Abstract
The invention belongs to the technical field of urban traffic construction, and particularly discloses a method for determining urban traffic jam. According to the method, the average speed of the taxi or the bus on each road is calculated through real-time traffic GPS information of the taxi or the bus, and different thresholds are adopted to determine congested road sections and congested time periods according to different speed limits of different roads, so that people are reminded to detour in time, time is fully and effectively utilized by people, the utilization rate of the roads is improved well, and traffic pressure is relieved.
Description
[technical field]
The invention belongs to urban transportation construction technique field, particularly to a kind of side determining urban traffic blocking
Method.
[background technology]
Along with China's economy and the high speed development of national product power, the automobile industry of China is also in fast development.
By in by the end of August, 2011, whole nation vehicle guaranteeding organic quantity reaches 2.19 hundred million.Wherein, automobile pollution is first
Break through 100,000,000 high pointes, account for the 45.88% of motor vehicles total amount.The increase of automobile pollution and irrational highway
Building the thing followed is traffic jam issue.
As a example by Beijing: as suburb nearby 9 times of city unit are automobile pollution, Vehicle emission intensity is
5.1 times of suburb nearby.In main trunk road crossing, many places, urban district 400, peak hour motor vehicle flow exceedes
The crossing of more than 10000 has 55,5000 to 10,000 have 51, the crossing of serious crowded blocking
Reach at 99 with section.Within Three links theory in 110 turnpike roads, 80 a plurality of road traffic flow are had to reach
Saturated or over-saturation state, the Second Ring Road peak hour automobile traffic amount connecting each major trunk roads has reached more than 1.1 ten thousand
, traffic flow when Three links theory is the highest has reached more than 1.4 ten thousand.Road network peak period, midtown average
Degree of loading is more than 90%, and the average speed of 11 main trunk roads is down to 12 kilometers per hour, has nearly 1/5
Crossing and section present state of paralysis.
Alleviate traffic jam issue have become as ensure and promote socio-economic development, improve People's livelihood required it
Road.The medium-term and long-term science and technology development planning outline (2006-2020) of country, it is proposed that " development one is individual
System, i.e. modern integrated transportation system, solve three big hot issues, i.e. solve to reduce transportation and energy and consume and ring
Environment pollution problem, solution traffic safety problem, alleviation city traffic congestion problems ".At present, China big city
City faces the most serious traffic jam issue, and oneself is through having influence on the overall development level in city, alleviates traffic
Block up very urgent.Traffic congestion has been put into effect resolution, Shanghai " ten by the big city such as Beijing, Guangzhou in succession
Two or five " planning it is also proposed and controls stifled scheme accordingly.
[summary of the invention]
It is an object of the invention to provide a kind of method determining urban traffic blocking.
The purpose of the present invention is achieved through the following technical solutions: a kind of method determining urban traffic blocking, bag
Include following steps:
(1) section blocked up is determined: by the real-time traffic GPS information of taxis or buses, pass through
Calculating the average speed at every stretch of taxis or buses, the speed limit according to different roads is different,
Different threshold values is taked to determine the section blocked up；
(2) period blocked up is determined: the average speed in calculating per minute once this section, according to threshold speed
Determine the time period of blocking up.
In step (1):
The described section blocked up refers to the section that speed per hour is less than limit speed per hour 60%；
The setting of described threshold value is as follows: bus average speed is less than 60% or taxi of road speed limit
Average speed is less than the 40% of road speed limit.
Owing to bus has special public transit in peak period on and off duty, the average speed of bus is at this
Higher than private car and the average speed of taxi in period, therefore when determining public transportation road section, give taxi
Bigger weight W of average speed；This weight can be determined by machine learning.
The setting of the threshold value described in step (2) is as follows: bus average speed is less than the 60% of road speed limit
Or taxi average speed is less than the 40% of road speed limit.
The method of described determination urban traffic blocking is applicable to the section in more than two-way 4 tracks or 4 tracks.
The present invention has such advantages as relative to prior art and beneficial effect:
The present invention determines the section blocked up and the period blocked up by real-time traffic GPS information, reminds people in time
Take a devious route, be convenient for people to sufficiently effective utilize the time, the most preferably improve the utilization rate of road,
Alleviate the pressure of traffic.
[detailed description of the invention]
Below in conjunction with embodiment, the present invention is described in further detail, but protection scope of the present invention is not
It is limited to this.
Embodiment 1
A kind of method determining urban traffic blocking, comprises the steps:
(1) section blocked up is determined: obtain congested link by real-time traffic GPS information；
1) the real time GPS information of all public transport is obtained；
2) the real time GPS information of all taxis is obtained；
3) bus average speed V1 on every 3 km segment roads is calculated；
4) the average speed V2 hired a car on every 3 km segment roads is calculated；
5) when V1 less than this section speed limit V 60%, or V2 less than this section speed limit V 40% time,
Tentatively conclude that these 3 kilometers of sections are congested link；
6) centered by this section, respectively extend 3 kilometers, recalculate in this 9 kilometer range every
Bus average speed V1 ' in one kilometer, taxi average speed V2 '；
7) use step 5) method determine congested link: gather around if there being 1 kilometer of section of two continuous print to be
Stifled section, then congested link is 2 kilometers；If having 1 kilometer in the middle of two 1 kilometer of congested link
Non-block up, then using these 3 kilometers of sections all as congested link.
(2) period blocked up is determined:
Average for the congested link determined in step (1), every 1 minute calculating bus and taxi
Speed V1 ", V2 "；As V1 " less than section speed limit 60% or V2 " less than section speed limit 40% time,
This section i.e. can take into account into the period of blocking up；When within continuous 5 minutes, being satisfied by this condition, this section is i.e. entered
Enter to block up the period.
Congested link described in step (1) refers to the section that speed per hour is less than limit speed per hour 60%；
The method of described determination urban traffic blocking is applicable to the section in more than two-way 4 tracks or 4 tracks.
This method determines the section blocked up and the period blocked up by real-time traffic GPS information, reminds people in time
Take a devious route, be convenient for people to sufficiently effective utilize the time, the most preferably improve the utilization rate of road,
Alleviate the pressure of traffic.
The detailed description of the invention of present invention described above, is not intended that limiting the scope of the present invention.Appoint
What changes and deformation accordingly according to various other done by the technology design of the present invention, should be included in originally
In invention scope of the claims.
