The LinqThingz IoT company invented TrainLinq, a predictive mobility solution that provides warnings of blocked intersections before train arrival. TrainLinq allows road traffic to be rerouted in advance of crossing blockage to eliminate the wait time for emergency, delivery, and passenger vehicles. TrainLinq systems have been successfully deployed in two cities for over two years.Designed all hardware and firmware for pole-mounted equipment while Kurt Brandt developed the custom cloud solution..https://linqthingz.com/
