It comprises construction of 5,846-km long 4/6 lane, high density traffic corridor, to connect India’s four big metro cities of Delhi-Mumbai-Chennai-Kolkata. With the construction of Golden Quadrilateral, the time, distance and cost of movement among the mega cities of India will be considerably minimised.

1. Connected cities and its people on the route:
  - This point suggests that the transportation route (perhaps a road or railway) connects different cities along its path, facilitating mobility and connectivity. It implies that the project has a positive impact on urban and regional connectivity, bringing people and communities closer.

2. Reduced time, distance, and cost of movement on the route:
  - This point highlights the potential benefits of the transportation route, indicating that it leads to reduced travel time, shorter distances, and lower costs for movement. This is a common goal in transportation infrastructure projects, aiming to improve efficiency and accessibility.

3. Increased accidents because of high speed:
  - This point raises a concern about safety, suggesting that the project, perhaps due to high-speed elements, might lead to an increase in accidents. Safety considerations are crucial in transportation planning, and measures are often taken to mitigate risks and enhance road or rail safety.

4. Enhanced good quality road network:
  - This point emphasizes the positive impact of the project on the road network, suggesting that it contributes to the development or improvement of high-quality roads. A well-maintained road network is essential for smooth and safe transportation, benefiting both passengers and cargo movement.

So, option 2 is the most appropriate benefits of Golden Quadrilateral ?
