The crossing obviously concentrated of stream direction, some vehicle flowrates to position lane are significantly more, and some are very few to position lane, but
It is each sequentially to be run according to fixed timing while hardness is but still wanted to position lane, so as to cause less the consolidating to position lane of wagon flow
Determining timing much is all waste, and the fixation timing in the more multidirectional position lane of wagon flow is far from enough, is easy for causing vehicle in this way
Road congestion influences the smooth operation of traffic.
Just because of the disadvantages mentioned above of existing road traffic rules, the exploitation so many enterprises and individuals try every possible means one after another
The system and method for various traffic circulations, some have also obtained small-scale application.Such as the intelligent transportation that Mr. Ma Yun proposes
Scheme, the program also have no small progress really in the test of real road, have to save really to a certain extent and drive
The advantages of sailing time and the energy, for another example China Patent No. are the patent of invention " real-time mobile communication of ZL201210143686.0
Method of formula intelligent transportation " etc., these all have the advantages that for schemes of traffic circulation it is certain, but can be with by carefully analyzing
Know, these schemes are judged simultaneously by the acquisition to all traffic datas, and by the analysis and processing of big data
Feedback, to achieve the effect that intelligent transportation.But, these schemes are but all very dependent on the analysis and judgement of big data, and
And now for this mode reliability it is not high, and comparatively, traditional mode reliability being previously set is higher, is not easy
It breaks down, therefore, is carried out still or by the way of traditional be previously set on traffic circulation at present.But as described above,
