Exploring the relationship between speed, safety, and geometry of roadways.

If you’re thinking about the roadway itself at all while you’re driving, it’s probably because it was poorly designed. There are so many factors that go into highway safety, many of which are more philosophical or psychological than pure physics and engineering. But to a certain extent, highway design is an art form. -Patreon: https://ift.tt/27tcvqH -Website: https://ift.tt/1Th3U0B Writing/Editing/Production: Grady Hillhouse Editing and Direction Help: Wesley Crump This video is sponsored by Ting.

Of all the ubiquitous things in our environment, roads are probably one of the least noticed. Our roads see tremendous volumes of traffic and withstand considerable variations in weather and climate, and they do it on a pretty tight budget. That’s really only possible because of all the scientists, engineers, contractors, and public works crews keeping up with this simple but incredible material called asphalt. -Patreon: https://ift.tt/27tcvqH -Website: https://ift.tt/1Th3U0B Writing/Editing/Production: Grady Hillhouse Editing and Direction Help: Wesley Crump This video is sponsored by HelloFresh.

How Does Permeable Pavement Work?

One of the most significant changes to the landscape that comes with urbanization is impervious cover. That's anything that prevents rain from soaking into the subsurface: buildings, sidewalks, driveways, and the biggest culprits - streets and parking lots. Impervious cover is a big issue. When you pave paradise to put up a parking lot, you cause a pretty significant disruption to some really important natural processes in a watershed. But, not all cover has to be impervious. -Patreon: https://ift.tt/27tcvqH -Website: https://ift.tt/1Th3U0B Writing/Editing/Production: Grady Hillhouse Editing and Direction Help: Wesley Crump This video is sponsored by HelloFresh.
