Cyber-Physical technologies in freight operations and sustainability: A case study of smart GPS technology in trucking

Abstract

With the growing rate of urbanization, freight transportation systems have become critical in supporting economic and social needs in the United States. In order to achieve efficient and effective operations, freight transportation systems are recognizing the value of using Cyber-Physical (CP) technologies. This research provides a scenario-based assessment of CP technology penetration to improve sustainability in freight transportation systems with a focus on the use of smart GPS technologies by the trucking industry in Tennessee. Based on the case study, CP technologies can result in significant benefits to the economy, environment, and society. A cost-benefit analysis shows that benefits can be more than 7 times the costs in terms of present values. Social benefits can amount to more than $77M in the period of study when only 3 % of the truck population uses smart GPS technologies. Environmental benefits of 1 % CP technologies penetration in the truck industry are equivalent to GHG emissions savings from 46,930 passenger vehicles driven for one year. Benefits become more significant with higher penetration rates. For example, at 5 % usage rate of GPS technologies in the trucking industry in Tennessee, CO2 emissions will decrease by more than 1 million metric tons per year.
