ALKMaps.Layer.Traffic

Create a new ALK Maps Traffic overlay.  You can display the current real-time traffic or show historical speeds based on day-of-week or time-of-day.  It has to be Spherical Mercator projection, single tile and not base layer.  In order to overlay traffic layer properly, the base layer has to use the same projection.

Examples

The code below creates a simple real-time traffice layer.

var alktraffic = new ALKMaps.Layer.Traffic("ALK LiveTraffic™", {}, {
         minScale: 500000,
         displayInLayerSwitcher: true //,
         //sphericalMercator: true,
         //singleTile:true
    });

The code below creates a traffice layer from historical data.

var alktraffic = new ALKMaps.Layer.Traffic("ALK LiveTraffic™", {
        histDay: "Friday",
        histTimeBin: "32", // 8:00 AM
        histTimeZone:  "-04:00"
    }, {
        minScale: 500000,
        displayInLayerSwitcher: true //,
        //sphericalMercator: true,
        //singleTile:true,
        //attrUseHyperlink: false
    });

Parameters

• histDay - {String} Day of the week for historical traffic data, in English, spelled out.  Case doesn’t matter, but it can’t be abbreviated.  So “Monday”, “friday” are okay.  If this or histTimeBin are blank you will get real-time traffic.
• histTimeBin - {integer} Time “bin” for the historical traffic data.  Each “bin” is a 15 minute increment, starting at midnight as bin 0.  That means there are 96 bins in total (0-95).  12:00am = 0, 12:15am = 1 ...  8:00am = 32 ...  5:00pm = 68 ...  11:45pm = 95... etc.  If this or histDay are blank you will get real-time traffic.
• histTimeZone - {String} Time zone offset, see ISO 8601 for more details.  The colon between hr and min is required.  Example: “-04:00”
