An Evaluation and Application Method of Urban Center Accessibility

Abstract

The invention discloses a method of evaluation and application of accessibility of an urban center, and relates to the technical field of urban planning. The method comprises the steps: firstly, confirming evaluation indexes of the accessibility of the urban center, and building an evaluation model of the accessibility of the urban center; obtaining vector topographic map data, and checking and adjusting the vector topographic map data on the basic of actual state measurement; then, obtaining data of the various indexes through calculation of AUTOCAD software, inputting the data of the indexes into the evaluation model, and obtaining an index of the accessibility of the urban center; and finally, based on the index, serving the AUTOCAD software as a working platform, and improving the accessibility of the urban center through continuous optimization-evaluation. The method is based on objective rational data, an evaluation mode of the accessibility is simplified, the data are easy to obtain, the accuracy is high, adjustment can be conducted in a directly visual mode, and the accessibility of the urban center is improved.

Description

technical field [0001] The invention relates to an evaluation and application method of accessibility in a city center area, and belongs to the technical field of urban planning. Background technique [0002] Accessibility, simply put, refers to the ease with which a place can be reached from another place, which can be measured by spatial distance, topological distance, journey distance, travel time or transportation cost. Within an urbanized area, accessibility is defined by the interaction of different activities and the resulting traffic behavior, measured by the ease with which activities in one place can be accessed from other places under given traffic conditions . Accessibility thus expresses the linkages between different locations within a territory and measures the relative advantages of locating an activity in different locations. [0003] There are mainly four existing methods for the measurement of accessibility: [0004] 1. Distance measure method [0005]...
