The research design that was used to collect data in this research was multiple time series. The author of the article used the data that was collected from the cases that were recorded previously over a period of time. The data was sampled to come up with the results that formed the topic under study. The data that was used for the study was drawn from the collections by the Fatality Analysis Reporting System (FARS). The data gave clear information of the fatality cases that have been experienced on the highways of Tennessee in United States. The data was sampled on a monthly basis to find out to what extend the accidents were taking place. The data showed whether the numbers of such cases were increasing or reducing as the years went by. The sampling technique was done using specific variables that were related to the increased level of accidents. The sampling procedure was also based on the number of cases that were recorded before and after the use of emergency cellular phones.
The independent variable that was used for this research included the rate of beer consumption, the rate of unemployment and the rate of gasoline consumption. All this was done to identify how using cellular phones impacted on the program of minimizing accidents. The findings of the data revealed that the use of emergency cellular phones reduced accidents by a certain percentage. The emergency cellular phones were utilized by the police officers and other witnesses who had to report the occurrence of the accident for necessary action to be taken. However, these results could not be relied on due to certain limitations. There are certain changes that were made on Tennessee’s highway due to the reported accidents. It is hence not clear whether it was the use if cellular phones that minimized on the accidents or such improvement that were made. There was also no clear evidence to actually suggest that it was the use of such cellular phones that minimized on the accident. The research was mainly carried out before they started using it and results shown after. There could be other factors that improved the situation that were ignored by the research.
