1. A warning system, the warning system comprising:
- a first sensor station, wherein the first sensor station comprises;
a sensor mount configured to mount the sensor station to a portable traffic object,wherein the portable traffic object is configured to visually warn others of a work area;
a motion sensor for detecting a vehicle approaching the work area; and
a wireless transmitter configured to transmit a signal in response to detection of the vehicle; and
a safety vest, wherein the safety vest comprises;
a transceiver configured to receive a warning signal from the first sensor station; and
a first light source and second light source configured to transmit light in response to receiving the warning signal, wherein the first light source is located on the front of the safety vest and the second light source is located on the back of the safety vest;
a second and third sensor station, wherein the second and third sensor stations are identical to the first sensor station, andwherein the first, second, and third sensor stations are configured to communicate with each other using a wireless communication protocol,wherein the second sensor station is configured to transmit a second signal in response to detection of the vehicle;
wherein the third sensor station is configured to transmit a third signal in response to detection of the vehicle;
wherein the first, second, and third sensor stations are configured to verify that the vehicle is approaching the safety vest based on the first, second, or third signal and communicating using the wireless communication protocol between the sensor stations; and
wherein the first, second, and third sensor stations are configured to reduce false alarms related to the vehicle approaching the work area based on communications between the sensor stations or based on wireless communication with a centralized traffic system.

Abstract
The disclosed technology comprises a system to provide warning of a rail or vehicle approaching a work area for a transit worker or group of transit workers. In some implementations, the disclosed technology includes a sensor station that detects rail or vehicles approaching the work area, which transmits a warning signal to a safety vest worn by workers. In some implementations, the safety vest has a transceiver to receive the warning signal and activates an alarm mounted to the vest. The alarm may be a flashing light or a vibration that can be felt by the vest wearer.

12. A method to provide a warning to a transit worker, the method comprising:
-
detecting, at a first sensor station, a first signal that indicates a vehicle is approaching a transit worker area, wherein the sensor station is configured to mount to a portable traffic object, wherein the portable traffic object is configured to visually warn others of the transit work area; verifying, at a second or third sensor station, that the vehicle is approaching a transit worker wearing a transit safety vest based on detecting a second signal that also indicates the vehicle is approaching the transmit worker area and communicating using a wireless communication protocol between the sensor stations; transmitting, by the first, second, or third sensor station, a warning signal to the transit safety vest worn by the transit worker; and activating lights on the transit safety vest in a pattern to make the vest visible to the approaching vehicle, wherein the lights are located on the front and back of the transit safety vest. - View Dependent Claims (13, 14, 15)

16. A non-transitory computer-readable medium storing instructions that when executed by a processor cause a device to perform operations to warn a transit worker, the operations comprising:
-
detecting, at a first sensor station, a vehicle is approaching a transit worker area, wherein the sensor station is configured to mount to a portable traffic object, wherein the portable traffic object is configured to visually warn others of the transit work area; verifying, at a second or third sensor station, that the vehicle is approaching a transit worker wearing a transit safety vest based on detecting a second signal that also indicates the vehicle is approaching the transmit worker area and communicating using a wireless communication protocol between the sensor stations; transmitting, by the first, second, or third sensor station, a warning signal to the transit safety vest worn by the transit worker; and activating lights on the transit safety vest in a pattern to make the vest visible to the approaching vehicle, wherein the lights are located on the front and back of the transit safety vest. - View Dependent Claims (17, 18, 19)
