Options for this control allow you to specify when traffic settings to use when show traffic. By default this control displays relative traffic flow and incident data, however, you could change this behavior and show absolute traffic flow and no incidents if desired. The second control, `TrafficLegendControl`, adds a traffic flow legend to the map that helps user understand what the color code road highlights mean. This control only appears on the map when traffic flow data is displayed on the map and is hidden at all other times.
