摘要：	This report constitutes a compendium of the results of many years of research at the Texas Transportation Institute working to improve highway/rail intersection safety. Developments over the years of new technologies in sensing, communications, and information presentation offer the opportunity to further improve highway/rail intersection safety beyond current state-of-the-practice. The advent of the Intelligent Transportation System (ITS), formerly referred to as the Intelligent Vehicle-Highway System (IVHS), adds an even broader dimension to transportation management research opportunities at highway/rail intersections. The addition of the highway/rail intersection into the architecture (User Service 30) has led to the preliminary investigation and evaluation of potential ITS applications for rail-related activities. The rail integration activities conducted by the Research Center of Excellence thus far have been focused on providing the information needed to ensure that User Service 30 is an integral component of the National ITS Architecture. A summary of the current information exchange (first generation technology) between highway/rail intersections and traffic signal controllers has been compiled in an effort to provide the concepts associated with current practices. This report also summarizes the second and third generation information-sharing concepts that are currently under development to improve surface transportation management. With advancements in ITS technologies, it is possible to share more information between rail and highway operations to further improve safety and mobility. A review and comparison of the current management concepts associated with intelligent train control and intelligent traffic control was conducted in an attempt to formulate a conceptual ITS structure designed to incorporate rail activities in the surface transportation management network. Further research associated with highway and railroad interaction has the potential to enhance both management activities as well as establish the basis for providing local and advanced traveler information exchange.
