Abstract: A building occupant tracker for tracking the location of an occupant in a building by tracking a smart device associated with the occupant at a location server.

Abstract: A connected traffic monitoring system comprises at least one Roadside Unit (RSU) and a traffic signal controller. The roadside unit is configured to transmit wireless signals, receive corresponding responses from a first Onboard Unit (OBU)-equipped vehicle and a second OBU-equipped vehicle and send data from the first OBU-equipped vehicle and the second OBU-equipped vehicle to the traffic signal controller. The traffic signal controller to calculate a distance between the first Onboard Unit (OBU)-equipped vehicle and the second OBU-equipped vehicle in a vehicle queue associated with a traffic light signal on an intersection, determine the queue length of the vehicle queue, determine whether the distance between the first OBU-equipped vehicle and the second OBU-equipped vehicle is greater than a vehicle length and if the distance is determined greater than the vehicle length, detect at least one non-OBU-equipped vehicle stopped in the vehicle queue behind the first OBU-equipped vehicle.

Abstract: A connected traffic safety system comprises at least one roadside unit and a vehicle detection device. The roadside unit is 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. The vehicle detection device is configured to generate vehicle detection data of at least one non-Onboard Unit (OBU)-equipped vehicle. The roadside unit to receive the vehicle detection data for creating a proxy data wireless message for the non-Onboard Unit (OBU)-equipped vehicle. The roadside unit to mimic the proxy data wireless message as a first Basic Safety Message (BSM) for the non-Onboard Unit (OBU)-equipped vehicle that would have been available to the Onboard Unit (OBU)-equipped vehicle present nearby.

Abstract: Embodiments include an emergency traffic management system includes a traffic management center configured to receive traffic information, a traffic signal controller in communication with the traffic management center, and roadside equipment in communication with the traffic signal controller. The roadside equipment includes a transceiver configured to communicate with one or more mobile devices via a wireless communications channel, a memory device configured to store emergency information, a processor configured to provide the emergency information to the one or more mobile devices via the transceiver, and a power supply configured to provide power to the processor and the transceiver.

Abstract: A roadside equipment (RSE) system that can be used for controlling traffic signals and other equipment and corresponding method. A method includes maintaining a traffic signal in a GREEN phase in a first direction, including displaying a GREEN indicator in the first direction. The method includes detecting an event indicating that the phase of the traffic signal in the first direction should be changed and changing the phase of the traffic signal to a pre-YELLOW phase in response to the detected event, including continuing to display the GREEN indicator in the first direction. The method includes wirelessly transmitting a message indicating the pre-YELLOW phase and a phase time, the phase time indicating a next change of phase of the traffic signal, and changing the phase of the traffic signal to a YELLOW phase when the phase time has been reached.

Abstract: Methods for estimating travel time using at least two remote systems to record the timestamps associated with obtaining identifying information of a wireless Bluetooth enabled, or other WPAN technology, electronic device in a vehicle. A remote system in one embodiment is a Bluetooth enhanced traffic controller. Characteristics of Bluetooth technology, such as a unique address for each Bluetooth capable device are used to detect a vehicle with a Bluetooth device by at least a first and a second remote system. Vehicle identifying data including at least a time stamp is transmitted by the remote systems to a central system. The central system determines a travel time, or an estimated travel delay. Travel time related data is provided by the central system to a display, such as a variable or dynamic message sign.

Abstract: A roadside equipment (RSE) system that can be used for controlling traffic signals and other equipment and corresponding method. A method includes wirelessly receiving vehicle data from an onboard equipment (OBE) system connected to a vehicle, the vehicle data including location data, time data, and vehicle identification data related to the vehicle. The method includes determining motion data for the vehicle and determining the current state of at least one traffic device. The method includes determining a roadway lane corresponding to the vehicle, based on the motion data and the current state of the at least one traffic device, and storing the vehicle and associated roadway lane.

Abstract: A roadside equipment (RSE) system that can be used for controlling traffic signals and other equipment and corresponding method. A method includes wirelessly receiving vehicle data by an RSE system and from an onboard equipment (OBE) system connected to a vehicle. The vehicle data includes location data, time data, and vehicle identification data related to the vehicle.
