| Research Abstract |
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.
