General overview of first-class main roads

General overview of first-class main roads 6.3.1. Design characteristics 

The Hungarian road network can be divided into two major categories the national (31,833 km) and the municipal road network (approximately 170,000 km). The national road network can be further divided into two major subcategories main perfumed consisting of motorways, express roads, first-class and second-class roads and minor (or secondary) roads. In this paper our safety performance analysis has been performed for the rural sections of the first-class main roads, and therefore the following criteria and figures apply to this road categoiy. 

The length of the first-class rural main roads in Hungry is 1,659 km, which is 29% of the total rural main road network and 8.6% of the total rural road network. Dne to the continuous expansion of the limited access road network, almost 80% of the first-class main roads have a parallel motorway or expressway, so the traffic volume in this road category is moderate (the AADT on these roads is roughly 7,500 vehicles/day on average). 

A few selected criteria according to design standards are listed below
