Jaipur: Once considered the lifeline of Jaipur’s public transport network, the city’s mini buses are increasingly drawing concern over passenger safety and air pollution. Several of these vehicles can be seen plying with damaged bodywork, visible wear and tear, and, in some cases, emitting thick black smoke.Despite their deteriorating condition, thousands of commuters continue to depend on them every day. With the number of low-floor buses under the Jaipur Smart City project remaining limited and fares nearly half those of other public transport options, mini buses remain the most affordable choice for many residents.Mini bus operators say the problem has been mounting for years. Rajasthan City Mini Bus Association president Prashant Meel said fares have not been revised in the past eight years despite a steady increase in diesel prices and maintenance costs.“Before Covid, mini buses were Jaipur’s lifeline. Around 2,500 to 3,000 mini buses operated across the city from 6am to 11pm. Today, only 700 to 800 buses remain on the roads. The number of vehicles dropped sharply after the pandemic, and many buses now operate only when there are enough passengers,” Meel said.He said operators were not unwilling to maintain their vehicles but were struggling financially.“A single bus requires maintenance worth lakhs of rupees every year. When fares have remained unchanged for eight years and fuel prices have continued to rise, it becomes extremely difficult for owners to invest that kind of money in upkeep,” he said.Regional transport officer (Jaipur-I) Rajendra Singh Shekhawat, however, said mini bus operators already enjoy significant concessions.“These services exist for public convenience. While Rajasthan Roadways buses pay a monthly tax of Rs 10,000 to Rs 12,000, mini buses pay only Rs 350. That is why there is no proposal to increase fares. Even then, some operators charge more than the approved fare, and action is taken against them,” he said.On concerns over vehicle fitness, Shekhawat said the dept has written to the state govt seeking a reduction in the operational life of mini buses from 15 years to 10 years.“After June 15, we will launch a special drive. Any bus found in poor condition will face penalties and will not be allowed on the road until it meets fitness standards,” he said.
