Blue lights below stoplights confuse drivers

Čtvrtek, Září 1st, 2011

Red, yellow, green – and blue? Blue lights are popping up on traffic lights all over Southwest Florida. Many residents have noticed the blue lights, but don’t know their purpose.

Many drivers have noticed the LED diving flashlight attached to stoplights, but don’t know their purpose.

“We noticed when the white lights turned blue and we guess maybe it was for color blindness,” said Lois Smith of Punta Gorda.

“Now that they are activated and on, we still don’t understand them,” said Dick Smith, Punta Gorda resident.

At the beginning of august blue led lights replaced white lights at 19 intersections - at a cost of close to $5,700.

Many drivers assumed one thing, Big Brother was watching.

“At first I thought it was a camera to take a photo of you if you run the red light,” said Penny Deutsch, Charlotte County resident.

The blue lights on traffic signals are not cameras. They are called confirmation lights. Law enforcement officers use the lights to determine which direction has a red light – to catch red light runners.

“I think it’s a good thing they should have them. People run red lights and I think it’s totally wrong,” said Ruby Ryan.

Ryan says the lights haven’t changed her driving habits.

“As long as you keep to the speed it’s okay,” said Ryan.

The blue lights are expected to last four years longer than the white bulbs. Officers say they are easier to see at night.

That means it will be easier to catch red light runners. The fine for running a red light is $259.

How the Lusitantia Artifacts were Raised By Diver Eoin McGarry

Úterý, Srpen 30th, 2011

Earlier in the month Eoin McGarry led the technical dive team on the expedition that was carried out by National Geographic, this was for a two hour documentary special which will be aired in May of next year in time for the anniversary of the sinking of Lusitania. Due to contractual agreements McGarry cannot discuss the details of that expedition but the recovery of artifacts was executed by him and and a specialised dive
team, and the details of that the Waterfor diver can reveal exclusively here to readers.

The recovery of artifacts took place on the 22nd of this month as a continuation of Gregg Bemis’s five year license. As recovery of artifacts was not on the Nat Geo agenda, their primary objectives were for a forensic examination of the wreck.

Subsequently, it was decided by Gregg Bemis and myself to return to the wreck and recover some significant items from the wreck while his licence was still active.

Agreement from the Irish Underwater Archaeological Unit and the National Museum of Ireland was necessary for this recovery to proceed as the surrounding site and wreck of the RMS Lusitania is a designated National Monument, and while carrying out the recovery we were monitored by the Irish Naval Service.

Many hours of research involving global positioning satellite information, multibeam data and side scan sonar images of the site were carried out to determine the exact location from which to recover the objects.

This is very important due to the physical size of the wreck site, as if you land in the wrong area of the wreck the dive could or would be wasted. Once determined, the remainder of the proposed expedition had to be put in place, a dive vessel suitable in sized and also had to be able to cater for divers, a specially designed lifting vessel that would be able to recover the heavy phosphor bronze bridge telemotor, the dive team, all necessary paperwork and most importantly… the weather.

Bicycles versus Buicks

Pátek, Srpen 12th, 2011

ast week the staff of Dwight D. Eisenhower Army Medical Center mourned the loss of another doctor. This doctor was struck from behind and killed while riding his bicycle. He was riding legally and was wearing the correct personal protective equipment, but it wasn’t enough to save him from a vehicle that was bigger than him.

No bicyclist will ever come out of a vehicle-bicycle collision unscathed. The degree to which the resultant injuries are mitigated will be a factor of environmental, physical, and psychological conditions. Let us look at a few of these.

Environmental: What type of street is it? Residential neighborhood, city street, country road, or divided road, each has dangers that must be anticipated. For example, in residential areas, bicyclists encounter dogs, kids, trashcans and inattentive people backing out or pulling into driveways. City street riders share the road with commuters, bus drivers, distracted drivers, and pedestrians while dodging potholes and drain grates.

Out in the country, a bicyclist may ride on relatively narrow streets, but with traffic traveling at 55 miles per hour or more. A car or semi travels at 55 miles per hour will be upon you and your bike traveling at 15 in a matter of seconds. The vehicle’s driver has to see you and then decide what to do. Even if they are paying attention to driving and have no distractions, it still takes a second or two to decide.

At this speed, the vehicle is travelling almost 81feet per second. This means he will have travelled over 200 feet by the time his brain processes the information and sends the impulses to his body to react. Add to this that most cars take over 200 feet to stop from 55 miles per hour, and the driver will need to see you when he is at least 400 feet away just to be able to respond safely to your presence.

If a curve in the road, hills, the sun, or your dark clothing in any way causes the vehicle driver to not see you from 400 feet away, he will probably have to swerve to miss you, or worse.
