There are several promising applications for car-to-x communication that aim at the improvement of traffic efficiency. With the increasing maturity of car-to-x communication systems, insights into the impacts of these applications on vehicular traffic are required. In this paper, the authors present a simulation study of traffic efficiency improvements that can be obtained by the utilization of a merging assistance application ahead of a freeway lane drop. Their investigations are based on the traffic simulation tool AIMSUN (Advanced Interactive Microscopic Simulator for Urban and Non-Urban Networks). The authors connect the traffic simulator with a simulation model that implements the merging assistance application as well as the message exchange between vehicles and a roadside unit. Simulation results show significant traffic efficiency improvements indicated by travel time reductions of up to 30 % in dense traffic under ideal conditions. The paper is organized as follows: After an overview of relevant traffic engineering concepts in section 2, the authors outline the traffic simulator and the reference scenario in section 3. Section 4 presents the communication model and the merging assistance application they developed as well as the simulation results and finally section 5 contains a short conclusion and an outlook.
