Description Due to the limited field of view of the driver on the secondary road safety assessment capabilities of performing the desired action of turning and crossing at the road intersections with unfavourable angles (< 70° and > 110°) becomes uncertain. Since all the intersections from the standpoint of traffic safety services must have sufficient sight distance at the road intersections with unfavourable angles it is common to perform reconstruction of the secondary road axis, so that main and secondary road axis intersects at approximately right angle.
This paper will present how sight distance tests based on measurements of the driver visual field from different types of vehicles (passenger car and heavy vehicles) were performed on the road intersections with unfavourable axis angles. Test results will show for which road intersection angles it is possible to keep the secondary road axis in the direction, without the need for reconstruction.
