The framework identifies a traffic detection area for a roadway at or near the traffic intersection and detects objects in the traffic detection area from sensors located proximate to the roadway. The framework then analyzes sensor data to determine the efficiency of the traffic network and to determine adjustments to timing of various phases of the signal timing plan for the traffic intersection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle queue length and traffic delay measurement using sensor data for traffic management in a transportation network","description":"A framework for precision traffic analysis estimates vehicle queue length at an observed roadway and calculates vehicle delay for improvements in traffic flow efficiency at a corresponding traffic int","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11270581","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.
