The term “Butterfly effect” was coined by Edward Lorenz based on the theory that a single flap of a butterfly’s wings in one part of world could set off a tornado in another part of world. The concept – which posits that small variations at the outset can have profound implications down the road - can be applied to transportation engineering, especially in the context of non-motorized transportation infrastructure. To understand why this is so, let’s look at the case study of Bangalore City.

In Bangalore, pedestrians and cyclists are in the minority, constituting only 8% and 2% respectively of total trips. However their small numbers obscure an important fact - they play an important role when it comes to accessing public transportation.

As part of its efforts to create a more sustainable transportation system, the government plans to unleash a whole host of public transportation improvements – a metro, monorail, bus rapid transit, general bus improvements and a commuter rail. The total Traffic and transportation budget for next 16 years is nearly $12 billion with 79% of the total investment allocated to mass transportation.

By contrast, the total investment planned for pedestrians over the next 16 years is a scant $72 million, or just 0.6% of total investment. The government plans to improve around 350 km of one-way footpaths and construct 68 grade separated crossings with the money. The proposed cross-sections of the arterial and collector roads show cycle lanes but it remains to be seen if any exclusive lanes for the cyclists would ever be built in Bangalore.

In ancient Indian and Chinese texts, writers noted that the ultimate form of torture involved subjecting captives to loud and horrible noises. It’s an interesting paradox that we now live in the modern world as free citizens, and all we need to do is stroll down the street to be exposed to noise loud enough to become physically ill, elevating our blood pressure to unhealthy levels, interfering with our sleeping patterns, and causing a whole host of stress related diseases.

On the majority of roads in cities like Bangalore, Mumbai, and Delhi, noise pollution can measure nearly 80-90 decibels during peak hours. That’s roughly the equivalent of standing just 15 feet from a passing freight train! Noise levels above 80 decibels are detrimental to healthy hearing and the Australian EPA suggests that prolonged exposure to noise at or above this level can cause deafness. It’s such a serious problem that researchers in the EU found that the social cost of noise pollution for that region is 0.4% of total GDP. In Indian city’s it must be a lot worse. (For normal tension free conversation one requires a background noise level less than 55 decibels.) Read the rest of this entry »

Krishnappa is a security guard for a multinational software firm in Bangalore who, for the past thirty years, has walked and cycled to work. For Krishnappa, the trip, which often took around 15 to 30 minutes, was one of life’s small pleasures as he made his way along Bangalore’s tree-shaded streets, often meeting friends and acquaintances, discussing politics and family matters, before continuing on his way. However, in recent years he has been unable to walk or cycle to work. And it’s not because of age or injury.

When asked about his transport woes, he blames the government. The increase in land prices, lack of cycle tracks, footpaths, poor public transportation, and the risk of being struck by a motorized vehicle have forced him to drive to work. He now spends nearly 30% of his salary on his monthly commute.

Krishnappa is not alone. Rapidly growing Bangalore city has generated a new human species aptly named “Transport Challenged People.” The common trait of these people is that they are forced to become captive to a mode of transport just because they don’t have an accessible alternative. Their other characteristic is that they pay a price for traveling that they do not consider fair or just, but because they have no other option, they continue to pay it.

Bangalore has seen a spiral of economic activity and urban growth, with the developed area of the city increasing from roughly 175 square kilometers in 1971 to more than 560 in 2006. The government, in order to decongest the city center, restricted the Floor- Space-Index (FSI) – that’s a technical term for building density - in the core and liberated the FSI along the outer peripheries. The restriction in FSI in the city core caused land value here to skyrocket, driving out the lower class to the more affordable peripheries. (There’s a photo essay after the jump)
