Center node: "a right of way assignment strategy to ensure traffic safety and efficiency in lane change"
  Abstract: How to guarantee absolute safety and meanwhile maintain traffic efficiency remains difficult for intelligent vehicle studies. This paper discusses how to deal with these two problems in lane change scenarios. Its key idea is to develop a right-of-way assignment strategy for clear collision avoidance conditions. Both theoretical analysis and numerical testing results are provided to show the effectiveness of the proposed strategy. Experiments demonstrate that this new strategy is not only collision-free as the so-called Responsibility-Sensitive Safety (RSS) strategy but also increases traffic efficiency.
