The light curtain defines a first zone and a second zone within the first zone such that detection of the vehicle in the first zone followed by detection of the vehicle in the second zone indicates a correct direction of travel of the vehicle, and detection of the vehicle in the second zone prior to detection of the vehicle in the first zone indicates a wrong direction of travel of the vehicle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle detection system and method","description":"A vehicle detection system includes a sensor mounted to establish a light curtain along a portion of a roadway, and a control unit operatively coupled with the sensor to detect a vehicle on the roadwa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9847022","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.
