In order to simulate congestion of road traffic simulation system, it is indispensable to describe vehicles having their own decission-making capabilities, and to have detailed and correct road condition data on road system. We propose a new object-oriented road model for the road data on road system to carry out its simulation. The road model is composed of two (sub-) models; road network model and track model. The road network model includs the attributes such as their varying widths, shapes, slopes, traffic lanes and their channel. This model is described based on a combination of straight lines, circles and clothoid curves. Track model is described by the concept of pseudo-lanes in addition to traditional lanes. Concept of this model similar to one of the railroad tracks. The road model is able to represent vehicles' run within errors in the range of 50 cm. Moreover, it is able to carry out exactly, speedily and effectively the road traffic simulations. We have successfully carried out several simulations to verify the road model. This paper described the concept, functions and performances of our road model, and verification of it.
