  • The Efficiency Measurement of Coastal Container Terminals in China
    • Abstract: Publication date: October 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 5
      Author(s): Dan LI , Weixin LUAN , Feng PIAN
      Following the implementation of the twelfth consecutive Five-Year Plan, the development pattern of coastal container ports in China has been shifted, which requires higher port efficiency and an improved development mode. The three-stage DEA (Data Envelopment Analysis) model is applied on the basis of input-output cross-sectional data of 42 coastal container terminals in China. The model statistically evaluates the comprehensive efficiency, the pure technical efficiency and the scale efficiency of coastal container terminals. The outcome shows that the efficiency of coastal container terminals is rather low in China, and scale inefficiency is the primary reason. There is a big difference in terminal efficiency of different port groups. The terminal efficiency of Yangtze River Delta and Bohai Rim is relatively high, but Southeast Coast and Pearl River Delta's is comparatively low. Furthermore, there is an excessive waste in the input of container terminal development in China. In the final section, suggestions are proposed for the existing problems in port developments.

  • Monitoring the Evolution of Traffic on Main City Roads
    • Abstract: Publication date: October 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 5
      Author(s): Jinli GONG , Xianwu PENG
      In order to monitor the evolution of traffic on main city roads, a fixed-point data monitoring system is devised. Firstly, after qualitative traffic data (flow, speed, and occupancy) are acquired, they are then translated into the traffic qualitative state (congested or uncongested) by Fuzzy C-means Clustering algorithm. Secondly, the Congestion Evolution Index is determined using Rescaled Range Analysis of data mining. Finally, by taking a sequence pattern similarity measurement and applying condensed hierarchical clustering methods, the routine pattern is distinguished. Consequently, real-time outlier detection is realized by a distance-based outlier detection algorithm. This algorithm was successfully applied based on 11 days of fixed-point data on the eastern segment of the Shanghai North-South expressway, it is concluded that the outliers distributed in 12:10-13:20, 13:40-14:30 and 17:10-17:15 on September 30.

    • Abstract: Publication date: October 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 5
      Author(s): Jarboui SAMI , Forget PASCAL , Boujelbene YOUNES
      The objectives of this paper are to measure the technical efficiency of 64 public road transport operators in 18 countries and to investigate the degree to which various factors influence efficiency levels in these firms. Stochastic frontier analysis (SFA) methods are applied to the sample over a twelve year period from 2000 to 2011. The empirical results indicate that operating profit, investment and firm size have a significant influence on technical efficiency levels. Conclusions indicate that technical efficiency level of public road transport operators varies between 0.46 and 0.95. Observations can be made that large-size operators with more investment capacity tend to be more technically efficient than small-size operators. Finally, the results concluded that operators from developed countries are technically more efficient than those of developing countries.

  • Route Selection for Railway Passengers: A Multi-objective Model and
           Optimization Algorithm
    • Abstract: Publication date: October 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 5
      Author(s): Xinfeng YANG , Lanfen LIU , Yinzhen LI , Ruichun HE
      With an increased operating speed in Chinese railways in recent years, the number of passengers traveling by trains has been significantly increasing. The research issue is regarding how passengers select their routes when there are no direct trains. Previous studies have dealt with the route selection problem as a multi-objective optimization. The study began by setting up a transportation network which encompasses the departure and terminal stations along with important intermediate stations. Then, six key factors are analyzed and formulated using a multi-objective model, consisting of the train-running time, railway fare, transfer frequencies, distances between transfer stations, transfer interval time, and travel comfort. Furthermore, a two-phase algorithm is employed to solve the model. A rapid searching algorithm for feasible routes based on the train timetable is established, then the weight vector is assigned by introducing the information entropy to obtain satisfied routes. In the end, the two-phase algorithm is tested respectively for railway passengers from Lanzhou to Beijing (with direct trains) and from Lanzhou to Changchun (without direct trains), and the results show that the proposed model and solution algorithm are efficient for obtaining satisfactory routes.

      To comprehend and evaluate the severity of traffic incident situations, an unconventional traffic management strategy should measure and calculate the severity of incident situations. This paper presents a freeway network traffic incident situation evaluation model by introducing the invulnerability concept in the complex network theory and perceiving the topological structure of a road network with the help of traffic incident situations. A case analysis was conducted for the invulnerability of a regional freeway network subsystem and the overall network. The model provides a solution for incident situation comprehension from the road network structure point of view.

  • Robust Transportation Network Design Modeling with Regret Value
    • Abstract: Publication date: October 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 5
      Author(s): Hui LIU , Chao YANG , Jun YANG
      Based on long-term transportation network design decisions and potential parameter variations, it is important that demand uncertainty is considered in transportation modeling. In this paper, we present a novel robustness measure that combines the two objectives by minimizing the expected travel time while bounding the relative regret in each scenario facing uncertain origin-destination demand (OD demand). The concept of α-robust solution is introduced into the transportation network design problem. We propose a robust transportation network design model with regret value constraints, then design an algorithm based on the genetic algorithm to solve the problem and obtain the optimal solutions for different regret values. Finally, numerical results based on the Nguyen-Dupuis network validate the effectiveness of the algorithm. While detailed analysis on trade-offs, between the expected travel time and the maximum regret value, shows that large reductions in maximum regret do not necessarily result in a great increase in expected travel time. Meanwhile, we compared the robust model presented with the stochastic model and numerical examples demonstrate that the robust planning network is more reliable and less risky than the stochastic model if demand uncertainty is considered in modeling.

  • A Dynamic Generalized Cost Based Logit Model for Passenger Corridors
    • Abstract: Publication date: August 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 4
      Author(s): Qipeng SUN , Lei ZHU , Bo CHEN
      In order to scientifically compute the supply allocation of various transportation modes for passenger corridors, a dynamic generalized transportation cost based Logit model is proposed according to the theory of random utility and discrete choice model. The model's robustness and accuracy were verified via MATLAB programming using the Zhengzhou-Xi'an Passenger Corridor as a study case. The analysis result indicates that transportation construction cost changes with the share, which is influenced by travel time and the random perception coefficient. Compared with existing models, the changes of sharing rate and that of transportation construction costs in this paper are not in the same direction. For the dynamic changing of generalized transportation costs, the sharing rate calculated only by a static travel time and ticket price is unreliable. The model proposed in this paper cannot only meet the individual demands of travelers, but can also keep the sustainable operation of transportation. The sharing rates calculated by the model for the Zhengzhou-Xi'an Passenger Corridor are more reasonable than those calculated by traditional models.

  • Estimating Smart Card Commuters Origin-Destination Distribution Based on
           APTS Data
    • Abstract: Publication date: August 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 4
      Author(s): Chen Jun , Yang Dongyuan
      Increasing the proportion of commuters travelling by public transportation can effectively ease urban traffic congestion. This paper addresses the application of Advanced Public Transportation Systems (APTS) data to analyze transit commuters travel demand. This study involved collection of APTS data and boarding stops information by combining smart card data and intelligent dispatching data. Transit commuters were judged according to travel frequency of morning and evening traffic peaks. The residences and work places were identified by spatial-temporal characteristics of commuters travel. Based on this idea, an estimation algorithm was proposed. The algorithm was tested and analyzed using large-scale APTS data. Finally, the method's accuracy was analyzed by comparison with the “Trip-chain” method. The proposed method provides some advantages including, high accuracy and strong operability. The study provides a fast and economic new approach to acquiring transit commuters Origin-Destination (OD) distribution.

  • OD Matrices Network Estimation from Link Counts by Neural Networks
    • Abstract: Publication date: August 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 4
      Author(s): Mussone LORENZO , Matteucci MATTEO
      This paper attempts to deal with traffic Origin Destination (OD) matrix estimation starting from the measurements of flow on road network links. It proposes a different approach from published articles to date, by applying multilayer feed-forward neural networks. Since the relationship between link flow and the related OD matrix is continuous, it is possible to use the well known approximation property of Neural Network models. The method is proposed for a real-time correction of the OD matrix. Two application scenarios were developed: a trial network and an actual rural network were both simulated by a micro-simulator that assigns known OD matrices. A Principal Component Analysis (PCA) technique was used to reduce the amount of variables and to achieve improved significance for input data. The estimated error was relatively low and, as opposed to analytical approaches, the processing time was almost in real time, making this approach suitable for applications in dynamic traffic management. Comparisons with results obtained by an OD estimation commercial program show better performance in the NN approach both as regards error and computing time.

      Investment risk evaluation of expressways plays a significant role in the sustainable development of expressways. A consideration of the inconsistency between operation accuracy and operation efficiency of the traditional quasi-3-layer BP neural network evaluation model is first established. This paper proposes and designs a variable-structure neural network model in the random re-linking process from the input layer neurons to the hidden layer neurons. Then, the model acquires the hidden layer to the output layer from the angle of structural optimization. Secondly, in view of the characteristics of the Chinese expressway investment, this paper develops an expressway project investment risk evaluation index system. Furthermore, a design of the expressway project investment risk evaluation model is completed based on the variable-structure neural network of the re-linking random process. In addition, the model has been verified with ten Chinese expressway projects. The risk evaluations have been conducted for four of the ten expressway projects. The research result shows that the average relative error predicted with such model is 1.91% and the maximum relative error is 2.63%. Therefore, the prediction result is deemed suitable.

  • A Paired Combinatorial Logit Route Choice Model with Probit-Based
           Equivalent Impedance
    • Abstract: Publication date: August 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 4
      Author(s): Jun LI , Xinjun LAI , Zhi YU
      An improved paired combinatorial Logit route choice model with Probit-based equivalent route impedance is proposed to simplify the calculation and resolve the homoscedasticity problem of the Logit model. The model comprises a two-level structure: the lower level employs a binary Probit choice model to address the problem of route overlapping. Clark's approximation for normal distribution is employed to compute the equivalent impendence for each route pair in the upper level. The homoscedasticity problem is resolved through the introduction of the normal distribution. The upper level is a classical multinomial Logit model with relative impedance that reduces the defect of variance-homogeneity in the upper level. The probability of route selection is determined by marginal and conditional probabilities. The proposed model combines the advantages of both Probit and Logit models with close-form formulations, which can be easily calculated. Two numerical tests, which were performed on the well-known examples, indicate that the proposed model produces more reasonable and stable results.

      Regional bus scheduling is the future trend in public transportation which deals with allocating trips belonged to several routes to buses located at different depots to reduce the size of bus fleets and their operating costs. Considering many emergency events which may affect on-time vehicle arrivals, a bi-level programming model is applied to address the relationship between bus scheduling and its procurement scheme from an overall perspective. The model takes into consideration several constraints such as depot capacities, fueling, and emissions of polluting gases. Solutions to different situations of the upper and lower model are obtained by using a genetic algorithm. Based on some established criteria for a satisfactory solution, a series of lower solutions meeting the established criteria are generated as inputs for the upper model. Thereby, the best lower and the corresponding upper solutions are generated by comparing them. Finally, an example is illustrated to prove the accuracy and effectiveness of our model and its algorithm.

      To identify the energy consumption driving factors and measure their corresponding contributions in energy consumption, the paper classifies the factors into scale effect, structure effect and technique effect according the driving mechanism. It then analyzes the correlations between these factors by ASIF data structural principles and the time series regression. The contributions of these factors are measured via the expanded LMDI decomposition model based on the LMDI method. The result indicate that: (1) the impacts from scale effect and technique effect are weakening, while that from structure effect is increasing; (2) the transport supply structure needs to be further optimized, and there exists plenty of space for reducing the impact on energy consumption; (3) the energy efficiency has increased a lot in recent years, but its contribution to energy consumption is shrinking. Improving the transport intensity exerts significant effect on saving energy. The reliability of the models and its conclusions is proved by empirical studies, which provides scientific supports for the policy making of regional low-carbon integrated transport.

      In order to develop a low-carbon emissions transportation system, it is important to study the carbon emissions reduction ability of transportation structure optimization. Based on analysis of the impact of transportation structure on carbon emissions, this paper employed a quantitative approach and time series data (1989–2009) to analyze the effect of transportation structure on carbon emissions in China. In this study, a quantitative approach of the decomposition analysis and the impulse response function were combined. Measurements of the quantity change in carbon emissions caused by the transportation structure factor were obtained along with the responses of the carbon emissions to the impulse of the transportation structure optimization. The relationship between transportation structure and carbon emissions was discussed based on empirical results, including: (1) short- and long-term influence of transportation structure on carbon emissions; (2) comparative analysis of transportation structure and other principal factors; (3) the dynamic interaction mechanism between transportation structure and carbon emissions. The outcome of this study proved to be valuable for researchers and decision makers in this field.

      The time-gap data have been modeled through non-composite distribution up to a flow level of 1,800 vph. It has been found that these models are not capable of modeling time gap data at higher flow levels. Some composite distributions have been proposed to overcome this problem. But, due to the fact that the calibration of model parameters used in composite distributions is tedious, there use may be relatively limited. In this paper, five mixture models namely Exponential+Extreme-value (EEV), Lognormal+Extreme-value (LEV), Weibull +Extreme-value (WEV), Weibull+Lognormal (WLN) and Exponential+ Lognormal (ELN) have been used to model time gap data for flows ranging from 1900 vph to 4100 vph. Two types of goodness-of-fit tests namely cumulative distribution function (CDF) based and two-sample (Cramer-von Mises test) & K-sample (Anderson-Darling test) based tests were performed. Among all the five models, Weibull+ Extreme Value was found to be the best mixture model for modeling time gap data as it performed consistently well in Cramer-von Mises test and K-sample Anderson-Darling test.

      Bus isochrones indicate the maximum scale of bus system can extend during one time interval. A calculation method of isochrones is proposed in this paper and it can be applied to the analysis of public transport accessibility. The travel process by bus is analyzed and divided into five parts: walking to the bus stop from departure, waiting for buses, boarding buses, transfer and walking to the destination. Specific calculation methods of time cost are proposed for each part, respectively. Then, the isochrones are by the grid method and the inverse distance weighting method. The bus GPS data of Guangzhou, China is used to draw the isochrones maps and to demonstrate the Tee mall. Furthermore, the space-time accessibility is measured in the covering area of a unit time isochrones and the accessibility differences of different directions are then analyzed through profiles.

      By utilizing the efficacy coefficient method, this study proposes a multi-criteria modeling approach for the reasonable pricing decision of intercity rail passenger transport. The proposed model aims at minimizing the average travel time and energy consumption per passenger-trip for an intercity rail passenger transport system. It is empirically confirmed that the variation of the ticket price imposes significant influence upon the transport ratios of different travel modes. It is proved that the average travel time per passenger-trip and the system energy consumption declines with the reduced fare. As for the operation of rail passenger transport system mentioned in the case study, if its fare is adjusted to 55.8 yuan/passenger-trip, the average travel time and energy consumption per passenger-trip decrease by 7.8% and 2.1%, respectively. This study is able to assist the sensible decision-making of ticket price, which can also effectively promote the operation efficiency and sustainability of an intercity rail transport system.

  • Competition Model of Container Road Transportation Market
    • Abstract: Publication date: June 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 3
      Author(s): Gang DONG
      Considering two major factors of truck transportation service and freight forwarding quote to the sensitive shipper, this study proposes a market competition model of container road transportation. The model involves more competitive truck operators and one freight forwarder and solves the game equilibrium through backward induction. The results indicate that with application of value-added service, truck operators receive lower profit due to burden cost of the upgrading service. However, the demand satisfaction of truck transportation market significantly increased, and the overall profit of truck operators and freight forwarder witnessed an increasing trend. Therefore, to motivate value-added service of truck operator, the reasonable benefit distribution mechanism needs to be established between truck operators and freight forwarder, which provides benefits for the healthy development of truck operator and container transportation chain.

      After a survey of 10 long-distance highway passenger transportation stations in Beijing, we found that 50% of the stations do not provide express services for small-size cargo. Passenger stations that provide such services have a low profit. The main reason is that there is no effective pricing method for small-size cargo express services. To address this issue, we first looked at the operating costs of all the parties involved in small-size cargo express services. According to the customers' freight transport demand function, we propose a model for determining the price of small-size cargo express services with an objective function of maximizing the starting station's revenue. Based on the model, necessary conditions are specified in order for passenger stations and companies to operate such businesses. Furthermore, a method of fitting the transportation demand function is provided based on actual operations and services. Finally, a numerical example is given to illustrate the application of the proposed pricing method for small-size cargo express services.

      This paper establishes an evaluation index system of coordinated relationship between urban rail transit and land use under TOD mode. The evaluation results and rank are generated by the improved DEA model. Different input/output indexes are standardized through further analysis of different indexes' slack variables and surplus variables. The influencing degrees of different index factors to the coordinated relationship are examined. The improved directions of DEA invalid decision making units (DMU) are also analyzed through the DEA projection theory, which provides an improved reference to the invalid DMU. A case of Allegheny country in U.S. is conducted to verify the evaluation method, and the results show that the evaluations match well with the real situations. It is an effective way to evaluate the coordinated relationship between urban rail transit and land use under TOD mode.

      To relieve worsening traffic congestion and protect the deteriorating environment, many cities in China start to operate rail transit lines. However, the expected modal shift will only occur if the rail transit system offers great advantages over road transport modes. To this end, designing efficient operational arrangement has far-reaching impacts not only on rail transit itself, but also on the overall urban transport system. Focusing on a crowded rail transit line, this paper aims to jointly optimize fare, frequency and number of carriages under advocated management objectives. Factors that enter into this joint optimization include negative externality arising from noise pollution, the adverse effect from in-vehicle crowding and positive externality from road congestion relief. To assess whether the rail transit line in a given corridor is priced efficiently and the service provision is appropriate, detailed numerical calculations are carried out for one representative Chinese city—Suzhou. A synthesis of theoretical and empirical analyses depicts: compared with profit optima, social welfare optima are characterized with lower fares, greater frequency, more number of carriages and higher ridership; the change from the current operational arrangement to social optimum would call for reducing fares, increasing frequency and adopting more carriages.

      In this paper, the desired speed variable is introduced into the ‘table of games’ and a new ‘table of games’ and corresponding traffic kinetic model are then formulated. The hybrid programming technique of VBA and MATLAB is used to develop the computational engine for the proposed model. The study focuses on the effect of desired speed on the speed-density curve. With one desired speed, the relationship between average speed and density is investigated under different road conditions and desired speeds. With multiple desired speeds, an investigation is carried out on the effect of the coefficient of variation on average speed, and the effect of percentage of low desired speed vehicles on average speed. An important factor influencing average speed is the variation of the desired speed. When density is low, traffic flow is in an individual flow pattern, and the average speed of the traffic flow is determined by the variation of the desired speed. When density is high, traffic flow is in a collective flow pattern, and the average speed is determined by density.

  • A Crew Scheduling with Chinese Meal Break Rules

      An efficient crew scheduling can significantly reduce the operational cost for transit enterprises. However, the crew scheduling problem, known to be NP-hard, is complicated by the fact that there are many restrictions on the shift generation. Moreover, there are some special requirements in China, for example, meal break is normally required to be taken during the conventional time ranges for lunch or dinner, which is called a Chinese meal break rule to distinguish from the western ones. It also makes the existing crew scheduling approaches encountering difficulties. On the basis of the “generate and select” approach to solve the crew scheduling problem, this paper proposes an approach to handling the Chinese meal break rule in the phase of “generate”. Taking advantages of the characteristics of Chinese meal break rule and problem domain knowledge, a heuristic-based approach is proposed to select some promising relief opportunities (ROs). A shift generation approach is then devised to generate a large set of potential shifts that satisfy the Chinese meal break rule. Experimental results from 12 groups of real-world problem instances demonstrate the success of the proposed approach, which can greatly reduce the number of potential shifts generated. Therefore, it is suggested that the proposed approach be used to solve the large scale crew scheduling problems with Chinese meal break rule.

  • Effect of Road Traffic Congestion on Aviation Passenger's Flight Choice
    • Abstract: Publication date: April 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 2
      Author(s): Di CHEN , Ning ZHANG , Jian LIU
      This paper investigates how passengers choose flight times in view of ground traffic congestion. The departure time choice model of aviation passengers is developed by extending Vickrey's bottleneck model. The conditions are determined for the existence of the user equilibrium in the model. Then, the range of the difference between the airfares is established while the number of aviation passengers choosing the same flight time remains unchanged at the user equilibrium. Moreover, the tendency of the total queuing time and the incremental airfare revenue is derived along with the difference between the airfares. The results show that the number of aviation passengers is jointly determined by the flight time and the bottleneck capacity for different schedules. Under the given passenger volume, the total queuing time (traffic congestion) can be reduced or the incremental airfare revenue can be increased by properly adjusting the airfares difference. Two numerical examples are presented to demonstrate the principle and its application.

      To investigate the complex dynamics for airlines' price competition, this paper proposes a price competition model of airlines with differentiation strategy and with the theory of bifurcation of dynamical systems. The existence and stability of equilibrium points of the model are discussed according to dynamic stability criteria. The complex dynamics of this model in different market parameters are shown though numerical simulation. The simulation results show that the speed of price adjustment has a significant impact on the stability of the model, while the speed of price adjustment is larger than critical value, and the phenomenon of bifurcation and chaos will appear on the dynamic system. Compared with the Nash equilibrium profits, all airlines' profits are decreased obviously when chaos is occurred. Differentiation has an important impact on airlines' price and profits, it's helpful to have more competition advantage that to keep and strengthen the differentiation advantage against the competitors.

  • GPS Dynamic Filter Algorithm Based on Lifting Wavelet Transformation
    • Abstract: February 2013
      Publication year: 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 1

      It is difficult to establish a precise mathematical model of dynamic filtering for vehicle GPS navigation with Kalman filtering. And the traditional wavelet transformation has some shortness in real-time processing. This paper proposes a GPS dynamic filter algorithm based on the lifting wavelet transformation (LWT). It first decomposes the vehicle GPS navigation signal with the LWT. Then, it detects, eliminates and corrects the signal's gross error at different LWT resolution levels with statistical 3srule and polynomial interpolation method. The signal's noise is de-noised at different LWT resolution levels with modulus square soft-threshold de-noising method. Finally, the algorithm realizes real-time dynamic filtering for the vehicle GPS navigation system through reconstructing the de-noised LWT coefficients. The simulation results show that the algorithm is more effective than the Kalman filter in positioning precision. Compared with the traditional wavelet transformation, the speed is doubled for dynamic filtering even though the proposed algorithm only has little advantages on the positioning accuracy. Therefore, the algorithm is available for vehicle GPS navigation system.

  • Timing Oversaturated Signals: What Can We Learn from Classic and
           State-of-the-Art Signal Control Models
    • Abstract: February 2013
      Publication year: 2013
      Source:Journal of Transportation Systems Engineering and Information Technology, Volume 13, Issue 1

      Many signalized intersections in the United States are operating in oversaturated conditions during the morning and afternoon peak hours. Unlike under-saturated intersections, for which many well-established theories and signal timing policies have been developed, consensus has not been reached with regard to the control philosophy and timing strategy of oversaturated signals. For an isolated intersection, a common belief is that timely and efficient allocation of green time among the intersection approaches is essential to optimize traffic flows. A couple of the studies in the past have resulted in reasonable control policies that could possibly be implemented. However, the advantages and limitations of these strategies remain unrealized due to a lack of effective evaluation. This paper conducts an in-depth investigation to the characteristics and applicability of the control policies through thorough examination of two typical groups of classical models. The performance of the classic models is then compared with the latest versions of TRANSYT-7F and Synchro, upon which guidelines are made for effectively implementing signal control polices for oversaturated intersections.

      This paper summarizes the research status of intercity train operating scheme. To precisely describe the interaction between passenger flow and operating scheme, it proposes assumptions of system closure, train type division, passenger flow dynamic assignment and selecting priority during the process of establishing model. Based on these, it describes relative variables and formulates the passenger flow dynamic assignment model to reflect the conversion process of different passenger types. Then it develops a multiple objective programming model considering maximum railway department revenue, the smallest passenger total expenditure and the maximum passenger demand. It also uses the genetic algorithm to solve the established multi-objective 0-1 integer programming model. Finally, a numerical example is provided to illustrate the effectiveness of this algorithm of model.
