This paper presents a study to establish procedures for developing an integrated traffic management plan. The plan aims to: (1) determine reasonable traffic maintenance requirements, to avoid imposing undue constraints on construction or causing excessive traffic delay; and (2) ensure effective use of all existing roadway facilities, by adopting a compatible areawide traffic management plan. Graphs are drawn to demonstrate the relationships between traffic maintenance requirements, project cost and cost to road users. Ten steps for developing an integrated traffic management plan are described. Ten measures are identified, that may be considered in selecting evaluation criteria; they may be classified into: criteria; they may be classified into: (1) traffic impacts; (2) project cost impacts; and (3) environmental concerns. The SATURN (Simulation and Assignment of Traffic in Urban Road Networks) computer model is suitable for performing quantitative analysis of traffic management proposals for a congested network of city streets. Its three main functions are: (1) traffic assignment; (2) traffic simulation; and (3) trip matrix estimation. It is here applied to a case study of the construction of an underground railway station in Taipei, Taiwan.
