WebJan 1, 2004 · Abstract. In practice, partial floating car runs (runs in the direction of the traffic flow of interest) plus a measured or assumed controlling bottleneck capacity could be used to estimate the total travel time delay along a freeway segment. The floating car's travel time in excess of that of user-specifiedfree flow travel is defined as the ... WebDec 16, 2015 · Fortunately, floating car, namely Global Position System (GPS)-equipped taxi, is an effective way to collect the real-time traffic data in a large-scale road network [ 3 ]. In addition, these ubiquitous mobile sensors have lower cost than the fixed sensors which collect data at fixed trunks or major intersections.

WebJun 24, 2024 · “Floating car data (FCD), also known as floating cellular data, is a method to determine the traffic speed on the road network. It is based on the collection of localization data, speed, the direction of travel and time information from mobile phones in vehicles that are being driven. WebSep 22, 2011 · In addition, the paper presents a novel technique for traffic data collection named Floating Car Observer (FCO). Thereby, the speeds of oncoming vehicles are measured from a moving vehicle... taslim olawale elias
