This study establishes an evaluation framework for assessing Intelligent Transport System (ITS) benefits including those enjoyed by travelers, ITS service providers, and society. It also calculates the traveler benefits, for which in principle the facility users will pay. The data on Willingness to Pay (WTP) is obtained from a Stated Preference (SP) survey, of 1,357 Shanghai motorway users through a web based survey combined with face to face interviews, in 2007. This research aims to measure the consumer surplus from ITS consumption and to form a greater understanding of the positiveexternalities in ITS provision. Choice models have been estimated for WTP of travelers for better quality services that would be received from three types of ITS system. The motorway travel attitudes and behavior variables within the survey relate to the purpose of the journey, toll payer, travel cost, and travel time. Respondents were grouped into five types of drivers, further sub-divided by trip purpose and who pays the toll. The results indicate that the traveler benefits of high quality services motivate motorway travelers to pay for certain ITS services; the value of the three systems vary for different types of drivers. In addition, the values of some ITS services obtained through stated choices are not fully consistent with initial attitudes. The results may now be used to guide government policy decisions to determine reasonable benchmarks and/or subsidy levels when developing effective Public Private Partnership (PPP) schemes.
