Provided is a traffic safety assistance system capable of quickly performing risk notification to a traffic participant when the behavior of the traffic participant suddenly changes. A traffic safety assistance system is provided with: a server device that predicts future behaviors of a plurality of traffic participants; and a notification device for notifying the plurality of traffic participants on the basis of the prediction result of the server device. The notification device includes a portable terminal (14) that moves together with a second traffic participant (72). The portable terminal (14) receives the future trajectory of the first traffic participant (71) from the server device, calculates the velocity vector of the second traffic participant (72), determines whether or not there is a risk between the first traffic participant (71) and the second traffic participant (72) on the basis of the future trajectory of the first traffic participant (71) and the velocity vector of the second traffic participant (72), and transmits the risk to the server device. If it is determined that the risk has occurred, a risk notification, which is a risk-related notification, is made to the second traffic participant (72).
提供交通安全辅助系统,在交通参与者的行为突然变化的情况下能够迅速地进行对交通参与者的风险通知。交通安全辅助系统具备:服务器装置,预测多个交通参加者的将来的行为;通知装置,基于服务器装置的预测结果,进行对多个交通参加者的通知。通知装置包括与第二交通参与者(72)一起移动的便携终端(14)。便携终端(14)从服务器装置接收第一交通参与者(71)的将来轨道,计算第二交通参与者(72)的速度矢量,根据第一交通参与者(71)的将来轨道和第二交通参与者(72)的速度矢量,判定在第一交通参与者(71)与第二交通参与者(72)之间是否产生风险,在判定为产生风险的情况下对第二交通参与者(72)进行与风险有关的通知即风险通知。
