ROADSIDE MAINTENANCE ENHANCES HIGHWAY'S FUNCTION

The clear zone, or area between the highway shoulder and the controlled woodland fringe, performs a number of safety functions. Where the right-of-way is wide enough and has suitable terrain, the clear zone can assist driver who loses control of a vehicle to recover control and, hopefully, avoid hitting a deadly fixed object like a tree or ledge. Good clear zone management around curves, at intersections, and on hills enables the driver to see pedestrians, cyclists, approaching vehicles, and stopped school buses and rural mail carriers. Mowing is essential to maintenance of thick grass, which is resistant to damage by storm runoff from the pavement. And, where terrain and soil drainage permit, mowing costs are comparable with those of chemical brush control. The esthetics are a by-product of those two functions. Controlled secondary plants used to suppress unwanted brush has an application at specific roadside locations. And there is a variety of brush-cutting machinery in the marketplace that warrants some time-study work on highways.
