Abstract
In an example, a roadside device is disclosed. In one or more implementations, the roadside device includes a deviation determination module that is configured to determine a difference between a determined current position of the roadside device and a predefined position of the roadside device. The roadside device also includes a modification module that is configured to modify geometry data representing an intersection environment based upon the difference, and a vehicle-to-everything (V2X) communication module that is configured to broadcast the modified geometry data within the intersection environment.
Claims23
A roadside device comprising:
- a position determining module that is configured to determine a current position of the roadside device based on signals received from Global Navigation Satellite System satellites;
- a deviation determination module that is configured to compare the determined current position of the roadside device with a predefined position of the roadside device to determine a differential vector representing a difference between the determined current position of the roadside device and the predefined position of the roadside device;
- a modification module that is configured to modify geometry data that includes position coordinates of an intersection environment to generate modified position coordinates of the intersection environment according to the differential vector;
- and
- a vehicle-to-everything (V2X) communication module that is configured to broadcast the modified position coordinates of the intersection environment to at least one vehicle within the intersection environment.

A system comprising:
- a roadside device configured to be positioned proximate to a signalized intersection, the roadside device including:
- a position determining module that is configured to determine a current position of the roadside device based on signals received from Global Navigation Satellite System satellites;
- a deviation determination module that is configured to compare the determined current position of the roadside device with a predefined position of the roadside device to determine a differential vector representing a difference between the determined current position of the roadside device and the predefined position of the roadside device;
- a modification module that is configured to modify geometry data that includes position coordinates of a signalized intersection to generate modified position coordinates of the signalized intersection according to the differential vector;
- and
- a vehicle-to-everything (V2X) communication module that is configured to broadcast the modified position coordinates of the signalized intersection to at least one vehicle within the signalized intersection,
- wherein the modified position coordinates of the signalized intersection are received by a vehicle-to-everything (V2X) communication module of the at least one vehicle.
