Mumbai Coastal Road Introduces India’s First Musical Road

Rumble Strip Engineering Creates ‘Jai Ho’ Driving Experience

Mumbai has unveiled a distinctive traffic feature on the Mumbai Coastal Road , described by civic authorities as India’s first “musical road.” The installation transforms a routine driving surface into an audio-feedback mechanism, combining novelty with behavioural nudging for speed regulation.

Location and Design

The musical section is positioned on the northbound carriageway connecting Nariman Point to Worli. It begins shortly after motorists emerge from the Worli tunnel. Importantly, the grooves are restricted to a single lane adjacent to the divider, covering approximately 500 metres. This lane-specific configuration minimises interference with broader traffic flow.

Mechanism Behind the Music

The sound effect arises from carefully spaced rumble strips. As tyres pass over the grooves at the target speed band of 70–80 kmph , controlled vibrations generate rhythmic sound pulses. When synchronised correctly, these pulses form a recognisable melody audible within the vehicle cabin. The chosen tune for this stretch is ‘Jai Ho’ , internationally known from cinematic and award contexts.

Speed-Linked Behavioural Cue

The system functions effectively only within a defined velocity range. Deviations distort the melody, indirectly encouraging drivers to maintain steady speed rather than accelerate or decelerate abruptly. Advance signage inside the tunnel alerts motorists, ensuring lane awareness and reducing surprise.

Broader Implications

Musical roads have appeared in countries such as Japan and South Korea, typically as experimental safety or engagement tools. Mumbai’s adoption introduces discussions around driver attention, distraction potential, and lane discipline on high-density urban corridors.

Exam-Focused Points

• Rumble strips: Grooves producing vibration and sound alerts.

• Target speed for musical effect: 70–80 kmph .

• Installation length: ~500 metres .

• Musical roads used internationally as novelty-safety hybrids .

• Mumbai Coastal Road: Major urban mobility corridor.
