Utilize custom-engineered radar detection to keep trains and cars from meeting.CONTACT US
Railroad crossings have been a safety concern for both automobile drivers and railroad operators since the two started crossing paths over 100 years ago. Grade-level crossing islands are designed to allow cars and trains to pass safely at the same location, with safety measures like gates, lights, bells, signs, train horns and vehicle detection in place to keep the crossing island safe for all. Unfortunately, these measures have not always been enough to maintain a safe crossing.
Today, approaches and crossing islands are engineered with enhanced safety measures that are designed to keep cars and trains from meeting. Many of these enhanced measures are popular in newer railroad crossing applications, such as quiet zones and high-speed rail.
One of these enhanced safety measures is the four-quadrant gate crossing, in which four gates prevent access to the crossing from all lanes on both sides of the track. Four-quadrant systems operate dynamically: the entrance gates for both directions of travel descend when activated by an approaching train, preventing any further travel into the crossing island; the exit gates only descend when a vehicle detection system verifies that no vehicles remain in the crossing island, where they could be trapped if all four gates descended simultaneously.
Accurate, reliable vehicle detection is mandatory for a dynamic system like this to be effective. The Island Radar Quad Gate System offers FRA-approved, redundant broad-zone vehicle detection specifically for four-quadrant gate locations. Installed non intrusively in the track wayside, the Island Radar system provides a level of detection that is not feasible with other forms of detection. When configured to operate in dynamic mode with the exit gate management system controllers, the Island Radar system allows for complete safe clearance of the crossing island by placing the exit gates in a safe down position without trapping a vehicle on the island.
The Island radar Quad Gate System also provides:
Island Radar is the detection of choice for Florida’s high-speed rail corridor, and our systems have been installed on numerous crossing safety projects with Class I Railroads. The Island Radar Quad Gate System is proving to be the smarter, safer, more reliable choice for vehicle detection in four-quadrant gate crossings.
Non-intrusive radar sensors allow you to coordinate your traffic systems with railroad systems.
Real-time communication to guide vehicles out of dangerous situations.
Communicate with motorists about blocked crossing soon enough for them to do something about it.
