Description

一种城市轨道交通路网运输能力仿真计算方法和系统 An urban rail transit network transport capacity calculation and simulation systems

技术领域 FIELD

[0001] 本发明涉及城市轨道交通的仿真计算方法。 [0001] The present invention relates to the calculation method of urban rail transit simulation. 更具体地,本发明涉及一种城市轨道交通路网运输能力仿真计算方法和系统。 More particularly, the present invention relates to an urban rail transit network transport capacity simulation methods and systems.

背景技术 Background technique

[0002] 目前,国内外计算城市轨道交通路网运输能力的方法较少,主要是以线路能力计算为背景,没有从路网整体角度考虑。 [0002] At present, domestic and foreign calculation method is less urban rail transit network transport capacity, mainly in the line capacity is calculated as the background, no consideration from the perspective of the overall road network.

[0003] 已有的计算方法中,路网运输能力计算以图解法和分析计算法为主,图解法是通过计算机或者手工模拟运输生产实际情况铺画列车运行图,从而确定路网运输能力的方法。 [0003] The conventional calculation method, the transport capacity of the road network and computing diagrammatically Analysis calculated based method, computer graphic method or by hand to simulate the transport actual production shop train graph, to determine the road network transport capacity method. 该方法较直观,但是计算量大,计算过程繁琐,且计算结果因人而异。 This method is more intuitive, but computationally intensive, complicated calculation process, and the results vary. 分析计算法是在对实际情况进行分析研究的基础上,通过建立数学模型,利用数学公式计算路网运输能力的方法。 Analysis and calculation method is based on the analysis of research on the actual situation, through the establishment of a mathematical model, using the mathematical formula to calculate the transport capacity of the road network. 分析计算法计算简便易行,通用性强,但是对研究对象和影响因素都进行了一定的简化处理,并且其结果对模型的依赖性较大,当模型较为复杂时,使用分析计算法求解的结果可能与实际结果相差较大,准确性不高。 Analysis calculated calculation method is simple, versatile, but the object of study and have carried out certain factors simplified process, and as a result a large dependence on the model, when the model is complex, using the computing method of analysis the results may be quite different from the actual results, the accuracy is not high.

[0004] 并且,客流特征作为路网运输能力的影响因素之一,在路网运输能力计算中起着重要的作用,但是图解法和分析计算法对客流的时间和空间特性都不能进行很好的刻画, 而计算机仿真方法能够充分模拟行人在城市轨道交通网络中出行的情况,与实际情况比较接近。 [0004] and, wherein one of the passenger transport capacity of the road network as factors, play an important role in the transport capacity of the road network in the calculation, but the analysis and the calculation method illustrated in temporal and spatial characteristics of the passenger are not well characterization, and computer simulation can fully simulate pedestrian travel in urban rail transit network, closer to the actual situation.

[0005] 另外,服务水平即乘客感知到的服务质量,该服务水平也影响着路网的运输能力。 [0005] In addition, the level of service that is perceived quality of passenger service, the service level also affects the transport capacity of the road network. 因为仅从客观的角度来看,路网系统还能再增加运输的乘客数量,但从乘客的主观角度来看,拥挤程度已经达到其容忍的极限,其他乘客不能再进入系统中。 Because only from an objective point of view, the road network but also to increase the number of passengers transported, but from a subjective point of view of passengers, overcrowding has reached the limit of its tolerance, other passengers can no longer enter the system. 而已有其他方法在计算路网运输能力时,没有考虑服务水平的要求,因此计算结果可靠性偏低。 Only there are other ways in the calculation of road network transport capacity, without considering the level of service required, and thus the reliability of the results is low.

[0082] 在进行仿真的过程中,为了便于在步骤6中将每次加载到路网中的增量客流分配到各个od对上,客流的od分布表可以变形为客流的od分布比例矩阵,如下: [0082] In carrying out the process of the simulation, in order to facilitate loading in step 6 to each increment of road network traffic allocated to each pair of od, od distribution table can be deformed into a passenger traffic distribution ratio od matrix, as follows:

[0083] [0083]

[0084] 假设该路网的总客流发生量为0,即 [0084] assume that the total traffic of the road network generation amount is zero, i.e.,

[0090]将一天的总运行时段划分为不同的时段,图中tl、t2、…、tq、......、tm分别表不一天中的各个时段,m为划分的时段总数。 [0090] The total number of day's total run period is divided into different time periods, FIG tl, t2, ..., tq, ......, tm, respectively, the table is not one day of each period, m is the division period. 吟表示tq时段的客流量占第V个〇d对一天内客流量Oidj 的比例,则〃 Λ,表示该第V个od对在tq时段的客流量。 Yin tq represents a period of traffic representing Comparative 〇d V th day Oidj traffic, then 〃 Lambda, indicating that the second pair of V od traffic in the period tq. 图2中,各阴影部分的底边长度表示0此,使阴影部分的底边相等,则各阴影部分的面积的变化情况反映了路网中od对oid j的客流的时段分布特征。 2, the length of the base of each of the hatched portion represents 0 Here, the hatched portion so that the bottom edge are equal, changes in the area of ​​the shaded portion of each period reflects the distribution of traffic on the road network od of oid j.

[0093] 步骤2:由初始化模块将初始客流发生量加载到路网中。 [0093] Step 2: The initialization module by the initial amount loaded into the traffic occurs in the road network. 该初始客流发生量是路网中一开始加载的客流总量,是一个历史同期统计数据的平均值。 The initial amount is the total passenger traffic occurred in the beginning of the road network load is the average of the same period a historical statistical data. 所述初始化模块0D将该初始客流发生量乘以所述od分布比例矩阵中的各个数值,得出的结果矩阵就是加载后的初始客流od分布矩阵,该初始客流od分布矩阵表示每个od对上的初始客流发生量。 The initialization module 0D the initial amount of traffic occurs multiplying each value of the distribution ratio od matrix, the matrix is ​​the result after the initial traffic loading od distribution matrix, the matrix representation of the initial traffic distribution od each pair od the initial amount of traffic on the occurrence.

[0094] 步骤3:在仿真模块中开始仿真,在该模块中,运用计算机仿真技术,模拟乘客实际出行的情况,每位乘客按照其出行特征在仿真系统中从〇到(1出行,该出行特征是指该乘客出行的起始点〇、终到点d以及所选择的路径。并且,通过计算机仿真可充分模拟行人在城市轨道交通系统中的出行情况,包括行人的出行需求、出行〇d、出行路径选择行为等。对客流的时间和空间特征进行了很好的刻画。工作日和节假日的客流出行需求不同,在该客流出行的基础上,路网的运输能力也不相同。 [0094] Step 3: Start simulation simulation module in the module, the use of computer simulation technology, simulate actual passenger travel, wherein each passenger in accordance with its travel from the square to the simulation system (1 travel, the travel characterized in that the means square passenger travel start point, end point d, and the selected path. Then, the computer simulation pedestrian travel case sufficiently simulate urban mass transit systems, including pedestrian travel demand, travel 〇d, travel route choice behavior. temporal and spatial characteristics of the passenger had a very good characterization. different working days and holidays of passenger travel demand, on the basis of the passenger traveling on the road network transport capacity is not the same.

[0095] 步骤4、由服务水平计算模块计算并输出各线路及各车站的服务水平。 [0095] Step 4, the service level is calculated by the calculation module and the output of each line and each level of service stations.

[0096] 对于一条给定线路,其各个区间在一天内各个时段运输的乘客数量不同,因此其满载率在线路各个区间的各个时段也不相同,为了计算线路一天内的平均满载率,应该先计算线路各个区间在一天内各个时段的满载率平均值,再据此计算该线路在一天内的满载率平均值。 [0096] For a given line, which is different each day interval each period the number of passengers transported, so the full rate is not the same in each time interval of each line, in order to calculate the average load factor in the line day should first load factor calculating circuit for each section in each period of the average day, then the load factor calculated accordingly the average line of the day. 为求得满载率的各个平均值,可采用加权平均的方法。 To obtain respective average values ​​for the full rate, a weighted average method may be employed.

[0097] 假设某条线路上车站总数为n,则线路上区间数为n-1,可用1^1^13…Ivln-Kl <k<n_l)表示线路上的各个区间。 [0097] Suppose the total number of stations on a route is n, the number of the line interval n-1, available 1 ^ 1 ^ 13 ... Ivln-Kl <k <n_l) represents each section on the line. 各个区间的满载率的值一天内各个时间段是不同的,时间段的划分也可以不固定,不同的区间可以有不同的时间段划分。 The value of the load factor of each of the day sections are different each time period, the time period may be divided not fixed, different sections may have different time division. 因为各个区间的满载率变化情况不一定相同,例如,区间A的早高峰是7点到8点,而区间B的早高峰是7点半到8点半。 Because the change of load factor for each section are not necessarily the same as the case of, e.g., early peak interval A is 7:00 to 8:00, the morning peak period B is 7:30 to 8:30. 比如对于区间Ik,将其一天内的运行分为t个时间段,可根据其满载率的值在一天内的变化情况确定某一时段s的满载率权重,则区间I k在一天内的满载率加权平均值为: For example, section Ik, one will run within the time period t is divided into, can be determined by a full period of the right s weight, the interval I k in the day in accordance with the value of its load factor varies within a full day rate weighted average of:

[0098] [0098]

Figure CN103279669BD00101

[0099]式中,lfk即为区间Ik在一天内的满载率加权平均值,Ps为区间Ik在第s个时段内列车的乘客总人数,cs区间Ik在第s个时段内列车的总定员人数。 [0099] In the formula, LFK interval Ik is the load factor in the weighted average of the day, the total capacity is the total number of passengers Ps interval Ik in the s-th period of the train, the train CS interval Ik in the s-th period number.

[0100]确定了区间Ik在一天内的满载率加权平均值后,再根据各个区间的lfk值,确定各个区间的平均满载率在整条线路中所占的权重(该权重可以通过例如专家打分法确定),假设区间Ik的lfk值在线路上所占的权重为wk,则线路在一天内的满载率加权平均值为: After the [0100] determined interval Ik load factor weighted average of the day, then according lfk value of each interval, to determine the weighted average load factor of each segment is occupied in the entire line of the weight (the weight can be, for example, expert marking determination method), the value assumed lfk interval Ik of the line occupied by the right weight wk, the line load factor in the weighted average of the day:

[0101] [0101]

Figure CN103279669BD00111

[0102] lline的值即可反映该线路一天内满载率的平均值。 [0102] lline value to reflect the average of the day the full line rate. llin4^值越大,即线路平均满载率越大,则车厢内的乘客越拥挤,线路的服务水平也越差;反之,线路的服务水平越好。 llin4 ^ larger the value, i.e., the larger the average line load factor, the passengers inside the congestion, the worse service line; the contrary, the better the service line.

[0103] 所述车站服务水平可以用两个指标来衡量,分别为站台容纳能力利用率α和乘客集散时间动态系数β,如下式所示: [0103] The service station can use two indicators to measure, respectively, the platform and a passenger carrying capacity utilization α distribution time the dynamic factor beta], the following formula:

[0106] 其中,parerage3为站台平均乘客密度,pmax为最大站台乘客密度,Tave3rag(3为平均乘客集散时间,Tfr%为乘客自由走行时的集散时间。该集散时间是指乘客从进站闸机处进站到上车,以及从下车到出站闸机处出站时所花费的时间。 [0106] wherein, parerage3 average passenger density for the platform, pmax is the maximum density passenger platform, Tave3rag (3 times the average passenger distribution, Tfr% for passengers consisting of rows down time distribution. The distribution time is the time from the stop gates passenger to stop the car, and at the time when the outbound station gates takes to get off from the.

[0107] 步骤5、由终止条件判断模块判断所述服务水平是否满足计算终止条件,若满足, 则执行步骤7,若不满足,则执行步骤6。 [0107] Step 5, the termination condition determining module determines that the service level is calculated satisfies the termination condition, if yes, step 7 is performed, if not satisfied, step 6 is performed.

[0108] 步骤6、由压力增加模块向路网中增加增量客流(用△0表示),然后执行步骤3。 [0108] Step 6, the incremental increase in pressure increases the passenger module (represented by △ 0) to the road network, and the step 3. [0109]步骤7、由显示模块显示所述当前总客流量,仿真计算结束。 [0109] Step 7, by the display module displays the current total traffic, the end of the simulation.

[0110] 所述终止条件包括线路服务水平合格率超过第一预设比例以及车站服务水平合格率超过第二预设比例。 [0110] The service termination condition includes a line passing rate exceeds a first predetermined ratio and the yield of the level of service station exceeds a second predetermined ratio. 所述服务水平是否合格与用户所指定的服务水平标准等级有关。 The service level eligibility related to user-specified level of service standard levels.

[0118] 在本发明中,比如用户指定了线路服务水平标准等级和车站服务水平标准等级都为B级,则合格的线路服务水平和车站服务水平应达到B级或以下。 [0118] In the present invention, such as the user specifies a service level standard line level and standard grade service stations are class B, the acceptable level of service lines and service level should reach the station class B or less.

[0119] 所述线路服务水平合格率用γ L表示,为: [0119] The yield of the horizontal line service is represented by γ L, as:

[0123] 其中,nL为路网中线路服务水平达到B级及其以下等级的线路条数,Nl为路网中的线路总条数;ns为路网中车站服务水平达到B级及其以下等级的线路条数的车站数量,N s为路网中的车站总数量。 [0123] wherein, nL level reaches level B and below the number of lines of road network service line, Nl is the total number of lines in the road network; NS service station for the road network and the levels of grade B the number of the station number of pieces of level lines, N s is the total road network station number.

[0124] 比如,第一预设比例和第二预设比例都为80%,则所述终止条件为: [0124] For example, the first predetermined ratio and the second predetermined proportion is 80%, then the termination condition is:

[0125] γ l>80%&& γ s>80% [0125] γ l> 80% && γ s> 80%

[0126] 在步骤5中,判断线路服务水平和车站服务水平是否满足上述终止条件,如果满足,则执行步骤7,显示所述当前总客流量,仿真计算结束。 [0126] In step 5, the line is determined service level and the service level of the station satisfies the termination condition is whether, if so, step 7 is performed, the end of the current total traffic display, simulation. 若不满足,则执行步骤6,向路网中增加增量客流,继续执行步骤3。 Not satisfied, step 6 is performed, the incremental increase passenger road network, proceed to Step 3.

[0127]步骤6中的增量客流体现了压力测试的思想。 Increment in [0127] Step 6 passenger embodies the idea of ​​stress tests. 压力测试一般多用于金融组织和计算机软件系统,在本发明中该思想原理在于:将轨道交通路网看作一个压力测试对象,将加载的增量客流作为压力,通过不断增加压力以测试该路网的最大承载能力,当路网达到承载能力的边缘(即终止条件)时,不能再增加压力,则此时的压力总量即当前客流总量就为该路网的运输能力。 Generally used for stress testing financial organizations and computer software systems, in the present invention is that the idea of ​​principle: the rail transit network as a stress test object, load increments as passenger traffic pressure by increasing the pressure to test the road the maximum carrying capacity of the network, when the road network reached the edge of the carrying capacity (i.e. termination condition), the pressure can not be increased, i.e., the total pressure at this time is the total amount of the current transport capacity for the passenger on the road network.

[0128] 具体地,首先按照od分布比例矩阵中的各数值(^,(^,(^,…,(^,…,分别将增量A0分配到各〇d对上,即第v个od对的增量客流为ω ν · Δ0。 [0128] Specifically, first by the numerical distribution ratio od matrix (^ (^ (^, ..., (^, ..., A0 respectively assigned to each increment 〇d pair, i.e., the v-th od incremental passenger traffic to ω ν · Δ0.

[0129] 进一步地,根据各od对上客流时空分布的差异,可以将增量客流进一步分配到各〇d对一天内不同的时间段上。 [0129] Further, according to the differences of the temporal and spatial distribution od of the passenger, the passenger can be further incremental 〇d assigned to each of the different time periods within a day. 例如,第v个od对表示从西直门站一阜成门站,则其增量客流为ω v ·△ Ο,一天内可将其分为比如7个时间段,每个时间段的客流量占该od对总量的比例为奶、奶、奶、咚、灼、科,、卿? For example, the v-th of od represents a XIZHIMEN from Fuchengmen station, the passenger flow increments ω v · △ Ο, the day can be divided into seven time periods, such as, traffic accounting per time period the od of the proportion of the total for the milk, milk, milk, boom, burning, Branch ,, State? 则每个时段的发生量分别为i;;t · · φ] , ω *ΑΟ·φ, 、 ω, ·Μ)·φ·. ν ωγ ·Α0· (p_, , ύ)γ * W · φ= > (0,. · · φ( , · ι/λ 〇 The generation amount for each period were i ;; t · · φ], ω * ΑΟ · φ,, ω, · Μ) · φ ·.

[0130]步骤7中的当前总客流量是指最后算法结束时候,路网中的总人数,即初始客流发生量和所有增量客流的加和。 The [0130] Step 7 refers to the current total traffic last algorithm ends when the total number of road network, ie, the initial amount of traffic occur and all incremental and passenger plus. 下面通过本发明的方法和系统来计算以下条件中的路网运输能力: The following transport capacity of the road network is calculated in the following conditions by the methods and systems of the present invention:
