Abstract
In urban traffic, there are situations where cars parked on the road shoulder or part of the roadway obstruct the view to other road users. That situation can lead to a road incident with various consequences. This article presents sample consequences of a road incident that occurred due to one driver failing to give way by moving his or her car too far forward to make sure they could continue the drive. A total of four scenarios were analysed, assuming two different car positions before the accident and two different driving speeds. The reconstruction of road incidents was conducted with the use of the V-SIM 6.0 software licensed by CYBID Kraków, Poland. In addition, the number of road incidents at five selected crossroads in the consecutive quarters of the year was forecast using the grey system theory.
The simulation results demonstrated that moving the front of the car that gave way by up to 1.25 m beyond the roadway centre line and the other car’s driving speed of 60 km/h will lead to the most serious consequences of the accident. The maximum volume of car silhouette coverage in that case will be 0.38 m3. The forecast of the number of road incidents at the four crossroads in the next four quarters will demonstrate an increase in the number of accidents if relevant procedures are not implemented to improve visibility of the situation on the road at these locations.
