South Bengaluru traffic drops 37% after yellow line metro; Tejasvi Surya calls it proof of mass transit power

The opening of the R.V. Road–Bommasandra Yellow Line has significantly decongested South Bengaluru’s busiest roads, easing bottlenecks and making traffic management smoother.

Bengaluru’s Yellow Line Metro, connecting R.V. Road to Bommasandra, has dramatically changed the traffic landscape in the city’s southern corridor. Since its launch, congestion on this busy 19.15 km stretch has fallen by 38% during weekday morning peak hours and 37% during evening peak hours. Overall weekday congestion dropped by 30.6%, while non-peak hours saw a 17% decline.

The impact is even more visible on weekends. Morning peak-hour congestion is down by 69% and evening peak by 39%, with a massive 58% reduction during non-peak hours. The Yellow Line’s reach has significantly decongested key junctions like BTM Circle, Silk Board Junction, Hosa Road, and Electronics City, all of which have long been notorious for gridlock.

Smaller connecting roads have also benefited from the decline in traffic density, easing hyper-local bottlenecks and allowing smoother traffic management. This has been a relief for the Hosur Main Road and Madiwala junction, a critical hub for inter-State buses, where vehicle movement has improved noticeably.

Interestingly, Wednesdays remain the most congested weekday, though peak congestion has dropped sharply from 37.02 km to 26.79 km in the mornings and from 64.10 km to 40.67 km in the evenings. However, Monday and Wednesday non-peak hours have seen a slight 25% and 21% rise respectively.

The Yellow Line was inaugurated on August 10 and opened to the public the next day after a four-year delay. Initially, the line ran with three train sets, causing long headways of 25 minutes. On September 10, BMRCL introduced a fourth train set, reducing the interval to 19 minutes and easing station crowding. More trains are expected soon, further improving frequency and reducing congestion across the city.

Tejasvi Surya highlighted the milestone in his X account, noting that a 37% drop in congestion with just four trains at 19-minute intervals proves that mass public transport is Bengaluru’s most effective traffic solution. He stressed that increasing frequency and prioritising Pink and Blue Line construction would yield even greater benefits, urging the state government to focus on public transport rather than vanity projects.

A massive 37% drop in congestion after the launch of the Yellow Line Metro showcases yet again how mass public transport is the most effective solution for easing traffic congestion in Bengaluru.

And this is with just 4 trains running at a 19-minute frequency.
