Point is : How does one assess what the state on the ground would be once tunneling is completed (Assuming tunneling requirements are met).

This article mentions a few technical details.

The area has loose soil, so is more at risk. Also they seem to have monitoring systems (at least theoretically) in place.
What irks me is that officials simply say "Such things happen" and nobody bats an eyelid.

Simpson's accent: "Whatever!" Indeed it is irking. Ultimately, the metro just might be a blessing for Chennai, but, year after year after year it continues to be a curse.

I wonder how much damage the Honda suffered. I wonder who will pay for it, and how promptly.

A Maruti Baleno RS accident in Kerala:

found an interesting article regarding road safety from stray cattle.

Cows and Cars: Ahmedabad engineers develop alert system to save their collision on Indian roads

The stray cattle has been an issue for both animals and drivers.

To save them from colliding with cars, Indian engineers have developed a real-time automatic obstacle detection and alert system.

The system uses a dashboard camera and an algorithm that can determine whether an object near the vehicle is an on-road cow and whether or not its movements represent a risk to the vehicle.

Thanks.

To save them from colliding with cars

Isn't the problem the other way around? And if a driver can't avoid a cow, what chance does a child have? And, haven't Scandinavians done this with mice, or mooses or something, a few years back?

(given the month, I wondered if that article would be dated 1st. But it wasn't.)

[Ry_der]

Even I am quite skeptical about the idea. How a camera with motion detection algo will help when a stray cow suddenly appears out of the divider bushes on a higway at tripple digit speeds?

Lets see how long Chennai takes to repair the road

Japan fixed it in 48 hours. The race is ON!

Based on the video clips, the Chennai spot appears to have become a tourist attraction.

With regards to bikers riding on extreme left side of the road. That is ok if the biker is going significantly slower than the traffic. But for this biker going at decent speeds, he was at the right place.
I attended biking schools in the UK and they have the concept called the 'command position' when riding bike on the road. That means that in single lane roads try and ride in the middle of your side of the road (as long as your speed is decent), to prevent exactly these kind of drivers from trying to unsafely squeeze through when the road is not clear, with oncoming traffic.

Common sense would dictate that , as a biker, one needs to look into mirrors and check over the shoulders to have situational awareness. It also means that if you see a maniac in a car coming too close for comfort, then anticipate the situation and slow down a bit to allow them to overtake.

But in this particular case, there is no doubt that it was the car drivers fault, even if he had honked and flashes lights etc, as somebody else suggested he might have!. There is no excuse for a hit and run. I hope he got his just rewards.

Well let me rephrase : The cardriver was definitely guilty. No doubt about it. The car driver is a cabbie and like every cabbie in india , has virtually non-existant road sense. This person doesn't even have the capability to develop road sense. This person is most likely not educated and probably graduated from 3 wheeler to 4 wheeler. His livelihood depends on him going from point A to Point B asap.

The Bike driver : Educated and possibly from a well to do family. This person has the capability to have road sense. This person's lively hood is not based on driving from point A to Point B. This person could have easily allowed the cab to overtake him and continue with his joy ride. But he choose to engage in either a) ego war b) road rage because of constant honking by cabbie c) choose not exercise road sense

In this aspect , I find the bike driver more guilty. You expect more maturity from an educated person when compared to a rustic cabbie.

You quoted UK law. it changes country to country. For example in US, the law states that if someone is tailing you for a while and unable to overtake, you are expected to pull over and allow that person to overtake.

Road-sense expected in this scenario and in every scenario is that if a vehicle is on your tail, allow it to pass by. The vehicle is on your tail not because it intends to tailgate you, it is because it is not being allowed to overtake you.

Well, In my opinion, it will not be even a competition, even though the cave-in at chennai looks quite small as compared to the one you have posted which has happened in Japan.

It'd be great, if it gets repaired at least in a week. If this happened in Bangalore, it will take minimum two or three weeks. First one week will be only blame games, second week some cats will do some inspection and in the third week, something might happen.. Meaning no disrespect to my city, but I fear this is the reality. For clearing a simple clog in the underground drainage, it took the better part of 10 - 12 days near rammurthynagar

Incident 3 : CBR 250 Vs Calf

I was going to my brother's home after office hours via Chennai - Tambaram by pass. I was a bit reckless on bike then, I was about to over take a bus in the middle lane. I was doing 85 Kmph and accelerating.

I just glanced at the median, there were cattle grazing there. I was like, guys don't cross the road now. Then as if this calf hear my thought, decided to jump right in front of me. I looked for the gap between the calf on my right and the bus on the left, braked hard, ABS kicked. My right handle hit the calf, on the face I believe. After getting hit it returned back to the median.

I have to swerve here, other wise you know what would have happened..

My little finger got swollen and as I was convinced that I got a fracture, I pulled over to a small lab to take X-ray. I felt quite dizzy, drank some water and left that place without taking X-ray. Went to Miot hospital and what happened there was quite funny, I will save rest of what happened there for another post.

Not sure how this system will be helpful in India, as an academic project it is good but practically, I see this system as a stand alone solution offer little value addition. Maybe couple this with AEB (Auto Emergency Braking). Software wise, an additional Control Strategy for animal detection.

I wonder at your description of tail-gating. First time I ever heard that view. No, it is not a good one. And no, nobody has a right to overtake, or to bully someone else out of their way, or to overtake in a way that is just horribly dangerous.

Like I said in my last post on this particular accidenL it is one of the clearest posted here. No doubts. But still people want to make and argue them.

I thought everybody was done and through on this particular accident. Sadly, I was wrong.

Anyway, I'm done now.

Anna Salai traffic goes back to normal 19 hours after cave-in


The road has been restored and open to traffic as per news report in TOI today. Looks like it even took Motorists by surprise

Traffic was restored to normal on Monday on Anna Salai at Thousand Lights, almost 19 hours after a cave-in on Sunday on the arterial road, due to metro rail tunnelling work, left behind a large crater into which an MTC bus and a car had plunged. The traffic police opened on the stretch, opposite Church Park School, in a gradual manner.

Police officers first opened the road to autorickshaws and two-wheelers, around 9.30am, after a 2.1 metre stretch was repaired. They opened the section of road to cars and buses in the afternoon. A senior officer from the police traffic enforcement wing said, “At 2 pm, cars and MTC buses were allowed to use the stretch after the approval of Chennai Metro Rail Ltd (CMRL) officials.“

K Sathish, a motorist, said, “I didn't think the repairs would be completed so soon. I started from home a little early to avoid getting caught in traffic caused by vehicle diversions.“

Police sources said the traffic flow had reduced in the morning hours on Anna Salai toward Saidapet and Guindy as many believed that the road was closed to vehicles.

Wow, that's great. I was expecting at least a couple of days work to complete this. In the cave-in that ocurred last week, they put a ribbed metal plank/sheet to cover it. Wondering what they have done this time.

There are some fresh cracks along that road I hear.

My guess is that the entire length of the metro tunnels has to be heavily reinforced with metal and concrete. If it is like this right now it will be much worse when trains start operating underground.

I did watch the video and what i observed was that this was not a full video. I wouldn't be surprised if there is more to the background.

At 24th second, the car was behind the bike. Till the 36th second, the biker was on the left side of the road giving the cabbie enough space to overtake. However when there is a bus comming from the opposite direction, the biker starts moving to the center of the road .

So basically he invites the cabbie to overtake and then tries to block him by moving towards center of the road on the 43rd second.

Why he did that can be anyone's guess. But that was strange in my opinion. I expect such nonsense from Cabbies , not from educated people like the bike driver.

Well about tail gating, thats what I follow, because that makes sense to me. Well you can say that part of US driving culture rubbed on to me.
In India, I consider everyone on the road except me as grade 1 idiots, hence I take precautionary measures.

Again, your comments are belaying the actual facts. The way the cabbies , autorickaw drivers, bikers(in city), bus drivers , other commercial vehicles drive is nothing short of bullying. Are they right driving that way ? Nope. Can you realistically do something about it ? Nope again

You have to accept the ground realities and adjust.Technically you don't need to . It is unfair, but such is life.

AGAIN : The car driver is guilty of running into the Biker. No questions there.
But it doesn't mean that the biker is completely innocent.
