The Network Screening application is designed to help users rank their entire roadway network in an easy-to-use interface. The Network Screening application has 5 key features: Attribute Search, Segment Flyout, Roadway Ranking, Contextual Data, and the Network Screening report. Each feature is discussed in more detail below.
Use Numetric’s powerful text-to-search feature to run custom roadway network screening requests. Search by recommended countermeasure, crash type, or any other crash or roadway attribute, and generate instant roadway rankings that tell you which roadways require your attention.

Clicking on any segment in your network displays the Segment flyout, which contains current, and historical segment rankings, crashes by milepoint, a summary of crash statistics (including number of crashes and fatal (critical) crashes, crash ratio, crash rate, crashes per mile, and location information), a summary of roadway details (including AADT, function classes, and any other roadway datapoint present in your data), and a list of recommended countermeasures for that segment.
(The Segment Flyout illustrating the segment rank crashes by milepoint, the summary, and part of the roadway details section.)
Rank your selected roadway by crashes, fatalities, crash ratio, crash rate, or crashes per mile, and see instant ranking results.
(The network ranking table. Users can sort and rank their network by any listed column of data.)
With photos and Google Streetview, users can explore selected segments, and even see how each segment has changed over time, all without leaving the app.
Network Screening Report
Generate a downloadable network screening report which contains the network ranking, and a breakdown of each segment, including the crash rate, crash ratio, crashes per mile, fatality rate, and serious rate, as well as a stacked bar chart indicating the mile point at which the crashes occurred.
Network Screening Intersections
Network Screening Intersections is built inside the Network Screening application and provides metrics based on the HSM and Access Management Manuals. The user interface matches Network Screening, with the only difference being the mathematics for creating the crash rates for intersections.
