On September 24th, Prof. Ashish Verma, Convenor, IISc Sustainable Transportation Lab (IST Lab) released a voluminous 479-page report co-authored with Hemanthini Allirani from IST Lab, recording air quality index and several other indicators of Quality of Life (QoL) due to 'pedestrianising urban streets' - essentially closing roads to traffic. This is a part of the Innovating for Clean Air (IfCA) programme, a joint initiative between India and UK to pilot air quality improvement initiatives in Bengaluru. Being the first such initiative in Karnataka, the initiative is named ‘Church Street First', based on the location of the study. Church Street was…

October saw heavy downpour in Bengaluru, causing flooding and traffic breakdowns in many parts of the city. The city usually gets much of its rainfall in the evenings and nights, which also makes it more vulnerable to flooding and traffic jams during peak traffic hours. Floodings have been one of the most common, inevitable outcomes of climate change. The constant feeding of emissions into the atmosphere leads to extreme precipitation, which then results in floodings. Urban flooding affects transport in different ways, such as increase in travel times, change in route, congestion due to low speeds, etc. There is an…

In considering sustainable urban mobility as a solution to urban transport, one parameter that is constant is the Volume to Capacity ratio or V/C ratio. Why is this? Traditionally,  transportation engineering in urban areas has taken a bottom-up approach. In other words, it follows an infrastructure supply-based approach, and critical to this is the V/C ratio. This ratio is calculated using Passenger Car Unit (PCU) for every road in the given urban area to identify hotspots of congestion, so as to figure out infrastructure-based interventions like road widening, flyovers/underpasses, elevated road corridors, etc.  But over time, such interventions have proven to…

[This article is part of the Bengaluru Moving series, in which citizens share their vision for BMTC post COVID. This series is pubished in collaboration with Radio Active's #BengaluruMoving campaign. In this first part of the series, a transport expert shares his ideas.] Before we look into ‘post-COVID’ Bengaluru, we need to look back at how our transport system was in pre-COVID Bengaluru. We were facing extreme growth in: Vehicular traffic (both in terms of number of vehicles and vehicle kilometers travelled) and congestion on city roadsTraffic accidents and fatalities, especially of vulnerable road users High levels of exhaust emissions including…

The BMRCL and DULT have come up with a draft Comprehensive Mobility Plan (CMP) 2019 to achieve sustainability, and thereby improve liveability in Bengaluru. The CMP develops 10 strategies such as augmenting capacity of public transport, promoting the use of electric vehicles, and so on. It further develops three sustainable transport ‘options’ or scenarios, each by grouping a certain set of the strategies. And then analyses the impact of each option on modal share and emissions in the city.  Eventually the CMP identifies several projects, which would be implemented in three phases. CMP has been technically reviewed by Dr Ashish…

I was pretty excited and went with a lot of hope to attend a 'Namma Karnataka' development conclave at Vidhana Soudha on February 17, jointly organised by a media house and Government of Karnataka. The event, however, turned out to be a major marketing and propaganda exercise of government’s infamous Elevated Road Corridor Project. Large flex banners highlighting the project had been put up at the venue, and the panel discussion on Bengaluru’s transport issues hardly had any discussion, and there was no question and answer session. Since I and many other invitees did not get an opportunity to voice…
