Description

As the position specifying function of the mobile terminal, a GPS receiver having a position specifying function with high accuracy ( position specifying error: several tens of centimeters or less) is assumed. With this GPS receiver, not only the position of the moving body but also the moving speed of the moving body can be specified, or the position specifying timing between the moving bodies can be synchronized using highly accurate time information.

The traffic safety support system configured as described above, the movable body side is excessive over - a sensor function, without the need for equipment of the signal processing functions, i.e., approaching the other mobile body including the movement prediction of the own mobile body -Predicting the danger of moving the moving body in advance, easily and accurately by making the center device bear all the collision risk judgments and detection of abnormalities in the state of movement on the road. Therefore, the spread of the system and the resulting great traffic safety effect can be expected.

Claims (4)

Mobile terminal group having position specifying function, voice / display output function, communication function with center device, map database including detailed road / building shape information, communication function with mobile terminal, storage function, calculation A center device having a processing function,
Each mobile terminal periodically specifies the position of the mobile body and transmits the specified result to the center device.
In the center device, from the history of moving body specific position information periodically sent from each mobile terminal, the movement, movement, direction, speed, etc. of the moving body within a certain time after the present time for each moving body While performing state prediction, it mutually compares with the movement state prediction result of the surrounding other moving body corresponding to the movement prediction result of each moving body, or the surrounding road / building shape / size corresponding to the movement prediction result of each moving body Comparing the relative relationship with the data for each mobile object, and providing the mobile object with safe movement support by transmitting the fact to the mobile object regarding the mobile object having a traffic safety problem. Traffic safety support system. The traffic safety support system according to claim 1 , wherein the position specifying cycle in the moving body is a cycle corresponding to the moving speed of the moving body. In the transmission information from the mobile body to the center device, the mobile body type, the mobile body shape, the position specifying function installation location in the mobile body, etc. can be specified as a two-dimensional plane or a three-dimensional solid. The center device, including information, uses the two-dimensional or three-dimensional shape information of the moving object to detect a two-dimensional or three-dimensional danger between the moving objects or between the moving object and the mutual position of the road / building. The traffic safety support system according to claim 1 , wherein an abnormality is detected. The moving state of each moving object is predicted as a two-dimensional or three-dimensional trajectory corresponding to the two-dimensional or three-dimensional shape size of the moving object, and the risk determination of abnormal approach / collision between moving objects is supported. 4. The traffic safety support system according to claim 3 , wherein the determination is made based on a positional / temporal intersection amount of a two-dimensional or three-dimensional movement state prediction trajectory between moving bodies.
