Traffic Crashes - People

This data contains information about people involved in a crash and if any injuries were sustained. This dataset should be used in combination with the traffic Crash and Vehicle dataset. Each record corresponds to an occupant in a vehicle listed in the Crash dataset. Some people involved in a crash may not have been an occupant in a motor vehicle, but may have been a pedestrian, bicyclist, or using another non-motor vehicle mode of transportation. Injuries reported are reported by the responding police officer. Fatalities that occur after the initial reports are typically updated in these records up to 30 days after the date of the crash. Person data can be linked with the Crash and Vehicle dataset using the “CRASH_RECORD_ID” field. A vehicle can have multiple occupants and hence have a one to many relationship between Vehicle and Person dataset. However, a pedestrian is a “unit” by itself and have a one to one relationship between the Vehicle and Person table.

本数据集包含了事故中涉及人员的详细信息以及是否遭受了伤害。该数据集应与交通事故及车辆数据集结合使用。每条记录对应于事故数据集中列出的车辆乘客。部分参与事故的人员可能并非机动车乘客，而是行人、自行车骑行者或使用其他非机动车交通方式。报告的伤害由响应的警察官员提供。事故发生后发生的死亡情况通常在事故日期后的30天内更新这些记录。个人信息可通过“CRASH_RECORD_ID”字段与交通事故及车辆数据集相连接。一辆车可能有多名乘客，因此车辆与人员数据集之间存在一对多关系。然而，行人作为一个“单元”本身，与车辆与人员表之间存在一对一的关系。
