VISION ZERO A strategy aimed at eliminating all traffic fatalities and severe injuries while increasing safe, healthy, and fair access to mobility for al l. SAFE SYSTEM APPROACH A holistic framework that acknowledges human error and vulnerability in crashes, emphasizing redundancy in roadway design, vehicle safety, and policies to prevent severe injuries and deaths . TRAFFIC CRASH [NOT ACCIDENT!] The word “accident” implies that these harmful and life-changing events are not preventable or avoidable. Traffic-related severe injuries and deaths are often preventable events for which there are proven solutions. As such, the Safety Action Plan refers to them as “crashes,” not “accidents.” KILLED AND SEVERELY INJURED (KSI) Killed and Severely Injured (KSI) stands for the highest level of severity resulting from a traffic crash with at least one person involved in the crash either dead or suffering incapacitating injury .
VULNERABLE ROAD USERS (VRU) Vulnerable Road Users (VRUs) are those at most risk in a traffic crash by not being inside an enclosed vehicle. When they are involved in crashes, VRUs are more likely to be severely injured or killed. HIGH INJURY NETWORK (HIN) A data-driven map identifying streets and intersections with the highest concentration of fatal and severe crashes used to identify priority safety improvements . SOCIAL VULNERABILITY Social vulnerability refers to the potentially negative effects that external stressors have on communities. The Centers for Disease Control and Prevention (CDC) has developed a tool to help identify and map communities that are most likely to need support before, during, and after hazardous events. It measures the relative vulnerability of each U.S. census tract by ranking them on 16 social factors, including unemployment, racial and ethnic minority status, and disability status. These factors are grouped into four related themes, providing each census tract with a ranking for the individual variables, the four themes, and an overall ranking. This tool was used to identify the most socially vulnerable communities in Fort Worth.
