In addition, according to the present invention, the same color as the surrounding blocks (or the average value thereof) is used for blocks that are divided areas (blocks) where there is no congestion data and the surrounding blocks are determined to be congested. By displaying in the color shown or a different color, etc., there is an effect that tooth loss can be prevented.

  Further, according to the present invention, the fill data has different fill modes depending on the traffic congestion level of the traffic jam location. Therefore, in each divided area (block) obtained by finely dividing the map to be displayed, the road network included in the block Depending on the traffic congestion density of the link (for example, the ratio of the traffic congestion link to the traffic information distribution link), the block color, color density, translucency, or fill pattern can be changed and displayed. There is an effect.

  In the above description, the navigation device of the present invention has been described as an example. However, the same effect can be achieved in the terminal device, the navigation system, the navigation server, the navigation method, and the program.

Further, the output data generation unit 402f may further generate output data including guidance data (display guidance data, voice guidance data, etc.) stored in the guidance database 406d. The output data generation unit 402f may further generate output data including text data indicating a scale, a direction, a current time, a radio wave reception level, a menu icon, and / or a place name.

  Then, the output data output unit 402g causes the display unit 414 to display a display screen based on the output data generated by the output data generation unit 402f (step SC-8). Here, the output data output unit 402g includes traffic jam location data including at least map data of a display target map and graphic data representing a traffic jam location included in the output data generated by the output data generation unit 402f. A display screen based on the above may be displayed on the display unit 414.
