Techniques are described herein for facilitating V2X communications using a connected vehicle platform. The techniques include receiving, from an onboard diagnostics (OBD) accessory device, a vehicle report comprising vehicle data of a vehicle equipped with the OBD accessory device, the vehicle located at a target location. An additional vehicle located within a predetermined distance of the target location is identified. The additional vehicle is equipped with an onboard diagnostics unit (OBU). A traffic advisory message is generated based at least on the vehicle data in the vehicle report. Thereafter, the techniques include determining whether the additional vehicle is located within a communication range of the vehicle and in response to making a determination that the additional vehicle is located outside of the communication range of the vehicle, the traffic advisory message is broadcasted to the OBU of the additional vehicle.
