A controller is configured to acquire primary information indicating that an emergency vehicle during emergency driving has satisfied the condition that the emergency vehicle has entered a particular area in which right of way may be given and/or the condition that the emergency vehicle has shifted into a specific driving mode in which right of way may be given within the particular area. Upon acquisition of the primary information, the controller stops a siren of the emergency vehicle or reduces the volume of the siren of the emergency vehicle.

Disclosed is a device for identifying sirens of priority vehicles and for warning a hearing-impaired driver of a motor vehicle of a presence of at least one priority vehicle in an environment of his vehicle, including at least one sound receiver, a computing unit for analyzing the audio recording and a unit for comparing the frequencies of the audio recording with frequencies previously stored in storage of the computing unit as being associated with a siren of a given priority vehicle, and for doing so for each type of priority vehicle, and at least one visual and/or vibratory element for warning the driver when a presence of a priority vehicle is detected in an environment of the motor vehicle.

Systems and methods are disclosed for determining, and displaying, the regulatory compliance status of a motorized vehicle, a driver of a motorized vehicle, or a non-vehicle machine. An authorized agent, such as a law enforcement officer, can perform a remotely-initiated safe stop of a motorized vehicle to prevent a high-speed chase. A system management center can receive, store, and transmit regulatory compliance records indicating the regulatory compliance status of drivers, motorized vehicles, and non-vehicle machines. A motorized vehicle can detect, and report, a driver “tail-gating” the motorized vehicle. The regulatory compliance history of drivers, motorized vehicles, and non-vehicle machines can be queried by authorized users.

Methods and apparatuses are provided for use in wireless communication devices to provide a capability for vehicles to actively perform traffic planning with regard to other vehicles, for example, within a region comprising an intersection and possibly wherein the intersection is not associated with a device or service for such or similar purposes. Such underlying techniques may reduce traffic congestion in certain instances by allowing two or more vehicles to negotiate or otherwise coordinate safe traversal within a region comprising an intersection. Moreover, the traffic planning techniques may be of use for a variety and/or mixture of different types of vehicles, paths, intersections, etc.

The present disclosure generally relates to generating emergency vehicle warnings, automatic control of autonomous vehicles based upon the emergency vehicle warnings. More particularly, the present disclosure relates to generating data representative of emergency vehicle warnings and alternate autonomous vehicle routing based upon real-time information related to an emergency vehicle. The information related to the emergency vehicle may include emergency vehicle origination location data, emergency vehicle current location data, emergency vehicle route data, and/or emergency vehicle destination location data. An emergency vehicle warning and/or alternate vehicle routing for autonomous vehicles may be generated based further on information related to an autonomous vehicle. In one aspect, an emergency vehicle may wirelessly communicate with the autonomous vehicle and/or an insurance provider remote server. The insurance provider may adjust auto insurance for insured individuals, having vehicles with the vehicle safety functionality discussed herein, to reflect lower risk and provide insurance savings to customers.

A method detects presence of a multi-tone siren type in an acoustic signal. The multi-tone siren type is associated with one or more siren patterns, where each siren pattern includes a number of time patterns at corresponding frequencies. The method includes processing a number of frequency components of a frequency domain representation of the acoustic signal over time to determine a corresponding plurality of values. That processing includes determining, for each frequency component, a value characterizing a presence of a time pattern associated with at least one siren pattern. The method also includes processing the values according to the siren patterns to determine a detection result indicating whether the multi-tone siren type is present in the acoustic signal.
