The cumulative and larger direction in position is leading.If Position_SN<Position_EW, show north-south two to road not by ten
Word crossing vehicle it is overall relative to Dong-west two on road not by the vehicle of crossroad closer to crossroad, then north-south
Two first pass through to road vehicle in this scheduling grand cycle;Otherwise, Dong-west two is integrally relative not by crossroad vehicle to road
In north-south two on road not by the vehicle of crossroad closer to crossroad, Dong-west two is to road vehicle in this scheduling
The grand cycle first passes through.Thus, four sections of respective durations of timeslice and order are determined in traffic scheduling time window.Finally, sentence
Disconnected vehicle direct of travel whether with current time in above-mentioned operation result residing for timeslice can passing road direction be consistent,
Drawing could send in grand two sections of timeslices of cycle by the result of crossroad, and by order that is corresponding current or stopping
Traveling control module.
8. self scheduling and traffic congestion can be achieved and perceive the intelligent vehicle control according to claim 7 based on Internet of Things
System, it is characterised in that:The adaptive decentralized dispatch module need to judge timeslice residing for current time.Specific method is, from
The timing since traffic scheduling time window initial time t0 of adaption scheduling algorithm, clocking value t.The grand cycle T of the scheduling and each
Scheduling time piece duration is it has been determined that i.e. traffic scheduling time window sliced time point t1, t2, t3 is determined.IfIt can then sentence
It is disconnected to be currently at first passage timeslice;IfIt then can determine whether to be currently at second channel timeslice;IfIt then can determine whether to be currently at third channel timeslice;IfIt then can determine whether to be currently at
Fourth lane timeslice.
9. self scheduling and traffic congestion can be achieved and perceive the intelligent vehicle control according to claim 1 based on Internet of Things
System, it is characterised in that:Also message information can be encrypted for the wireless internet of things communication module, and the process of encryption is as follows:
By the identification to message identifier, message classification screening is carried out, then solution is encrypted to message data section from AES
It is close.
10. self scheduling and traffic congestion can be achieved and perceive the intelligent vehicle control according to claim 9 based on Internet of Things
System processed, it is characterised in that:The AES can be DES algorithms or aes algorithm.
