Visibility

Our other concern with this project is visibility of Lane lines and other traffic signals on roads.  We spoke with Scott Nazar, a Penn Dot representative over the phone and he gave us advice on what
to do about the LED lights. He said that it was a good idea but it would cost a good amount of money.
We thought about using mostly Solar-powered lights instead of electricity-powered so that we can save
energy.  This method proves inconclusive due to the lack of testing on the durability of solar-powered lights.

We also thought of mounting the streetlights on the roads instead of on poles for better visibility. We did some research and found that the visibility would actually decrease if lights were implemented on the ground because we didn't take into account oncoming traffic and other obstacles blocking the light coming from the ground.
We decided that these lights mounted should be LED lights as well
so as to save energy and also reduce the cost for maintenance of the lights. Through research we found
that even though the initial cost of LED lights are high, overtime the cost is drastically less than the use of normal lights such as halogens.  This can be seen in the table below [12]:

Also, mounting the LED lights on poles would actually increase the focus of the light being emitted and reduce the amount of light energy being wasted.  [11]  LED lights are special, in that they have the ability to focus the light onto one spot, creating stronger visibility.  To the right is an example of an overhead LED light from Cooper lighting, a company which sells roadway lights.  The group is currently researching more on what exact head should be used to light the roads and we must also compare the heads to other types currently being used.
