The comparative analysis of step 3), new product family scheme
Demand according to transport market to freight express transportation, provided also for the high speed advantage of high-speed railway is made full use of Source, railway freight express transportation new product designs scheme, which is released, starts high-speed railway express delivery goods train and bullet train shipment soon The scheme of goods is passed, the express delivery goods train and high speed passenger train using EMUs or shipping motor-car vehicle as carrier run bar Part, the traveling of EMUs are just the same with starting high-speed railway bullet train.Simply the former in-car shipment is goods, Hou Zhecheng That sit is passenger.Therefore tissue train operation is technically feasible.Problem is:
1. existing Design of High-speed Railway specification and technical standard are not supported to start express delivery goods train;
2. the design of passenger station can not meet the requirement of passenger train shipment express delivery goods.
Therefore, tissue starts express delivery goods train, also has certain difficulty with passenger train shipment goods at present, this portion Point new product designs scheme can only be postponed carrying out.
In addition, by starting high-speed railway and speed rail express delivery goods train, passenger train ships express delivery goods Ten many indexs and the com-parison and analysis of situation (being shown in Table 1), it is found that two kinds of designs are adapting to transportation demand, service chart goods fortune Defeated time loss, reliability (percent of punctuality horizontal), freight and the scheme exploitativeness etc. of transportation have difference Reaction, speed rail express delivery cargo transport product design scheme is preferably scheme in general, should preferentially use quick iron Road express delivery cargo transport scheme.
Step 4), current exercisable new product family suggested design

It is railway freight express transportation system by above-mentioned transport product form transportation system.
The comparative analysis of 1 liang of class express delivery goods train of table
Embodiment 3:A kind of preparation method of railway fast freight traffic production scheme, contain the determination quick goods of railway The parameter step of thing transportation system;
Step 1), passenger train hot-short market reference tariff rates
With reference to tariff rates by the difference for handling operation business passenger train service speed, it is divided into 300 kilometers of high-speed railway/small When, 250 kilometers/hour, 200 kilometers/hour and 160 kilometers/hour, 120 kilometers/hour and 80 kilometers/hour of speed rail Six kinds of speed measuring and calculating.With reference to tariff rates be available for railway work out rate level when refer to, its value by with civil aviaton's cargo transport freight rate Rate and highway goods transportation tariff rates com-parison and analysis determine.
The target that freight express transportation is pursued is " fast ", and compression goods transports to the time.In goods transports to the time, including goods Thing to Zhongdao handles related operation in origin and waits the time of ready for delivery, and goods is in the way time.Due in hair, to ground Need the operation handled essentially identical, the pattern of cargo loading and transporting is also essentially identical, so managed by different Transportation Operation people, it is different The goods of means of transportation acknowledgement of consignment, this part-time gap are little.Accordingly, it is main to transport to the comparison of time for several modes goods It is comparison of the goods in the way time.In transport market, participate in express delivery cargo transport is mainly highway transportation, AIRLINE & AIRPORT and iron Transport on road.Therefore, the horizontal comparison of railway tariff rate, the mainly comparison horizontal with highway, Air Fare rate.
If transporter type goods is respectively t in the way timeBoat、tIt is public、t300、t250、t200、t160、t120And t80If difference fortune Goods represents then have in the difference of way haulage time with coefficient of variation (ρ) between defeated mode
Or
Goods can be calculated in the way time by such as following formula
L is cargo transport distance in formula, VBattalionFor overall trip speed (be Aircraft Air flying speed for air transportation, highway It is train running speed to transport as automobilism speed, railway), β is velocity coeffficient, aircarrier aircraft transport goods in the way time Refer to that aircraft leaves seat in the plane and risen and stop the whole time consumed when the seat in the plane that arrives at the airport is shut down, consider aircraft with velocity coeffficient Travel time and taken off, the influence of the additional period landed to speed index on airport;The goods of on-highway motor vehicle cargo transport exists The way time refers to from automobile is in loading station driving, and the time only on the way consumed when station reaches is unloaded to arrival, uses speed Coefficient on the way overhauls and influence of the factor such as time of having a rest to speed index in driver way in view of automobile.As usual, railway is transported It is defeated also to use velocity coeffficient index.
So, goods is in way haulage time coefficient of variation ρNavigate iron、ρRail-road, can also be calculated as follows
Or
If transporter type cargo transport tariff rates is respectively eBoat、eIt is public、e240、e200、e160、e120、e90And e60, according to goods In way time difference coefficient, railway express freight rate level can be calculated as the following formula
eIron=eBoatρNavigate ironα or eIron=eIt is publicρRail-roadα
α is the preferential coefficient of railway tariff in formula, typically desirable 0.80~0.90.
If it is 900 kilometers/hour to take Aircraft Air air speed, cargo transport tariff rates is 5.99 yuan/ton of kilometers, highway The carrier speed of service is 50 kilometers/hour, and cargo transport tariff rates level is 0.32 yuan/ton of kilometer, and high-speed railway is operated Speed is respectively 300 kilometers/hour, 250 kilometers/hour, 200 kilometers/hour, and speed rail service speed is respectively 160 public In/hour, 120 kilometers/hour and 80 kilometers/hour, civil aviaton, highway, the preferential coefficient of railway tariff take 0.9, and velocity coeffficient is all Take 0.8.Passenger train hot-short market reference tariff rates results of measuring is shown in Table 2.
The Railway Market of table 2 refers to tariff rates measure and calculate table
The favourable volume of goods transported of step 2), shipping EMUs shipping motor-car vehicle
If the seating capacity of the grade car of EMUs 2 is AVisitor 2, train operation distance is l, and number is on recent actual average per car A'Visitor 2, passenger's average riding mileage is l', then the visiting utilization rate ρ of carVisitorIt should be calculated as follows:
Accordingly, also have
A'Visitor 2L'=ρVisitorAVisitor 2l
If the tariff rates of 2 grade cars is e2, then in a train number one 2 grade car revenue from transportation EVisitor 2For

Work as EGoods≥EVisitor 2When, it is favourable that one 2 grade car, which is changed to shipping motor-car vehicle, and advantage can be written as:
PIt is dynamic=P × ρIt is dynamicOr PIt is dynamic=P × ρIt is dynamic×a
In formula:PIt is dynamicFor the favourable loading capacity of shipping motor-car vehicle;A is railway preferential price coefficient.
According to " iron is total " relevant document, when the bullet train tariff rates that speed is 300 km/h of 2 grade car that goes directly is 0.4533 yuan/passenger-kilometer, it is 0.30855 yuan/passenger-kilometer that the through speed of speed rail, which is 160 km/h, and shipping tariff rates then may be used Using according to method calculate.
If with the bullet train goods of the data compared with civil aviaton, the respectively through speed of expression 300km/h and 160km/h Tariff rates is 1.80 yuan/ton of kilometers and 0.96 yuan/ton of kilometer, and the preferential coefficient of railway tariff takes 0.90, high-speed railway and quick iron Afloat sport(s) car marking of cars loading capacity is respectively 17 tons and 20 tons, and it is 85 and 103 that day coach, which is attended a banquet and counted,.
So, if taking ρVisitor=0.6, then have for 300km/h bullet trains
PIt is dynamic=17 × 0.76 ≈ 13 (ton)
For 160km/h motor train unit trains
PIt is dynamic=20 × 0.993 ≈ 20 (ton)
This analysis, which calculates, to be shown, the favourable loading of freight waggon (P of shipping motor-car vehicleIt is dynamic) related to series of factors, it is not collinear Road should take different numerical value.P at different conditionsIt is dynamicCalculating be shown in Table 3.
The favourable useful load computational chart of the shipping motor-car of table 3
The new box car car group express delivery goods train of step 3), speed rail is weaved into
For adaptation express company different regions, the difference of different express delivery cargo transport demands, railway enterprises will provide Shipping motor-car car group composition express delivery goods train and two kinds of express goods of express delivery goods train for being made up of new box car car group Thing new product.Wherein shipping EMUs are made up of 8 motor-cars, can both have been started to be formed or started by one group of EMUs and moved by two groups The fast goods train of car group composition.
To make new box car car group express delivery goods train be protected in transport supply respect and shipping EMUs express delivery goods train Hold unanimously, increase is alternative mutually in actual shipment work, and new box car group should use and shipping EMUs identical composition Mode, i.e., a car group is formed by the new box car of 8 20 tons of loading capacity, can both have been started according to the needs of transport one it is new The express delivery goods train of box car car group, it can also start the express delivery goods train being made up of two new box car car groups.
Embodiment 4:A kind of preparation method of railway fast freight traffic production scheme, it is fast containing express delivery goods train Fast shipping service time mode step;
Step 1), express delivery goods train conveying articles transport to the time
According to the characteristics of time freight " the small flow direction of amount is scattered ", the delivery of goods has to pass through the link of consolidating the load.Fig. 1 is listed Under using speed rail operation condition, arrangement of time of the express delivery cargo transport in a workflow of place of departure two day.8:00- 18:00 is that people from a transport enterprise marketing point public business handles acceptance of freight collection ETCD estimated time of commencing discharging (tBattalion), 18:00-24:00 is Transportation Operation People handles necessary operation and short-distance transport working time (t to the same day acceptance of goodsOperation f), 00:00-24:00 be cargo loading and transporting and Train Schedule.In this work flow, key point is that lorry terminates car detention time under accumulation, in other words tOperation fAt the beginning of between point Position, it determine may the time of departure domain position and length.tOperation fThe job content that must be handled in time, and its Fig. 2 is shown in speed rail express delivery goods train activity duration process analysis.
Fig. 3 is listed using under speed rail operation condition, the time of express delivery cargo transport in Zhongdao workflow Arrange.8:00-20:00 receives the time for what consignee received, and 6:00-12:00 is Train Schedule, 12:00-18:00 is Reach the activity duration.In this work flow, key point is receive time and the t of consigneeOperation dAt the beginning of between position. tOperation dThe job content and its speed rail express delivery goods train activity duration Consumption Analysis included in time is shown in Fig. 4.
The time of departure point of step 2), express delivery goods train
Goods delivery time refers to goods consigning to consignee, and the time signed a bill by receiving.It is that Transportation Operation people makees For a transport product quality indicator, the contract of transportation responsibility promised to undertake to consignor.The promise of delivery time can promise to undertake per diem, Also can be promised to undertake by the upper and lower noon.Because requirement of the express delivery goods to " fast " word is high, it is generally desirable to can use to be sent to by morning and afternoon promise The method of time.If Transportation Operation people handles necessary operation in goods Zhongdao and sends and deliver the time needed for consignee tOperation α, it is by handling necessary activity duration (tOperation α 1) and the dispensing delivery time (tOperation α 2) two parts composition, the desired receipts of consignee ETCD estimated time of commencing discharging is [TReceive and begin, TReceive end], it is T to convey morning hand over of goods and the hand over of goods train arrival terminal station time in the afternoonTo upper、TArrive down, Computational methods are:
TTo upper=TReceive and begin+tOperation α 2Or TTo upper=TReceive and begin+tOperation d
TArrive down=TReceive end-tOperation α 2
The whole day time uses TTo upper、TArrive downDivision, can be divided into three sections.Dispatched a car a little to next day T by the same dayTo upperTo convey morning next day Hand over of goods reaches the arrival time section of train;TTo upperTo TArrive downConvey the next afternoon hand over of goods and reach train arrival time section; TArrive downTo TTo upperTrain arrival time section is reached for conveying morning hand over of goods on the 3rd.If take tOperation f=6 hours, tOperation d=6 is small When, TReceive end=20 points.Time tOperation dBy time tOperation d1And tOperation d2Two parts form, to consignee receive the goods time it is related when Between section be only tOperation d2.Accordingly it is also possible to reached to the time t of goods morning next dayOperation d1Advance to TReceive and beginCarry out before.This Scheme will shorten the time-domain of train morning next day arrival, and extend the time-domain of train arrival in afternoon, in real work It can select as the case may be.
According to the division for period of being reached terminal to express delivery goods train, speed rail express delivery goods train transport product It can be divided into three classes:
1. half reaches goods
Refer to that acknowledgement of consignment morning next day is sent to the goods of consignee up to goods within 1st.According to the operating condition on delivery of goods ground, The selection at train departure time point, run with 160km/h speed, goods of the haul distance in 500 kilometers to 1000 kilometer ranges can It is sent to realizing half.
2. one reaches goods
Refer within 1st carry the goods that is sent to of the next afternoon up to goods.Run with 160km/h speed, haul distance 1000- Goods within 1800 kilometers, which can all be realized one, to be reached.
3. reach goods on time
The punctual goods for referring to that be sent in the 3rd day morning of acknowledgement of consignment up to goods.Goods of the haul distance within 4000 kilometers can be with Realization reaches on time.
Above-mentioned three classes goods, the quality level of transport is identical, because haul distance it is different transport to time difference.But It is generally not railway express up to the haul distance of 3000-5000 kilometers from haul distance for the adaptability of railway express cargo transport The favourable scope of goods.Meanwhile in China's haul distance in the two intercity of 3000-5000 kilometers, express delivery goods freight volume is general also not The condition for starting express delivery goods train can be met.Therefore, for the 3rd day transport product transported to, in railway express goods train In starting scheme, new product designs scheme can wouldn't be included in.
Step 3), express delivery goods train time of departure domain
The time of departure, domain referred to ensure the train run with certain speed, and in the range of the regular hour, operation is certain Distance, reach the train departure time range of terminal station.
If the every T of the beginning and end in time of departure domainHair begins、THair end[T can then be usedHair begins、THair end] time of departure domain is represented, if It is T that express company, which starts to handle the activity duration,Operation is begun, then the starting point in time of departure domain can determine as the following formula
THair begins=TOperation is begun+tOperation f
TOperation is begunUsually outlet terminates the initial point after operation, but for the big express company of portfolio, according to need It can also be advanced in the business hours.The time of departure terminal in domain can be calculated as follows
Or
In formula:TTo end--- reach the terminal of the time-domain of goods train;
L --- train operation distance;
V --- train running speed.
For speed rail, due to not setting fixed skylight time, time of departure domain [THair begins、THair end] it is a continuous-time domain, Under this condition, if carrier's business hours are to 18:00, take tOperationFor 6 hours, then the train earliest time of departure was 24:00. Accordingly, intend " reaching for 1st " train running time on the way can have 8 hours, that is, generally 1280 kilometers of transportation range (lorry group) or In the range of 960 kilometers (box car groups).If the goods train that train starts in section is multiple row, it is also an option that wherein one row or Two row are dispatched a car in advance, such as are advanced to 18:00 dispatches a car, and at this moment can has 14 hour Train Schedules before early 8 points, transports Away from up to 2240 kilometers or 1680 kilometers, so as to substantially prolongs the spatial dimension of " reaching for 1st " transport product.
The relation of Train Schedule and transportation range refers to table 4.
The express delivery goods train run time of table 4 with apart from represent table
Embodiment 5:A kind of preparation method of railway fast freight traffic production scheme, it is fast containing establishment speed rail Pass goods train starting scheme and timetable and passenger train Shipping step;
Step 1), speed rail express delivery goods train transportation movement requirements data table
Transportation movement requirements data table is started according to express delivery freight exchange scaling between passenger station for establishment express delivery goods train Scheme provides master data.
The establishment of step 2), express delivery goods train initial scheme
Weaving into for speed rail express delivery goods train can both use locomotive traction 160km/h lorry groups, can also use new Type box car car group, both modes are consistent in terms of goods train technical conditions are started, and it shows as:
1. weaving into for car group is 8;2. the loading capacity of vehicle is 20 tons;3. car group is fixed marshalling circulating and used;④ Identical is required to loading-unloading vehicle condition.
But also there is difference, show as:
1. for the lorry group speed of service up to 200 km/h, through speed can be by 160 km/h of calculating, new box car fortune Scanning frequency degree is 160 km/h, and through speed can only be by 120 km/h of calculating.
2. lorry prescription case cost of transportation is higher.
Therefore, two kinds of group schemes of express delivery goods train, it is identical that train, which starts planning device,.In actual work , can be according to the transportation demand of express company, from any Train formation solution in work.
The principle of establishment is:
1. the influence to speed rail train is reduced as far as possible;
2. start 1 row as far as possible or multiple row can ensure that express delivery goods train of the realization " reaching for 1st " for target.
Therefore, the express delivery goods train of long marshalling should be started as far as possible, at the same for extend realize the conveying of " reaching for 1st " away from From, condition may in the case of, should terminate in advance goods assembly, handle cargo service, certain distance can be run before striving at 24 points.
According to express delivery goods freight volume data, under conditions of every group of EMUs (box car group) is made up of 8 cars, can calculate respectively Determine the wagon loading of each passenger flow district.
Average daily wagon loading (Nij)
In formula:PFast ijThe express delivery freight exchange amount between ij passenger stations;PDressFor the average tons loaded of express delivery goods per car, for Speed rail shipping motor-car vehicle and box car are desirable 20 tons.
Express delivery goods train starts train number (car group number) nJi is fast
In formula:mIt hurry up--- number of cars in a train;
The integer part of a --- result of calculation, that is, start train number;
The fractional part of b --- result of calculation, i.e., remaining wagon loading part (Δ Nji), Δ Nji=b × mIt hurry up
Step 3), determine that passenger flow district starts express delivery goods train number
In order to ensure the unimpeded operation of express delivery train, it is necessary to which the handling capacity of speed rail section should not be surpassed using state Cross catatonic type state, speed rail handling capacity is shown using state analysis research, type handling capacity in short supply using state with Saturation type handling capacity is capacity utilization ratio 90% using the separation of state, that is to say, that generally, speed rail visitor Stream section handling capacity utilization rate must be controlled 90% and its less.
If it is n to start express train number as defined in certain passenger flow district route map of trainVisitor, handling capacity n, intend in the section The express delivery goods train number started is nGoods, then have:
It can thus be concluded that the express delivery goods train number that the passenger flow district allows to increase is:
nGoods≤0.9n-nVisitor

Express delivery cargo transport transport market is the sub- market after the market segments, but it is current most active, with fastest developing speed, hair It is big to open up space, the best transport market of economic benefit.Since railway enterprises just lose ginseng closing down less-than freight traffic With the status of express delivery cargo transport market competition, though start to pay attention to this transport market in the recent period, it is total optimal because just losing Express transportation market development and the opportunity of development, and railway is in a disadvantageous position in this market in express delivery cargo transport.Face This market situation, railway specialized company, which undertakes express delivery goods business, can two ways:
1. whole process undertakes express delivery
Whole process is undertaken express delivery refers to accept delivery since owner of cargo's hand to the transportation being sent to based on consignee, Therefore, railway specialized company, it is necessary to marketing network is set in the both ends city, with certain density arrangement's marketing network, built The facilities such as sortation hubs.
2. undertake long-distance transport business
Express delivery goods for strange land, two intercity long-distance transports are generally public by railway carrier and highway transportation Department undertakes.Under the actual conditions in China, the main transport enterprise by road of express company's goods long-distance transport at present and aviation fortune It is defeated to undertake, but still have certain demand to railway transportation.
Currently, the market manifestation of express delivery cargo transport is the developing state of the concentration in terms of two, i.e. cargo transport demand Region collection neutralize the concentration for undertaking express delivery express company.It is preceding by taking the national express delivery goods business freight volume of 2015 as an example 50 city portfolios account for the 86.9% of total amount, and the first two 15 city portfolio accounts for 73.0%, and preceding ten cities just account for 45.9%.It can be seen that the social economy that express delivery amount is concentrated mainly on minority is flourishing, in the higher business of living standards of the people The heart, cultural exchange centre city.In addition, the portfolio undertaken in the thousands of express company in the whole nation, is concentrated mainly on again In more than ten nationwide big express company's hand.This kind of company is substantially in China, complete by different modes Marketing network layout and configuration are completed into the construction of forwarding net and in city or geographic coverage, and is being planned large-scale Among construction of the logistics center.The primary stage that railway develops in express transportation, take absolutely and close down less-than freight traffic business, On the one hand this transport market has been automatically exited from equivalent to railway, favourable development space is provided for express company's business, is pushed away Enter the development of express delivery, on the other hand also result in the discarded of the infrastructure such as railway less-than freight traffic equipment.Should Point out, express delivery cargo transport develops into the level of today, and railway is want to reenter this market in a manner of original, re-establishes fortune Defeated service network and marketing network, the equipment for reconfiguring indispensability are very difficult, it is impossible to occupy the larger market share.
According to the General Principle of Transportation marketing, for a transport enterprise, whether certain segments market valuable Value, depends primarily on the race condition for transporting sub- in the market and transportation demand.Transportation demand scale is although larger, but competes Very fierce market, or competition are not bery fierce, but transportation demand is not that very high sub- market does not all have value.Railway specialty Carrier had both been want in the big city of transportation demand, want, in the little city of transportation demand, to carry out express transportation business comprehensively again Plan, it is clear that prospect may not be optimistic.
The strange land express delivery goods long-distance transport that express company undertakes, in theory should by road, railway, the transport such as civil aviaton Mode undertakes, and equipped with certain highway, AIRLINE & AIRPORT equipment, is not most economical favourable transport for current portions express company Mode.In terms of development angle, it is advantageous that railway, which participates in express delivery goods long-distance transport market competition,.Accordingly, railway participates in fast Pass cargo transport market competition, in a manner of using and participate in long-distance transport business based on, undertake supplemented by whole business in the way of for Preferably.
As described above, embodiments of the invention are explained, as long as but essentially without this hair of disengaging Bright inventive point and effect can have many deformations, and this will be readily apparent to persons skilled in the art.Therefore, this The variation of sample is also integrally incorporated within protection scope of the present invention.
