A guy I know uses a partially deflated soccer ball with a rag wrapped around it. He tied the ball to a rope which he uses to drag through the pipe. He works from manhole to manhole fishing wire through the pipe first in order to lead the rope. I assume if you tied a second rope to the ball...

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...

For the dashed white lines I was just going to go with the MUTCD measurements of 4 inches wide and 2 feet long with 6 foot gaps. What if I changed the lane designation? One lane would be a specified left turn lane and the other would be designated for through traffic and right turns. I would...

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...

Cars tend to park along the lane edge limiting the travel width. It was decided that the middle lane is unnecessary at certain locations and should be removed in order to increase the travel width of the lanes here. I personally don't believe the problem here is the geometric layout of the...

Sorry, here is the post again; this time with less typos: Debaser - I will leave the turning lane at each intersection. No future development will take place in the area due to very old infrastructure and a depressed economic environment. The main purpose of this endeavor is to remove the...

Debaser - I will leave the turning lane at each intersection. No future development will take place in the area very old infrastructure and a depressed economic environment. The main purpose of this endeavor is to remove the center turning lane between where there is not an intersection in...

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...

davidgraff, I know how it is, I got out of school last May and I was lucky to find a job. I started looking during the previous November so all in all I spent about 7 months, joined every job search I could find, and sent out over 200 resumes. Below are some ideas that I tried that might help...

The address is North Railroad Street in Phenix City, Alabama. The problem area is between 13th Avenue and 16th Avenue. The business is at the west end (16th Ave.) of the street. There is an access road in front of the business but tractor trailers cannot use this due the steep grade here. If...

Thanks for all the help. The first time I took a look at the situation I only had time for a quick review and drive-through. This morning I went back and walked the road and noticed a few things I missed before. The road is actually only 18' at the wide end. The rest varies between 13'-15'...

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...

Thats the link I used. I downloaded every version they had but could not get any to run. Each time I would try to install the program I would get an error message and it woud just freeze. The language is in Spanish too so I had to download an Spanish to English translator program just to read...

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.

What is your opinion/advice concerning a retaining wall intended to carry traffic and has a culvert carring water underneath it?

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...
