India's first smartcard based public bicycle sharing (PBS) initiative "Trin Trin" was launched in which city?

Introduction / Context:
Public Bicycle Sharing (PBS) systems are eco friendly transport solutions that encourage people to use cycles for short trips. When such a system is integrated with smartcards and docking stations, it becomes an important urban innovation. The initiative called “Trin Trin” is recognised as India's first smartcard based PBS system, and this question asks you to identify the city where it was launched.

Given Data / Assumptions:

• The scheme is named “Trin Trin”.
• It is described as India's first smartcard based public bicycle sharing initiative.
• The options are four locations: Chennai, Mysuru, Bangalore, and Goa.
• We assume the question refers to the official launch of this system in Karnataka.

Concept / Approach:
“Trin Trin” was launched in Mysuru (Mysore) in Karnataka as a joint initiative of the state government and local authorities, with assistance from international agencies. Users can take bicycles from docking stations using a smartcard and return them to any station. Remembering the distinctive name and associating it with Mysuru is the key to answering correctly.

Step-by-Step Solution:
Step 1: Focus on the brand name “Trin Trin” and recall any city level bicycling initiative with that name. Step 2: Remember that “Trin Trin” was launched in Mysuru, which is known for its heritage and as a pilot city for sustainable transport projects. Step 3: Compare this recollection with the options: Chennai, Mysuru, Bangalore, and Goa. Step 4: Select “Mysuru” as the correct answer.

Verification / Alternative check:
Another way to verify is to recall that Bangalore (Bengaluru) is associated with many tech initiatives but the first full fledged smartcard PBS system with the brand “Trin Trin” was specifically inaugurated in Mysuru. Some exam capsules explicitly mention “Trin Trin – Mysuru – First smartcard based PBS in India”.

Why Other Options Are Wrong:

• Chennai: Although it has urban transport projects, it was not the city that launched the “Trin Trin” system.
• Bangalore: Known as the IT capital of India, but the named PBS initiative in question was launched in Mysuru.
• Goa: Popular for tourism, but not associated with this specific smartcard based cycle sharing scheme.

Common Pitfalls:
Students sometimes assume that any modern transport initiative must be in Bengaluru or a metro city, and therefore incorrectly choose Bangalore or Chennai. To avoid this, pay attention to the actual cities mentioned in your current affairs notes; smaller cities like Mysuru are often chosen as pilot locations for innovative projects.

Final Answer:
The “Trin Trin” smartcard based public bicycle sharing initiative was launched in Mysuru.
