Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType

(Inherited from Object.)
Public methodRecalculateRouteTime(Directions, DateTime)
Recalculate (by accounting for traffic congestion) the time required to travel a given route (specified as Directions) starting at a given time.
Public methodRecalculateRouteTime(Directions, LatLon, DateTime)
Recalculate (by accounting for traffic congestion) the time required to complete a given route (specified as Directions) starting at a given time and given that progress has already been made to a certain point.
Public methodStatic memberRemoveTrafficFromRouteStrategy

The class is used to route through Traffic using Directions. The routing strategy can be configured using setUpRouteStrategy(RoutingStrategy).

The code below demonstrates how to use the TrafficRouting methods: RecalculateRouteTime(Directions, DateTime) and setUpRouteStrategy(RoutingStrategy)

Examples
C#
Copy
private void TrafficRoute(LatLon A, LatLon B, String dataFile) {
    // 
    // create a new Route from A to B
    // 
    Route myRoute = new Route(new RouteStop(A), new RouteStop(B));

    // 
    // create a Traffic from our XML data
    // 
    XmlReader myXmlReader = XmlReader.Create(dataFile);
    ITrafficSource[] srcs = new ITrafficSource[] { new InrixRealTimeTrafficSource(myXmlReader) };
    Traffic myTraffic = new Traffic(srcs);

    // 
    // set up a TrafficRoute and configure the strategy from myRoute
    // 
    TrafficRouting myTrafficRouting = new TrafficRouting(myTraffic);
    myTrafficRouting.setUpRouteStrategy(myRoute.Strategy);

    // 
    // set the start time for the journey. This does not have to
    // be the current time, but if you override it, make sure to 
    // convert it to UTC.
    // 
    myRoute.CurrentTime = DateTime.UtcNow;

    // 
    // get Directions between A and B, accounting for traffic conditions
    // 
    Directions myDirections = myRoute.GetDirections();

    // 
    // find the end time for the journey, given that it starts at startTime
    // 
    DateTime startTime = DateTime.UtcNow + TimeSpan.FromHours(1);
    DateTime endTime = myTrafficRouting.RecalculateRouteTime(myDirections, startTime);
