Abstract: In this paper, we use the waterway freight volume and the actual statistical data of completed amount of fixed investment to model the prediction of waterway freight volume, to introduce tolerance error value into the collected data, and to evaluate the uncertainty of the model by using rough neural network. Finally, by comparatively analyzing the deviation of the predicted data and the ideal data, we proved the feasibility of rough neural network in the uncertainty analysis of waterway freight volume forecast model.

Abstract: Configuration of handling equipment in railway container terminal during operation is vital for improving economic performance and raising competitiveness. Aiming at reasonable investment of handling equipment in railway container terminal, Binomial probability is built analyzing relationship between owned equipment, equipment attendance number and serviceability rate. Equipment dispatching assurance rate is discussed. A case is studied to testify the model. In the case, a table of probability distribution of the number of the equipment used is listed to achieve the best number for attendance equipment, the number of owned handling equipment with different serviceability rate and best equipment attendance number is tabulated for searching the best equipment attendance number. The result is operable.

Abstract: This paper from the network level design the urban rail transit passenger transport microcosmic simulation model. Take the model’s achieve and apply as a target, through analyse the simulation model’s class library and its properties, design the event driven model, optimize the model frame and etc work, develop the urban rail transit passenger transport microcosmic simulation system, and through the Suzhou Rail transit planning network’s calculation example, verified the system’s availability.

Abstract: Through analyzing the development of the present situation and planning of highways of Chongqing, this paper indicated that the becoming of the country's urban and rural comprehensive reform pilot area, the urban transportation planning, the urban logistics planning, the industry development planning and the conformation of economic circle of Chengdu-Chongqing are the main driving force for Chongqing to develop its highways. This paper also proposed some countermeasures and suggestions of large-scale construction of highways on construction funds, road plan,road maintenance as well as demolition resettlement for Chongqing.

Abstract: By incorporating a cumulative distribution function of the maximum permissible purchasing price, a discrete time dynamic pricing model is developed in which the high-speed railway can set its prices at the time of booking request arrivals. The dynamic pricing policy included suitable price for the opened booking classes with respect to different combination of booking statues and remaining planning time, and when to close those opened booking classes.

Abstract: The factors affecting the maritime accidents are complicated. Digging up the factors and finding out the inherent laws,maritime accidents can be forecast in a short-term and medium-and-long-term.The paper analyzes the factors and discusses the BP neural network modeling process of maritime accidents based on influence factors. Through the validation, the forecast model of maritime accidents is feasible.

Abstract: The research of high-speed railway running economic benefit is important to timely know well the train operation state for the railway administration. A prediction model of high-speed railway running economic benefit is proposed in this article based on Gray model. The Gray model is a good example to make accurate prediction of the development of matters. According to the data analysis of Beijing and Shanghai railway stations, we can know that the result of prediction model is accurate, so the prediction based on Gray model is scientific and reasonable in the practical application.

Abstract: Investment in transportation infrastructure is bound to promote the economic development . Coordinated development of transport and economy is the best state. This paper discusses the principle of coordinated development between traffic and economy, build evaluation index system of transport and economy development, use entropy weight method to calculate the composite score, draw traffic - economy coordination degree model. Then set Huanggang City of Hubei province example to illustrate the usefulness of the model.

Abstract: A model based on carbon emissions is established to guide vehicle behavior at signalized intersections. This model takes working conditions and emission characteristics of vehicles into account, uses VT-Micro model exploited by Oak Ridge National Laboratory to calculate emissions, and provides vehicles with the lowest-emission working plan to drive through intersections. This model is able to reducing carbon emissions at the source and it agrees with the development of low-carbon transportation.

Abstract: With the growth of population and vehicles, transportation sector is taking up the major share of energy consumption and CO₂ emission in BRIC Countries. This paper is intended to analyze the energy, emission and environmental situation of the transportation sector in BRIC Countries from an energy point of view. Historical data is used to investigate the energy consumption in BRIC Countries from 1990 to 2009. A method of calculating CO2 emissions is employed in transportation sector of BRIC Countries. The total CO₂ emission and emission from sub-sector of transportation in CO₂ emissions of the four countries are described. The polices to reduce energy consumption and emissions are suggested to give a richer understanding of current status in transportation environment of BRIC Countries
