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.

  1. 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 ?

  2. 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...

Playing with the markers and info window bubbles...

    In the last few posts, we have seen some marker examples and some information window examples. Now, lets do something interesting combining these two things. Just writing that "This is an info window" in the information bubble is not very interesting! And I know this...Have gone through the same phase!     So, today we will do something interesting! We will display the latitude- longitude co-ordinates of the point that the user clicks on the map! Doing this is not at all complex! Copy paste the following code and you will see for yourself a map coming to life!     The output of the above code looks as seen in the result section above! If you have any queries regarding the above code please comment on the blog post or feel free to contact me at my mail ID .

Retriving co-ordinates...

         We have seen 2 Google Maps API v3 examples wherein we have retrieved the latitude-longitude co-ordinates of the point of click on the map. In the first example we have displayed the co-ordinates in the information window and in the second , we have displayed the co-ordinates in a form in the information window.         Today we will create a code to retrieve the latitude longitude co-ordinates in a text box while simultaneously a marker appears on the map as well. So, here goes the code. <html> <head> <title> Google Maps API v3 - Adding marker on Click and retrieving the co-ordinates in a text box </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using event as a parameter to a function declare map, strictly as a global variable fun...

Form info window

         Today we will look at a Google Maps API v3 example to add a form in the information bubble! This is usually required when we wish to accept some data/information from the user! This data can be saved to a server in the form of an XML file or a database! The information can then be retrieved back at a later stage, when necessary!          In this example we will only look at form in the information bubble! The connectivity part with the server will be discussed in another post! So, today's code snippet is as seen below! <html> <head> <title> Google Maps API v3 - Adding marker and info window on Click and creating a form in the infowindow with the lat-lng information in it. </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using ev...

Jquery Mobile - Theming listview icons

    After exploring all the standard listview types in the series of examples on listview, you must have observed that for a linked list, Jquery Mobile displays a standard "arrow-r" icon to the extreme right of the list. However, you don't want the standard "arrow-r" icon and you need some custom icon there.     Jquery Mobile provides a set of icons that can be used along with listviews in place of the standard "arrow-r" icon. To override the standard icon, set the data-icon attribute on the desired list item to the name of a standard icon. We will see a complete list of icons in the following example.     However, before proceeding to the example, let us also consider a case where we do not wish to have any icon on the list item. This too can be achieved by setting the value of data-icon attribute to false. We will also include this in our example that follows.     Hope you have followed this post. Do drop a line in case you fi...
