摘要：	Active Traffic Management (ATM) applications, such as variable speed limits, queue warning systems, and dynamic ramp metering, have been shown to offer mobility and safety benefits. Yet because they differ from conventional capacity investments in terms of cost, service life, and operating requirements, how to incorporate them into the planning process is not clear. To facilitate such incorporation, this study developed guidelines for considering ATM deployments. The guidelines consist of four sets. The first set identifies required infrastructure and operational conditions, such as sensor placement and queuing behavior, to apply a particular ATM technique at a given site. The second set presents sketch planning analysis methods to estimate the operational and safety benefits of applying the particular technique at the site; these may be refined with the third set concerning a more detailed (and accurate) simulation analysis. The fourth set concerns continued monitoring of an ATM deployment at a given site. Also provided is a framework for incorporating ATM concepts into the regional planning process. The framework is illustrated with a hypothetical case study of variable speed limits implemented on I-66 in Virginia.
