Navigation
To display traffic information for a particular incident just hover your mouse pointer over a triangle and the details for that incident will be displayed in about a second. Small green circles will show that it is coming.
Use the zoom bar to zoom in or out for more or less detail. Use (+) to zoom in or (-) to zoom out. Alternatively if you have a scroll wheel on your mouse you can use that to zoom in and out quickly. Each click or roll roughly halves or doubles the scale.
To centre an incident on the map double click on the incident marker you would like to centre on.
To move around the map or your proposed route, you can use the arrow keys on your keyboard, or when the hand is showing for your mouse pointer, you can left click and hold to move the map around.
