Abstract：The investment measurement of urban rail transit engineering can be roughly divided into three types： the whole line investment measurement， the individual unit investment measurement and the division project investment measurement. Each level of investment measurement has different influencing factors. The relationship among unit， quantity and index of investment measurement is also dynamic. In this paper， the implementation method of urban rail transit project investment estimation based on JAVA Web is expounded. This method realizes the setting of variable sensitive parameters through HTML source code. The server-side code implements two recursive algorithms. The first one deals with the hierarchical relationship of nodes， and the second one implements the complex investment measurement formula. The technical scheme adopted in this paper is cross-platform and can be used to calculate various types of investment in urban rail transit projects.
