The present disclosure can remarkably enhance a capability of protecting privacy of vehicle data, ensure rapid and accurate data processing, reduce energy consumed for urban traffic estimation, and shorten required traffic estimation time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Realtime urban traffic status monitoring method based on privacy-preserving compressive sensing","description":"The present disclosure relates to a realtime urban traffic status monitoring method based on privacy-preserving compressive sensing, including the following steps: step S1: dividing vehicle data under","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11303620","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
