The advent of Automatic Vehicle Location (AVL) technology on snowplows has opened up a world of possibilities for using data to improve winter operations. By using GPS technology to track plows’ progress along their routes, AVL provides a data set that can help agencies optimize route efficiency. Knowing a plow’s location also lets supervisors evaluate plow sensor data and adjust to changing conditions in real time. Many agencies allow the public to track plow locations online, and some go a step further, with camera feeds providing an operator’s-eye view of the road.
