A central system is configured to charge a pollution fee to a vehicle (10) moving in the pollution zone when the air pollution exceeds a threshold value. Different vehicles are charged different fees, e.g. based on their function and emission. A variable message sign (240) warns of the increased fees, so most private cars choose alternative routes (232, 233) around the pollution zone (222, 223), but allow motorists willing to pay a substantial pollution fee to use route (231). Heavy diesel vehicles may be exempt from pollution fees along a direct route (231) through the pollution zone to keep them away from small roads and residential areas. A method using mobile devices for registering passengers for a passenger discount is also described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Present invention concerns a system for controlling traffic","description":"A system (200) for controlling road traffic comprises measurement station (210) for determining air pollution in an urban area comprising pollution zones (221-223) with predetermined geographical boun","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11276253","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.
