Aiming at the urgent requirements of project management from roadway design enterprises, key technologies and application of networked roadway design project management are studied. First, requirements analysis and a general technology scheme are proposed for networked roadway design project management. Next, key technologies are studied systematically, including workflow analysis and improvement, networked and dynamic project monitoring and coordinating, and integrated project information management. Based on the key technologies, an application system of networked roadway design project management is developed and applied in some real projects of roadway engineering design. A case study is presented to illustrate the management process based on the networked project management system. The engineering applications show that the system can effectively improve the management efficiency, reasonably configure and optimize design resource, monitor and coordinate project plan and schedule, and accurately evaluate the performance of design team members.
