A comprehensive assessment enhances crash-related data and provides additional information regarding community resources (those a community already has and those a community is missing) and community attitudes toward a project. The assessment is also used to identify gaps, duplication, and potential solutions or countermeasures. Information gained in a thorough assessment makes it possible to develop an action plan that best meets the needs of the community. The assessment may also identify a shortage of certain resources or technical support that may be available through a traffic safety grant with federal or state funding. In this regard, information gathered during the needs assessment will be helpful when developing a project proposal.

A community needs assessment can provide opportunities beyond problem identification. A good assessment may also be used to gain commitment for a project with sources of potential funding, with the community itself, and with a sponsoring agency. Besides assessing current resources, the process may also provide building blocks for self-sufficiency and can be useful in addressing task forces, community officials, and traffic safety committees.
