    Abstract: Personal safety concerns for users of vehicles can be indicated, identified, communicated, analyzed, or acted on to make the users and other participants in the technology aware of the safety concerns and to reduce the risks to the users associated with the safety concerns. Personal safety concerns can be recognized based on safety concern triggers. Once recognized, the personal safety concerns can be reported to the users and other participants in the technology by safety alerts. The safety alert can prompt one or more telematics devices at the vehicle to capture, store, or transmit telematics data, including, for example, audio, image, or video data or combinations of them. The captured telematics data can be used to verify the safety alert and the safety concern and present the captured data to a third party participant to enable the third party participant to determine an appropriate response or action.

    Abstract: Among other aspects, information is received at or from a mobile device. The information is derived from one or more position or motion sensors of the mobile device. The derived information is indicative of a position or a velocity of the mobile device. The position or the velocity of the mobile device conforms to a position or a velocity of a vehicle. The derived information is used to identify a dangerous situation involving the vehicle and a person on foot or a bicyclist. A notification is provided of the dangerous situation.

    Abstract: A system for tracking objects includes tracking devices each attached to an object to be tracked and including a short range communications module. A server includes a processor and a memory. A mobile communications device (typically a mobile telephone) includes memory for storing an identification of the mobile device, a long range communication module for communication over a cellular communication network and a short range communications module for receiving short range signals transmitted from tracking devices. The mobile telephone also includes a location determination module to determine the location of the mobile telephone. On receipt of a short range distress signal from a tracking device, a location is obtained from the location module and a signal transmitted to the server including at least the identification of the tracking device, a time of receipt of the short range signal from the tracking device and the determined location of the tracking device when the short range signal was received.

    Abstract: A sensor tag which in use will be affixed to a vehicle for obtaining vehicle telematics data includes a battery for powering the tag and a processor running executable code to process accelerometer data. An accelerometer measures the acceleration of the tag and thereby of the vehicle, and also controls the operation of the processor. A memory is used for storing a unique tag identifier of the tag and for storing trip data including information about trips and acceleration data. Finally, a communication module is used for short range wireless communication with a mobile communications device located in the vehicle via a short range wireless communications protocol, the communication module transmitting the tag's unique identifier and a sequence of time stamped acceleration data. The mobile communications device obtains GPS data, combines this with the acceleration date and transmits this to a server for analysis.

    Abstract: Techniques for measuring extrinsic crash risk are provided. In some examples, a plurality of segments are instantiated in a road segment datastore, with each segment corresponding to a physical road segment in a geographic area and including segment attributes derived from digital map data as well as a risk attribute. From the digital map data, pairs of physical road segments that intersect are determined such that each pair has a corresponding pair of segments in the road segment datastore, and each segment is included in at least one pair. A connection between each segment in each pair is created in the datastore comprising connectivity attributes derived from the digital map data. Based on the segment attributes for a segment, as well as the one or more paired segments and their connectivity attributes, the risk attribute for each segment is updated in the road segment datastore.

    Abstract: Among other things, safety performance of vehicles is monitored or evaluated, or both. Sensor data is received from one or more sensors at a vehicle. One or more risk sources encountered by the vehicle during a period of operation of the vehicle are identified based on the sensor data. One or more safety events experienced by the vehicle during the period of operation are identified based on the sensor data. A risk of a safety event experienced by the vehicle during the period of operation is determined based on the one or more risk sources. A safety performance of the vehicle during the period of the vehicle during the period of operation of the vehicle is determined based on the one or more safety events and the risk.

    Abstract: Apparatuses and methods for determining a route are provided. In some examples, the method comprises: receiving measurements of one or more motion sensors of a mobile device disposed in a vehicle; selecting, based on a start time and an end time of a first route, a subset of the measurements; determining, based on the subset of the measurements, turns or stops made by the vehicle as part of the first route and their directions; determining, based on the subset of the measurements, distances of path segments traveled by the vehicle between the turns or stops; constructing an estimated route including a sequence of the turns or stops and path segments; selecting, based on comparing the estimated route and a plurality of candidates routes from a map, the first route; and displaying the map including the first route.
