Acquisition of the field measurement data relating to lane change actions

Abstract

As a data set for validation of microscopic simulation models, we obtained the fundamental diagram (°ux versus density relation), and the relations of velocity versus density, lane usage ratio versus density and lane-changing frequency versus density derived from a single¯eld measurement campaign held at a Japanese urban expressway. The results were drawn from image analysis of video camera data obtained at the site.

Grassmann Manifold Based State Analysis Method of Traffic Surveillance Video

“…TSV data can be used to extract massive amounts of meaningful traffic information including traffic density, average velocity of vehicles, traffic flux, lane-changing rate and other various statistical properties for traffic flow. In fact, there are some pioneer studies [2,3] that obtain those properties from traffic videos, which can be applied to validate mathematical models of traffic flow.…”
