These some questions that Mr. Josh Donat answered about this project.
1) Are there any standards (ANSI, etc.) that apply so I can read more about this?
Refer to the Texas Manual on Uniform Traffic Control Devices for more information. You may also visit theFederal Highway Administrations Web site for information.

2) Are there any study to determine the location of radar speed signs and what are kinds could use in this location ( changeable massage, permanent signs, trailer signs, or portable signs) or do you use engineer's experience, community demanded, or previous data from collisions and traffic jam?
Yes, there have been previous studies

3) What are the positive aspects of this study?
Increased capacity and improved safety.

4) What are the drawbacks of this study?
None.

5) Are there any numerical data on the result of the study (less accidents, more speeding tickets, etc?
For any data, youll need to file an open records request. By law, you will receive an answer within 10 days. You may need to pay a nominal fee for materials, if needed.

6) What did the data show relative to this study?
Again, youll need to file an open records request.

Signs Information
1) What caused you to think that providing variable speed limits would be a good idea?
This has been successful in other states.

2) Do other states or cities use this approach?
Yes.

3) Can you tell me where I can read more about their programs?
This should be readily available at your university's library on any available research catalog databases that you can search. You might also find some information online at www.fhwa.dot.gov.

4)Was there any visual problems with the color of the LEDs?
No.

5) Was there any issue with the size of the signs and letters (what was the signs)?
Please clarify the question "(what was the signs)?" All letters on the signs met criteria outlined in the Texas Manual for Uniform Traffic Control Devices.

6) Are they going to implement the changes or leave the conventional signs?
Please clarify the question.

7) Do you think if you add any sanctions system, maybe support this device to speed control?
Please re-phrase the question; this question cannot be understood.

8) How much did this cost for the signs (installation, purchase, upkeep, were any stolen or other costs, etc.)?
This information is available via Open Records Request (see above). You can also search

9) Is the cost of radar speed signs reasonable in compared the cost of damages of Humans, environment, and equipment?
Please rephrase the question; it sounds like youre asking if we think the cost of the VSL equipment outweighs the cost of a human life.

Your Data & Recommendations
1) Who did you interview on whether this was working or not?
This is available through an open records request.

2) Can you talk to them for more information?
Once a formative premise of your study, along with a comprehensive and coherent list of questions, is available we can seek appropriate answers.

3) What was the final conclusion?
The final report is still under review; again, this would be available via open records request.

4) Is there anyone else I should interview for information?
Youre welcome to contact representatives of other states as well as representatives of the Federal Highway Administration.

5) Are there any significant information that interested of signs for speed control?
Please rephrase the question; this question is not coherent.

These the questinos that my professor give me to ask Mr. Josh
1) What caused you to think that providing variable speed limits would be a good idea?
2) Do other states or cities use this approach?
3) Can you tell me where I can read more about their programs?
4) How much did this cost for the signs (installation, purchase, upkeep, were any stolen or other costs, etc.) for your cost/benefit analysis?
5) What did the data show relative to this study?
6) What are the drawbacks of this study?
7) What are the positive aspects of this study?
8) Who did you interview on whether this was working or not?
9) Can you (Fahd) talk to them for more information?
10) What was the final conclusion?
11) Was there any visual problems with the color of the LEDs?
12) Was there any issue with the size of the signs and letters (what was the signs)?
13) Are they going to implement the changes or leave the conventional signs?
14) Is there anyone else I should interview for information?
15) Are there any standards (ANSI, etc.) that apply so I can read more about this?
16) Any numerical data on the result of the study (less accidents, more speeding tickets, etc.)
17) Your paper shows information on the displaysbut this is about a behavioral change associated with the variable speed signs. Stay on your ergonomics subject.

Lights were LED technology in State Tested program
Benefits were to slow down traffic and ease congestion.
Drawbackseasy to see?
Easy to understand?
Message communicated?
Simulation of traffic flow with Digital signs.
What is the correct size of the signs for this activity?
Was the white background the best background?
Were the numbers big enough? Equation for measuring the size of signs. Interview a Civil Engineer?
Interview Josh Donat about the efficacy of the signsQuestions could be:
1. Were you aware of the electronic signs purpose for speed limits? Y or N

2. Did you understand the purpose of the Signs? Y or N

3. Could you see the signs in the day and night well? Y or N

4. Did this change your behavior when driving? Y or N

5. Do you think that this kind of speed control is effective? Y or N
