Map supplier NAVTEQ has made an addition to their mapping material by adding road signs. This new content brings an improved routing and navigation experience to the user by taking into account changing speed limits as well as bends and hills when calculating the route. In addition, twenty-one different road side warning signs such as sharp bend ahead, steep hill, or no overtaking can be used to notify drivers of the fixed road hazards. As well as the new signs, NAVTEQ is also increasing the quantity of data for speed limits.“Our consumer research indicates that speed advisory is a top feature that a driver is looking for when purchasing a navigation system,” said Bruno Bourguet, Vice President and General Manager, Vehicle Applications.

Speed limit alerts can not only inform the driver to this change but also advise when the speed returns to a higher limit. In addition, a driver can be informed about an upcoming hill, curve, or lane merge.These same attributes can aid in route optimization taking into account steep slopes where travel will be slower. “Speed limits and road side warning functionality allows the fleet manager to calculate optimum
