Description
Technical field
The invention belongs to field of traffic control, particularly relate to a kind of improve dispatching a car of public transport punctuality rate
Interval optimal control method.
Background technology
Public transit system is that its service quality is increasingly by people towards popular social service system
Concern.Quickening along with people's rhythm of life, it is ensured that the punctuality rate of bus just seems meaning
Justice is great.And existing can guarantee that the city line proportion that public transport arrives at a station on schedule is little, this is not
Only can destroy normal driving order and also have influence on the trip of passenger.
At present, the countermeasure improving public transport percent of punctuality mainly has that public transport right of way is preferential, traffic signal are excellent
Elder generation and set up fast public traffic system.But according to traffic department's introduction, traffic congestion is just to affect public transport
The main cause of some rate.In recent years, owing to the private car increased severely has tied up limited path resource,
Public transport operation speed reduces further, and the circuit average turn-round rate of rolling stock declines, and difficulty on schedule of driving a vehicle strengthens.
So for more common bus, when the traffic in the face of extremely blocking up, public
Friendship is preferential, traffic signal preferentially do not ensure that its punctuality rate.It is thus desirable to one is for poor
The method improving public transport punctuality rate of road situation.
Summary of the invention
The problems referred to above of present invention prior art to be overcome, propose a kind of public transport punctuality rate that improves
Departure interval optimal control method.
The inventive method is mainly for the jam situation of road peak period, by suitably improving
Departure frequency, and adjust the departure interval according to the change of different periods congestion, formulate more
Reasonably departure plan.
For reaching above-mentioned purpose, the technical solution used in the present invention is as follows:
Bus departure control method, including:
Step 1. utilizes mobile satellite location equipment to gather the moment T of bus arrivalij, compare timetable
Calculate late time difference Δ Tij=| tij-Tij|, set up Δ TijSet R;Wherein, TijRepresent reality
In i-th class of bus arrive time of jth website, tijRepresent in public transport timetable and specify
I-th class of bus arrive time of jth website, Δ TijRepresent that i-th class of bus is in jth
The late time difference of website;
Step 2. statistical data analysis set R, during according to the congestion level of road to bus departure
Between carry out Time segments division;
Step 3. sets up departure interval model, repartitions the departure interval within the period;
Temporal information T that step 1 is collected by step 4.ijSubstitute into model calculates the departure interval with
Formulate departure plan.
Wherein, the statistical data analysis set R described in step 2, according to the congestion level of road
The bus departure time is carried out Time segments division, particularly as follows:
2.1 useStating the important parameter of road traffic congestion degree, m represents this
Circuit bus station sum, Δ TiRepresent that i-th class of bus is total in the late time difference of all websites
With, its value shows that the most greatly road situation is the poorest;
2.2 according to order of dispatching a car, successively by Δ T2、ΔT3、ΔT4... with Δ T1Make comparisons, will meet
|ΔTi-ΔT1|≤t with Δ T1It is divided into a set (Δ T1,ΔT2,…ΔTd), threshold value t is to divide collection
The index of conjunction scope, the difference size element less than t belongs to a set, Δ TdIt it is first
The end element of set, d is the element number of set 1;Then with the end element in set it is
Comparison other in kind divides next set, as with Δ TdSecond is divided for comparison other
Individual set;Repeat said process, until being some set by all numerical division
Rc=(Δ Tl,ΔTl+1,…ΔTl+q-1) wherein RcRepresent the c set, Δ TlFor set the first element,
ΔTl+q-1For the last bit element of set, l is the first element train number of set, and q is the element of set
Number;
2.3 with corresponding to Δ T1And the T at the time of departure of the public transport train number of each set end element1、
Td、Tl、Tl+q-1As the separation of division period, thus obtain some [T that dispatches a car the periodl,Tl+q-1]。
Wherein, described in step 3, set up departure interval model, repartition within the period and dispatch a car
Interval, particularly as follows:
3.1 according to timetable, calculates ideally, the head office of each train number in the same period
Journey time sumtimLast is arrived in timetable i-th class of bus
The time of individual website, n represents the sum of dispatching a car in this period;
3.2 according to the actual information gathered, and calculates under practical situation, and in the same period, each train number is total
Journey time summationTimLast is arrived in reality i-th class of bus
The actual time of individual website;
3.3 definition KsEncrypt coefficient for departure frequency, characterize the raising degree to departure frequency,
Then
The departing time interval of 3.4 optimizations being calculated this period
The invention have the advantage that the defect that compensate for improving public transport punctuality rate conventional method, can have
The late phenomenon of public transport that power reply traffic jam causes;To actual public transport operation data statistics meter
Calculating the personal experience that instead of dispatcher, more science is accurate;To divide the time of departure,
Arranging an order according to class and grade at times, the formulation making departure time-table is more reasonable, improves public affairs to a great extent
Hand over service level.

Detailed description of the invention
Referring to the drawings:
Bus departure control method, including:
1. utilize mobile satellite location equipment to gather the moment T of bus arrivalij, comparison timetable calculates
Late time difference Δ Tij=| tij-Tij|, set up Δ TijSet R.Wherein, TijRepresent in reality i-th
Class's bus arrives the time of jth website, tijRepresent i-th specified in public transport timetable
Class's bus arrives the time of jth website, Δ TijRepresent that i-th class of bus is at jth website
Late time difference.
2. statistical data analysis set R, enters the bus departure time according to the congestion level of road
Row Time segments division.
3. set up departure interval model, within the period, repartition the departure interval.
4. temporal information T step 1 collectedijSubstitute into and model calculates the departure interval to formulate
Departure plan.
Wherein, the statistical data analysis set R described in step 2, according to the congestion level of road
The bus departure time is carried out Time segments division, particularly as follows:
