Equal to 40km/h, then congestion status is defined as normally travel.
In some embodiments, congestion status can only have two kinds, i.e. congestion or normally travel, congestion status and normally travel
Under state, the interval time that each roadside unit sends wake-up signal is different, and the time interval set under congestion status is more than just
Time interval under normal transport condition.
Certainly it can also flexibly be formulated according to specifically used scene, the quantity of congestion status and specific interval time, in a word, gathered around
Stifled degree is more serious, and the interval time that each roadside unit sends wake-up signal is longer.
In addition, the determination on very first time value, the second time value and the 3rd time value, below with an example for
It is bright：
For ETC electronic tags, about 40 meters of the two-way communication region distance of antenna, for 5.8G composite cards, antenna leads to
Believe that region distance is more than 40 meters, so according to small communication zone apart from calculating limit value, communication zone is apart from value len=40
Rice.The vehicle body of general car is about 4-5 meters, it is assumed that automobile vehicle commander's car_len=4.5 rice, complete once completely to identify when
Between trade_time=160ms (since being received VST to receive SETMMI response terminate be identified time).It is assumed that bst_cnt
=3 BST can wake up toll tags.
When congestion in road is serious, it is assumed that car speed 20km/h, the interval between car and car are at least 5 meters, one
The maximum vehicle number in track is：Len/ (car_len+5)=4.Most 4 Emergency Vehicle Lanes of track+1 (one of general highway
As car do not allow to walk Emergency Vehicle Lane), then, the vehicle number of a section is：4*4=16, complete the exchange hour of 16 cars
For：16*trade_time=2560ms.In 40 meters of communication zone cross the car time be：40m/ (20km/h)=7200ms.
Each car merchandise once, residue send wake-up signal time be：7200-2560=4640ms, therefore, send wake-up signal
Interval time is：4640/16/bst_cnt=97ms.
When congestion in road is general, it is assumed that car speed 40km/h, the interval between car and car are at least 10 meters, one
The maximum vehicle number in track is：40/ (car_len+10)=3.Most 4 Emergency Vehicle Lanes of track+1 (one of general highway
As car do not allow to walk Emergency Vehicle Lane), then, the vehicle number of a section is：4*3=12, complete the exchange hour of 12 cars
For：12*trade_time=1920ms.In 40 meters of communication zone cross the car time be：40m/ (40km/h)=3600ms.
Each car merchandise once, residue send wake-up signal time be：3600-1920=1680ms, therefore, send wake-up signal
Interval time is：1680/12/bst_cnt=47ms.
When road is normal, it is assumed that car speed 100km/h, the interval between car and car are at least 20 meters, a car
The maximum vehicle number in road is：40m/ (car_len+20)=2.Most 4 Emergency Vehicle Lanes of track+1 of general highway are (general
Car does not allow to walk Emergency Vehicle Lane), then, the vehicle number of a section is：4*2=8, complete the exchange hour of 8 cars：8*
Trade_time=1280ms.In 40 meters of communication zone cross the car time be：40m/ (100km/h)=1440ms.Each
Car merchandise once, residue send wake-up signal time be：1440-1280=160ms, therefore, send the interval of wake-up signal
Time is：160/8/bst_cnt=7ms.
It is last it should be noted that, when the settled speed of traffic law is more than or equal to 100km/h, the safe distance between car and car
For more than 100 meters, during less than 100km/h, at least more than 50 meters of safe distance, it is actual in communication zone without so more cars
, transaction time is less, and therefore, case above simply does an extremum estimation.
