IIT-B Study Backs Hebbal Tunnel Project; IISc Disputes Findings
बातमीत का?
13.74 to 20.64 kmph, yet IISc calls it biased: Hebbal tunnel and GS-III urban transport
An IIT-Bombay study projected higher peak-hour speeds from the Hebbal tunnel project, but the IISc called the study biased.
Why it matters: Karnataka-specific

What you need to know
2 मिनिटे
An IIT-Bombay study estimated that the proposed Hebbal tunnel and flyover project could raise average peak-hour traffic speed on the existing road network from about 13.74 kmph to about 20.64 kmph by 2027, if half of traffic shifts to the new infrastructure.
The Indian Institute of Science (IISc), however, called the study 'biased in favour of the project', disputing its methodology and conclusions.
The disagreement between the two institutions has added to the public debate over the tunnel's necessity and design.

महत्त्वाची तथ्ये
Remember these
- IIT-Bombay study: peak-hour speed on the existing road network could rise from about 13.74 kmph to about 20.64 kmph by 2027
- The projection assumes half of the traffic shifts to the new tunnel and flyover infrastructure
- IISc called the study 'biased in favour of the project', disputing its methodology and conclusions
- The project is the proposed Hebbal tunnel and flyover in Bengaluru, Karnataka
- Syllabus link: GS-III Infrastructure, urban transport planning

How the exam will ask it
पूर्व
- An IIT-Bombay study projected that the Hebbal tunnel and flyover project could raise average peak-hour speed on the existing road network from about 13.74 kmph to about 20.64 kmph by 2027.
- The projected speed gain depends on the assumption that half of the traffic shifts to the new infrastructure.
- The Indian Institute of Science (IISc) disputed the study, calling it biased in favour of the project, rather than endorsing it.
मुख्य
GS-III (Infrastructure) and GS-II (urban governance): Bengaluru's congestion has prompted large road-capacity projects like the Hebbal tunnel, but rival expert studies from IIT-Bombay and IISc disagree on the benefits. The implication is that projections resting on assumptions such as a 50% traffic shift need independent, transparent scrutiny. The way forward lies in independent audits, public release of traffic models, and prioritising public transport and demand management alongside road projects.
Quick recall
Answer before you reveal
With reference to the Hebbal tunnel and flyover project in Bengaluru, consider the following statements:
- An IIT-Bombay study estimated that the project could raise average peak-hour speed on the existing road network from about 13.74 kmph to about 20.64 kmph by 2027.
- The Indian Institute of Science (IISc) endorsed the IIT-Bombay study's findings without reservations.
Which of the statements given above is/are correct?
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
उत्तर पहा
उत्तर: A — Correct: 1 only — the IIT-Bombay study projected peak-hour speeds could rise from about 13.74 kmph to about 20.64 kmph by 2027 if traffic shifted to the new project; the IISc called the study biased in the project's favour, not an endorsement, making statement 2 wrong. • 2 only — wrong: statement 1 is true. • Both 1 and 2 — wrong: statement 2 is false. • Neither 1 nor 2 — wrong: statement 1 is true.
