Focusing on the traffic flow where motorcycles and passenger cars are mutually mixed, this study developed the indices for the safety and efficiency of the mixed traffic flow. Based on the indices, the influential factors on safety and efficiency was analyzed. As a result, it was revealed that segregating motorcycles from passenger cars spatially might be effective to improve the safety of the mixed traffic flow. In terms of the efficiency, it was effective to segregate motorcycles from passenger cars by making the motorcycles exclusive lane in developing countries where road infrastructure was not in good condition and traffic was rather chaotic, while in developed countries the advantage of the space segregation policy was limited. Rather, it was revealed that the time segregation policy, where motorcycles were temporally segregated from passenger cars by varying the timing of green light at signalized intersections, could be more efficient.

针对摩托车和乘用车相互混合的交通流，提出了混合交通流的安全和效率指标。在指标的基础上，分析了影响安全和效率的因素。结果表明，在空间上将摩托车和乘用车分开，可能会有效地提高混合交通流的安全性。就效率而言，在道路基础设施状况不佳、交通相当混乱的发展中国家，通过使摩托车成为专用道，将摩托车与乘用车分开是有效的，而在发达国家，空间隔离政策的优势有限。相反，据透露，通过改变信号交叉口绿灯的时间来暂时将摩托车与乘用车分开的时间分割政策可能会更有效。
