Engineer Einjel thinking out loud:
It has been quite a while since the last time I shared some thoughts in Transportation Engineering Philippines.
Hey, President Noynoy Aquino have been in command for more than a week now. I do remember the way he mentioned in his inaugural speech that there'll be no WANG WANGs on the road anymore in his administration. Then true enough, a lot of VIPs or no VIPs, law enforcers or pretending to be law enforcers, etc who have been using devices to get pass the traffic have surendered their gadgets as said in the news report last night. I hope this will truly be implemented for the rest of P. Noynoy's term.
Then, there were a lot of road accident reports again. It's about time to have a collaborative action among motorists, traffic enforcers, public and private entities about this. Life is a gift. Let us not lose it by mere human error on the road. :)
VP Binay expressed that he will still use wang-wang. What will P-Noy do about this?
ReplyDeleteNice thought on this issue. I agree with this move of P-Noy and it will surely humble down those who are taking advantage of the power that the people has granted them.
ReplyDeleteThis is a very informative blog that you made especially for all transportation engineers. Keep it up!
By the way, is it true that there is a Rich Queen with lots of Jewels in UP NCTS? *wink* :P
Hi,
ReplyDeleteGood morning! I am a fourth year civil engineering student of Negros Oriental State University. We have a project study about Traffic Volume count in a specific intersection and investigating the capacity of the road if it can accommodate the present design. We would like to have any sample information in conducting or investigating this kind of study.
I am hoping for your response. Thank you.
P.S. You may email me at marc_thename@yahoo.com..
Da King: I do believe wang-wang should still be used by the top 2 highest positions in the country. I don't know what P-Noy will do about that.. :)
ReplyDeleteKramgil: Please refer to Dr. Ricardo Sigua's book, Fundamentals of Traffic Engineering. Everything you need is there. Conducting a volume count is very simple. :)
Thanks for the help.. I will try to look for that book..By the way, after you have conducted the traffic volume count, what will we do about the data? Well I read your blog about conducting a traffic volume and you haven't mention any methodology used after collecting the data.. However, I know that it is not necessary to put that on your blog.. But I am hoping you can tell me about that.. Thanks for the time..
ReplyDeleteGod bless you..('~'
Good day!
ReplyDeleteI would like to ask also what are the thing I have to do in investigating an intersection? Thank you.
Hi kramgil! As i said before, please do refer to Dr. Sigua's book. Its Chapter 5 is about Intersection Design and Control. Again, I believe everything you will need is already discussed there. =)
ReplyDeleteI have research the book from the internet and it was there but it was copyright so some of the pages are not there.. I will try to find it from other library because it was not available in our school.. Thanks for the help.. Good bless and more power..=)
ReplyDeleteGood day!
ReplyDeleteI found the book that you recommended and it was useful. However, the problem I want to know is not there. It doesn't discuss the analysis of traffic counting after collecting it. When you conducted the traffic counting, what steps or analyses did you use in solving the data? Have you use any program or something in analyzing it? Can you help us? We are having a hard time in researching this information. If ever we can't find it, can you give us any related topic in traffic engineering?
I am hoping to hear from you soon. Thank you.
Hi Kramgil! Hmm, did you really read the book? Section 5.5 in page 118 discusses the analysis of unsignalized intersections (i assumed unsignalized since sa province and that you already have the traffic count, i hope i'm correct) wherein you need to follow an order of analysis presented in Table 5.3 and further supported by values of critical gap (Table 5.4 and Figure 5.8) and reserve capacity (Table 5.6). There were two examples given in pages 124-128: one for T-intersection and another for four leg intersection. You just need to follow the examples which are very easy to understand. Good luck!
ReplyDeletehi Engr.,
ReplyDeleteThank you for the information you have given us. It help us a lot.
However we are now on the process of analyzing the data and the information you have told us needed Yield and Stop sign control but our intersection doesn't have any of those. Are we going to assume the road has a yield or stop signs?
we have also other question..in analyzing data, are we going to used the peak hour volume or we will just get any of the volume that we gathered?
We are hoping for your reply. God bless.
Kramgil,
ReplyDeleteyou can always assume in engineering but you should take note of your assumptions and this of course should also be valid according to engineering design and principles.. the volume used is in pcu/hr which is based on the yearly count not peak hour count. Good luck!
Kramgil, even if there are no yield signs, you can easily determine where it is best to put a yield sign by identifying the priority road among the two roads..
ReplyDeletehi Engr..
ReplyDeleteGood day...i just want to ask how to make the hourly volume count to a yearly volume count?
Thank you..
Kramgil,
ReplyDeletejust multiply it with 360 to make it yearly. you're welcome.
Please note that the traffic volume for a certain road section varies throughout the year. You may have to consider "seasonality".
ReplyDeleteFor example, doing a survey during December will yield higher traffic than usual, unlike a survey done during June (wet season)
Hi Mike,
ReplyDeleteYes, i'd have to agree with the timing of traffic survey you mentioned. Thanks for your input. Survey days should also exhibit fair weather conditions.
