Vehicle-type Dependent Car following Model Using Spring-mass-damper Dynamics for Heterogeneous Traffic

Although traffic modellers consider driver-vehicle as a single unit to describe the driving behaviours, it is important to understand that the type of a vehicle dictates many a times how a driver should or shouldn’t behave. Most importantly, it is the weight of a vehicle as well as its engine characteristics that affect the vehicle acceleration which in turn affects the driving behavior. This aspect of vehicle-type dependent driving behavior is more significant in heterogeneous traffic conditions prevailing in developing countries like India, China, Indonesia, Bangladesh, and the like due to the presence of multiple vehicle types. Thus, a vehicle-type dependent car following model is proposed in this paper using the dynamics involved in spring-mass-damper mechanical system. The component of ‘mass’ present in the spring-mass-damper system inherently replicates the ‘vehicle-type’. The proposed model when tested, behaved pragmatically in representing the vehicle-type dependent car following behavior.
