                National Guidelines for the Network Screening of Collision Prone Locations
**Description:**
        The primary objective of these guidelines is to help practitioners use network screening analytical procedures and statistical concepts to identify and prioritize locations with the highest potential for safety improvement. These guidelines take into consideration each agency’s resource availability. In doing so the guidelines provide:

A source of state-of-the-art network screening methods.
	Guidance for selecting the most efficient method considering the data available.
	Considerations for agencies as they establish the frequency of network screening.The guide presents basic details of the methodology, illustrations, and implementation steps such as the development and/or acquisition of analytical tools. A stepwise process is provided to help users achieve the required level of data capabilities for the development of safety performance functions (SPFs).
While this guide helps agencies to select an appropriate method based on their current resources and screening needs, it also identifies the data and resources that would be required to use the more advanced methods. Fundamentally, this guide recognizes the wide variety of existing data scenarios across agencies and that relatively few agencies have the capability to immediately implement the recommended methods.
