More than 1.87 lakh new vehicles were added to the city roads last year, bringing the total to 22.21 lakh, data from the motor vehicle department has revealed.
The document records more than 14% increase last year as compared to the 1.63 lakh vehicles registered in 2011-12.
Interestingly, the number of car registrations has decreased by 4%, but those of two-wheelers went up by 22%.
According to regional transport officials, the registrations of two-wheelers went up from 88,399 to 1.08 lakh, while those of four-wheelers dropped from 60,601 to 58,136.
The remaining vehicles registered included three-wheelers, trucks, school buses and ambulances.
Officials said, the highest number of registrations was in the western suburbs (89,364), followed by the island city (50,339) and the eastern suburbs (47,334).
Blaming the economic slowdown for the drop in the sale of four-wheelers, a senior regional transport official said most salaried people are now opting to purchase bikes and scooters as they are more affordable.
Transport expert AV Shenoy said, "Traffic jams, congestion, poor public transport system and increase in fares of autorickshaws, taxis, trains and buses are also
contributing to the rise in use of two-wheelers. But, I think, this will only worsen the traffic on city roads, as most two-wheeler riders don't follow the rules."
