Abstract
An emergency passage system facilitates movement of an emergency vehicle through traffic such that the emergency vehicle may arrive at a destination more quickly. The system includes a plurality of visual warning devices located along roads and/or at intersections, and a plurality of wireless communications modules. Each wireless communications module is connected to a respective visual warning device, and each wireless communications module has a directivity and a signal threshold defining an activation zone such that when the emergency vehicle enters an activation zone of a respective wireless communications module, the visual warning device connected to said respective wireless communications module displays a first visual warning.
Claims15
An emergency passage system for notification of an approaching emergency vehicle, said emergency passage system comprising:
- a plurality of visual warning devices including a first visual warning device and a second visual warning device for facilitating movement of said emergency vehicle through traffic, said plurality of visual warning devices located along roads and/or at intersections,
- a plurality of wireless communications modules including a first wireless communications module and a second wireless communications module, each wireless communications module comprising:
- a directional antenna adjusted to a predefined direction of travel;
- and
- a processing unit configured to compare a received signal level to a signal threshold and to control a connected visual warning device based on the comparison;
- each wireless communications module being connected to a respective visual warning device,
- each wireless communications module having a directivity and a signal threshold defining an activation zone having a range of angles for transmitting and receiving a wireless signal within said range of angles,
- wherein the visual warning device connected to a respective wireless communications module is activated when the respective wireless communications module receives a transmission signal from the emergency vehicle in response to the wireless signal transmitted by the wireless communications module.
