Pune: The Pune Mahanagar Parivahan Mahamandal Limited (PMPML) is considering a technical fix amid growing complaints from commuters to the problem of silent electric buses startling pedestrians and motorists by gliding past without any sound or warning.Senior PMPML officials said they would soon approach the Automotive Research Association of India (ARAI) to explore sound-based alert systems for the e-buses. The core issue lies in the lack of engine noise in electric buses, making it difficult for citizens to detect the movement, they added.ARAI director Reji Mathai said, “We have primarily developed the acoustic vehicle alerting system (AVAS) technology for electric cars, because regulations were in place for that. The technology is ready and can be used in e-buses too.”AVAS emits sound at specific frequencies and amplitudes to alert road users of an approaching EV. Although initially meant for cars, Mathai said it could be adapted for larger vehicles.He said, “It is not just any noise; it is of a particular frequency and amplitude. However, we cannot force anyone to buy our technology. One area we are seriously looking into is EV two-wheelers. At present, we are conducting a study with the industry to improve safety.”Former PMPML joint managing director Nitin Narvekar had earlier suggested initiating talks with ARAI to implement AVAS in Pune’s electric buses. “It will be good if PMPML’s e-buses can be equipped with the system,” he said.PMPML chairman and managing director Pankaj Deore said the plan is being reviewed. “I will study the plan and decide accordingly in this week,” he said.Currently, PMPML operates a fleet of 490 electric buses. However, concerns are rising — not just over silent operations, but also mechanical reliability. “The buses are risky,” said commuter Ashwin Lande. “They just zoom past without warning. Many new EV models include some form of audible alert now. PMPML should consider something similar.”Another commuter, Pankaj Khot of Kondhwa, echoed the concerns. “These buses often speed in heavy traffic and even break signals at night. If there’s a system to alert people, it should be implemented immediately,” he said.PMPML spokesperson Kishore Chauhan said drivers have been instructed to honk frequently, especially while overtaking. “The buses are operated by private contractors. We’ll investigate the complaints,” he added.(With inputs from Shashank Didmishe)
