Abstract

Disclosed are systems and methods relating to defining a road network used by vehicles for movement and/or parking. A classifier may be employed for identifying portions of the road network via machine learning techniques and processing of historical telematic data.

First claim

What is claimed is:

1. An intelligent telematics system comprising a plurality of monitoring devices, a first datastore, a processing resource and a network interface configured to communicatively couple the plurality of monitoring devices to the first datastore, the intelligent telematics system configured for:
transmitting raw vehicle data indicative of vehicle operating conditions from the plurality of monitoring devices;
over a period of time, receiving the raw vehicle data and storing the raw data in the first datastore to form second historical vehicle data;

partitioning a road network area into a plurality of contiguous second subzones for defining a road network zone;
selecting vehicle data indicative of vehicle operating conditions for a plurality of vehicles corresponding to the road network zone;

for each of the plurality of contiguous second subzones, generating a plurality of features based on the vehicle data;
generating unlabelled data includes the plurality of features for each of the plurality of contiguous second subzones;
processing the unlabelled data by a classifier generated using at least one machine learning technique for classifying each second subzone of the plurality of contiguous second subzones as one of a portion of a vehicle way and not a portion of a vehicle way;
forming classification data indicative of a classification of each of the plurality of contiguous second subzones;
processing the classification data for determining a geographic location of the road network; and
defining the road network includes generating data indicative of the geographic location of the road network.

2. The intelligent telematics system of claim 1 , further comprising a first data management system including the first data store and configured for transmitting, over the period of time, the raw vehicle data from the plurality of monitoring devices to the first data management system to form the second historical vehicle data.

13. The intelligent telematics system of claim 1 , wherein classifier data associated with the classifier configured to define dimensions of each of the plurality of contiguous second subzones.

14. The intelligent telematics system of claim 1 , wherein the intelligent telematics system configured for partitioning a road network area into a plurality of contiguous second subzones for defining a road network zone comprises the intelligent telematics system configured for partitioning the road network area into a plurality of contiguous second subzones according to a Geohash indexing system.

15. The intelligent telematics system of claim 14 , wherein classifier data associated with the classifier defines a precision of Geohashes of the Geohash indexing system.

16. The intelligent telematics system of claim 1 , wherein the intelligent telematics system configured for selecting vehicle data indicative of vehicle operating conditions for a plurality of vehicles corresponding to the road network zone includes the intelligent telematics system configured for selecting raw vehicle data from second historical data corresponding to the road network zone.
