The traverse distance of a speed bump is typically less than or near to 0.3 m (1 ft); contrasting with the wider speed humps, which typically have a traverse distance of 3.0 to 4.3 m (10 to 14 ft). [ 5 ] [ 6 ]
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 ...

The report also noted that the problem was most severe in developing ...

[7] [41] As a speed reduction measure, TRS have been marginally successful. A 2003 Texas study concluded: "However, the actual reductions in speeds have been in the range of 2 to 8 mph (3 to 13 km/h), which may be barely perceptible to the traveling public. There have been no studies that evaluate the reduction of excessive speeds." [7]
