摘要：	Many types of sensors are used in managing transportation systems. These sensors supply critical information used by transportation managers for a variety of purposes such as real-time response to changes in travel and traffic conditions, or planning for improvements to the transportation system. In the absence of well developed methodologies to plan the deployment of these sensors, the processes that are used in selection of their location do not always follow a set of criteria that optimize their usefulness. Development of location selection guidelines will assist transportation managers in making the most efficient use of these sensors. This is particularly true in rural areas, given the unique challenges related to topography and remoteness. This report provides an overview of some of the issues and concerns encountered in locating sensors in rural areas that are used for assessment of travel conditions, incident detection, incident verification and collection of planning data. The sensors discussed include road weather information system (RWIS) stations, closed circuit television (CCTV) cameras and inductive loop detectors. Dynamic message signs (DMSs) are also examined as they are commonly co-located with other devices. / Supplementary Notes: Sponsored by California Univ., Berkeley.
