Extra Width Required on Two-Lane Pavement for a Radius of Curve 100m
In the field of transportation engineering, the width of a roadway is a crucial factor in ensuring safe and efficient traffic flow. When it comes to curves on a two-lane pavement, additional width is necessary to accommodate the additional space required for vehicles to traverse the curve safely. The Indian Road Congress (IRC) has provided guidelines for determining the extra width required on two-lane pavements for different radii of curves.
IRC Recommendations
According to the recommendations of the Indian Road Congress (IRC), for a radius of curve of 100m, an additional width of 0.9m is required on two-lane pavements. This extra width is necessary to ensure the safe movement of vehicles around the curve without encroaching into the adjacent lane.
Justification
The extra width required on a two-lane pavement for a curve depends on various factors, including the design speed, lane width, and the radius of the curve. As the radius of the curve decreases, the vehicles need more space to negotiate the curve without crossing into the opposing lane.
The IRC guidelines take into account the sight distance requirements for the curve radius of 100m and recommend an additional width of 0.9m. This extra width provides a buffer zone for vehicles, allowing them to maintain their lane positions comfortably while negotiating the curve.
The additional width accounts for the lateral displacement of the outer wheels of the vehicles as they follow the curved path. It ensures that the inner wheels of the vehicles do not encroach into the adjacent lane, reducing the risk of collisions and improving the overall safety of the roadway.
Conclusion
In conclusion, the extra width required on a two-lane pavement for a radius of curve 100m, as recommended by IRC, is 0.9m. This additional width ensures that vehicles can safely negotiate the curve without encroaching into the opposing lane. Adhering to these guidelines helps in designing and constructing roadways that provide optimal safety and functionality for road users.
