Detecting road intersections from gps traces
WebRoad intersection detection is critical to mining road networks from floating car data. A road intersection is a junction where more than two roads meet or cross. Compared with a road segment, intersections are more complex because they may include a left-turn lane, right-turn lane, straight lane, and U-turn lane as represented in Figure 1. To ... WebJan 1, 2012 · Instead of the expense of a complete road survey, GPS trace data can be used to generate entirely new sections of the road map at a fraction of the cost. In cases of existing maps, road map inference may not only help to increase the accuracy of available road maps but may also help to detect new road construction and to make dynamic …

WebNov 4, 2009 · The method begins by smoothing raw GPS traces using a novel aggregation technique. This technique pulls together traces that belong on the same road in response to simulated potential energy wells created around each trace. After the traces are moved in response to the potential fields, they tend to coalesce into smooth paths. WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. As an alternative to expensive road surveys, we are working toward a method to infer the road network from GPS data logged from regular vehicles. One of the most important components of this problem is to find road intersections. We introduce an intersection …
WebJan 11, 2013 · This study proposes a novel method for extracting road intersections from Global Position System (GPS) trace points and for capturing intersections with better … WebSep 14, 2024 · Road intersections are essential to road networks. How to precisely recognize road intersections based on GPS data is still challenging in intelligent transportation systems. Road intersection recognition involves detecting intersections and recognizing its scope. There are few works on intersections’ scope …
WebWe introduce an intersection detector that uses a localized shape descriptor to represent the distribution of GPS traces around a point. A classifier is trained on the shape descriptor to discriminate intersections from non-intersections, and we demonstrate its effectiveness … WebWith more and more vehicles equipped with GPS tracking devices, there is increasing interest in building and updating maps using vehicular GPS traces. But commodity GPS devices have lower accuracy and lower sampling frequency, which made it more difficult to infer road network than most existing approaches that using high-precision and high …
WebSystems and methods for associating vehicle trip data with a base map are provided herein. Systems and methods for providing vehicle trip data showing the greatest usage of routes between an origin and destination are also provided. Systems and methods for predicting a speed limit of a road based on vehicle trip data are also provided.
WebIn literature, intersections are detected mostly using the road users{\textquoteright} turning behaviors. This paper proposes to detect intersections using its definition of connecting at least 3 roads.
