You could use Unmanned aerial vehicle for real-time survey or using Google Map in satellite mode for offline mode.
Also you can ask for your colleague to stand in different location and help you.
Most of the traffic engineering department of local government have the possibility to do this, with a device crossing the streets or road. If no other solutions available, you can use video camera.
Initially the calculation needs the type of traffic pattern, like; hourly, daily, monthly and yearly counts. Then there are 5 methods for volume counts:
1. Manual (Hire a group of people to count)
2. Automatic (Traffic Counter Devices having
sensors), examples:
a) Radar Detectors (Radioactive signals
are emitted at frequencies of range
100 MHz to 100 Ghz)
b) Video Camera
c) Pneumatic Tubes (Tubes place on
roads)
d) Inductive Loops (Inductive loop
detection comprising of wires which
are embedded in road)
e) Sensors that automatically calculate
the weights of vehicles in motion,
these are called weigh-in-motion
(WIM).
Mohammadhossein Abbasi what do u mean by : Google Map in satellite mode for offline mode ... how to do it !
go to this address:
https://www.google.com/maps/
Find the street that you want to analyze on map. choose satellite mode instead of map mode.
the attachment is an example image in Berlin, Germany.
i didn't really get your idea, the google maps (in satellite mode) doesn't show you live feed it's just an image, how's that could possibly help me in counting how many vehicles passing by that specific road ?
You simply stand next to the road and count the passing cars, heavy and light, as the SPL meter is running.
Anders Buen i believe that's the easiest, the most appropriate way to do it. Thank you sir.
Dear Ali Boulemaredj,
It's easy to go to the road section that you would work, take with you a paper, draw a table and devide it on several section including heavy and light cars, bikes.. and also the time of counting. Or use your phone or two phones and take videos. After that analyze them and you must convert them in PCU or in french is ( unité de véhicule particulier).
Good luck
Mouloud Khelf Can i contact u via mail ? i have some questions that need to be answered since you have some knowledge in the subject of noise and traffic system...etc.
While Mr. Buen have the most obvious answer, I believe the traffic classification needs to be stratified a bit more than just light and heavy vehicles. In the extreme, AASHTO gives the breakdown to about 12 or 13 classes. That’s probably too much. But you can easily break down and count vehicle classes further, as suggested as follows: auto/taxi/van; motorcycle; light-duty trucks (four tires); heavy-duty trucks (six or more tires, don’t break down further by # of axles unless client specifies); buses.
Don't fret about high or low exhaust pipes for trucks for diesel vs. gas. Tandem trucks could be a separate class, but there are probably few of these.
