I wasn't aware I was watching a small channel until I finished the video and saw the subscriber count, good job on the video! I hope your channel grows ♥
Found the video on the homepage. I think you have a great thumbnail. My guess is that this video would preform better than ur average video. Viewcount at moment of writing comment = 287
@Design Nerd I can see at this moment that the viewing count is slowing down a little. So it's probably showing fewer people this video. I think it is because not enough people are engaging with this video. Try to add like a question to the video next time. When people answer the question, you have more engagement.
Yes, mostly because of speed. Speed is a major factor in selecting superelevation rates and radii of curves, sight distance, and the lengths of crest and sag vertical curves. Roads with higher design speeds require wider travel lanes, steeper curves, wider recovery areas, broader clear zones, steeper curve rounding, longer sight distance, and more gentle hill crests and valleys. All of these design elements have changed to match the increase in speed. Interestingly, the situation in urban road design is the opposite. There, on the contrary, they try to slow down traffic by creating artificial barriers, curving roads, installing speed bumps and so on.
A spiral curve will have an increasing radius in one direction (safer) but a decreasing radius when travelling in the other direction (less safe). How is that determined? I can see how a downhill section would need an increasing radius and the uphill direction could safely use a decreasing radius, due to slower speed and greater vehicle control - are there other cases where a decreasing radius is considered OK?
Curves with a decreasing radius can be considered OK on roads with low speed limits. In this case, drivers can anticipate the decreasing radius and reduce speed accordingly, reducing the risk of losing control of the vehicle. Another example is when a road is designed to accommodate slower vehicles, such as bicycles or pedestrians. Adding warning signs, guardrails, or lowering the speed limit can, in some cases, makes reduced-radius turns safer. However, they're still dangerous, especially if they're poorly marked or not visible. Thank you for the question!
Go look into German highway (Autobahn) construction it is way more complex and also efficient compared to the shitty American highways (speaking from experience).
@@ValentinShevtsov for example they are right now building a roof over the Autobahn in the city of Hamburg to gain some more space for other things but also take the highway out of the view, really interesting project if you ask me. It's called "Autobahn Deckel" (Highway lid)

Very well made video, really enjoyed watching and didn’t even realise it was a small channel
Thank you so much! I appreciate it!

Such comments make me truly happy. Thank you for kind words!
Same great work, keep it up
@@KosiWien Thanks!
I thought I was the only one who thought of road transitions like roller coaster transitions and how flawless some are

You know how to compliment a UA-camr. Thank you! Indeed, I hope that more people will discover this video. If you're here, then I guess it's working!
@Design Nerd No problem. I try to recognize the algorithm so I can use that information with producing videos on my own.
@@lucasvanthul That's a good strategy. Good luck with your videos!

Amazing video 🎉
Thank you!
That was very informative, thank you!
Glad it was helpful!
great video, really cool
Thank you! Glad you liked it!
Wonderful video
Thank you!
I wonder if road design has changed to account for better handling/safer/faster cars and tires
Yes, mostly because of speed. Speed is a major factor in selecting superelevation rates and radii of curves, sight distance, and the lengths of crest and sag vertical curves.

@@ValentinShevtsov super interesting! Thank you for the reply.

Autobahns really are amazing! I’ll look into it. Thanks.

Our tax money is the only way to design any Highway
