TrafficMap is a trial service designed to make available to the
public real-time traffic and travel information which is available
on HA systems. The information is gathered by Q-MISS a central database
and delivered to the TrafficMap web site via the Travel Information
Highway (TIH). The TrafficMap web site will evolve to provide additional
real-time traffic information services based on public demand and
response.
Text Based Information:
Speed Bands on TrafficMap - Average current road speed is displayed
on TrafficMap Text Information Pages as the current average speed
value and as a shaded colour. The following table provides an indication
of traffic conditions that may be expected for each of the speed
bands.

may be incomplete. TrafficMap junction information is designed to aid the
users understanding of the location of particular junctions and should not
be used for route planning.
