    "1. A connected vehicle traffic safety system, comprising: at least one roadside unit located at an intersection or near a roadway, the roadside unit comprising at least a processor and a wireless transceiver, the roadside unit configured to transmit wireless signals and receive corresponding responses from a corresponding wireless device of an Onboard Unit (OBU)-equipped vehicle, and to send at least one of vehicle location data, direction heading data, elevation data and speed data from the OBU-equipped vehicle to a traffic signal controller; and a vehicle detection device disposed on or near the roadway on which at least one non-Onboard Unit (OBU)-equipped vehicle is travelling, the vehicle detection device is configured to generate vehicle detection data of the at least one non-Onboard Unit (OBU)-equipped vehicle, wherein the at least one roadside unit is configured to: receive the vehicle detection data of the at least one non-Onboard Unit (OBU)-equipped vehicle to create a proxy data wireless message for the at least one non-Onboard Unit (OBU)-equipped vehicle as if the at least one non-Onboard Unit (OBU)-equipped vehicle is equipped with an Onboard Unit (OBU); and mimic the proxy data wireless message as a first Basic Safety Message (BSM) for the at least one non-Onboard Unit (OBU)-equipped vehicle that would have been available to the Onboard Unit (OBU)-equipped vehicle present nearby to enable the Onboard Unit (OBU)-equipped vehicle equipped with an Onboard Unit (OBU) to be aware of a presence of the at least one non-Onboard Unit (OBU)-equipped vehicle.",
    "2. The system of claim 1, wherein the at least one roadside unit to: blend the proxy data wireless message with a second Basic Safety Message (BSM) of the Onboard Unit (OBU)-equipped vehicle in a connected vehicle system configured for assisting traffic control and generating traffic safety warnings based on the proxy data wireless message and the second Basic Safety Message (BSM), wherein the at least one roadside unit to detect the at least one non-Onboard Unit (OBU)-equipped vehicle based on a signal from the vehicle detection device.",
    "3. The system of claim 2, wherein the at least one roadside unit to: determine a location, a direction heading, an elevation and a speed of the at least one non-Onboard Unit (OBU)-equipped vehicle based on the signal from the vehicle detection device; and create the first Basic Safety Message (BSM) for the at least one non-Onboard Unit (OBU)-equipped vehicle based on the location, the direction heading, the elevation and the speed of the at least one non-Onboard Unit (OBU)-equipped vehicle as the proxy data wireless message.",
    "4. The system of claim 3, wherein the at least one roadside unit to: transmit the proxy data wireless message to the Onboard Unit (OBU)-equipped vehicle present nearby as if the at least one non-Onboard Unit (OBU)-equipped vehicle is equipped with an Onboard Unit (OBU).",
    "5. The system of claim 4, wherein the at least one roadside unit to: generate a first traffic warning for a driver of the Onboard Unit (OBU)-equipped vehicle or a second traffic warning for a vehicle safety system of the Onboard Unit (OBU)-equipped vehicle for initiating an automatic action based on the proxy data wireless message of the at least one non-Onboard Unit (OBU)-equipped vehicle and a Basic Safety Message (BSM) of any Onboard Unit (OBU)-equipped vehicle present nearby.",
    "6. The system of claim 1, wherein the at least one roadside unit to: generate a software message for at least one of a wrong-way violation, a red light signal violation, a train collision warning, a nearest unoccupied parking space and a curve warning."

  "description_excerpt": "1. Field\n\nAspects of the present invention generally relate to connecting vehicular traffic on roadways for generating traffic safety warnings and more specifically relate to creating and blending proxy data for mobile objects having no transmitting devices with data from connected vehicles.\n\n2. Description of the Related Art\n\nConnected vehicles are becoming a reality, which takes driver assistance towards its logical goal: a fully automated network of cars aware of each other and their environment. A connected vehicle system makes mobility safer by connecting cars to everything.\n\nVehicular communications systems are networks in which vehicles, personal mobile devices (Onboard Units or OBUs) and roadside units (RSUs) are the communicating nodes, providing each other with information, such as safety warnings and traffic information. They can be effective in avoiding crashes and traffic congestion. Both types of nodes are generally dedicated short-range communications (DSRC) devices. DSRC works in 5.9 GHz band with bandwidth of 75 MHz and approximate range of 1000 m.\n\nVehicular communications systems are usually developed as a part of intelligent transportation systems (ITS). For example, a Vehicle to Vehicle (V2V) communications system is an automobile technology designed to allow automobiles to “talk” to each other. These systems generally use a region of the 5.9 GHz band set aside by the United States Congress in 1999, the unlicensed frequency also used by Wi-Fi. The V2V communications system is currently in active development by many car makers.",
