Traffic Crashes - Vision Zero Chicago Traffic Fatalities

Traffic fatalities within the City of Chicago that are included in Vision Zero Chicago (VZC) statistics. Vision Zero is Chicago’s commitment to eliminating fatalities and serious injuries from traffic crashes. The VZC Traffic Fatality List is compiled by the Chicago Department of Transportation (CDOT) after monthly reviews of fatal traffic crash information provided by Chicago Police Department’s Major Accident Investigation Unit (MAIU).

CDOT uses a standardized process – sometimes differing from other sources and everyday use of the term -- to determine whether a death is a “traffic fatality.” Therefore, the traffic fatalities included in this list may differ from the fatal crashes reported in the full Traffic Crashes dataset (https://data.cityofchicago.org/d/85ca-t3if).

Official traffic crash data are published by the Illinois Department of Transportation (IDOT) on an annual basis. This VZC Traffic Fatality List is updated monthly. Once IDOT publishes its crash data for a year, this dataset is edited to reflect IDOT’s findings.

VZC Traffic Fatalities can be linked with other traffic crash datasets using the “Person_ID” field.

State of Illinois considers a “traffic fatality” as any death caused by a traffic crash involving a motor vehicle, within 30 days of the crash. Fatalities that meet this definition are included in this VZC Traffic Fatality List unless excluded by any criteria below. There may be records in this dataset that do not appear as fatalities in the other datasets.

The following criteria exclude a death from being considered a "traffic fatality," and are derived from Federal and State reporting standards.

1. The Medical Examiner determined that the primary cause of the fatality was not the traffic crash, including:

a. The fatality was reported as a suicide based on a police investigation.

b. The fatality was reported as a homicide in which the "party at fault" intentionally inflicted serious bodily harm that caused the victim's death.

c. The fatality was caused directly and exclusively by a medical condition or the fatality was not attributable to road user movement on a public roadway. (Note: If a person driving suffers a medical emergency and consequently hits and kills another road user, the other road user is included, although the driver suffering a medical emergency is excluded.)

2. The crash did not occur within a trafficway.

3. The crash involved a train or other such mode of transport within the rail dedicated right-of-way.

4. The fatality was on a roadway not under Chicago Police Department jurisdiction, including:

a. The fatality was occurred on an expressway. The City of Chicago does not have oversight on the expressway system. However, a fatality on expressway ramps occurring within the City jurisdiction will be counted in VZC Traffic Fatality List.

b. The fatality occurred outside City limits. Crashes on streets along the City boundary may be assigned to another jurisdiction after the investigation if it is determined that the crash started or substantially occurred on the side of the street that is outside the City limits. Jurisdiction of streets along the City boundary are split between City and neighboring jurisdictions along the street centerline.

5. The fatality is not a person (e.g., an animal).

本数据集收录了芝加哥市内纳入‘零愿景芝加哥’（Vision Zero Chicago，VZC）统计的交通事故死亡案例。‘零愿景’是芝加哥市致力于消除交通事故中死亡和严重伤害的承诺。VZC交通事故死亡名单由芝加哥交通部（Chicago Department of Transportation，CDOT）编制，该名单是在对芝加哥警察局重大事故调查组（Major Accident Investigation Unit，MAIU）提供的每月死亡交通事故信息进行月度审查后形成的。CDOT采用一套标准化流程（有时与其他来源和日常用语的使用存在差异）来确定死亡是否属于‘交通事故死亡’。因此，本名单中的交通事故死亡案例可能与完整交通事故数据集中的死亡事故报告存在差异（https://data.cityofchicago.org/d/85ca-t3if）。伊利诺伊州交通部（Illinois Department of Transportation，IDOT）每年发布官方交通事故数据。VZC交通事故死亡名单每月更新。一旦IDOT发布年度事故数据，本数据集将据此进行编辑以反映IDOT的调查结果。VZC交通事故死亡案例可以通过“Person_ID”字段与其他交通事故数据集进行关联。伊利诺伊州将任何由机动车辆引起的交通事故造成的死亡视为‘交通事故死亡’，并在30天内发生的此类死亡案例中纳入本VZC交通事故死亡名单，除非符合以下任何一项排除标准。本数据集中可能存在不作为其他数据集死亡案例记录的记录。以下标准排除死亡案例被认定为‘交通事故死亡’，并源自联邦和州报告标准。

1. 法医鉴定认为死亡的主要原因并非交通事故，包括：

a. 根据警方调查，死亡案例被报告为自杀。

b. 死亡案例被报告为他杀，其中‘责任方’故意造成严重身体伤害导致受害者死亡。

c. 死亡直接且唯一由医疗状况引起，或死亡与公共道路上的道路使用者移动无关。（注：如果驾驶员在驾驶过程中突发医疗紧急情况并因此撞击并杀死其他道路使用者，则其他道路使用者将被纳入，尽管突发医疗紧急情况的驾驶员将被排除。）

2. 事故未发生在交通道路上。

3. 事故涉及火车或其他在铁路专用车道内运输的方式。

4. 死亡发生在不受芝加哥警察局管辖的道路上，包括：

a. 死亡发生在高速公路上。芝加哥市不对高速公路系统进行监管。然而，如果高速公路匝道上的死亡发生在市管辖范围内，将被计入VZC交通事故死亡名单。

b. 死亡发生在城市界限之外。如果经调查确定事故始于或主要发生在城市界限之外的一侧，街道上的交通事故可能被分配给其他管辖区域。城市边界街道的管辖权在城市和相邻街道中心线附近的邻近管辖区域之间分割。

5. 死亡者并非人（例如，动物）。
