Patent Images
1. A computer-implemented method of creating a virtual traffic network representing traffic conditions on a road system, the method comprising:
- (a) inputting into a processor a base layer comprising map data representing a road system, the road system being defined by a plurality of links and nodes;
(b) the processor creating a traffic layer by combining multiple links and nodes of the base layer into a single link with an upstream node and a downstream node;
(c) inputting into the processor flow data related to traffic flow on the road system and information about traffic events on the road system; and
(d) the processor integrating the base layer, the traffic layer, the flow data and the traffic event information to produce a virtual traffic network representing traffic conditions on the road system, wherein the virtual traffic network indicates both the flow data and the traffic event information.
