I hope that car occupants are OK.
The driver thought he is sher but "sher tu ulta pay gaya sherpao bridge par".
I know many members have read it. But for the knowledge who havnt. I posted my comments on another thread.. copying it again, simple 8th class physics here under chapter of circular motion..
A simple definition is the force that pulls an object out from the center of a curve.Centrifugal force comes into play when you're rounding a curve. It tends to pull your vehicle out away from the inside edge, regardless of which direction you're traveling.
If a car on the "inside" lane of a curve tries to navigate with too much speed, centrifugal force will pull it away from the center and, potentially, into the path of oncoming traffic. Or, if a car is traveling with too much speed from the other direction--in the "outside" lane of a curve--centrifugal force will pull it out to the right and off the roadway.
As far as designing of the bridge. Its not a one day job. traffic study, feasibility as well as current situation on the location plays an important role. It takes years for the final thing to come on sheets of drawings. Road signs and speed limits signs are MUST at such areas.
If you have un- planned cities we will come across such designs. There is a bigger responsibility on the part of driver. follow the signs. Now question is are there any CLEAR LIT FLASHING/reflective road signs or NOT? Road signs is complete engineering. The sign size, design, font, color, background at what location and at what distance it should be posted. sometime People don't follow signs even on plain straight road.
Bridge location and design also depends a lot on the current existing situation on ground as well. Public properties, other infrastructure as well as public utilities is the basis issue as well. I don't want to go in details. But its my subject and questions are welcomed.
Ok lets watch this video. specially after 2 minutes into play onward. Do you see a curve. People speed here and you can see the the crash overmarks on the road edge barriers. People leaving city and taking this bridge after stuck in traffic for hours speed on brdige and don't follow signs and bang onto the edge. SPEED LIMIT IS 30MPH. as per law. on curve its posted 15.
