I can't properly comment on Autocad as the last time I worked with it was more than 10 yrs ago, but if Autocad seems so bad, why do companies stick with it?

There is too much auxiliary software bonded to Autocad. Also dwg format is practically de-facto standard for drawings, and is often demanded by customers and authorities (depends on the country though). You could ask the same: why companies stick with Windows and MS Office software if they have free alternatives?

I am bridge design engineer, and I use AutoCad 2009 (full version) plus additional Polish program BestCad which works in AutoCad enviroment and is specially written to help design bridges and viaducts. A lot of road design engineers in Poland use Microstation but some of them use also Civil 3D.

Mathematical formula for perfect parallel parking

Just use this formula to help you make a perfect parallel park.





Find the actual formula document here:

Scientists create formula for perfect parking
Telegraph, By Murray Wardrop, Published: 6:55AM GMT 11 Dec 2009
http://www.telegraph.co.uk/motoring/...t-parking.html

For those who dread trying to squeeze their car into a tight space, help is at hand – scientists have created a mathematical formula to help motorists park perfectly.


UK Boffins have come up with the formula for working out how to fit your car into a tight parking space. Photo: SOLENT
The equation is the result of a collaboration between Vauxhall Motors and maths professor Simon Blackburn.

Prof Blackburn, from the University of London's Royal Holloway College, came up with the formula to make even the trickiest reverse parallel parking situations a breeze.

However, to the average motorist, its array of square roots, brackets and symbols is likely to lead to more confusion than the driving task at hand.
The formula was released after a Vauxhall survey showed 57 per cent lacked confidence in their parking ability and 32 per cent would rather drive further from their destination or to a more expensive car park, purely to avoid manoeuvring into a small space.

The least confident parkers were those from Norwich, while the most confident were the Welsh.

Professor Blackburn said: "Parking the car is something that most of us do on a daily basis – and we all get a little frustrated with it sometimes.
"This was the perfect opportunity to show how we can apply mathematics to understanding something that we all share.

"The formula and our advice can help people understand what good parallel parking involves.
"If you understand the angles and the dimensions of your own car then you can work out how to park in a nice, confident way.

"Everyone has had the experience of ignoring a space because you're not sure if you can fit in or not. This formula solves that problem."
The formula begins by using the radius of a car's turning circle and the distance between the vehicle's front and back wheels.

Then, using the length of the car's nose and the width of an adjacent car the formula can tell exactly how big a space needs to be for your car to fit.

By applying this to basic parking guidelines, you can work out exactly when to turn the steering wheel to slide in perfectly.
Spaces will be at a premium this year as 35 million shoppers flock to towns and cities to snap up last minute bargains.

However, the survey found that 15 per cent of Britons claim parking their car to go shopping is the biggest challenge they face at Christmas.
Simon Ewart, from Vauxhall Motors, said: "There's no escaping the fact that parking can be challenging for the best of drivers."

British scientist crafts mathematical formula for perfect parallel parking
BY Jacob E. Osterhout , DAILY NEWS STAFF WRITER , Tuesday, December 15th 2009, 3:20 PM
http://www.nydailynews.com/lifestyle...l_parking.html

You've got to be handy with numbers and measurements - and have some extra time on your hands - but this mathematical formula is the key to the perfect parking job

It's the skill that every New Yorker with a car knows.
A scientist in London has created a formula for parallel parking, according to the Daily Telegraph.

To the average driver, the equation, which involves four variables and a multitude of square root signs and brackets, won't make much sense, but to professor Simon Blackburn at the University of London's Royal Holloway College, it's the solution to even the trickiest reverse parking job.
Professor Blackburn devised the formula after a survey by Vauxhall Motors determined that 57 percent of of British drivers lacked confidence in their parking skills.


The equation starts off using the radius of a car's turning circle and the distance between the vehicle's front and back wheels. It then takes into account the length of the car's nose and the width of an adjacent car.

Plug in the appropriate numbers and the equation will determine exactly when to turn the steering wheel to slide into the parking space perfectly.
Next up for New York drivers: a formula to determine the exact right moment to flick tailgaters the bird.

That's really cool... They should instal infrared sensors to measure availabe parking space and sound a beep to advise you if space is not enough to try parking.

The formula has one flaw, it doesn't take into account the margin of error required for women drivers

Asking out of curiosity: How is the behaviour of "drving right" on the highway/motorway/autobahn???

Hi!

Just aksing because i am curious. Do people follow the rule of driving on the right side as often as possible and only dive left/middle lane to overtake??

Here in Germany in my opnion it ranges from 2 to 6 from a scala from 1 worst to 6 best.

But most time it is 3 to 4. in my opnion.

I dont understand why people drove in the middelane altought the right lange is free for kilometers!!!!

that cracks me up!!

Drive on the right when it's possible. Why is that so hard to understand????

It's illegale to overtake sombeday on the right and dangerous (altough i have honest to admit, i have done this some times) but only because the middlane and left lane was blocked with low speed driving cars!!!



The next thing is i would like to know is, i have learned in german driving school that you turn on the turn lights when you reach the 300 meters barrierr, when you leave the Autobahn. I hardly see this. Mostly people turn on the signals when they reached the 100 metert barrier or it's common to see they tunr on the signals one short time when they drive to the exit!!!

Is this the same in your country?

Both the middel/right lane thing and the turn on the signals when you reached the 300 meters barriert????????????????????

thank you for replies

p.s. sorry for my english

in Croatia we had a plenty of left line hoggers. but since you can read often at forums and internet about it, it has drasticly fallen down. so now is actually situation really ok about that. of course, you can allways find drivers who think they are gods on motorway so they drive in left lane (and cars twhich they drive are Mercedes, Audi, BMW, or some expensive other like Touareg or some other large luxury SUV). number of them has also decreased since we have Cobras.

Most motorways here are four-laned. Because of the high amount of traffic, everyone abides by the "hold right" rule. Near Copenhagen, we have quite a few 6/8/10-laned motorways, and here you may experience people not wanting to hold right. Everyone hates lane-hoggers, so if someone is staying in the middle lane, even though lane 1 is empty, people will usually signal the lane-hogger to pull in. After a few of these signals, the lane-hogger will usually get embarrassed and pull in.

Could it be the heavy traffic that makes it difficult for cars on the left lane to move over?

yes, but thats not the point. the point is, why is the left lane is filled with cars, altough the middle lane is free (in an extrem case) thank god, it happend not often.

normally the cars pull on the right when you come closer with you car. its a thing wihich is understand. i do the same.

and as far as possible i ride on the right lane.

flashing light is strictly forbidden.
