## Abstract

In an approach for notifying, a computer receives one or more preemption notifications, wherein the one or more preemption notifications are associated with one or more priority vehicles. The computer identifies a device that is within range of the received one or more preemption notifications, wherein the device includes one or more directional indicators. The computer one or more directions of approach associated with the received one or more preemption notifications relative to the identified device. The computer determines a number of approaching priority vehicles associated with each instance of the identified one or more directions of approach relative to the identified device. The computer initiates to display through the one or more directional indicators of the identified device the identified total number of approaching priority vehicles associated with the one or more identified directions of approach relative to the identified device.

## Claims

### Claim 1

A computer program product for notifying, the computer program product comprising:
one or more non-transitory computer readable storage media and program instructions stored on the one or more non-transitory computer readable storage media, the program instructions comprising:
program instructions to receive one or more preemption notifications, wherein the one or more preemption notifications are associated with one or more priority vehicles;
program instructions to identify a traffic light, a pedestrian signal, a railroad crossing signal, a light rail transit crossing signal, and an in-vehicle information system that are within range of the received one or more preemption notifications, wherein the in-vehicle information system includes a heads up display, a vehicle representation, a dashboard gauge, a global positioning system, a rear view mirror indicator, a side view mirror indicator, a video display, and an audio messaging system, wherein the traffic light, the pedestrian signal, the railroad crossing signal, the light rail transit crossing signal, and the in-vehicle information system include one or more directional indicators that include lights in a compass orientation, icons, symbols, text messages, audio notifications, and tactile notifications, wherein the compass orientation is a set of defined points that represent a direction as viewable by pedestrians and drivers, wherein the defined set of points identify a front direction, a right direction, a rear direction, and a left direction;
program instructions to identify one or more directions of approach associated with the received one or more preemption notifications relative to the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system based on: GPS information within the received one or more preemption notifications, triangulation of the received one or more preemption notifications, and image processing of camera data associated with the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system;
program instructions to identify an orientation of the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system;
program instructions to identify one or more directions of approach associated with the received one or more preemption notifications relative to the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system with respect to the identified orientation of the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system;
program instructions to determine a number of approaching priority vehicles associated with each instance of the identified one or more directions of approach relative to the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system;
program instructions to initiate to display through the one or more directional indicators of the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system, the identified total number of approaching priority vehicles associated with the one or more identified directions of approach relative to the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system;
program instructions to determine whether the received one or more preemption notifications ceases based on the GPS information within the received one or more preemption notifications, the triangulation of the received one or more preemption notifications, and the image processing of the camera data associated with the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system; and
responsive to determining that the received one or more preemption notifications cease, program instructions to initiate to stop display through the one or more directional indicators of the identified traffic light, the identified pedestrian signal, the identified railroad crossing signal, the identified light rail transit crossing signal, and the identified in-vehicle information system.
