Rapid and accurate information sharing is a critical operational need for coping with threats against public transportation systems. This first volume of TCRP Report 86 will be of interest to transit general managers, police and staff in security, operations, communications, information technology, training, and human resources. It will also be of interest to federal, state, and local law enforcement. This volume offers information on a variety of approaches to improving the sharing of threat information. Current practices, operational needs, technologies for threat information dissemination, and system functional requirements are discussed. Effective strategies for sharing analyzed and unanalyzed reports of suspicious activities and a path to an interoperable set of national, regional, and local threat-information forums are proposed.
