Conceptual Structure of a Novel Car-following Model Upon Gravitational Field Concept

This paper presents the conceptual structure of a novel car-following model basing upon the gravitational field concept, called gravitational car-following model. The concept is to describe the car following behavior using a series of forces of the attraction and repulsion related to the vehicle and spaces surrounding in front of the car. The gravitational car-following model consists of the lateral motion module as well as the longitudinal motion module under taking into account the car-following space to the front vehicle and lateral space to the adjacent vehicles nearby. The lateral motion in lane changing can also describe by the same model using gravitational concept. In the model the space in front the vehicle will be seen as a gravitational field. There is a pseudo mass, called mass equivalent, which is created to attract the vehicle moving ahead. Through the field observation, the parameters of the model can be calibrated. The model is then verified to be suitable to describe the real car-following behavior preliminarily.
