Map Explained

The map requires a large java script download in order to function correctly. There is no need to do anything, the download happens automatically. Download size is approximately 460KB. Download times are approximately: Dialup 1m 5s, ISDN 28s, Broadband 4s. The component is a one time download and will remain cached. Once the component has downloaded then maps will load in to the map view.


To pan the map click on the map in the area that you are interested in and drag the map to the centre of the page. Alternatively use the scroll arrows located in the top left corner of the map.
To zoom in and out of the map, position the cursor at the centre of the desired zoom position and scroll the middle mouse wheel towards the screen to zoom in and away from the screen to zoom out. Alternatively left click the in and out.
The map will then zoom to that position and area.


Over the top of some roads there is a coloured line. This coloured line represents the current recorded road speed for that section of the road. The colour of the line indicates the speed of traffic. Green signifies free flowing, yellow a slight delay, amber a moderate delay and red a severe delay.
You may notice that the overlays do not always follow the road exactly. Due to data licensing constraints we are only able to create road overlays from junction to junction.


Each icon on the map represents something that may be of interest.



There are a number of different icons shown on the map. They are listed below:
