IISc Report Says Hebbal Tunnel May Shift Bengaluru Traffic Chaos
A study from the Indian Institute of Science looked at a planned tunnel in Bengaluru.
It says the tunnel may not make traffic disappear.
Instead, cars could get stuck at other nearby places.
Traffic lines might also stretch back toward Mekhri Circle.
The study says the tunnel could eventually become almost useless.
It also warns that the project may cause flooding.
The report compared the tunnel with an underground metro.
It found that the tunnel would cost much more for each passenger or unit of capacity.
An IISc study says the proposed short tunnel at Hebbal Junction may relocate rather than solve congestion.
The report identifies possible new bottlenecks near the Veterinary Hospital and Esteem Mall.
Traffic spillover could push queues toward Mekhri Circle and eventually reduce the tunnel’s usefulness, the study says.
The study warns the project may also lead to flooding.
The report’s cost-benefit analysis says the tunnel costs about 6.12 times more than an underground metro for comparable benefits.
- Who
- The Indian Institute of Science Sustainable Transportation Lab, led by Professor Ashish Verma, conducted the study.
- What
- The study assessed the proposed short tunnel at Hebbal Junction and concluded that it may shift congestion, create flooding risks, and cost more than an underground metro.
- Where
- Hebbal Junction in Bengaluru, with possible effects near the Veterinary Hospital, Esteem Mall, and Mekhri Circle.
- When
- The study was released on Tuesday; no calendar date is provided.
- Why
- The study examined whether the tunnel would reduce congestion and provide value compared with an underground metro.
