The public transport system of Bengaluru is plagued by delays and inefficiencies that have resulted in huge losses to BMTC, the operator, and lack of quality services to the common people. Now, scientists from the Indian Institute of Science have proposed a new model of transport that aims to increase bus efficiency, reduce or eliminate delays and save money for both the transport corporation and its users - the people. The new model, researchers claim, could be a win-win situation for both and could revive the appeal of public transportation.

This 22nd of March, on the occasion of World Water Day, Research Matters caught up with Prof MS Mohan Kumar, a Professor at the Department of Civil Engineering, Indian Institute of Science (IISc), Bengaluru. He is also the Chairman of the Indo-French Cell for Water Resources and an Associate Faculty at the Interdisciplinary Centre for Water Research (ICWaR) at IISc and an ex-Secretary of the Karnataka State Council for Science & Technology. Apart from his role at the institute, Prof. Kumar has also extensively worked with government bodies such as the Bangalore Water Supply and Sewerage Board (BWSSB), Karnataka Urban Water Supply and Drainage Board (KUWSDB) and Bangalore Development Authority (BDA).
In an effort to make water resources sustainable, the Ministry of Earth Sciences, India and the Natural Environment Research Council (NERC), UK have funded a new project “Upscaling Catchment Processes for Sustainable Water Management in Peninsular India” (UPSCAPE). It is a 3-year £2 million research project that is one of the three projects in India initiated under the ambitious Newton-Bhabha Sustaining Water Resources Programme. Six institutes have come together as partners in this project, of which the prestigious Indian Institute of Science, Bangalore, is the lead Institute from India. “The motivating factor of the Newton-Bhabha project is to ensure science reaches the society and benefits it”, says Prof. Pradeep Mujumdar, Chairman at the Interdisciplinary Centre for Water Research, Indian Institute of Science. He also leads the team of Indian scientists working on the UPSCAPE project in the Cauvery river basin.
In a collaborative study between the Indian Institute of Science (IISc), Bangalore, and the University of Twente, The Netherlands, researchers have designed a new algorithm for image recovery in Photoacoustic Tomography (PAT). PAT is an important non-invasive biomedical imaging technique where the optical contrast rendered by laser beams and the superior resolution of ultrasound waves are used to study biological tissues. The new algorithm works better with higher accuracy as compared to the conventional ones in use today.
One might think that driving a car in Bangalore can easily become a nightmare, thanks to the traffic! But a recent study by a team of researchers at the Indian Institute of Science, Bangalore, and M. S. Ramaiah Institute of Management, Bangalore have found that 62% of young adults in Bangalore aspire to own a car as soon as they can afford one. The team, lead by Prof. Ashish Verma from the Department of Civil Engineering, studied the attitudinal factors that influence car ownership decisions among urban young adults in a developing country like India.
In December 2015, Chennai witnessed massive floods killing about 400 people and displacing thousands. Now, researchers from Interdisciplinary Centre for Water Research (ICWaR) at the Indian Institute of Science, Bangalore, in collaboration with researchers from Indian Institutes of Technology (IITs), Madras and Bombay have assessed the flood related information in the public domain and data from secondary sources and carried out quick first level analyses to develop an understanding about possible reasons for the floods. They observed that the massive floods were a result of a combination of factors; high rainfall intensity, overflowing rivers, global climate drivers, unplanned urbanization, inadequate drainage system and upstream reservoir releases.
Measurement of Land Surface Temperature (LST) is important for hydrology, environment science and many associated fields. Prof. D. Nagesh Kumar of Department of Civil Engineering at the Indian Institute of Science, Bangalore, and his team have proposed a novel methodology that can accurately predict LST at high resolution even under cloudy conditions. Their work has been published in the ISPRS Journal of Photogrammetry and Remote Sensing.
A bicycle is budget friendly, being cheaper than most other forms of transport, eco-friendly requiring absolutely no fuel, does not need much of parking space, helps keep the chic city-dweller fit without having to shell out for monthly gym subscriptions, and requires a very low maintenance. Put like that, it sounds like an ideal mode of transport. And yet, for most of us having owned a bicycle during our childhoods, a cycle is only a symbolic reminiscent of the adventures of our junior years and nothing more.
Prediction of rainfall and flood is very important for densely populated country like India. Scientists at the Indian Institute of Science (IISc), Bangalore have proposed a new method for predicting flood magnitude, which is more effective than conventional methods. The team consisted of Prof. V.V. Srinivas and Dr. Bidroha Basu of Department of Civil Engineering.
India ranks lowest in terms of road safety. There is a need to scientifically analyse the factors causing road accidents and come up with guidelines to take corrective actions. Prof. Ashish Verma of Civil Engineering Department, IISc carried out an extensive study to analyse how drivers' vision influences road safety.
