摘要：A safe, efficient, and effective transportation system is essential for the growth and stability of the economy and the lifestyle of its inhabitants [1]. The effectiveness of the transportation infrastructure and service industry depends heavily on the ability to recruit and retain a highly skilled and qualified workforce.

Some of the reasons for these challenges include demographic changes in the workforce, competitive labor market, new technologies, and the overall demand on the transportation industry [3].
