End is positioned, and mobile terminal is belonged to every street, that is, obtains the real-time road in street.Compared to the prior art, originally
Invention process is simple, ingenious in design, can know that every street is unimpeded or crowded at a glance.
In one embodiment, the step S1 includes：
Center line in the streets ArcGis Shang You radiates certain geographic range to street both sides, and set is located at the geographic range
Interior all base stations are as first kind base station.
ArcGis is a kind of GIS platform product, has powerful cartography, spatial data management, spatial data integration
And the ability of spatial analysis, it is the common tool software of those skilled in the art.
Fig. 2 shows the schematic diagram of screening first kind base station, dotted line frame indicates the geographic range of radiation, trident table in figure
Show base station, which radiated from the center line in street to street both sides, although there are many base stations, ground in Fig. 2
Seldom a part of base station is contained only in reason range, this is to ensure that the division of first kind base station is accurate, and selection is all edge
The base station of street both sides setting is not all selected as remote off-street base station.
In one embodiment, when in the geographic range radiated for the first time without finding base station, spoke can further be expanded
The geographic range penetrated, for example, original radiation scope is street both sides 5m, then the radiation scope after expanding can be 10m, if
Base station is had not found, then further expands radiation scope, until finding the base station by street.
In one embodiment, although some base stations on map not in radiation scope, certain fans of base station
Area may generate coincidence with coverage area, and therefore, step S1 also needs to find out the base station in a certain sector ownership street, to base station
Sector face and grid surface carry out intersection operation and judge the sector face ownership street of the base station when intersection reaches certain threshold values.

MR.AOA.01, angle ° range are 5-10 °, such as when there is MR.AOA.71, that we know that mobile terminal compared to due north
Direction is between 355 ° -360 °.
TA values：Maximum time lead, i.e. mobile terminal signal reach the time of base station and assume the mobile terminal signal
With base station distance be 0 when mobile terminal reach base station time difference.
Table 2 is the mapping table of TA values and base station range
As shown in Table 2, each TA value has corresponded to the maximum distance and minimum range of base station range, such as when TA values
When being 100, you can know that base station range is 7812-7890.12m.

The relationship of base station sequence group is stated, several ends for obtaining corresponding each master base station select mobile terminal, the whole choosing movement of all master base stations
The summation of terminal is the quantity of the mobile terminal on street.
If street direction is North and South direction, base station is in the left and right sides in street, when the master base station of mobile terminal is in street
The AOA values of left side (being seen towards street north orientation) so mobile terminal are greater than MR.AOA.00 and are less than MR.AOA.36, if master base station
Right side in street, then the AOA values of mobile terminal, which are greater than MR.AOA.36, is less than MR.AOA.71；
If street direction is east-west direction, when the master base station of mobile terminal is in the left side (towards street west to seeing) in street,
The AOA values of so mobile terminal are greater than MR.AOA.54, are less than MR.AOA.18.Similarly calculate other directions.
Meet the population that conditions above is assured that on every street.Because MR data transmit a data per 480ms,
Therefore urban traffic situation can be accomplished quasi real time to show.
