One or more techniques and/or systems are provided for providing a traffic news interface. For example, a traffic news provider component may query traffic camera data and/or traffic incident data to identify traffic cameras and/or traffic incidents along a route of a driver. The traffic cameras and/or the traffic incidents may be ranked based upon a safety metric, a travel time sensitivity metric, an alternative route selection metric, a driving behavior pattern, a driver mood, a distance of a traffic camera or traffic incident from a current user location, and/or other information used to determine how relevant information from the traffic camera and/or a traffic incident is to this particular driver. A subset of traffic cameras and/or traffic incidents may be selected for inclusion within a traffic news interface based upon camera relevancy rankings and/or incident relevancy rankings.

Transit through an area by a population of travelers may be evaluated by a number of techniques, and may be useful for routing, transit time estimation, and transit control. Some techniques involve the use of probes, such as individuals or vehicles that are tagged and trackable through the area. However, estimating properties such as transit queue volume through probe counts may be difficult, as the ratio of probes to the overall population may vary. Presented herein are techniques for estimating transit properties by evaluating transit queues to estimate the probe ratio for an area. Such techniques involve counting and tracking the probes in a transit queue to estimate a queue length change of the transit queue, and a probe rate change of probes entering and exiting the transit queue. This information may inform estimates of the probe ratio, and in turn regional transit estimates, such as transit queue volumes.

Users who are traveling on a path between a first location and a second location may be informed by navigation devices about the user's selected route. The path may also feature two or more lanes, which may present comparative advantages (e.g., a toll-restricted lane may present less traffic, and a toll-free lane may present more traffic at a reduced cost). Presented herein are techniques for enabling navigation devices to advise users about the lanes of the path. A travel service may collect information about the respective lanes, such as traffic density and the typical travel duration of users utilizing the lane during various periods, and may transmit information about the predicted travel durations of the respective lanes to the device. Such information may enable the device to advise the user to choose a selected lane, according to the predicted travel durations of the lanes of the path.

A user driving a vehicle may be monitored by a device on behalf of a third party, such as employers and insurers. The device may generate an objective evidentiary record of the user's driving safety and/or proficiency for use by the third party. The user may wish to share the evidentiary record with other parties, but the third party that controls the record may not agree and/or release the record. A user-generated record of the user's driving behavior may be untrustworthy and/or unverifiable. Instead, a device of the user monitors the operation of the vehicle by the user, generates a driving profile of the user's driving behavior and risk rating, and cryptographically signs the driving profile. The cryptographically signed driving profile is transmitted to the user for sharing with third parties, e.g., potential employers and insurers, and the authenticity of the driving profile is verifiable using the cryptographic signature.

One or more techniques and/or systems are provided for selectively collecting vehicle telemetry data from one or more vehicles. For example, a communication data budget for a vehicle may be identified (e.g., a 5GB per month data connection plan). A determination may be made as to whether the vehicle can provide vehicle telemetry data used to model a travel condition (e.g., road imagery, temperature, a windshield wiper state, and/or other vehicle telemetry data used to model a road safety condition). If the vehicle has remaining communication data budget available for transmission of the vehicle telemetry data without the vehicle exceeding the communication data budget for a billing cycle, then a data request for the vehicle telemetry data may be sent to the vehicle. Responsive to receiving the vehicle telemetry data from the vehicle, the travel condition may be modeled (e.g., the road condition may be determined as icy).

One or more techniques and/or systems are provided for training and/or utilizing a traffic obstruction identification model for identifying traffic obstructions based upon vehicle location point data. For example, a training dataset, comprising sample vehicle location points (e.g., global positioning system location points of vehicles) and traffic obstruction identification labels (e.g., locations of known traffic obstructions such as stop signs, crosswalks, stop lights, etc.), may be evaluated to extract a set of training features indicative of traffic flow patterns. The set of training features and the traffic obstruction identification labels may be used to train a traffic obstruction identification model to create a trained traffic obstruction identification model. The trained traffic obstruction identification model may be used to determine whether a road segment has a traffic obstruction or not.
摘要:
Ein System zur Bereitstellung von Daten für Fahrzeuge umfasst einen Gebietsbereichsserver (BS1) zum Bereitstellen von Informationsdaten für Fahrzeuge (F1, F2) in einem Gebietsbereich (GB1). Ein erstes und zweites der Fahrzeuge (F1, F2) prognostizieren Wegedaten (PW1, PW2), die mindestens einen Fahrweg angeben, den das erste und zweite Fahrzeug (F1, F2) mit einer Wahrscheinlichkeit fahren werden. Das erste und zweite Fahrzeug (F1, F2) sind bei dem Gebietsbereichsserver (BS1) registriert sind, wenn der jeweils durch die prognostizierten Wegedaten (PW1, PW2) angegebene Fahrweg des ersten und zweiten Fahrzeugs (F1, F2) in dem Gebietsbereich (GB1) liegen. Der Gebietsbereichsserver (BS1) erzeugt in Abhängigkeit von empfangenen Sensordaten des ersten Fahrzeugs (F1) die Informationsdaten zu erzeugen. Die erzeugten Informationsdaten werden von dem Gebietsbereichsserver (BS1) zu dem zweiten Fahrzeug (F2) gesendet, wenn sich die prognostizierten Wegedaten (PW2) des zweiten Fahrzeugs (F2) mit den prognostizierten Wegedaten (PW1) des ersten Fahrzeugs (F1) überlappen und das zweite Fahrzeug (F2) bei dem Gebietsbereichsserver (BS1) registriert ist.

Systems, methods, apparatuses, and computer-readable media for are provided for providing a navigation route based on network availability. In one embodiment, a method includes receiving a request for a navigation route. The method may further include providing the navigation route, the navigation route taking into account accessibility information relating to accessibility of at least one wireless network at different geographic locations along the navigation route and device specific information relating to attributes of a mobile device. The accessibility information may include data collected by different mobile devices at different geographic locations. The accessibility information may also be stored at a centralized server.
