Design Considerations For Roadside Safety
ABSTRACT
There has been tremendous growth is roadway travel in India in the last two decades. The developments of roadways have not kept pace with the increase in demand of travel. This has resulted in traffic congestion, delay, discomfort and increase in accidents. Proper planning, design construction and maintenance of roadways can reduce this accident.
Even if every reasonable efforts taken by highway engineers to design the highway facilities so that the vehicles stay on the road, motorists may continue to runoff the road. This could be because of various reasons – driver error, excessive speed fatigue of drivers leading to inattentiveness, reckless driving or driving under the influence of alcohol or drugs, which are beyond the control of the highway engineers. Often drivers leave the roadway to avoid collision with another vehicle or with fixed objects. Poor roadway geometry, Poor visibility in bad weather, poor pavement condition, inadequate drainage, substantial signing and marking. All these factors causes motorists to get off the road.. .
