, and is a kind of walk urban area taking public transportation as the center and comprehensively developing to solve the unrestricted spread of the United states city after the second battle. The public transportation is mainly rail transportation such as subways, light rails and the like and bus trunk lines, and then urban areas integrating work, business, culture, education, living and the like are built by taking bus stops as centers and 400-800 m (5-10 min walking path) as radiuses. So as to realize an organic coordination mode of compact development of each city group. tod is an internationally representative urban community development model. Meanwhile, the method is also one of the most representative modes of newcastle disease. Is widely used in urban development, especially in areas where cities are not developed in pieces, public transportation is introduced by soliciting land for planning development areas at a lower price in advance, time difference for developing land price is formed, then 'prepared land' with perfect infrastructure is sold, and the government recovers the prior investment of public transportation from the return of land rise value.
The existing TOD concept is developed by public transportation commission, can not be combined with a mobile data network to change traditional user travel traffic analysis, and can not be used for deeply analyzing adaptability of TOD development of comprehensive hub area track sites from the aspects of land, traffic, economy, population relations and the like, so an evaluation method based on TOD concept for building a comprehensive hub area system model is needed.

as shown in FIG. 1, a scatter plot determines which nodes are adjacent to a centrally located dark node. Let k=2, e be the radius shown in the figure. Since the graph contains three nodes within an epsilon-radius, 3>k, the area within the circle in the graph is considered a dense area within which the epsilon-radius algorithm will be chosen to be employed. Thus, the centrally located dark node will connect with the other three dark nodes within the circle.
