Paper, 2009Description: 11 sSubject(s): Bibl.nr: VTI P1835:16 [World]Location: Abstract: In the collection of traffic information, traffic engineers usually use methods with apparatus installed at the roadside. However, by using such methods, it is difficult to collect traffic information simultaneously over a wide area. This paper proposes a method of collecting traffic information simultaneously over a wide area using satellite images. First, the project extracts the road areas from a satellite image using a digital map, and then detects the edges of vehicles on the roads. Then, the project computes the vehicle density from the number of edges on each road.| Current library | Status | |
