Through 8 °, 9 ° of north latitude）3 different routes, specially route 10, route 11, route 12；
(5) we illustrate how to determine the section of route by taking route 1 as an example：Route 1 is made of 3 sections：Yan'an 1
Road, 2 tunnel of Yan'an, 3 tunnel of Yan'an；1 section of Yan'an, 2 section of Yan'an include starting point crossing, and 3 section of Yan'an includes starting point crossing and end
Point crossing, crossings all so all by calculation to and only let it pass primary；
Using the normal distribution model of section congestion, time t used in every a road section of route 1 is calculated1,1, t1,2, t1,3;
(6) with the changed time t in 1 tunnel of the 1st section Yan'an1,1For illustrate how to establish the normal distribution mould of certain a road section congestion
Type, specific method are：
S01 determines alert time of origin at 5 points in the afternoon on the 4th of 23 seconds 6 minutes determining time informations 2017 on the September 4,17 of September in 2017
When 6 divide；
S02 obtains 1 tunnel length s=2 kilometer of section Yan'an by geographical data bank；
S03 is according to highway traffic data library, 66 machine for being segmented 1 tunnels of Yan'an when dividing i.e. September in 2017 3 days 17 when obtaining preceding 1 day 17
Motor-car average speed:6 divide four kinds of vehicle running speeds when obtaining September in 2017 3 days 17 by the speed camera on 1 tunnel of Yan'an,
Respectively：30,22,18,26, take its average value（30+22+18+26）/ 4=24, so v1=24 kilometers/hour；It obtains first 2 days
The motor vehicle average overall travel speed V on 66 pavement branch sections Yan'an, 1 tunnels when dividing i.e. September in 2017 2 days 17 when 172=25 kilometers/hour ...
The motor vehicle average overall travel speed V on 6 pavement branch sections Yan'an, 1 tunnel when obtaining the preceding same day 17 on the 180th180=25 kilometers/hour
The first n days（1=<n<=180）6 divide v kilometers/hour of average overall travel speed when motor vehicle 17
Preceding V on the 1st1=24
Preceding V on the 2nd2=25
. .
. .
Preceding V on the 90th90=24
. .
. .
Preceding V on the 180th180=20.7
S04 obtains t by t=s/v1The driving of 6 extension set motor-cars has been gone 1 road of Yan'an and has been taken at=2/24 hour=5 minutes, i.e., first 1 day 17
Between, 6 divide t the time required to the complete 1 tunnel section of Yan'an of motor line at first 2 days 172=4.8 minutes, in this way, show that alert occurs preceding 3,
6 divide t the time required to complete 1 tunnel of Yan'an of motor line at 4,5 ... 180 days 173,t4,…,t180;
ti t1, t2, t3, t4, t5, … ,t90, …, t 180
Time/minute 5,4.8,4.9,5.2,5.1 ..., 5 ..., 5.8
S05 is by μ=(t1+t2+t3+…+t180)/180=(5+4.8+4.9+ ...+5.8)/180=5,
σ2=(t1 2 +t2 2+t3 2+…+t180 2) /180-μ2=(52+4.82 +4.92+ …+5.82)/180-52=6.25,
It is X the time required to remembering complete 1 tunnel of Yan'an of motor line, it is μ=5, variance σ that X, which obeys a mathematic expectaion,2=6.25 normal state
Distribution, i.e. X~N (5,6.25)；
S06 substitutes into μ, σ
=；
Obtain specific the formula of probability density function;
S07 is by P（x《 t0）=0.9 seeks t0, specially
Make P（x《 t0）=0.9=
T is calculated by normal distribution computing module0=8 minutes, t0As the complete Yan'an of motor line 16 is divided in 1 tunnel of Yan'an at 17
The required time t that road is estimated1,1=8 minutes, the accuracy rate of the estimated time was 90%, that is, motor vehicle prolongs 8 minutes experts are complete
The probability for pacifying 1 tunnel is 90%, or says that certainty is 90%.
t1,2,t1,3The same t of algorithm1,1, do not exist together and be only that the moment：
t1,16 divide when September in 2017 4 days 17,
T again1,1=8 minutes, so：
t1,214 divide when September in 2017 4 days 17
T is calculated using the normal distribution model of above-mentioned section congestion1,2When, 11 divide when time information takes September in 2017 4 days 17,
And then calculate t1,2=3 minutes, then similar
t1,317 divide when September in 2017 4 days 17
T is calculated using the normal distribution model of above-mentioned section congestion1,3When, 17 divide when time information takes September in 2017 4 days 17,
And then calculate t1,3=4 minutes；
(7) by the changed time t in 1 tunnel of the 1st section Yan'an1,1=8 minutes, the changed time t in 2 tunnel of the 2nd section of Yan'an1,2=3 minutes, the 3rd section
The changed time t in 3 tunnel of Yan'an1,3=4 minutes;
So transit time T of route 11=t1,1+t1,2+t1,3=8+4+3=15 minute.
Because route 1 is made of 3 sections, and the used time that the probability per a road section is 0.9 is respectively 8,4,3, so whole
Probability of the used time of route no more than 15 is 09*0.9*0.9;
Similar, we can calculate route 2 ..., the transit time of route 12, T1, T2..., T12, it is assumed that we obtain one
Group transit time
Ti T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12
Unit/minute 15,17,16,20,37,44,16,15,19,18,17,16
(8) T1=T8=15 is minimum, so optional 1,8 routes, and 1,8 routes respectively have 3,4 sections, i.e. 1 route segments few therefore true
Qualitative height, therefore it is target route to take 1 route, namely it is final traffic route, corresponding security protection service station security protection 1 to choose 1 route
It is the security protection service station for providing rescue to stand.
Safety protection command system sends out instruction to 1 station of security protection, provides traffic route 1 to 1 station of security protection and provides suggestion speed
Degree, it is proposed that speed is the value of time μ, such as 1 road μ=5 minute of this example Yan'an, s=2 kilometer, μ=2/5 kilometer v=s//minute=24 public
In/hour, so obtain 2 tunnel of Yan'an, 20 kilometers/hour of the suggestion speed on 3 tunnel of Yan'an, 27 kilometers/hour, 1 station of security protection execute
Instruction is travelled along 1 tunnel of Yan'an with 24 kilometers/hour, on 2 tunnel of Yan'an with 20 kilometers/hour, 3 tunnel of Yan'an with 27 kilometers/hour
Speed travels, and fire fighting truck can reach alarm place the Yellow River mansion and sue and labour being connected in alert 15 minutes；In its 15 minutes
The probability of arrival is 09*0.9*0.9；The present invention takes 180 numerical value, and data volume is big, so gained probability value accuracy is high.It is practical
On, because the data of half a year are about 180, we can directly apply the data of half a year, deal with so more square
Just quick, it is easy to application.
Under megalopolis such as Shanghai, Central district's congestion extremely serious situation, present invention can ensure that security protection
The time that vehicle reaches scene in the case of more congestion is still controllable.
If still wanting to improve route running time certainty, the certainty of the time in each section can also be improved, such as
It improves to 0.95 etc..
