Solution Overview
Problem
Automated vehicles face challenges in localizing traffic facilities, especially in construction sites with changed routes and unclear markings, which can be hazardous.
Innovation Solution
A traffic device equipped with a memory and communication interface to store and transmit its position via a wireless communication network, allowing efficient localization of traffic facilities, including area information and semantic data like speed limits and lane curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic facilities rely on physical markings and beacons for route guidance, then vehicles can identify road boundaries, but automated vehicles struggle to localize traffic facilities in construction sites with changed routes and missing markings
Solution Approach 1:
The patent introduces wireless communication as an intermediary between traffic facilities and automated vehicles. Traffic facilities transmit position data via wireless networks (5G, Wi-Fi, Bluetooth) to vehicles, enabling reliable localization without relying on physical markings that may be missing or unclear in construction zones.
Solution Approach 2:
The patent replaces mechanical/visual detection methods (beacons, road markings) with electronic communication systems. Instead of vehicles detecting physical markers, the system uses wireless data transmission to convey position information, eliminating the limitations of visual-based localization.
2Adaptability or versatility
If construction sites use physical barriers and road markings to block areas, then route changes are indicated, but it becomes difficult for automated vehicles to identify the construction site and valid route
Solution Approach 1:
The patent implements preliminary action by having traffic facilities pre-transmit their position data and area information before vehicles arrive. This allows automated vehicles to receive route information in advance and plan their paths through construction zones without relying on real-time visual detection of barriers and markings.
Solution Approach 2:
The patent adds an information dimension to physical barriers by equipping traffic facilities with communication capabilities. Instead of only physical presence, facilities now provide digital information about their position and the areas they protect, creating a multi-layered guidance system that combines physical and informational cues.
3Productivity
If traffic facilities transmit position data remotely via wireless communication, then automated vehicles can efficiently localize traffic facilities, but requires integration of communication interfaces and memory in traffic devices
Solution Approach 1:
The patent applies universality by making traffic facilities multi-functional: they maintain their original physical functions (barriers, markings, beacons) while adding communication functions (wireless transmission, memory storage). This allows existing traffic infrastructure to be enhanced without complete replacement, balancing functionality enhancement with complexity management.
