sustainable city transport solutions

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…

On August 24, five months after Cubbon Park was made traffic-free, the Horticulture Department said that traffic would be allowed here again. This was despite BBMP passing the traffic-free Cubbon Park proposal on June 30 and the impassioned appeals of citizen groups like Heritage Beku. For years, activists have been striving for a pedestrian-friendly Bengaluru but evidence suggests there is a long way to go. With its ill-equipped infrastructure for pedestrians, Bengaluru has the third-highest number of pedestrian fatalities among the top eight Indian metros. Pedestrian injuries and fatalities also account for the majority of road accidents in the city.…

[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…

Elevated road on Hosur road. Pic. source : skyscrapercity.com What's the problem? Work commute is taking a hit with traffic congestion on the roads increasing. Since the problem is on the road, the solution has been to increase it and remove perceived obstructions like signals, pedestrians etc from the line of sight of the car to increase speed. One can draw an analogy to an obese person taking on too much comfort food because it feels good and now he/she needs bigger pants. He/she fails to notice that this is potentially fatal in the long run with illness and diseases…
