Decision & approval

The Karnataka Cabinet has approved a plan to install adaptive traffic signals across 110 junctions in Bengaluru, with a budget allocation of ₹56.45 crore.
The plan also includes five years of operation and maintenance of the system.

What are adaptive traffic signals / features

Adaptive traffic signals adjust signal timings in real time, based on traffic flow data from sensors and cameras, rather than fixed schedules.
Under this scheme, signal timings at those 110 junctions will vary dynamically to optimise traffic movement, reduce congestion, and improve vehicle throughput.

Rationale & objectives

Officials say the move aims to ease Bengaluru’s notorious traffic congestion and reduce travel times.
The dynamic adjustment is expected to respond better to changing traffic loads such as peak hours, off-peak periods, and sudden surges.
Over time, it may also reduce idling, emissions, and improve road safety by ensuring smoother flows.

Implementation & maintenance

The Cabinet’s approval also covers the five-year operation & maintenance of the system.
This includes hardware, software, sensors, repairs, and system upgrades.
The pilot or rollout will begin with those 110 junctions, with expansion to more junctions likely depending on results.

Challenges & considerations

  • Cost & funding: ₹56.45 crore is a substantial investment; ensuring proper allocation and oversight will be key.
  • Technical readiness: Sensors, communication networks, data analytics, and system reliability are critical.
  • Coordination: Multiple agencies including traffic police, municipal authorities, and IT/transport departments must work together.
  • Public adaptation: Drivers used to fixed timings may need time to adjust to dynamic changes.
  • Maintenance burden: Ensuring system uptime over five years will require commitment and regular upgrades.

Status & timeline

With Cabinet approval in place, procurement and implementation phases will begin.
The project’s success will be monitored over the initial few months, with room for modifications or expansion.
No specific dates for rollout or phase-wise implementation were provided.

Conclusion

The Karnataka government’s endorsement of adaptive traffic signals for 110 junctions in Bengaluru marks a technologically progressive step toward smarter urban mobility. If well executed, it could help mitigate congestion and improve traffic efficiency. But success will depend heavily on execution, maintenance, and interagency coordination.
