| Summary: | Abstract A method of designing roads, based on Arctic territories is described. Results of GPS-shooting are used for consideration of effect of sun blinding (SBE) of drivers and determination of dangerous because of sun sectors of road. Design of the road is held in special original software. When the road plan is designed, they consider SGE as a choice of such an azimuth of a road, within which the period of SBE would be minimal. Derivation of a road plan takes into consideration azimuth and meridian of specific road sectors in the Arctic. Geodesic position of main points of a road is specified on the basis of GPS-shooting. Azimuths of straight sectors of a road are calculated upon the points mentioned above. Apart from direction of the road azimuth, longitudinal slope, latitude and longitude of road track effect SGE. Introduction of given variables values is taken into account by the software to adjust the date and time of SGE on the surveyed section of the road. The values of all azimuthal coordinates are set in degrees and minutes in specially designated text fields under each graph. The aim of the method is to increase road safety, taking into consideration reduction of the negative impact of solar glare on the driver’s visual organs, which reduces visibility distance and attention-shifting; narrows eyeshot, etc. Under SBE conditions, the driver focuses on a small field of vision located in the course of movement and ignores outlying information. The method takes into account all the factors affecting driving of a vehicle in the conditions of SBE. Application of the method of astronomical design allows to develop operational measures to reduce the accident rate in sun-hazardous areas. |
