Benefits of technology

This approach enables computationally efficient real-time traffic data collection and navigation services for vehicles traveling long distances, reducing computational burdens and enhancing navigation efficiency without the need for extensive sensor installations, thus providing seamless navigation across large territories.

Problems solved by technology

Given the enormous size of a continental roadway system, and the sheer number of roads contained therein, it is impractical not to mention prohibitively expensive to install sensors and / or cameras throughout the network to collect road traffic data for each and every public road on the continent.
However, even though the foregoing technology can, in theory, cover the entire territory of a continent, the sheer number of links and nodes needed to represent all the roadways and intersections in a continental roadway system is so enormously large that it is computationally inefficient to do so.

Embodiment Construction

[0018]By way of general introduction, and as will be elaborated below, an intelligent vehicle highway system collects real-time traffic data and provides processed real-time traffic data to an occupant (e.g. driver) of a vehicle traveling on a continental roadway network or other large-scale roadway network. A digitized continental roadway network represents the continental roadway network using nodes (for intersections or highway exits or entrances) that are interconnected by links (for each direction of each roadway) to thus define a digitized representation of the continental roadway network. To enable intelligent navigation over large expanses of the continental network, which would otherwise be computationally inefficient if the entire continental network had to be loaded, the digitized continental roadway network is partitioned into a plurality of digitized roadway subnetworks. The onboard vehicle navigation device has a processor for executing a software application that inst...

Abstract

An intelligent vehicle highway system collects and provides real-time traffic data to a vehicle traveling on a continental roadway network. A digitized continental roadway network has nodes interconnected by links that define a digitized representation of the continental roadway network. To enable intelligent data collection and navigation over large expanses of the continental network, which would otherwise be computationally onerous, the digitized continental roadway network is partitioned into a plurality of digitized roadway subnetworks. The onboard vehicle navigation device has a processor for executing an application that instantiates a subset of the digitized roadway subnetworks in a vicinity of a current position of the vehicle to collect and provide relevant real-time traffic data to the vehicle in a computationally efficient manner.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is the first application filed for the present invention.TECHNICAL FIELD[0002]The present invention relates, in general, to traffic engineering and, more particularly, to intelligent vehicle highway systems that collect traffic information and provide real-time traffic information to vehicles.BACKGROUND ART[0003]Real-time traffic data collection is of fundamental importance for traffic information management, road guidance, and intelligent vehicle highway systems (IVHS).[0004]Most techniques addressing this issue use static probes, i.e. fixed sensors and / or cameras. Given the enormous size of a continental roadway system, and the sheer number of roads contained therein, it is impractical not to mention prohibitively expensive to install sensors and / or cameras throughout the network to collect road traffic data for each and every public road on the continent.[0005]U.S. Pat. No. 6,401,027 (Xu et al.) entitled “Remote Road Traffic Data ...
