Bengaluru’s traffic crisis is now consuming a measurable part of the school year for children travelling through the city’s eastern growth belt. A mobility study covering 42 schools along the State Highway-35 corridor found that the average school-bus journey rose from 92 minutes in 2024-25 to 112 minutes in 2026-27. Across a 200-day school year, that amounts to about 374 hours on the road—nearly 53 school days.
The finding is striking not because traffic delays are new to Bengaluru, but because it shows how congestion has moved from being a daily inconvenience to becoming part of the city’s education system. For around 40,000 schoolchildren and their parents in east Bengaluru, the school commute now absorbs time that would otherwise be available for classes, rest, play and family life. The numbers also expose a planning gap: the corridor’s population, schools, housing and workplaces have expanded faster than the roads and supporting infrastructure serving them.
The study by Inventure Academy used data from 42 schools, while GPS information from 61 school buses recorded an average speed of 9.2 kmph on the corridor. Some stretches fell to 6.4 kmph. In September, buses reportedly took up to 2.5 hours to cover only four kilometres on the Varthur-Gunjur stretch. About 60% of school-bus trips did not reach their destinations on time, with the evening return journey often becoming slower.
These figures matter because school transport is a particularly rigid form of urban travel. Unlike many office commuters, children cannot easily change their departure time, route or mode. Schools operate at fixed hours, buses serve multiple stops, and parents often depend on organised transport because of work schedules and the distance between residential layouts and campuses. When traffic becomes unreliable, the disruption is not limited to the road. It affects attendance, punctuality, examination schedules and the organisation of household time.
East Bengaluru’s congestion is a product of concentrated growth. The Varthur-Gunjur-Dommasandra corridor combines schools, residential layouts, technology-sector employment, construction activity and traffic moving towards the wider Whitefield area. Varthur, Gunjur, Dommasandra and nearby locations have attracted housing and jobs, but the road network has not expanded at the same pace. Roads designed for lower volumes now carry school buses, private cars, goods vehicles, construction traffic and other daily trips within the same narrow operating space.
This is the familiar pattern of Bengaluru’s expansion, but the SH-35 corridor makes the consequences unusually visible. Growth has not occurred around a fully coordinated transport network. Instead, new housing and institutional uses have been added to a corridor where junctions, road widths, utility networks and construction schedules remain incomplete or constrained. Each new development may be locally approved or economically useful, yet the combined demand places pressure on infrastructure that is planned and delivered in separate administrative and project cycles.
The result is a road system in which one bottleneck can affect an entire school commute. A narrow stretch, a work zone, a pothole, a junction conflict or a delayed utility shift can reduce speeds over several kilometres. The study’s finding that buses travelled at an average of 9.2 kmph, with some patches dropping to 6.4 kmph, indicates that the problem is not simply the number of vehicles. It is also the operating condition and continuity of the corridor.
The planned infrastructure response illustrates the difficulty. The Varthur elevated corridor was started in May 2019 and was originally scheduled for completion by November 2021. The Karnataka Road Development Corporation Limited has now set December 2026 as the latest completion target for the Rs 488-crore project. According to the report, land acquisition, right-of-way disputes, utility shifting, approvals and execution delays have slowed progress. The study assessed the project as roughly 12% complete.
That timeline is important because it shows why a project intended to relieve congestion can become part of the congestion story. When construction continues for years on an already stressed corridor, road space is affected before the promised capacity becomes available. Land acquisition and utility shifting are not peripheral administrative tasks; they determine whether transport infrastructure can move from announcement to usable service. A corridor’s transport performance therefore depends not only on its final design, but also on the institutions responsible for securing land, coordinating utilities, approving works and managing traffic during construction.
The elevated corridor also reveals the limits of treating congestion as a single-project problem. A flyover or widened road may address a particular bottleneck, but school traffic is distributed across entrances, junctions, local roads and turning points. Even if a major structure improves movement on one section, buses can still lose time at the approaches to schools, on narrow connecting roads or at unfinished stretches. The report’s account of persistent bottlenecks despite better traffic flow during periods of police enforcement and heavy-vehicle restrictions points to this network effect.
The response to the immediate crisis has therefore included measures that do not depend on the completion of the Rs 488-crore project. Bengaluru development minister Krishna Byre Gowda asked officials to prioritise pothole repairs and address delays in road works. Authorities also imposed restrictions on heavy vehicles during school hours. A subsequent ground report found improved traffic flow when police enforcement and restrictions were in place, but congestion continued at narrow sections and locations affected by patchy repairs.
These actions demonstrate the value—and the limits—of operational management. Police deployment, time-based vehicle restrictions and road repairs can improve conditions quickly because they target the way existing road space is used. They can be especially relevant during school peaks, when several institutions generate demand at roughly the same time. But they do not create additional road capacity, resolve land acquisition, complete utility relocation or change the location of schools and housing. They are controls on a stressed system, not a substitute for coordinated infrastructure delivery.
Metro expansion is similarly important but cannot, by itself, resolve the specific problem documented on SH-35. The city’s Blue Line expansion and other Metro projects are under way, and residents have argued that mass transit would serve the area better than relying only on flyovers. A Metro system can move large numbers of passengers efficiently along its alignment. School buses, however, make dispersed trips between residential layouts and campuses, often along roads that connect to rather than sit directly on a Metro station. The bottlenecks around school gates, local junctions and incomplete roads would remain unless the wider access network is also improved.
This distinction is central to Bengaluru’s mobility debate. Metro, elevated corridors, road widening, traffic enforcement and local repairs are often discussed as competing solutions, but they operate at different scales. A high-capacity transit line addresses movement between major parts of the city. A corridor project addresses a defined road constraint. Police management handles short-term flows. Pothole repairs restore basic road performance. None can replace the others, and none can compensate indefinitely for growth that is approved without matching transport capacity.
The school-bus data provides a useful measure of that mismatch because it captures both the daily experience and the cumulative cost. A rise from 92 to 112 minutes represents an increase of about 22% in average daily travel time over two academic years. The annual total of roughly 374 hours translates a transport failure into a time burden that is easier to understand than a traffic-speed statistic. It also shows why congestion should be assessed through the reliability of essential journeys, not only through average vehicle speeds or the completion of large infrastructure projects.
The evidence supplied in the report does not establish that every cause of the delay has been quantified, nor does it independently assess the performance of each planned intervention. It does, however, connect three clear facts: the corridor has experienced rapid residential and employment growth; school-bus travel has become slower and less reliable; and the infrastructure response has been delayed. Together, these facts point to a governance problem in which urban expansion and transport delivery are moving on different timelines.
For Bengaluru, the larger question is whether future growth can be sequenced with infrastructure before congestion becomes a burden carried by the next generation. The immediate milestones are practical: whether pothole repairs and school-hour restrictions are sustained, whether narrow stretches are improved, and whether the Varthur elevated corridor meets its December 2026 target. Until those steps produce reliable movement, the 53-school-day figure will remain a measure of how the city’s growth is being paid for in children’s time.
