A device that performs vehicle rerouting based on current edge speeds.
The routing-device system consists of in-vehicle devices that perform a routing and a simulation-wide (static) methods for colecting edge weights.
The edge weights container "myEdgeSpeeds" is pre-initialised as soon as one device is built and is kept updated via an event that adapts it to the current mean speed on the simulated network's edges.
A device is assigned to a vehicle using the common explicit/probability - procedure.
A device computes a new route for a vehicle as soon as the vehicle is inserted (within "enterLaneAtInsertion") - and, if the given period is larger than 0 - each x time steps where x is the period. This is triggered by an event that executes "wrappedRerouteCommandExecute".

Adapt edge efforts by the current edge states.
This method is called by the event handler at the end of a simulation step. The current edge weights are combined with the previously stored.

Returns the effort to pass an edge.
This method is given to the used router in order to obtain the efforts to pass an edge from the internal edge weights container.
The time is not used, here, as the current simulation state is used in an aggregated way.
[in] | e | The edge for which the effort to be passed shall be returned |
