Roadkill Prevention System

To maximize roadkill prevention effectiveness, this device both warns drivers when animals approach the road and deters animals from entering the roadway

​​How to prevent Roadkill

Motion /Thermal Imaging Sensor: Detects wildlife within a 20-meter radius. 

1.  Animal Deterrence Funtions

 

1) LED Flasher: Automatically blinks upon detection by the sensor. 

2) Speaker: Emits multiple frequency bands simultaneously to deter animals. 

These functions remain active for approximately one minute after activation. 

2. Driver Warning Functions

1) LED Warning Light: Flashes to alert drivers and prompt them to slow down.

Real-World Application

Mounted on the front upper section of trains, the system allows operators to activate high-frequency sound bursts when approaching wildlife. This proactive measure minimizes train stoppage time and enhances safety in areas prone to animal crossings.

Optimized for Large Mammals

The speaker is particularly effective against large mammals, making it ideal for use in regions with frequent wildlife encounters. Its robust design and high output make it suitable for integration into special-purpose vehicles operating in remote or high-risk zones.
