  7. Abstract:
  8. Freight transportation by trucks plays a critical role in economic development and shaping human life. A significant portion of the total and operational costs of countries is accounted for by transportation, and efforts to optimize it have always been considered of utmost importance. One of the emerging technologies aimed at transforming traditional transportation is vehicle automation. Due to its more uniform nature compared to urban transportation, road freight transportation has greater potential for adopting this technology. Numerous studies have addressed this issue; however, the assumption of fixed variables and the lack of an optimal program for the gradual transition from non-autonomous to autonomous systems motivated us to conduct this research to address these questions. Initially, we reviewed available information from various sources related to the transportation geography of Iran. Due to data insufficiencies, we designed questionnaires to collect necessary data from experts. Subsequently, we reviewed and processed the collected data to define uncertain variables. Thereafter, we established the logic and assumptions necessary for defining the network using the questionnaire responses and constructed the intended model in the AnyLogic simulation software. We then performed the necessary experiments, including comparative runs, optimization, and sensitivity analysis, to obtain and analyze the model outputs. The most significant findings of this research are the output chart of transportation costs in terms of dollars per ton-kilometer, which illustrates the oscillatory nature of the total transportation costs for the system based on automation percentages. Furthermore, we examined the performance of a system that integrates both autonomous and non-autonomous trucks. The hypothesis that the overall system cost decreases with automation was also questioned based on these results at certain automation percentages of the system
