Deer can be a dangerous hazard on the road, here’s the tech that’s helping prevent collisions

With the rising population of deer in our region, there is an increased risk for related vehicle collisions. These can be incredibly dangerous, not just for the deer, but for you and other drivers.

Luckily, there’s plenty of cutting-edge technology (and relatively simple tech, too) that can make the roads safer, as outlined by the Wildlife Collision Prevention Program.

  • Fencing - Something as simple as fencing along the roads has been found to be the most effective method in preventing deer-vehicle collisions.
  • Animal detection infrastructure - A relatively new method that’s being tested, the system could detect when an animal is in the area, and flash a notification on a sign for the driver to see. These could be most effective on roadways that are known for frequent crashes involving animals.
  • Highway lighting - Another simple method that has been proven to make roads safer, sufficient lighting on roadways can ensure a driver can see deer coming from further away, whereas a driver may only notice a deer on a dark road when it’s too late.
  • Infrared sensors - Detection of animals via infrared sensors is becoming a more accessible method for preventing collisions, with many available products for you to add to your car. This technology could make the roads safer by it’s early detection of animals, resulting in the avoidance of a collision.
  • Collision warning systems - Something that is now being implemented into many newer cars, sensors in your car can help alert you, or even automatically apply the brakes when there is an obstacle/animal in the road. Since many new cars use this technology, it should become more accessible and common as time moves on.

Common methods, such as attaching whistles to your vehicle or scent-based repellents have been found to be less effective than many think, according to the Wildlife Collision Prevention Program’s study.
