Traffic Sign Type

Traffic Sign Type identifies the type of warning sign.

Traffic Sign Type can be used to give specific driver alert messaging using the sign type. Traffic Sign Type can also be used to display the traffic sign.

The Stop Sign attribute is used for map display and to improve travel time guidance.

• The appearance of the signs listed above can vary depending on the situation in reality. There are also differences in the appearance of signs between countries.
• Generally, the corresponding Traffic Sign Type is applied based on what is posted. See the following table for examples:

• Unprotected railway crossings can just have a St. Andrew’s Cross (see the following image) or other type of indication (country specific) at the actual railway crossing and no sign indicating a railway crossing prior to the crossing. The signs at the actual railway crossing are not considered for Traffic Sign implementation. However, all railway crossings with and without a Railway Crossing sign prior to the crossing are applied with a Railway Crossing condition.
