Abstract

The invention provides a method for calculating the number of parking spots in a passenger station. The method for calculating the number of the parking spots in the passenger station comprises the following steps that firstly, the number of departing parking spots for departing passenger cars is calculated according to the departing requirements and the departing efficiency of the departing passenger cars; secondly, the number of departing parking spots for passing passenger cars is calculated according to the departing requirements and the departing efficiency of the passing passenger cars; thirdly, the number of all departing parking spots is obtained by adding the number of the departing parking spots for the departing passenger cars and the number of the departing parking spots for the passing passenger cars; fourthly, and the number of all parking spots is obtained through calculation based on calculation of the number of the departing parking spots according to the numerical relationship between the time for passengers to get on passenger cars and the time for passengers to get off the passengers cars. Compared with an existing standard calculation method, the method for calculating the number of the parking spots in the passenger station has the advantages that the method is more reasonable, and the accuracy of calculation of the number of parking spots can be better improved at the passenger transport station planning stage. The situation that resource waste is caused due to the fact that the parking spot utilization rate is low is avoided.

Description

Passenger station parking stall number calculating method

Technical field

The present invention relates to the parking stall number calculating method of highway bus station planning stage.

Background technology

Bus passenger terminal dispatch a car a number be weigh bus passenger terminal transmitting capacity leading indicator.For a long time, China The dispatch a car calculating of a number of bus passenger terminal all employs "<bus passenger terminal partition of the level and construction requirements>jt/t200 2004 annex a " calculating means that are given.Use and think deeply through long-term, in this computing formula, also there is Railway Project, first its Definition with regard to maximum gathered passenger number is inaccurate；Secondly calculate total amount to position of dispatching a car only with a formula, and different Parking stall operating efficiency has bigger difference, so calculates very not science.For improving parking stall utilization rate, should by dispatch a car a number with to car Position number separate computations, originate passenger vehicle dispatch a car a number and the number of dispatching a car of passenger vehicle of missing the stop also wants separate computations.

Existing passenger station parking stall number calculating method has drawbacks described above, therefore for the rule of newly-built bus passenger terminal Draw and can bring potential unfavorable factor, be unfavorable for the parking stall number needed for determination bus passenger terminal of efficiently and accurately, be likely to result in car Position number planning excessively leads to service efficiency not high, or causes parking stall number planning very few so that passenger station can not meet fortune Can demand.

Content of the invention

It is an object of the invention to overcoming the deficiencies in the prior art, provide a kind of passenger station parking stall number calculating side Method, can effectively improve the science of existing computational methods, it is to avoid parking stall service efficiency is not high, causes the wasting of resources.The present invention adopts Technical scheme is:

A kind of passenger station parking stall number calculating method, comprises the steps:

Step one, needs to calculate the number of dispatching a car originating passenger vehicle according to originating sending of passenger vehicle；

$m_s=\frac{s(1-\mathrm{\&xi;})}{{\mathrm{np\&mu;}}_s}---\left(1\right)$

Step 2, needs to calculate a number of dispatching a car for the passenger vehicle that misses the stop according to the transmission of the passenger vehicle that misses the stop；

$m_g=\frac{\mathrm{s\&xi;}}{{\mathrm{np\&mu;}}_g}---\left(2\right)$

Step 3, will originate dispatching a car a number and being added, with a number of dispatching a car for the passenger vehicle that misses the stop, position of all being dispatched a car of passenger vehicle Number；

m_f=m_s+m_g(3)

Step 4, on the basis of a number of dispatching a car calculates, calculates parking stall number；

m_d=m_fλ (4)

In above-mentioned formula (1)～formula (4):

m_fDispatch a car a number；

m_sOriginate passenger vehicle to dispatch a car a number；

m_gThe passenger vehicle that misses the stop is dispatched a car a number；

The daily hour traffic volume mean value in s passenger's traffic volume peak period；

ξ misses the stop passenger vehicle average daily passenger traffic volume and the ratio of whole passenger vehicles average daily passenger traffic volume；

In the n business hours, averagely dispatch a car number of times per hour in a position of dispatching a car；

The average rated passenger capacity of p passenger vehicle；

μ_sOriginate the ratio of guest's number and the average rated passenger capacity of passenger vehicle on the average per car of passenger vehicle；

μ_gThe ratio of guest's number and the average rated passenger capacity of passenger vehicle on the average per car of the passenger vehicle that misses the stop；

m_dTo parking stall number；

λ is to the ratio of parking stall number and a number of dispatching a car.

Further, the λ in above-mentioned formula (4) specifically took off the ratio of objective operating time and upper visitor's operating time.λ value model Enclose for 1/4～1/6.

It is an advantage of the current invention that: the present invention by originate passenger vehicle dispatch a car a number and the number of dispatching a car of passenger vehicle of missing the stop is divided Open calculating, be then added and obtain a number of all dispatching a car；Also calculate parking stall number, so as to it is overall to obtain passenger station Required parking stall number, the method is more reasonable than the computational methods in existing standard, can preferably lift automobile visitor The accuracy that the parking stall number of fortune station planning stage calculates.

Brief description

Fig. 1 is the computational methods flow chart of the present invention.

Specific embodiment

With reference to concrete drawings and Examples, the invention will be further described.

Passenger station proposed by the present invention parking stall number calculating method, comprises the steps:
