Techniques are provided to enable quick previews of what a modified document would look like. In an implementation, a set of page images are stored. Each page image represents a page of a document, the page having been converted to a page image for a first version of the document to permit the document to be viewed in a viewer program. A command is received to modify the document. The requested modification may include, for example, reordering pages, deleting pages, or extracting pages. A preview is generated for a second version of the document. The preview reflects the modification and uses at least one page image from the set of page images created for the first version of the document. Reusing page images allows the preview to be generated very quickly.

Among other things, an equipment for use on board a first ground transportation entity has (a) a receiver for information generated by a sensor of the environment of the first ground transportation entity, (b) a processor, and (c) a memory storing instructions executable by the processor to generate and send safety message information to a second ground transportation entity based on the information generated by the sensor.

Vehicles in traffic are expected to communicate wirelessly, to avoid collisions and facilitate the flow of traffic. Unfortunately, in 5G and 6G, the process of finding a wireless address of a specific vehicle is slow and difficult. Disclosed is a “connectivity matrix”, an emblem that vehicles can display, showing a pattern of black and white squares that forms a unique code. Another vehicle can autonomously read the code and look up the wireless address in a tabulation. The tabulation relates each code to the relevant wireless address, and optionally other information about the vehicle. The two vehicles can then transfer messages, including emergency messages, without delay. At freeway speeds, this can save lives. A central entity maintains the tabulation, ensuring that each wireless address is associated with a unique connectivity matrix code. Roadside companies and access points can also display a connectivity matrix, promote communication with prospective customers.

Aspects of the present disclosure describe systems, methods, and devices for automated vehicular control based on glare detected by an optical system of a vehicle. In some aspects, automated control includes controlling the operation of the vehicle itself, a vehicle subsystem, or a vehicle component based on a level of glare detected. According to some examples, controlling the operation of a vehicle includes instructing an automatically or manually operated vehicle to traverse a selected route based on levels of glare detected or expected along potentials routes to a destination. According to other examples, controlling operation of a vehicle subsystem or a vehicle component includes triggering automated responses by the subsystem or the component based on a level of glare detected or expected. In some additional aspects, glare data is shared between individual vehicles and with a remote data processing system for further analysis and action.

Methods and systems for monitoring use, determining risk, and pricing insurance policies for a vehicle having one or more autonomous or semi-autonomous operation features are provided. According to certain aspects, the operating status and/or configuration of autonomous operation features of an autonomous or semi-autonomous vehicle may be determined, such as via an on-board computer system or mobile device, and/or then directly or indirectly wirelessly communicated via data transmission from the vehicle computer system or mobile device to a remote server. An adjustment to one or more risk levels associated with operation of the autonomous or semi-autonomous vehicle may also be determined, and an auto insurance policy, premium, or discount may be adjusted based upon the adjustment to the risk levels and presented to the customer for their review and approval. As a result, insurance cost savings may be passed onto risk averse customers that opt into to a rewards program.

A method is disclosed for vehicular operation on a road comprising a road network configured to communicate with one or more vehicles on the road, the method comprising sending a signal from a first vehicle to the road network, the signal comprising an intended path of the first vehicle on the road; receiving the signal at the road network; and adjusting at least one of a speed and a path of a second vehicle with respect to the road in response to the signal.

According to one embodiment, a travel control apparatus includes an area setter configured to set a second area on at least one of a plurality of travel paths provided among a plurality of first areas; and a travel controller configured to control timing of a first mobile body to pass through the second area on a travel route of the first mobile body based on passing sequence information on one of the first areas that is located behind the second area, wherein the passing sequence information defines a sequence in which a plurality of mobile bodies including the first mobile body passes through the first area.

A driving assist apparatus including a communication unit and a microprocessor. The microprocessor is configured to perform acquiring traffic light information, position information, and rearward vehicle information including length information of a rearward vehicle, calculating an entire length from a front end of a subject vehicle to a rear end of the rearward vehicle based on the length information, deriving a driving assist information including a target vehicle speed or a target acceleration of the subject vehicle so that a group of vehicles including the subject vehicle and the rearward vehicle passes through a point where a traffic light is provided based on the traffic light information, the position information and the entire length, and transmitting a subject vehicle information indicating that the subject vehicle has a driving assist function capable of deriving the driving assist information to the rearward vehicle through the communication unit.

Provided are a driving negotiation method and apparatus for supporting stability against a blind spot, an unexpected situation, etc. and a rapid judgment and response of an autonomous vehicle in various driving environments. The driving negotiation apparatus includes a wireless communication module configured to support vehicle to everything (V2X) communication and at least one processor connected to the wireless communication module. The at least one processor receives a cooperative request message from a first vehicle, broadcasts a cooperative request message and additional information required for a negotiation to surrounding vehicles, receives a cooperative response message from at least one second vehicle among the surrounding vehicles, and transmits a message indicating that the negotiation is possible or impossible to the first vehicle on the basis of the cooperative response message.

Methods and systems for monitoring use, determining risk, and pricing insurance policies for a vehicle having one or more autonomous or semi-autonomous operation features are provided. According to certain aspects, the operating status of the features, the identity of a vehicle operator, risk levels for operation of the vehicle by the vehicle operator, or damage to the vehicle may be determined based upon sensor or other data. According to further aspects, decisions regarding transferring control between the features and the vehicle operator may be made based upon sensor data and information regarding the vehicle operator. Additional aspects may recommend or install updates to the autonomous operation features based upon determined risk levels. Some aspects may include monitoring transportation infrastructure and communicating information about the infrastructure to vehicles.
