  7. Abstract:
  8. Nowadays, transportation has become one of the key elements of human social life, and this phenomenon has created several problems, including overcrowding, long travel times, and environmental deterioration, all of which have led to an increase in the necessity of finding novel solutions to resolve these predicaments. One of the suggested solutions is the use of autonomous and connected vehicles. This study focuses on the lane-less and direction-less movement of autonomous vehicles. The implementation of such a scenario is possible by relying on intelligent transportation systems, such as the synchronized connection of vehicles, which would reduce users' travel time and increase their capacities. The movement of autonomous vehicles in an environment without any lane separation and direction specification would create a complex situation that, in turn, makes the formulation and definition of this problem difficult. In this study, all of the related constraints, such as preventing vehicles' possible conflicts, attaining a suitable speed, and maximizing all of the networks' utilities, are considered by evaluating the transportation system's performance under three different scenarios using a mathematical model relying on agent-based simulation. Then, the results of the proposed model for a crowded and an uncrowded traffic link are compared with lane-based simulations conducted using the SUMO software to demonstrate the efficiency of the model in enhancing the traffic link’s capacity
