  "textContent": "Traffic information by a deformed map is efficiently produced from traffic information made of \"road geometry data\" and \"event location data.\" The association between each link on a digital map and a rectangle forming an event presenting unit on the deformed map is set in advance and held by a deformed map data portion 25. Map matching between received road geometry data and digital map data is carried out by a map matching portion 22, a road section on the digital map is specified, a link on the digital map corresponding to the location of an event is specified based on received event information data and the digital map data 23 for said road section, and a rectangle to represent event information based on the event information data on the deformed map is determined based on the previously set association for the link. In this way, level 2 traffic information can efficiently be produced based on the \"road geometry data\" and \"event location data.\"",
