Returns the information whether this link is blocked Valid after the vehicles have set their requests.

Parameters
[in]arrivalTimeThe arrivalTime of the vehicle who checks for an approaching foe
[in]leaveTimeThe leaveTime of the vehicle who checks for an approaching foe
[in]arrivalSpeedThe speed with which the checking vehicle plans to arrive at the link
[in]leaveSpeedThe speed with which the checking vehicle plans to leave the link

[in]impatienceThe impatience of the checking vehicle
[in]decelThe maximum deceleration of the checking vehicle
[in]waitingTimeThe waiting time of the checking vehicle
[in]collectFoesIf a vector is passed the return value is always False, instead all blocking foes are collected and inserted into this vector
[in]lastWasContRedWhether the link which is checked, is an internal junction link where the entry has red
Returns
Whether this link is blocked
Note
Since this needs to be called without a SUMOVehicle (TraCI), we cannot simply pass the checking vehicle itself
