城市群城际铁路速度目标值影响因素分析

Influential Factors over Intercity Railway Speed Target Value in Urban Agglomeration

利用城际铁路快速、高效、便捷地连接城市群的中心城及其他城市已经成为了普遍的交通方式。合理的速度目标值是城市群城际铁路设计的一个重要标准。通过分析影响城市群城际铁路速度目标值的主要因素,从国际普遍采用的最高运营速度、城市群的交通可达性规划目标、主要技术标准与工程投资、动车性能能耗与运营成本、运营安全性及环境保护等多个方面进行分析,提出了城市群城际铁路合适的速度目标值的建议。

With rapid economic development and urbaniza-tion in China, the development model of single city has been altered to urban agglomeration with economic interde-pendence and common development. Intercity railway, a rapid, efficient and convenient transportation has become a common means to connect the central city and other cities in the agglomeration. The target of a reasonable speed is an important indicator for intercity railway in the urban ag- glomeration. By analyzing the main factors of the intercity railway speed target from aspects of the maximum operat- ing speed generally adopted in the world, the accessibility in city group planning, the main technical standards and engineering investment, the performance of energy con-sumption and operating costs of EMU, as well as the opera- tional safety and environmental protection, a suitable speed target value of urban agglomeration intercity railway is pro-posed.
