METHOD OF SAFE TRAFFIC AND MACHINE TO THIS END Russian patent published in 2013 - IPC E01H5/00 

FIELD: machine building.

SUBSTANCE: roads are constructed and cleaned of snow and landslides by two go-ahead transverse walking blades to make two roadways and three protection windrows: at road axis and two roadsides. For multi-lane traffic, roadway is expanded by go-ahead transfer of snow and other material by working tools of walking gear along and across the road. Snow windrows make a base line to form motion path. Note here that solid line is composed of snow windrow. Proposed machine comprises walking blades-hands and/or go-ahead tools for displacement of snow and other materials to create windrow at roadsides and road axis. The blade is connected with guide wheel and incorporates the windrow dubbing function. Said blades-hands are furnished with turn limiters and walking and material displacement settings. Snow windrows at road axis and sides prevent collision of vehicles.

EFFECT: higher traffic safety, efficient production and application of machinery.
