Authors: Zhu Nuo
Published: January 2014

A improved dynamic parameters model is presented based on cellular automata in this paper.The dynamic parameters: Direction-parameter, Empty-parameter and Cognition-parameter are formulated to simplify tactically the decision-making process of pedestrians, which can reflect the pedestrian judgment on the surrounding conditions and decide the pedestrians choice of action. Simulation of pedestrian evacuation and pedestrian moving rules were established, according to two-dimensional cellular automaton Moore neighborhood. In the improved model, the impact of the pedestrian density around exits is considered, the simulation and experimental results prove that this improvement makes sense, because besides the spatial distance to exits, people may also choose the exit according to the pedestrian density around exits. And the simulation results of improved model is compared with experiment, comparison shows that the improved model can reproduce the experiment well. The improved model is useful for further study, it is instructional significant for pedestrian evacuation, avoiding or reducing the number injuries.

Published: January 2014

The parking of vehicles in inhabited areas is a problem of majority of town with developed road traffic. The deficiency of parking place especially in town centers causes a lot of conflicts which influence the traffic flow continuity and traffic safety. Newly established parking places are usually occupied in short time and the problem is repeated. Trying to locate a lot of parking places on limited space of urban road results in various conflict situations when the vehicles parked along the road (lengthwise, perpendicularly or at angle) reach the roadway, the drivers enter the running lane during getting out of a vehicle or getting in a vehicle, etc. The paper presented brings results of analysis of conflict situations from such urban road with parking places along the road with use of video analysis. There are also presented designs for solutions of these problems with the purpose to increase the safety of all road participants.

Published: January 2014

Integration is not only the main content of development of urban passenger transport system, but also the urgent need to raise the level of public transport services and enhance the attractiveness of public transport. Thus coordination of urban rail transit and conventional bus transit systems is an inherent requirement of implementation of public transport priority development strategy. In the context of rapid development of rail transit in domestic cities, after summarizing the theory and practice of integration of urban rail and conventional bus transit, this paper analyzed the meanings and levels as well as the evaluation method of coordination between urban rail system and conventional bus system. On the basis of analysis, the evaluation indexes of coordination between urban rail system and bus system from institutional, technological and economic views are defined. After that, an evaluation index system of integration level of urban rail network and conventional bus network was set up.

Urban public transportation is the main effective way to solve the problem of increasingly congested city ground traffic, and public transport priority is the important guarantee to realize the way. Due to the short domestic history, there are problems to be solved in the respects of on the implementation of "public transport priority" in specific operation method, implementation measures and matters needing attention etc. Some oversea cities with high population density and serious traffic congestion have made some exploration in public transport priority development whose experiences are worthy of reference. Tokyo, the typical oversea city, has been selected out by this paper. Analysis has been down on the issue of the experiences and achievement of Tokyo in implementing the public transport priority strategy which is donated by urban rail transit, and experiences are summed up. On the basis of it, some suggestions have been proposed for the implementation of China's large cities public transport priority strategy.

This paper deals with the optimization problem of motor train-set in dedicated passenger line, a motor train-set operational model was proposed and maintenance constraint was considered . To solve this model and utilize the motor train-set efficiently, we described a two-step method and the problem was divided into two sub-problems: one is to make sub-routings and another is to combine these sub-routings to new circulations. First step the Hungarian algorithm was used to get circulations of the motor train-set without considering maintenance constraint and the circulations will be divided into several sub-routings by the constraint of maintenance. In order to utilize the motor train-set more balanced, the second step is to combine these sub-routing to new circulations by path exchange rules. This approach was evaluated on the Jing-Hu Passenger Dedicated Line, the computational results show that this new method is feasible and we provide a new idea to solve such problems.

In our country, the quantity of non-motorized vehicle are huge, non-motorized vehicles lanes set conditions give a great affect on the utilization of non-motorized vehicles lane, therefore it is necessary to study the relationship between the utilization of non-motorized vehicles lane and various factors affecting, and build relationships model. This article mainly collection a large number of situation non-motorized transport data, and build relationship model between non-motorized vehicles lanes utilization and Factors influencing for some non-motorized vehicles lane based on the analysis of the data, and then validate the model. Studies show that: non-motorized vehicles lanes traffic rate and non-motorized lanes utilization has no correlation; non-motorized vehicles lanes width and non-motorized vehicles lanes utilization comply logarithmic correlation model; non-motorized vehicles lanes traffic density and non-motorized vehicles lanes utilization comply linear correlation model.

Urban public transport is the main means of urban resident trip. With the rapid development of national economy, the city size is expanding, and the urban population is becoming larger and larger. However, the development of urban transportation doesnt keep up the pace of development of socio-economic. Traffic jam has become a problem to be urgent solved to some cities. This article selects No.23 bus line in Huaian as studying object, analyzes characteristics of resident trip in Huaian, By referencing the minimum total system cost model, which aims at minimizing the total passenger travel time costs and operating costs, to optimize station distance of No.23 bus line, so can improve bus running efficiency, meet the travel needs of residents better.

Along with the rapid growth of world trade, new requirement for throughput efficiency of modern container port are put forward. The existing optimization method to research the transport of the container terminal is single and complex. So in this article, the quantitative integrated optimization of the quay cranes and the trucks is made and the research scale is enlarge, in order to improve the efficiency of the research results. A model is built based on queuing network theory, and the mathematical algorithm is used to solve the model. Some experiments are used to demonstrate the feasibility and effectiveness of this study. The result shows that developed a genetic algorithm get the most optimal ratio of resource, and through a series of numerical examples . Are given The method to match the quay cranes and the trucks at container port logistics system, obtained by the techniques and algorithms in this study, can improvs the comprehensive efficiency of container ports.

Logistics has become an important part of growth in China. The rapid logistics industrial development could be attributed to the industrial agglomeration in the country. Panel data methods are used to analyze the factors influencing the logistics industry agglomeration. In the model, location quotient is considered as a dependent variable. Per Capita Gross Regional Product, Freight Traffic in Railways, Freight Traffic in Highways, Average Wage of Employed Persons in Transport, Storage and Post, Gross Regional Product in Wholesale and Retail Trades are selected as independent variables. Location quotient of the 31 provinces in China was calculated, and then obtained the fixed effects model. The results show that these five factors can affect logistics industry agglomeration both negative and positive effects. The Freight Traffic in Railways and Average Wage of Employed Persons in Transport, Storage and Post are negatively related to agglomeration degree, while the others are contrary.
