摘 要: 优化路网结构是缓解旧城改造工程因开发强度提高而导致的城市中心区交通压力难以疏解问题的重要手段之一。以沙坪坝综合交通枢纽项目开发为例,对项目实施前后的不同情况(“二环八射”、“三环十射”和枢纽改造方案)进行对比分析。结果显示,通过枢纽改造方案的实施,相对于“二环八射”的路网结构,各个节点的可达性平均提高了26.74%,网络效率提升了12%,全局整合度平均提高了99.85%. 研究表明,枢纽改造方案使节点可达性与网络效率显著提高,也使街区空间得到整合;但沙坪坝区域的路网结构与理想状况还有一定差距,特别是交通网络效率仍然偏低。建议进一步从节点、网络和街区的连通等方面改善区域道路的网络性能,促进区域网络的优化。
关 键 词: 计算机应用其他学科;复杂网络;空间句法;节点可达性;网络效率;全局整合度

Abstract: Optimizing the network structure is one of the important means to relieve the traffic pressure of the downtown area caused by the development of the old city reconstruction project. Taking Shapingba comprehensive transportation hub project development as an example, the difference between before and after the implementation of the project (“two-ring eight-shot”, “three-ring ten-shot” and traffic reconstruction scheme) for comparative analysis is analyzed. The results show that, compared to the “two-ring eight-shot” of the road network structure, the accessibility of each node is increased by 26.74% compared with the implementation of the project, network efficiency is increased by 12%, the global integration is improved by an average of 99.85%. The research shows that the scheme makes the node accessibility and network efficiency significantly improved, and also makes the space of the block to be integrated. But, there is a certain gap between the network structure and the ideal situation of Shapingba region, especially the traffic network efficiency is still low. Recommendations are proposed to further improve the performance of the regional road network from the nodes, networks and neighborhoods, to promote regional network optimization.
Key words: other subjects of computer applications; complex network; space syntax; reachability of nodes; network efficiency; global integration
