Maybe we should trust trained engineers to decide this stuff instead of whatever the planners decided was trendy last week.
What an odd post. Do you not realize that trained planners also went to college, likely grad school, and have been certified through the AICP and need to maintain their professional title with annual courses?
Streetmix is an excellent tool to assist with public engagement and also as a first draft to a project because it is so quick/low-cost to use.
And as the name suggests, the target are streets, not highways.
Planners are not engineers, so there needs to be a divide between their duties.
And no one is trying to pretend that Streetmix produces engineering documents.
Here is what they say about themselves:
"Design, remix, and share your street. Add bike paths, widen sidewalks or traffic lanes, learn how all of this can impact your community."
It's a planning tool. And it does a good job at it. Much better than spending hours in AutoCAD and then Adobe Illustrator to produce the same result.
Let me rephrase the previous post to see if you agree with it:
"Maybe we should trust trained planners to model this stuff instead of whatever the engineers decided was trendy in 1948."
Personally, I find this statement rude, condescending, and unproductive to the topic at hand.
