Ehdotuksen soveltamisala:Speed limits are usually indicated to the driver through roadside signs. Drivers who are aware of the speed limit at all times are more likely to drive safely, which improves road safety. Most speed limit signs are static and remain for years and are thus available through navigation system map databases. However, there is an increasing number of variable message signs, temporary signing (e.g. for road works) and also changed speed limits which are not reflected in the map databases yet. Speed limit information is offered in an accurate way so that different lanes and different vehicle types can be differentiated. TPEG Speed Information allows the drivers to be aware of the current allowed (maximum) speed, by delivering timely information about the current position and values of speed limits to the navigation or driver assistance systems. The data is seen as informational and will be encoded in a compact way to minimize bandwidth consumption. TPEG2-SPI supports direct and indirect speed limits. Direct speed limits are used for signs showing a maximum speed a vehicle is allowed to travel. Such speed limit signs can be static or dynamic. Indirect speed limits are referring to the speed of other road users. Mostly the vehicle in front of the own vehicle is used as a reference.
