Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. [1] [2] [3]
1968 Plymouth Road Runner. So popular was the image of road-burning speed inspired by the Road Runner, that Plymouth (a division of Chrysler) named one of their V8-powered "muscle car" models after the cartoon bird. The car was fitted with Road Runner decals and a horn that made the well-known "beep, beep" sound when activated.
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
Traffic engineers refer to three "E's" when discussing traffic calming: engineering, (community) education, and (police) enforcement.Because neighborhood traffic management studies have shown that residents often contribute to the perceived speeding problem within their neighborhoods, instructions on traffic calming (for example in Hass-Klau et al., 1992 [4]) stress that the most effective ...
Within 15–50 m from the roadside, air pollution concentration levels at the lee side of the noise barriers may be reduced by up to 50% compared to open road values. [13] Noise barriers force the pollution plumes coming from the road to move up and over the barrier creating the effect of an elevated source and enhancing vertical dispersion of ...

In some shorts, the Road Runner makes a noise while sticking his tongue out at Wile E. Coyote, which resembles its actual call. The cartoons rely on a misconception that a roadrunner is much faster than a coyote. In fact, a coyote's fastest sprinting speed is 64 km/h (40 mph), [26] which is twice that of a roadrunner's at 32 km/h (20 mph). [10]
