Field Investigation Form
The selection tool within PEDSAFE requires a number of inputs describing the geometrics and operations of the location in question. The system uses these inputs to refine the selection of applicable countermeasures. Included on this page is a form that may be used in the field to acquire these data elements.

Notes: * Use 85th percentile speed if available. If not available, add 9 mi/h to the posted speed limit as a surrogate measure for the 85th percentile speed. Prior research has shown that 85th percentile speeds for vehicle traveling on many urban and suburban streets (including arterial, collector, and local classifications) generally exceed the posted limit by 6 to 14 mi/h.
