Rick F Guyon - Road Safety Features - Richard F Guyon

Road safety features are installed to protect public life and property and to reduce traffic-related lawsuits against highway and transportation departments. The most common actions include the installation of illumination, guardrails, and impact attenuators, as well as the relocation of dangerous facilities.
Guardrails are used on roadways where there is a severe slope or vertical dropoff to the side of the road, ditches, permanent bodies of water, embankments, and roadside obstacles. Guardrails with turned-down ends are now prohibited in new installations and should be upgraded. Such guardrails, rather than protecting motorists from a fixed impact or spearing, often cause vaulting and subsequent rollover.

Rick F Guyon - Speed Degredation on Uphill Grades - Richard F Guyon

Rick F Guyon - Most modern passenger cars traveling on highways are capable of negotiation uphill grades of 4 to 5% without speed decreases blow their initial level-highway sppeds. (Older cars with high mass-to-power ratios and some smaller-sized "economy" vehicles may experience speed decreases.)

Heavy trucks experience greater speed degradation than passenger cars. The primary variables affecting actual speed decreases are the grade steepness, the grade length,  and the truck's mass-to-power ration. Mass to power ratios are commonly stated in pounds per horsepower and kilograms per kilowatt.

Rick F Guyon - Richard F Guyon - Light Pollution

It's sad that for many people around the world they will not be able to look at the night sky and see the stars like our ancestors did. It wasn't just one or two dots. They could see the bands of our galaxy. They could see other galaxies and other planets. How come we don't have that same view?
Light Pollution - For those of you that live in the city...the lights coming from the streetlights, homes, apartments you name it creates a halo almost that doesn't allow us to see the stars visibly. See in the city it never really is dark. When you look at a city hub from the outskirts of town you can see that glow in the sky..well the glow also prevents you from seeing the beauty of space and what we have so much yet to learn.
