Claim 0:
1. A method for identifying connected and non-connected road users at a site on a road network, for traffic control, the method comprising:
receiving at a processing unit sensor data informative of road users at the site and processing the sensor data to detect road users, wherein the sensor data is received from one or more sensors located externally to the road users;
receiving at the processing unit V2X communications comprising data informative of connected road users;
using the sensor data to obtain user parameters of all detected road users to yield a sensor data-based plurality of all detected road users characterized by respective sensor-based user parameters, wherein said sensor-based user parameters include location and at least one of speed, acceleration, bearing, classification, past trajectory and predicted trajectory, and wherein the sensor data-based plurality of all detected users comprises connected road users and non-connected road users;
using the data comprised in the received V2X communications to obtain V2X-based parameters of connected road users to yield a V2X communications-based plurality of connected road users characterized by respective V2X-based parameters, wherein said V2X-based parameters include location and at least one of speed, acceleration, bearing, classification, past trajectory and predicted trajectory;
matching between data in the sensor data-based plurality of all detected road users and in the V2X communications-based plurality of connected road users to identify unmatched road users as non-connected and matched road users as connected, wherein the matching comprises defining similarities between respective sensor-based location and V2X-based location and between at least one corresponding other pair of sensor-based and V2X-based parameters, and wherein a match is found when the defined similarities exceed respective thresholds and is not found when the defined similarities are less than respective thresholds;
creating a virtual map comprising the locations of the connected and non-connected road users; and
generating a signal to control a device based on the virtual map.
