Abstract

Urbanization has been a flourishing process in a wide range of developing countries. The planning and construction of public service facilities is a crucial component of this process. Existing planning methods of public service facilities focused on macroscopic indicators like population and GDP. In this way, accessibility and transportation conditions were neglected. Four typical counties in China were selected as samples where travel surveys and questionnaire surveys on public service facilities were conducted. Taking education and medical care as representative public service facilities, this study used geographic information processing to connect the locations of public service facilities at all levels with the urban land accessibility. Then, analysis of variance was used to obtain correlations between the level of public service facilities and the urban land accessibility. The results showed that the urban land accessibility of locations of public service facilities follows a normal distribution. Categories of facilities showed significant difference on urban land accessibility. Therefore, intervals of urban land accessibility of locations of public service facilities within one standard deviation from the mean were constructed by category. These intervals built a connection between transportation conditions with locations of public service facilities. Corresponding relation of carbon emission of facility-related trips and urban land accessibility was established as an example of an application. Carbon emissions caused by facility-related trips can be reduced by locating facilities at locations with appropriate urban land accessibility.

Highlights

Urbanization has been a flourishing process in a wide range of developing countries
The national urban built-up area has increased by 47,000 square kilometers, or 6.7 times greater since the end of 1981 [1]
The core of the new urbanization strategy is to control the scale of urban land use

Summary

Introduction

Urbanization has been a flourishing process in a wide range of developing countries. Take China as an example; at the end of 2016, the national urban built-up area was54,000 square kilometers. Urbanization has been a flourishing process in a wide range of developing countries. Take China as an example; at the end of 2016, the national urban built-up area was. The national urban built-up area has increased by 47,000 square kilometers, or 6.7 times greater since the end of 1981 [1]. In 2014, the central government proposed a new urbanization strategy. The core of the new urbanization strategy is to control the scale of urban land use. China’s urban development has changed from incremental expansion in the past to content-based growth
