珠三角城际轨道交通是随着广东省经济高速发展出现的一种新型的交通模式,它不同于普通铁路,也有别与地铁,在尚没有设计标准可参考的情况下,建设标准的确定将直接影响项目的工程投资、运营效益等,因此,结合项目的实际情况合理确定标准将显得非常重要。速度目标值作为轨道交通项目影响全局的核心技术指标,站在珠三角城际轨道交通网的高度,通过与路网速度目标的匹配、与站间距离的适应性、动车组性能的发挥等方面展开论述,通过认真比选最终确定本线采用200km/h的速度目标值,其中站站停采用140km/h的速度目标值,大站停采用200km/h的速度目标值。 Pearl River Delta Intercity Rail Transit is a new type of traffic mode that emerges along with the rapid economic development in Guangdong Province. It is different from ordinary railways and metro stations. In the absence of any design standards, the determination of construction standards It will directly affect the project investment and operating benefit of the project. Therefore, it is very important to determine the standard reasonably in combination with the actual situation of the project. As the core technical indicator of the overall impact of the rail transit project, the target value of speed stands at the height of the inter-city rail transit network in the Pearl River Delta. It matches the speed target of the road network, the adaptability to the distance between stations and the performance of the EMU Expand the discussion, through careful selection and final determination of this line speed target of 200km / h, of which 140km / h speed target stop using the station, the station stop using 200km / h speed target.
