Well, I just went to the site and by default it goes to an error page does not give me much confidence in the site. Additionally, if you were to use any of the calculations from the site, you'd better be able to do the calculations yourself if you were stamping the work. Just checking my State's professional licensing board, the owner of the site is not a PE in my State.
Your comment holds true for any software; after all GI=GO. Really wanting to see if anyone has used the programs and what they think of them. They have a trial period of 7 days but I wanted to get some feedback on the site prior to trying it out. I've got a ton of spreadsheets that I've created but I'm always looking for additional programs/spreadsheets that will make my life easier.
Well aside from the Error page on Page 1, I peeked at the stopping sight distance problem and it say an perception reaction time of 90 secs .... 2.5 secs is the norm.
