城市轨道交通制式分类及适用性

多制式轨道交通协同发展已成为城市轨道交通系统发展的大趋势。在介绍既有制式分类和各种制式城市轨道交通的基础上,从概念、特征、优缺点、适用性等方面对不同城市轨道交通制式进行对比,明确我国目前轨道交通是以地铁为主的多样性发展结构,指出在制式选择过程中存在制式分类标准不统一、选择过程考虑不周等问题。建议对制式进行准确分类,完善不同制式技术标准,基于城市发展,合理、科学地选择轨道交通制式,实现多制式轨道交通优势互补、互联互通、协调发展。

Classification and Applicability of Urban Rail Transit

Coordinated development of multifarious rail transit system has become a major trend in the development of urban rail transit.In this paper,existing standards of classification of rail transit systems are introduced and compared in terms of concepts,characteristics,merits and demerits and applicability.The multifarious development structure of urban rail transit systems in China,which mainly consist of subways,are highlighted.The problems such as inconsistency in classification standards,poor consideration of selection process and the weakness of long-term consciousness are elaborated.It is suggested that the classification standard for rail transit systems should be accurate,the technical specification for different classification standards should be specified and improved.Finally,it is proposed that the classification standards should be scientific and in line with the urban development so as to achieve coordinated,complementary and rational development of multifarious rail transit systems.
