    摘要: A system and method are disclosed that provide traffic information to end users. The traffic information is contained in traffic data messages that use location reference codes to identify locations along roads. A data structure is formed that relates a set of location reference codes assigned to locations along roads by a first data supplier to another set of location reference codes assigned locations along roads by a second data supplier. The data structure is used to form traffic data messages containing location reference codes assigned by the first data supplier based on traffic data messages containing location reference codes assigned by the second data supplier.
