GENERATING INTERSECTION DATA

摘要

A method of generating data in relation to one or more intersections in a geographic area involves obtaining positional data relating to the movement of a plurality of devices with respect to time in the area. For one or more particular manoeuvres at the or each said intersection, the method comprises filtering the positional data to obtain positional data relating to the movement of devices performing the particular manoeuvre at the intersection, and analysing the positional data to obtain a free flow time indicative of the time taken to perform the given manoeuvre under free flow traffic conditions, and a set of one or more time delays for the given manoeuvre. The or each time delay is in respect of a given time period, wherein the or each time delay is indicative of the time delay incurred when performing the manoeuvre in the respective time period with respect to the free flow time. The method further comprises storing data indicative of the or each time delay in association with data indicative of the manoeuvre, the intersection and the time period to which it relates.
