Decision makers can use the accumulated shortest paths output to identify the busiest paths to the school. They can use this information to communicate with guardians about the safest routes for their children.

Planners can go a step further by investing in safe infrastructure for the most used paths. For example, planners can identify the busy crossings over highways using the "count" attribute (and visualization) from the query layer and the "highways" attribute from newark_osm.

Of course, communication with stakeholders is ideally a two-way process. To achieve this goal, planners could establish a social networking account, such as a Twitter account, for parents and students to report the problems or features of the walking routes. Planners would likely want to look at this data as well to adjust the safe routes to the problem spots or amenities. This highly simplistic model should be adjusted for the other variables that could also be captured...
