Gravel Roads Paving Program has been started since 1998, however, it was determinedthat after reconstruction 4.7 % of gravel road sections became potentially dangerous. Oneof the main disadvantages of this program is a slightly changed or entirely unchangedhorizontal alignment of roads. During the reconstruction the road pavement isstrengthened, the gravel surface is replaced by asphalt pavement. This enables toincrease the speed limit but based on design rules the design speed remains unchanged.Investigation of horizontal alignment of 30 regional roads was carried out in order toassess compatibility of the horizontal alignment elements and their correspondence totraffic safety. It was determined that compatibility of the horizontal alignment elements isfair, and the calculated operating speed v85 is 10–20 km/h higher than the design speed vd.It was also determined that compatibility of the horizontal alignment elements of lowvolumeroads in most cases is fair. Dynamic consistency of roads is poor. Analysis ofvertical alignment showed that the stopping sight distance meets the requirements in allthe elements of vertical alignment, whereas, the passing sight distance meets therequirements only in 8.2 % of all elements where the design speed v_d = 70 km/h.
