The Research of the Driver Attention Field Modeling

For expanding the application scope of car-following, based on the basic idea of the noncontact interaction of the objects in physics, establish an attention field model to describe the driving behavior. Firstly, propose the time distance concept to describe the degree of driver perception to the front one-dimensional space and extend its application range to the two-dimensional space. Secondly, connect the point which has the same time distance to constitute the equipotential line of drivers’ attention field equipotent, and establish a model to describe it. Thirdly, define the effective range of the driver’s psychological field with the feature of the driver’s visual distance range increasing and the angle decreasing. Finally, design the calculation method to collect projection of the object in the psychological field scope and calculate the curve points to determine the object’s intensity of psychological field. Preliminarily build the driving behavior model and use the numerical simulation method to simulate the simple transport scenarios; initially verify the validity of the model. 1. Introduction The research on the driving behavior has been the focus in the traffic engineering study. The driving behaviors model establishes a link between the characteristics of the single vehicle and the traffic. It explains the macrotransport phenomena from the moving of the microindividual and makes the development of the traffic flow theory. The driving behaviors model has important applications in the field of traffic simulation, traffic safety, and intelligent driving. The car-following model is the main form of the model driving behavior. Car-following model was used to describe the driving behavior of following vehicle facing the actions of the leading vehicle in the single lane with limit of overtake. It played an important role in the traffic theory and was widely used in the fields of microscopic traffic simulation, smart driving, traffic safety, and so forth. The researches of car-following have been lasting for years and made a series of results [1–3], and the GM car-following model was proposed firstly and considered the most classic model in those research results [4, 5]. This model regarded the difference between the leading and following car as the source of stimulation and combined with the space headway and velocity to obtain the driver’s acceleration decision making [6–9]. A variety of car model were from derived; the GM modeling idea [10–13]. Lee proposed a GM model with memory effect; the basic idea was that the driver react relied on the
