| 摘要 |
The present invention relates to a speed management system adapted and intended to be positioned in a road section, intended for the advancement of a vehicle, with the intention of causing a vehicle driver to reduce the speed of the vehicle along a road length, that said speed management system comprises a speed obstacle (4), comprising two sections structured as a mat and stacked on top each other, said sections forming a lower surface portion (41) and an upper surface portion (42), respectively, wherein the speed obstacle is adapted to be capable of assuming a first inactive position (Ll) and a second active position (L2), that an upper surface section of the speed obstacle is adapted to assume a position planar or substantially planar with the upper surface of the road section in said first inactive position (L2), and that the upper surface section of the speed obstacle is adapted to assume a raised position in relation to the upper surface of the road section in said second active position (L2), that said speed obstacle also contains an internal space which is completely or partially fillable with a non- compressible fluid (36), that said speed management system comprises a pressure generating means (30) for filling said internal space with the non-compressible fluid, wherein there is a first connection (7, 9), from a reservoir (35) for the non-compressible fluid (36) via said pressure generating means (30), to said internal space. |
