Abstract

The fact that Texas had the worst record of fatal crashes in the United States and one of the fastest growing rates in population for the last decades, accident prevention is an important topic for the public health and a safer environment of our future society.

Variable risk analysis was performed for all occupants in passenger vehicles in Texas during the study period of 2012 to 2016. The study focused on model years from 2003 and beyond due to the new safety standard in regard to the child safety seat requirements in the rear position. Risk assessment was performed to compare MSA (Metropolitan statistical areas) counties and non-MSA counties. Risk assessment include comparison between daytime and nighttime as well as injury severity. Relative risk was compared between the front and rear passengers for restrained passengers. Different age groups, gender, model year, vehicle types, manner of collision, and airbag deployments were selected for the attributes of each relative analysis.

To understand further the relationship between child fatalities and restraint usage were evaluated for Texas Counties. The finding showed that growth of population nor density of population do not have correlation to the normalized number of children’ fatality as well as unrestrained occupants involved in fatal crashes. It is recommended to use proper restraint system especially children in order to protect them from fatal injury. Additional research on how parents are getting educated or guided to use proper child restraint system in Texas counties is also recommended.
