Instructions: Identify the vulnerable user’s location at the time of the crash. Definition: The location of the vulnerable user with respect to the trafficway at the time of crash. Rationale: By the collecting the location of the vulnerable user at the time of crash, this element is important for developing effective roadway design and operation,…
Instructions: Indicate the actions made by the vulnerable user just prior to the crash based on verbal or physical evidence, but not on speculation alone. Definition: The action of the vulnerable user immediately prior to the crash and an indication of whether the vulnerable user was walking/cycling to/from school. Rationale: By collecting the actions and…
Instructions: Select the road conditions that potentially contributed to the crash. Definition: Apparent environmental or roadway conditions which may have contributed to the crash. Rationale: This element is important for identifying the existence of unusual conditions that can be useful for determining the need for additional traffic control devices or geometric improvements. It is also…
Instructions: Select the characteristic that best describes the event that caused the first harm to the vehicle/occupants. Definition: The first injury or damage-producing event that characterizes the crash type. Rationale: This element is needed for uniformity in reported motor vehicle crash statistics, understanding crash causation, and identifying possible crash avoidance countermeasures. For analytic purposes it…
Instructions: Select the appropriate characteristic that best describes the location of the first harmful event. Definition: The location of the first harmful event as it relates to its position within or outside the trafficway. Rationale: This element is important for identifying highway geometric deficiencies. Code Attribute Definition Example 1 Roadway The part of a trafficway…
Instructions: Enter the Manner of Collision code for the vehicles involved in the initial or first collision. Definition: The identification of the manner in which two motor vehicles in transport initially came together without regard to the direction of force. This data element refers only to crashes where the first harmful event involves a collision…
Instructions: Select ‘yes’ or ‘no’ to indicate whether this crash occurred in a work zone. Definition: Indicating a crash that occurs in or related to a construction, maintenance, or utility work zone, identified by warning signs/signals/indicators, including those on transport devices (e.g. signs, flashing lights, channelizing devices, barriers, pavement markings, flagmen, warning signs and arrow…

The school bus, with or without a passenger on board, must be either directly involved as a contact motor vehicle or…
Instructions: Select the characteristic that best describes the design of the road on which this vehicle was traveling. Definition: Indicates whether the trafficway for this vehicle is divided and whether it serves one-way or two-way traffic. A divided trafficway is one in which roadways for travel in opposite directions are physically separated by a median.…
Instructions: Select the characteristic that best describes the location of the crash. Definition: An intersection consists of two or more roadways that intersect at the same level. Rationale: This is important for site-specific safety studies to identify actual or potential safety problem locations. Code Attribute Definition Example 1 Not At Intersection This attribute identifies that…
