Risk management for transportation PPP

While providing a variety of advantages when using Public-private partnerships(PPP)for transportation projects,there are also many risks and impediments that can influence dramatically the viability of a PPP project and the relative interest of the public sponsor and the private provider team.In this paper,the major types of risks and their consequences associated with transportation project8 were analyzed in detail.The mitigation strategies for PPP project risks were proposed for overcoming impediments faced by public and private sector partners during contract de- velopment and project implementation phases.Each partner has a level of tolerance for risks and a capacity to manage certain types of risks.Risk transfer to the partner best able to mange it is a way to reduce the cost of the project and improve its potential for success.A risk evaluation model and consistent procedure for assessing the PPP pmject risk are proposed in this paper.
