A navigation system suitable for installation in a host-vehicle includes a navigation-device, a display, and a receiver. The navigation-device is configured to determine a first-location of a host-vehicle. The display is configured to show navigation-information to an operator of the host-vehicle. The navigation-information indicates the first-location relative to a map. The receiver is configured to receive profile-information associated with an other-vehicle. The profile-information includes a second-location of the other-vehicle. The system indicates the second-location on the map.

A system includes a processor configured to determine a navigation instruction execution location within a predefined distance from a vehicle location. The processor is also configured to communicate with a wireless transceiver to receive information identifying an intervening turn-option location, between the execution location and vehicle location. The processor is further configured to determine a distance between the vehicle location and turn-option location and display the determined distance on a navigation display, until the vehicle passes the turn-option location.

A vehicle can be configured to indicate sensor blind spots to a vehicle occupant (e.g., a driver). Using one or more sensors, the vehicle can acquire driving environment data of an external environment of the vehicle. It can be determined whether one or more portions of the acquired driving environment data is unreliable. Responsive to determining that one or more portions of the acquired driving environment data is unreliable, an alert can be caused to be presented within the vehicle. The alert can indicate one or more locations in the external environment in which the driving environment data that is determined to be unreliable. In some instances, the alert can be a visual alert and/or an audial alert.

A method for controlling a motor vehicle may include one or more of the following steps: scanning an environment of the motor vehicle; detecting a passenger transport device stopped in front of the motor vehicle; detecting a movement of at least one person in the vicinity of the passenger transport device; and determining the probability that the passenger transport device will merge into traffic in front of the motor vehicle on the basis of the movement of the person.

A system for simultaneously displaying the locations of all nearby emergency vehicles onto the same moving map as the current location of another vehicle is described. Each emergency vehicle receives location data from a GPS receiver and broadcasts the location data using a Bluetooth or other transmitter. Other vehicles receive location data corresponding to their own locations using their own GPS receivers and each displays their own location onto their own moving map display in the usual manner. Additionally, the other vehicles also have Bluetooth or other receivers which receive the local broadcasts containing emergency vehicle locations and display the locations of all emergency vehicles simultaneously with their own location. The operator of the vehicle benefits by knowing the relative locations of the emergency vehicles when they cannot be seen. Some emergency vehicle operators may optionally choose to not broadcast their location data under certain circumstances.

An enhanced broadcast data service with reports locations of traffic enforcement camera locations (e.g., red light cameras and speed cameras) to users. Traffic enforcement camera information is aggregated, verified (e.g., particularly as to traffic enforcement camera type) and stored (e.g., at a server). A broadcast signal comprising program channels and at least one data channel having traffic enforcement camera information is transmitted to a plurality of receivers. Receivers store at least a subset of the traffic enforcement camera information available from the server and synchronize to it using periodic transmitted updates. Receivers compare receiver location data with stored camera location data, and display or generate audible alerts when the receiver is within a selected geographic range of a traffic enforcement camera. Alerts can be filtered as to camera type. A alerts can employ different color camera icons superimposed on a screen map depending on camera type or whether the camera is newly added.

This disclosure describes an active public transit itinerary system that that utilize digital signals and public transit data to accurately, flexibly, and efficiently monitor client device transit progress across public transit vehicles and generate dynamic public transit interfaces. For example, based on comparing digital signals corresponding to the client device and public transit data, the active public transit itinerary system can determine when a client device is traveling on a public transit vehicle. Furthermore, the disclosed systems can actively generate (and provide for display via public transit graphical user interfaces) alternative public transit itineraries. For example, the disclosed systems can generate a public transit graphical user interface that includes updates to the public transit itinerary (e.g., based on downstream changes to public transit segments) or provides more efficient alternative travel paths to the destination.

Aspects of the disclosure relate providing a lane change notification when a vehicle is to perform a lane change. One or more computing devices may generate and display a video, where the video is generated from a perspective of a virtual camera at a default position and default pitch. The one or more computing devices may receive an indication that the vehicle is to perform a lane change from a first lane to a second lane and adjust, after the vehicle receives the indication, the default position and default pitch of the virtual camera to an updated position further above the vehicle relative to ground than the default position and an updated pitch directed more towards the ground than the default pitch. The video may be generated and displayed from the perspective of the virtual camera at the updated position and updated pitch.
