Server device, congestion prediction information display system, congestion prediction information distribution method, congestion prediction information display method, and program

Abstract

According to the present invention, an information terminal (2) transmits information representing the current location and the acceleration to a server device (3). The server device (3) receives the information representing the current position and the acceleration from the information terminal (2), generates a congestion prediction degree using the information representing the acceleration, associates the congestion prediction degree and map data so that the congestion prediction degree can be displayed on a road map, and transmits association information representing the association. The information terminal (2) uses the association information transmitted from the server device (3) to display the congestion prediction degree on a road map on a display device (16).

Description

technical field [0001] The present invention relates to a server device, a traffic jam sign information display system, a traffic jam sign information release method, a traffic jam sign information display method and a program. [0002] This application claims the priority of Japanese Patent Application No. 2013-048176 filed on March 11, 2013, and uses the content of the application here. Background technique [0003] In the prior art, a system is known (for example, refer to Patent Document 1): the system has a server device and a plurality of information terminal devices capable of communicating with each other through a wireless communication network, and the server device is based on information carried by occupants of the vehicle. The location information of the terminal device detects whether there is a traffic jam, associates (associates) the detection result with the map information, and sends the detection result to the information terminal device, and the informati...
