This paper proposes an approach to estimate the value of motorcycle equivalent units (MEU), which are very important for studies of motorcycle-dominated traffic flows. With some minor adjustments, the proposed approach can also be applied to car-dominated traffic flows. A model for MEU estimation was developed using real-world traffic data collected in Vietnam. The proposed model describes the relationship between MEU values and significant parameters such as trajectory, velocity, and safety distance. The MEU values estimated using the proposed model were compared with values estimated using previously proposed models. The results show that the MEU values estimated using the proposed model are quite stable and can be applied to many types of roadway geometries in developing countries.
