A variety of techniques have been developed to manage incidents efficiently. However, very little guidance exists for agencies wishing to initiate such efforts. This study, which produced two reports (Framework for Developing Incident Management Systems and Development of Incident Management Systems, the Seattle Case Study), serves to provide this guidance by discussing the process of developing and implementing an incident management system. Generally, the process consists of several steps: defining the problem, setting goals and objectives, developing alternatives, evaluating and selecting from those alternatives, implementing, re-evaluating after a specified time, and refining the system. The alternatives that were developed in this document fall under five basic categories, depending on how they benefit incident management efforts. These categories include incident detection, response, site management, clearance, and motorist information. Specific information, including technique description, relative costs and benefits, operational requirements, and funding variations is given for each incident management technique included in these categories. More generally, concerns such as jurisdictional issues, geographical constraints, available resources, operational procedures, training requirements, and administrative coordination are discussed in detail to aid in mitigating difficulties early in the incident management system development process.
