Real‑time probe data highlighted as critical tool for evacuation planning and operations

INRIX and consultants told commissioners that probe data — anonymized location pings from phones, vehicles and fleet telematics — can provide near‑real‑time visibility into road closures, speed drops and routing choices during disasters.

“Without real time visibility into where people are coming and going… puts lives at risk,” Ahmed Durat, chief product officer at INRIX, said while walking through examples from Western Washington floods, Southern California wildfires and a Hawaii tsunami response. INRIX showed how a sudden disappearance of green speed traces and the appearance of widespread red/stop indicators on a timeline corresponded to an impassable flooded segment in the Fall City area.

Consultants from Farrin Piers and partners outlined planning and modeling approaches agencies can adopt: dynamic traffic assignment, traveler segmentation and scenario‑based signal and lane strategies. They also stressed integrative public‑information tools — real‑time dashboards, geofenced help alerts and coordinated operational centers — so agencies can verify closures and push targeted messages to people in harm’s way. Commissioners were urged to build operational pilots and interagency dashboards to improve evacuation response.
