The Vehicle Actuated Control (VAC) system, recently deployed in Bengaluru, is intended to optimize signal durations by assessing real-time vehicle movement. However, many drivers remain uninformed about its functioning, resulting in confusion and potential hazards.

Previously, countdown timers at intersections helped motorists anticipate stoppages, allowing them to switch off their engines during long waits. With VAC in place, signal durations fluctuate unpredictably, removing that convenience and adding uncertainty. While the technology sounds promising, early feedback suggests significant drawbacks.

A commuter shared a harrowing experience of nearly colliding with a two-wheeler while attempting a right turn. The signal had turned green, but within moments, it switched back to red, leaving them stranded mid-intersection as opposing traffic surged forward. Alarmingly, there was no yellow light transition, increasing accident risks.

Several users have also complained about being stuck at signals for extended durations, sometimes exceeding five minutes. Additionally, some signals appear to shift into manual (MNL) mode, remaining green for one direction while others are left waiting indefinitely. This malfunction is particularly problematic during late-night and early-morning hours when no traffic personnel are present to intervene.

Though VAC was introduced to enhance traffic efficiency, its unpredictable behavior is causing frustration and safety concerns. Unless these glitches are resolved, Bengaluru’s commuters may find themselves battling not just congestion but also faulty technology.
