A sign cover includes a first portion fixed at a top side thereof with a top side of a second portion. Peripheral edges of the portions extend past a peripheral edge of a sign by a margin area when the portions are positioned over a front side and a rear side of the sign in a deployed configuration. The margin area of the portions each include a plurality of two-part mechanical fasteners. As such, in use, with the first portion and the second portion draped over the sign, the two-part mechanical fasteners hold the cover onto the sign. The first portion may include one or more transparent pockets for displaying one of several alternate signs.

A plowtector system for extending a snow marker pole over a residential curb. The plowtector system reduces the chance of damage to a curb and/or snow plow when plowing is necessary. A snow marker pole placed within the plowtector system reaches over where the curb starts so that the snow plow operator has a clearer indication of how far to the side they can travel. Should the plowtector system be struck by a snow plow, the system can twist from side to side, reducing the amount of damage that may be caused by such action. The integral components of the plowtector system keep the snow marker in a level position, and bypass the possibility of the snow marker becoming lodged in snow or ice.

The present disclosure provides a method and a device for acquiring dynamic map data, and a storage medium. The method includes: acquiring, by a road operation device having a network access capacity, dynamic map data of a road work site where the road operation device is located; and providing, by the road operation device having the network access capacity, the dynamic map data to a map service system through a dynamic map data acquisition system, such that the map service system reflects content of the dynamic map data in a predetermined product form.

The device with electrical or pneumatic actuation of a folding mechanism for encouragement of reduction of vehicle speed consists of bars with accelerometers that function as step-on sensors, which transmit information to a controller that immediately determines the speed of the movement of a vehicle, after which it sends an order to an actuator with electric motor or a pneumatic actuator with an aim of raising the folding speed reduction mechanism in the case when the vehicle moves at a speed that is higher than the one programmed into the controller and after a certain period of time to return the device to its standby position, or to leave it in the standby position, i.e. not to raise the folding speed reduction mechanism. if the vehicle is moving at a speed that is lower than the one programmed in the controller.
