Abstract: As the backbone line for the traffic corridor of the urban agglomeration in middle Zhejiang Province, Jinhua-Yiwu-Dongyang regional rail transit engineering plays the role of cohesion and outreach. Scientific choice of the speed target value is an important foundation for urban rail transit to give full play to the service functions. In this paper, the relative factors affecting the speed target value are comprehensively analyzed from aspects of function orientation, passenger flow characteristics, time target value and project investment, and the speed target value adapted to the project is proposed.
