Road transport ministry proposes to install crash barriers at accident prone locations in hilly terrains

PUNE: The ministry of highway shipping and highways has made up our minds to put in crash boundaries at coincidence susceptible locations on national highways in hilly terrains.

The ministry be aware mentioned, "crash boundaries of appropriate type are put in at coincidence susceptible locations particularly at locations like valley sides of hilly roads, high embankments, and sharp curves. These are very useful in absorbing have an effect on power of the hitting automobiles and decreasing the severity of the accidents. The boundaries must contain the impacting automobiles and redirect them without permitting the crash boundaries penetrating in to the automobiles or permitting the automobiles to volt over the crash boundaries. When the vehicle hits the crash barrier, it must no longer deflect for a distance greater than the gap available for the deflection''.

The Modified Thrie beam crash boundaries (semi-rigid) is the most appropriate for hilly areas. In this crash barrier, a few modifications have been made compared to standard thrie beam type boundaries by way of increasing the spacer channel dimension compared to the put up dimension leaving the lower edge of the thrie bream unconnected to the spacer channel and offering huge notch lower to the web of the spacer channel at the lower end. These modifications progressed the performance of the crash barrier by means of conserving the deflection lower and conserving the vehicle upright even after the have an effect on.
