A multi-sided wheel to replace one of the wheels of an existing cold milling machine. The wheel has a series of flat surfaces in spaced relationship. The flat surfaces allow the machine to drop its cutting drum relative to the surface over which the machine is traveling to cut a rumble strip. As the wheel rotates, it will support the machine on one of the points formed by the confluence of two adjacent flat surfaces, thereby raising the machine and causing it to raise its cutting drum out of the rumble strip that it has just cut. Because the flat surfaces are spaced apart, the cutting drum will be moved forward in a looping fashion as the wheel rotates before the wheel drops onto the next flat surface to lower the cutting drum for cutting the next, spaced rumble strip. Thus, the multi-sided wheel causes the machine to move up and down as it propels along its path of travel. A pentagonal wheel is the optimal design for use in conjunction with a Wirtgen.RTM. W500.TM. cold milling machine in order to cut rumble strips meeting the specifications of the New York Thruway Authority. |

DETAILED DESCRIPTION Since the completion of interstate highway system in this Country, experts have come to realize that the uniformity of the interstate highway system can be almost hypnotic, causing the driver of an automobile to become less attentive to his driving.
Further, people tend to drive for longer periods of time and late at night causing drowsiness and the tendency to dose off at the wheel.
If the driver is not alert, either because he is in trance by the monotony of the interstate highway or is travelling late at night and gets sleepy, a very dangerous situation exists.
Since the automobile is usually travelling at a high rate of speed, if the driver is sleepy and doses at the wheel, the automobile could easily run off of the road, crash and cause serious injury to the driver, other drivers in the area, and the destruction of their automobiles and other property.
If a driver begins to run off of the road because he has dosed or fallen asleep, it has been learned that he can be awakened, alerted or otherwise startled in sufficient time generally to recover and bring his vehicle back into the proper travel lane if a series of ruts are formed in the shoulder of the highway immediately adjacent the travel lane.
Ruts are preferable to ridges because they do not wear down with time, they do not require extra material, and they do not interfere with snow plow operations and the like.
When constructing new highways, the ruts, generally known as rumble strips, can be formed in the shoulders of the highway and provide this safety feature as a part of the new construction.
Unfortunately, most of the interstate highway system was developed prior to the discovery of the benefits of rumble strips in the shoulders of highways and the tremendous savings, measured in terms of lives saved and property damage avoided, that could be achieved by the provision of such a feature as an adjunct to highway design.
Thus, it has become necessary, in order to provide rumble strips adjacent preexisting highways, to cut rumble strips into existing road shoulders
