For many in India, cycling is a foreign idea, something that weird or poor people do, or its a toy that children play with. It has been culturally diminished. A pariah. The problem is powerful people think that, hence no skin in the game for those that make policies.

(July 2017) - We study the impact of an innovative program in the Indian state of Bihar that aimed to reduce the gender gap in secondary school enrollment by providing girls who continued to second...

I ♥️ this. Similar to some of the streets in Delhi. I tell my students that traffic like this (ofc with better infra for ped and cyc) is how we can imagine a low-carbon future. Peds, cyclists, public transport and "low-powered" motor 2-wheelers (e.g., e-bikes). Hardly a car!

In general, be careful when using vehicle ownership numbers for India from internet sources. They are often based on bad primary sources, or there is no clarity of the geography (city, district, state) they are trying to report.

I mean the AI/ML applications to give any insights into solving road safety problem in India remains quite limited. This desperation to use these methods also comes because of an overwhelming number of people who work on transport have engineering background.

What we really need is greater collaboration across disciplines. Transport researchers should reach out to colleagues in social sciences and development economics. At IITs, we do have that privilege with humanities departments, and it is true for many other universities in India.

Cyclists in Delhi putting retroflective markers to a better use. "Raat ko badhiya chamakta hai" said the security guard. "Sadak pe mila tha" he said with a grin😀

which is then coded into a structured database. Finding the geographic location is a nightmare. So, before one could make nice maps of road crashes with attributes that you can trust, hours and hours of RA work has to go in.

Again, internationally, it doesn't matter what your working status is, whether you are unemployed or working, your likelihood to go out of home does not change. Of course what may change is how far you go, etc.

But I don't see this problem of bad research going away, soon. Because the solution is structural changes. Many road safety researchers are housed in engineering departments, and those committees judge their research on "technical" aspects of research.

In a study by @iitdelhi , cyclists were found to be 40 times more likely to die in a road accident than passengers in a car. For a large section of the population to take up cycling voluntarily, this safety gap must be bridged. A thread:

Another alternative forced on cyclists when a mid-block crossing was closed off on Mathura Road-- a foot over bridge. As if that wasn't enough there are two layers of bollards to navigate through.
