I have a street where traffic is high at 7:00 AM and again at 5:00 PM. The residents complain they cannot pull out of their driveways because too many cars are traveling the road. A traffic signal was requested so I conducted the traffic study and reviewed the 8 warrants. None were met. What...
Hello,
Does anyone know of a traffic study done on the basis of justifying a flashing intersection signal (Major Lane flashing yellow, Minor thorough fare flashing red) instead of using a regular red-yellow-green signal? Everywhere I look directs me to MUTCD which leaves it up to either...
Good Morning,
I have attached a picture of an intersection with a proposed line extension for turning.
I know you can use a white line extension like this if you have a dedicated left turn lane. Can you also use a white line extension with a combined-use lane like in the picture? If so, what...
Say, theoretically, that I had a lot of big chunks of concrete that I wanted to turn into a lot of little chunks. I know pounding on them with a sledge hammer would accomplish this, but is there anyway to 'tenderize' these chunks before pounding? Any possible chemical application or process...
Hello,
I have been given the task to address a 2 lane road with a continuous turning lane in the center of the road. The turning lane is a 2 way left turn lane. I have been told to remove the center turn lane in all areas where it is not completely necessary. I am defining necessary to mean...
I have a road that was a one-way but will now be changed to incorporate 2 way traffic. The road is very very old and has been used by the public as a two way road forever. In order to avoid lawsuits we are changing the signs to specify that the road will now be a legal 2 way road.
The road...
Hello,
I am reviewing some old work to get a handle on the rational and modified rational method for making hydrographs. The designer first used the rational method using the time of concentration and an IDF curve to find the rain fall intensity of a 10 yr storm to make a hydrograph.
The...
Has anyone ever used hidrosig? It looks like an extremely useful program. I am having trouble downloading and installing it and would really appreciate any help or advice. Thank you.
Hello,
I am looking for some freeware to do a few things:
1. Take a scanned image of a proposed grading plan and turn it into a 3D model.
2. Run a quick hydroanalysis to see where the water goes when it rains on the proposed site layout. This part could be in 3D or 2D.
I am new at this and...
