) const
inherited

Returns the leader and the distance to him.

Goes along the vehicle's estimated used lanes (bestLaneConts). For each link, it is determined whether the vehicle will pass it. If so, the subsequent lane is investigated. If a vehicle (leader) is found, it is returned, together with the length of the investigated lanes until this vehicle's end, including the already seen place (seen).

If no leading vehicle was found, <0, -1> is returned.

Pretty slow, as it has to go along lanes.

Todo:
: There are some oddities:
  • what about crossing a link at red, or if a link is closed? Has a following vehicle to be regarded or not?
Parameters
[in]distThe distance to investigate
[in]seenThe already seen place (normally the place in front on own lane)
[in]speedThe speed of the vehicle used for determining whether a subsequent link will be opened at arrival time
[in]vehThe vehicle for which the information shall be computed

Tries to insert the given vehicle.

The insertion position and speed are determined in dependence to the vehicle's departure definition, first.

Then, the vehicle is tried to be inserted into the lane using these values by a call to "isInsertionSuccess". The result of "isInsertionSuccess" is returned.

Parameters
[in]vThe vehicle to insert

Tries to insert the given vehicle with the given state (speed and pos)

Checks whether the vehicle can be inserted at the given position with the given speed so that no collisions with leader/follower occur and the speed does not cause unexpected behaviour on consecutive lanes. Returns false if the vehicle can not be inserted.

If the insertion can take place, incorporateVehicleis called and true is returned.

Parameters
[in]vehicleThe vehicle to insert
[in]speedThe speed with which it shall be inserted
[in]posThe position at which it shall be inserted
[in]recheckNextLanesForces patching the speed for not being too fast on next lanes
[in]notificationThe cause of insertion (i.e. departure, teleport, parking) defaults to departure
Returns
Whether the vehicle could be inserted
