摘要/Abstract

摘要：

在总结城市群交通网络运输方式多元化、交通节点等级化、结构运行高效化等基本特征的基础上,本文基于GIS空间分析平台构建了城市群交通网络载流模型（Traffic Network Flow-carrying Model, TNFM）,以山东半岛城市群为研究案例区,综合评价和对比了交通网络及各类型交通线路的理论与实际载流能力,得出各行政单元交通线路的缺口指数,并据此提出城市群交通网络的优化与提升方案。研究结果表明：TNFM模型可以有效地评价城市群交通网络的载流能力并得出各行政单元和道路类型的缺口里程,为城市群交通体系规划提供科学依据;山东半岛城市群国道、省道和铁路建设不足,部分城市主干道分流不畅,60%的县市存在各级道路短缺,但高铁和县乡道可以满足载流需求;未来应重点加强上述4类交通线路的建设,完善交通线路间的接口系统,充分发挥高铁和县道的分流作用。

Abstract:

Based on the summary of the diversified modes, multi-level traffic nodes, efficient operation and structure, the evaluation model of the flow-carrying capacity of the urban agglomeration traffic network is constructed with GIS platform. Take Shandong Peninsula urban agglomeration （SPUA） as a case, this study aims to evaluate and optimize the comprehensive transportation network in urban agglomerations with traffic network flow-carrying model （TNFM）. First, the contrast analytical matrix was constructed, in which the practical flow-carrying values for traffic lines can be compared with their theoretical values. Second, using the spatial analysis tool of GIS, the performances of comprehensive traffic network as well as every type of traffic lines were evaluated. The national road, provincial road and railway of the urban agglomeration is inadequate. Diversion of some urban trunk road is poor. 60% of the administrative units at all levels have shortage of road. High-speed rail and county road can meet the current carrying requirements. In the future, SPUA should focus on strengthening the construction of the above four types of traffic lines, improve the traffic interface system, and give full diversion to the role of high-speed rail and county road.

Key words: urban agglomeration, traffic network, traffic optimization, territory coefficient model, Shandong peninsula, Traffic Network Flow-carring Model
