should speed monitoring radars be installed in india with accidents being on the rise?

yes i think its high time india had some speed monitoring radars which will definately reduce the number of accidents.

The first poster is correct.  The link in "sources" gives a chart showing the RF spectrum allocation for the U.S.  Police Radar is at 9.5-10 GHz.  Satellite TV is at 12 GHz.\n\nThe second link provides information on the politics and economics of frequency allocation.

RUMBLE-STRIPS SAFER\nRumble strips on rural roads can reduce\ninjury accidents on rural roads by up to\n25% according to a recent paper\npublished in Accident Analysis and\nPrevention. In “Crash reduction\nfollowing installation of centreline\nrumble strips on rural two-lane roads”\nPersaud, Retting and Lyon conclude\nthat rumble strips should not be\nreserved for specific areas and should\nbe applied to all reasonably well\ntravelled rural roads. As in New Zealand\nthe majority of injury accidents in the\nUS occur in open road areas. They note\nof all the treatments available to\nprevent head-on sideswipe collisions\nrumblestrips are the cheapest.\nsource: Accident Analysis and\nPrevention 2004

I'm guessing that you are asking because you are looking to purchase.  With that it mind here is some info and I hope it helps!\n\nIn early radar detectors:\nS - Band Radar : operates at 2 - 4 GHz\nX - Band Radar : operates at 10.50-10.55 GHz (Not accurate below 20MPH)\nK - Band Radar : operates at 24.05-24.25 GHz\n\nIn modern radar/ladar detectors:\nKa - Band : operates at 33.4 - 36.0 GHz (has 13 200-MHz channels, can operate in “hop” mode)\nLadar : uses light emitted at 904 nm (typical)\n\nAdvantages of Radar\n*Very flexible - can be used in a number of ways (Stationary mode, Moving mode, Two Directional mode)\n*Beam spread can incorporate many targets\n*Can often select fastest target or best reflection\n*Still very reliable\n\nRadar Disadvantages\n*Time - Radar can take up to 2 seconds to lock on\n*Radar has wide beam spread (50 ft diameter over 200 ft range)\n*Cannot track if deceleration is greater than one mph/second\n*Large targets close to radar can saturate receiver\n*Hand-held modulation can falsify readings\n*More interference sources\n\nLadar Advantages\n*Faster lock-on time (less than 1/3 second)\n*Very narrow beam spread (less than 6 ft over 2000 ft range)\n*Better ability to track decelerating targets\n*Typically mounted, and aimed with optical targeting device\n*Fewer sources of interference\n*Much more difficult to detect\n\nProblems with Ladar\n*Particles (dust, water) in air can limit range\n*Rounded surfaces, the colors black, blue, and violet are poor reflectors\n*Can be difficult to track target\n*Alignment can cause severe error\n*Extreme sunlight can be damaging\n\nConclusions\n*Ladar is, in the correct environment, better suited for speed detection\n*Ladar is not perfect, however\n*There is still room for Radar patrolling\n*Both could be used in concert to achieve maximum detection capabilities

Absolutely. \nThe driver is entrusted with the lives of children and should not do anything to endanger them. A crash at freeway speeds to children in a bus can be fatal.\nEdit.\nNot to mention the danger to other people on the road.

This sytem was in place before GPS it was called Loran it was not as accurate. Really good thinking though Barbie, you are going places. Let me add that a system is in place now to locate cell phones in exactly the way you propose for emergency situations. However I believe in the future cell phones will incorporate conventional gps, as in an eperb and also for the user as location info.

If you are travelling fast I would think the signal would be completely disrupted...:D

I drafted a pretty good LIDAR (laser-radar) speeding defense using these websites:\n\nhttp://www.helpigotaticket.com/proc/...\nhttp://www.tipmra.com/\nhttp://www.ticketassassin.com/\n\nThey give free advice for beating traffic tickets. I must caution you to verify the law contained in these websites. Hope this helps.

Very doubtful.  The JUGGS radar gun that most professional teams, as well as scouts, use are upwards of at least $700.  The problem with clocking a baseball is that you have to be able to "track" the ball and it's path.  You can not simply point the gun at a ball in mid-flight and hope to get a true reading, because an "instant on" type radar would only show the speed as being "0" at that one moment due to the fact that it is simply taking a "picture" of the ball in flight, versus tracking the ball for 60 feet.  A radar gun uses the formula of feet traveled; as F  dividied by Time; T, so F/T=mph, of course you have to change the units of measurement to convert to MPH.  You have to change the feet per second to correspond with miles per hour.  I can post the formula later if you would like.

UMMM NO.  What kind of question is that????  If someone is moving that fast on you, you better be careful.

I think there are enough open roads to allow for it safely. Provided the right roads are assigned the correct MPH, then I see no problem with it.

if it had government plates it probably had a good reason to be going fast, maybe you should stop being a pain in the a$$ because whoever you report it to isnt going to care anyway . . also if the care were going in excess of 100 mph how did you have time to accurately guage the speed, evaluate the occupants, and catch the lisence plate?

Last week on the motorway, a lorry coming the other way crashed through the central reservation and took out 2 cars 100m in front of me.  3 people died.  If it had happened 5 seconds later it would have been me.  I guess it was not my day to die.

Yes Because alot of accidents are casued by people talking on their cellphones

On both counts. Take the number and report them. The police aren't angels to be there all the time. It's up to responsible road users to do a certain amount.\n\nI know one report won't do a lot but a tailgater is likely to do it more than once and one day he'll cause an accident.\n\nI have to say that, though I think this is the proper thing to do, I have never done it (either reporting or tailgating!).\n\nMost tailgaters are just a nuisance - that's what they intend to be - so to respond to their rudeness at all just feeds their aggressiveness. I would certainly note their number if they were obviously putting lives at risk, though.\n\nAs for mobiles ... a friend of mine passed a car that was driving erratically. It was a people carrier with three small kids inside. The mother was driving at 65-70, had a mobile on her shoulder and was checking her makeup in the rear-view mirror!!! I have many times encountered similar (though not quite as multitasking as that). The worst offenders, though, seem to be tradesmen, who live on their mobiles. The kind who plonk their phone on the bar in the pub and get 3 calls in half an hour - none of them about work - which they answer as if there was something wrong with the reception. Grrrr!

It is a good idea, though the GPS should be really inconspicuous. It was used by my team in a war game played in India (Asia). Hope u know where it is!!\nWe won the game so easily, but in real life the PoW are stripped and searched, so using it in military is out of qustion. Only a crazy general would allow it, but I liked your idea.\nGood to have such bright, intelligent questions asked.
