Abstract
To address the limitations of conventional navigation systems in dynamic environments, this disclosure presents a system for improving location accuracy and providing real-time data to users. This disclosure describes equipping public infrastructure, such as traffic lights, pedestrian crosswalks, railroad crossings, and other roadside units (RSUs), with low-cost wireless beacons or local transmitters (e.g., Bluetooth, Ultra-Wideband, RFID, etc.). These transmitters continuously broadcast or advertise valuable information, like traffic signal timing, status updates, or precise location data. A user's computing device—which could be a smartphone, wearable, or an in-vehicle system within a connected or autonomous vehicle—may then receive these signals as it approaches. Such a direct vehicle-to-infrastructure (V2I) or device-to-infrastructure communication may enable applications, such as a mapping program or an advanced driver-assistance system (ADAS), to provide context-aware alerts like a countdown to a green light. Furthermore, by receiving signals from these fixed, known locations, the device can augment or correct its Global Navigation Satellite System (GNSS) or GPS position, enabling hyper-accurate localization, especially in challenging environments like dense 'urban canyons.'
