Abstract
A driver safety system includes traffic signals communicating with a municipal controller via a first network and user devices communicating with a third party controller via a second network. Communications from the first network are provided to the second network via a repeater server providing one-way communications to avoid the possibility of hacking devices on the first network.
Claims13
A vehicular traffic system, comprising:
- a municipal controller operatively connected with a plurality of traffic signals via a first communications network;
- a third party controller operatively connected with a plurality of user devices via a second communications network;
- and a repeater server configured to provide communications from the first communications network to the second communications network via a unidirectional communications channel;
- wherein the unidirectional communications channel comprises a dedicated output port of a switch connecting the municipal controller with the repeater server;
- and wherein further the unidirectional communications channel comprises a dedicated input port of the repeater server.
2 more elements
A method of sharing traffic signal state information on a private computer network to a device on a public computer network, the method comprising:
- passing the traffic signal state information as a data signal through a network switch device;
- outputting the traffic signal state information on a one-way communications channel from the network switch device to a repeater server;
- processing the traffic signal state information into output data at the repeater server;
- and passing the output data from the repeater server to the public computer network;
- wherein the one-way communications channel comprises a dedicated output port of the network switch device connecting the private computer network with the repeater server;
- and wherein further the one-way communications channel comprises a dedicated input port of the repeater server.
