Method for emergency vehicle traffic control using Bluetooth wireless technology

Disclosed is a method for emergency vehicle traffic control using Bluetooth (BT) wireless technology. Benefits include improved performance, reliability, and function.

General description

              An emergency vehicle approaches a traffic light during a critical situation (see Figure 1). To preserve orderly traffic flow, the light is required to change to green (Go). The conventional solution is that the emergency vehicle has a strobe light that activates a signal change when it is detected by a photoreceiver in the traffic light. In the event that the light from the strobe light on the emergency vehicle is lost or blocked or the photoreceiver on the street light malfunctions or is blocked by a large vehicle, the street light may not change quickly enough or at all.

              By putting a BT transceiver into both the emergency vehicle and the traffic light control system, the traffic light can recognize the authorized Bluetooth transmission and change the traffic control more reliably and much quicker than with conventional strobe light technology.

Detailed description

              The BT transceiver in the emergency vehicle would be tied to the siren/lights.

Its broadcast power would be boosted to the maximum BT limit of 100 meters. The low-cost receiver in the streetlight (or streetlight control system) can quickly recognize the trusted Bluetooth transmitter not only through its Bluetooth ID but also through the successful r...
