| Abstract | Car-following theory has been proved very useful in exploring the behavior of how drivers follow each other on the roadway without passing condition. Between consecutive vehicles the major contributing factors which influences on the response of followers are relative speed, inter-vehicle spacing and driving speed including the time lag between the response and stimulus. The stimulus can be referred to an alteration of inter-vehicle spacing that drivers can perceive while the inter-vehicle spacing and the driving speed level govern the sensitivity. The aim of this thesis is to propose modified model and identify the causes of variation in model parameters. The experiment was conducted on the test track by using ten-car platoon with the pre-determined speed of the first leader. It is found that the model that includes second leading car, excess critical speed and acceleration of the leading vehicle can dominate the conventional model. The reaction time values are significantly different for acceleration and deceleration and they greatly influences on the model parameters as well. Finally it was found that the reaction time is substantially shorter when the drivers are concerned more about the headway and their driving speed, particularly in deceleration phase. |
