This just looks like a solution for a problem that does not exist. Speed bump geometry can satisfy the need for a smooth ride at slow speeds. There are three general types of traffic calming devices that would get slotted into the "speed bump" category: 1) traditional speed bumps, 2) speed humps, and 3) speed tables. I won't bother explaining a traditional speed bump as many of us are already familiar with them. A speed hump is generally longer, in the direction of travel, than a speed bump but not so long that a normal passenger vehicle will have both axles on the hump at the same time. A speed table is long enough, again in the direction of travel, that both axles of a passenger vehicle will be on top of the table. With both humps and tables the transition can be designed for a given effect. A sudden transition will be more severe to motorists, while a long, gradual transition can make the hump or table comfortable for the motorist. With all of these traffic calming options emergency vehicles are a concern. However, traffic calming measures like these should not be placed on roadways that will be frequently traveled by emergency vehicles. These traffic calming measures should be placed on low-volume, low-speed local roads.
