Car Following Analysis Using DGPS Data Focusing on GM1 Model

This paper estimated GM1 model parameters using DGPS data of probe vehicles on a multilane motorway in Korea. Applications of this research can be seen in traffic simulation models, such as CORSIM and Paramics that use car following models to simulate traffic flow and predict operational performance characteristics on roadways. The GM1 model parameters calculated in this study were compared with those of the some existing studies. As a result of the comparison, the sensitivity (α) was much higher than the existing ones and the reaction time (T) was similar to them. Even though the parameters, estimated in the research exploited limited car following data, it could be highly regarded as the first case in which GM car following model parameters were estimated through DGPS data on the real highway in Korea.
