In a carefully researched and well-documented paper “Congestion to Demotorisation - A Paradigm Shift for Bangalore” (PDF with full text), Sudhir Gota and Prashant Mutalik describe the current issues with congestion in Bangalore, India and propose a solution: partial-demotorisation, replacing many car trips with public transit and non-motorised vehicles such as bicycles.
When asked how he got interested in sustainability, Sudhir says, “I am a Post Graduate in Transportation Engineering from India. I am working as a Project Engineer in Secon Pvt Ltd a top Civil Engineering Firm based in Bangalore. I basically work in Highway Geometric Design & Traffic Engineering aspects of Roads. Well, my interest in Sustainable Transportation started when I started visualizing the after effects of some of the supply intensive actions of the road development. I have seen newly opened flyovers getting congested in 2-3 months, footpaths being removed for increasing the road widths etc. Constantly encouraged by the family, colleagues and the company management, I started my research on sustainable Transportation. Now this interest has grown into a passion where I constantly think about improving the liveability of city by providing sustainable transportation.”
When asked about next steps, Sudhir says, “Authorities in Bangalore have to improve footpaths, provide cycle tracks and improve public transportation. By implementing these three simple actions we can have sustainable Bangalore.”
From the paper, this is a a graph showing the number of vehicles on the road in different scenarios: the current congestion, the ideal mode split, and a sustainable scenario. IPT stands for Intermediate Personal Transport: a three-wheeled car.

The paper’s conclusion:
“In this paper, the author has highlighted the rapid motorisation phenomenon of Bangalore city. Such a high motorisation levels have transformed Bangalore from being a “Garden City” to a “Vehicle City”. The future looks bleak with many companies rolling out small-cheap cars under the banner of “People’s Car” which may further increase the vehicle ownership. The government for long has neglected the public transportation which induced such an concept of personal mobility instead of people mobility.
“The congestion terminology has long being exploited by the planners to roll out massive investment projects such as road-widening, new roads, elevated flyovers-corridors. Such an attitude has resulted in Bangalore being itself in vicious cycle of congestion-vehicles-supply-landuse.
“In this paper, the author has proposed partial demotorisation of Bangalore by highlighting the issue of congestion costs. Using various studies, the authors have computed the congestion costs for Bangalore city which is nearly 208 million Rupees/day. Such a massive burden due to concept of personal mobility needs to be reviewed by the government. The inter city movement and freight movements were not considered when computing the congestion costs due to scarcity of reliable data. This may form the basis for future study.
“Further the individual trip making characteristics needs to be modified by the government in order to shift the mode split towards sustainable environment. The authors have computed the number of vehicles that needs to be prevented on roads to have such an sustainable transportation.
“An important question of “How to Demotorise?” has not been researched upon in this paper as it is a research topic in itself. Research on this topic forms the future scope of research. Additionally research needs to be done on environmental-accidents aspects of such motorisation which has not been included in the present study. Traffic police has urged the government to implement immediately the odd-even vehicle registration concept in Central Business District. This only shows the urgency/gravity of the problem. Any steps taken without improving the public transportation would be myopic in nature.”
