The task of the comparative evaluation of the safety lighting poles installed around the road under the action hit them the car. Notes that studies on the calculation and modeling lighting poles when exposed to shock loads due to vehicle collisions is very small.
The situation of a conditional vehicle exit (LADAPRIORASEDAN) from the carriageway to the roadside is followed up, followed by a collision with a metal or reinforced concrete support for external electric lighting. Vehicle speed is 60 km/h and the calculation is performed by finite element method. Diagram shows the compressive forces, bending moments, shear forces, displacements.
The analysis found that by hitting the conditioned car to support the outer electrical lighting in a bearing of reinforced concrete arise effort close to being admitted that for small deviations from design parameters (e.g., speed limit is exceeded, possible defects and injuries of lighting columns) can lead to the collapse construction, including the possible fall of its vehicle.
Consequently, the support of the metal outer lighting when hit by the vehicle conditional security parameters and external lighting strength of reinforced concrete is preferred support.
