Google Map's Real-Time Traffic Layer...

    You can now check the traffic condition on the road before you leave for work, or a party or to your friend's place. Google's Traffic layer shows the traffic conditions in your area - LIVE!!! Live traffic data is available in major cities in the United States, France, Britain, Canada and Australia, with new cities and countries frequently added. The Google Maps API allows you to add real-time traffic information (where supported) to your maps using the TrafficLayer object. Traffic information is provided for the time at which the request is made. Consult this spreadsheet to determine traffic coverage support.

    Let us now have a look at the Google Maps API - Trafiic Layer example. Copy the following code in a simple text file and save it as html. Click on this html file and it will open in your default browser. You will then see the traffic conditions in your area - LIVE...



    The output of the above code looks as seen in the result section above. The map in this example is centred at Los Angeles. Traffic Layer data in not available for India as of now. Hope it will be some day soon...
 
Traffic Color Description:
        If available in your area, real-time traffic conditions will be displayed over the road as color-coded lines. The colors indicate the speed of traffic on the road compared to free-flowing conditions. For highways, the colors roughly equate to:
  • Green: more than 50 mph or 80 kph.
  • Yellow: 25-50 mph or 40-80 kph.
  • Red: less than 25 mph or 40 kph.
  • Red/Black: very slow, stop-and-go traffic.
  • Gray: No data currently available.
          These speeds don't apply to traffic on smaller roads, such as those within cities, which have lower speed limits. For roads smaller than highways, the colors give an indication of the severity of the traffic. Green means that the traffic conditions are good, yellow means fair, and red or red/black means poor traffic conditions.

    Hi Shreerang,

    i'm pretty new to the GIS world (though I've always been using Google Maps from my mobile in India).

    I'veI've been glancing at your works. Impressive and innovative are the first 2 words that stike my thoughts when I have to describe yoru work.

    About the "Real time traffic layer", I wonder what would really be the use of this when Google maps already has it as a layer in their phone/web ?

    Hi Vishu,

    Happy to hear that you found my work impressive.

    About the "Real time traffic layer"...This is very useful as the information keeps on updating at run-time. As the traffic on a particular road increases or decreases the map layer updates itself. So you can have a look at the traffic status before you move from your place to your destination and then decide accordingly as to which route would be the best for the ride...

Where does Google get it's live traffic data from?

Referring to a post that I wrote earlier, Google’s - Live traffic Layer , ever wondered how Google collected this data? I was wondering the other day, how Google received live data to display it on their maps as a layer! I looked up the web and found something very interesting and am sharing the same with you all. As we all know, the traffic layer is available most accurately in several states in USA. Most major metro areas in the US have sensors embedded in their highways. These sensors track real time traffic data. Easy to miss at high speeds (hopefully anyway, traffic permitting), more commonly noticed may be the similar sensors that often exist at many busy intersections that help the traffic lights most efficiently let the most amount of people through. The information from these tracking sensors is reported back to the Department of Transportation (DOT). The DOT uses this data to update some of the digital signs that report traffic conditions in many metro areas. They als

The bitter divorce of PSD and HTML

    Today's article is an interesting post that I read. The original post in Portuguese and authored by Fabricio Teixeira  can be found at arquiteturadeinformacao  (Now don't ask me pronounce this =)).     Some are calling it the death of PSD  but I prefer calling it a "divorce". PSD and HTML are both healthy and living strong, just that they do not live together anymore. "PSD to HTML", which for years was the most accurate and sometimes the only right path to web design process, seems like has its days counted.     Firstly you draw a page in Photoshop; impeccable layout, representing exactly how the web pages would appear when opened in a browser. After a sign-off on this picture (PSD) from the client the front end developer transforms these pictures into HTML, CSS and Javascript. The assets are cut, one by one, exported from the PSD and integrated into the HTML. Plugins and new tools are created in the process and some companies even charge upto $1

Two maps on the same page - Side-by-side

    How good I am feeling to post a code example after such a long time! It's been all "news" over the past so many posts! Well now that I am finally doing a code example, I am posting a very highly requested code sample. Placing two Google Maps on the same page (Now that's simple you would say!), but side by side. Now this is the thing that most people struggle with. Well, implementing the second part is also very simple, as you will see in today's code.     Let's see the code. Here it is!     The output of the above code will be as seen in the result section above.     As most of you will realize, there are two maps, one centered at "Pune" and other at "Noida". Why I chose these two locations? Well, just like that!...The main issue of concern is how the maps appeared side-by-side and not one below the other as would be normal behavior of two "div" elements used in the same page. Now here is the trick! Check out the th

Geodashing...

            Geodashing!?!? Sounds something similar to Geocaching right? Well, it is! Geodashing is very similar to Geocaching in the sense that people are searching for a particular spot with only a set of coordinates as their clue.             Here's how it works. In each game, a large set of waypoints, called dashpoints, from all over the world is posted on the Web. Dashpoint locations are chosen at random by computer, with all the unpredictability that presents. Dashpoints might be in suburban neighborhoods or in the middle of wilderness areas. Then, the race is on to see who can reach the most dashpoints before the deadline.             Geodashing players can participate as individuals or as teams of up to five players to increase the number of dashpoints reached. The competition is friendly and teamwork helps to get high scores, so put your online acquaintances to good use.             Because the dashpoints are spread all over the world, it doesn't matter w

Delhi Metro's Airport Express Corridor mapped on GIS...

         The Delhi Metro's showcase Airport Express Corridor, connecting the Indira Gandhi International Airport to the heart of the Delhi, was rolled out for the public on the 23rd of February, 2011.          This is the first line in India to be mapped on GIS to enhance safety, maintenance and traffic regulation. Mapping the corridor on GIS will help in mobilising emergency services in case of a blast or fire on the train. Delhi Airport Metro Express Private Limited, the company operating the line, has mapped all the emergency services, including fire stations, police stations, hospitals, etc. along the alignment.
