四川天府新区交通服务均等化分析

Equalization Analysis of Traffic Service in Tianfu New Area of Sichuan Province

以RS和GIS技术为支撑,基于四川省第一次全国地理国情普查成果数据、高分辨率遥感影像和基础测绘成果数据,结合路网密度指数、空间覆盖度和交通通达性等指标以及相关规划资料,利用影像解译、外业核查和地学统计等方法对四川天府新区交通服务水平进行了分析评价。结果表明,天府新区交通网格局基本成型,综合交通运输体系初步建立,交通设施配置水平显著提高,道路通达性发展态势良好,但交通服务均等化效果不理想,整体呈现区位差异,城乡发展差距较明显。

Based on the first national geographical conditions census achievement data, high-resolution remote sensing images and basic surveying and mapping achievement data in Sichuan Province, taking RS and GIS technologies as support, combining with the road network density index, spatial coverage, traffic accessibility and other relevant planning data, we used the image interpretation method, the field verification method and geoscience statistics method to analyze and appraise the level of traffic service in Tianfu New Area of Sichuan Province.The results show that the traffic network in Tianfu New Area is basically formed, and the comprehensive transportation system is initially formed. The allocation level of traffic facilities is significantly improved, and the accessibility of the road is in good condition. However, the equalization of traffic service is not satisfactory. Overall, there are differences in location, and urban-rural development gap is more obvious.
