I started to research the trends in this area to answer the first question of my study. The first question in my research is What are the trends of the purpose to use smartphones to capture driving behaviour using machine learning techniques? I critically formulate the queries in Google Scholar to collect the publication data between 2012 and 2022. I decided to choose the top 10 that most related to the study project, this is the result:

 

Every query was taken the number of publications for every year between 2012 – 2022

                           

These trends, in general, show an important increase from 2016 in general, but Machine learning and Road safety have increased over the last 5 years and machine learning and driving behaviour follow the same trend. Another significant trend is machine learning and intelligent transportation system query tend to continue increasing, it has a slight curve indicating that research in this area is becoming crucial. While driving behaviour and smartphone has constantly increased over the last 10 years. I believe that intelligent transportation systems including smartphones as an integrated part will become an as important part of society.

I decided to see some relevant sectors around transport, I should see more sectors, but Transportation has been increasing before the pandemic. This sector has similar behaviour to machine learning and road safety, I can conclude that since WHO has been pursuing a systematic approach to the issue of road safety and launched the decade action to reduce accidents, the research has increased to support this program. Now the new decade program to cut down on traffic-related fatalities & injuries by at least 50% will increase the research around Intelligent transportation systems looking for alternatives to integrate into this system such as driving behaviour analysis using smartphones.
