The data also feds into dashboards andd produc informaon portals, enabling travelers to make informed decions about time time and routees routecs.

Incident Detection and Faster Emergency Response

GPS data enables rapid devition of traffic incidents that would otherwise go unnotied until reported. A sudden drop in average speed at a specific location, combined with erratic movement parafarts, can indicate a crash, a stalled vehile, or debris on thee road.
