广佛环线对珠三角地区城际轨道交通网通达性的影响

广佛环线属于轨道交通网络中圈层的几何范畴,为广佛都市圈的城际环线。该线连接了广佛地区重要的交通枢纽,并与珠三角地区城际轨道交通线网规划中8条城际轨道交通线路衔接,是珠三角地区城际轨道交通网"三环"中最为重要的"一环"。通过对广佛环线功能定位分析和通达性计算表明:该线不仅满足了沿线地区客流需求,推动了广佛同城化进程,同时还将以广州为中心的放射形线路紧密的组合在一起,提高了珠三角地区城际轨道交通线网的通达性,提升了线网服务效率。

The Effect of the Guangfo Circle Line on the Accessibility of Inter City Rail Transit Network in Zhusanjiao Area

Guangfo circle line is the inter city circle line in Guangfo area, which belongs to the geometric categories of the rail traffic network＇s spheres and layers. It connects a great number of important transit hubs; and joins eight inter city rail transit lines. It is the most important circie line in the ＂three circle＂ of the line network. Through analyzing the function and calculation for the accessibility of the Guangfo circle line, it shows that： the Guangfo circle line not only meets the passenger flow requirements and promotes the process of the Guangfo city, but also improves the accessibility of the line network and service efficiency.
