A remote system in one embodiment is a Bluetooth enhanced traffic controller. Characteristics of Bluetooth technology, such as a unique address for each Bluetooth capable device are used to detect a vehicle with a Bluetooth device by at least a first and a second remote system. Vehicle identifying data including at least a time stamp is transmitted by the remote systems to a central system. The central system determines a travel time, or an estimated travel delay. Travel time related data is provided by the central system to a display, such as a variable or dynamic message sign."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Estimation of travel times using bluetooth","description":"Methods for estimating travel time using at least two remote systems to record the timestamps associated with obtaining identifying information of a wireless Bluetooth enabled, or other WPAN technolog","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8519868","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.
