However, from 3 dimensional point of view, it is far away from the fact that the effect is come from many points along the rail while the trains move through rapidly. Two-step is defined to simulate environmental vibration. In the first step, the train-track system is simplified as a series of subsystems. Taking into account the track power irregularity, each subgrade reaction under ballast block was calculated when trains move on the track. All the forces constitute point source array to simulate the source. In the second step, the foundation is simulated as isotropic layered media, combined with artificial boundary conditions in the calculation border region, using the decoupling finite element method to calculate the surface environmental vibration. The simulation result was compared with those from field observation in Beijing, China. The result is quite close to the field observation data, and provides a good foundation for further study on environmental vibration impact to buildings and human beings.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129161338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Secondly, the paper considers the impact on the multiindex decision, establishes the standard index decision-making matrix and positive-negative ideal solution decision-making matrix, and researches the analyzing model for transport network optimization which takes the objective functions as set of indexes and alternatives as set of domain by quantitative analysis according to the TOPSIS. According to the cumulative prospect theory and gray relational analysis, the prospect value function is defined, an optimization model is built, the optimum weight vector is solved, and the order of the program is determined. Finally, the example shows that this method can adjust the public transport network better, and the result was much more reasonable and practical.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132655629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper, basing on user equilibrium theory, studies the interaction between the traffic flow of private cars and that of buses in super-network, gets the optimize the traffic flows of the two transportation modes above when choosing different location of transportation terminal in city, and makes the bus-sharing ratio to maximize. Meanwhile, basing on getting the traffic flow of private cars and buses, the paper considers that the total travel cost in urban transportation network is made up three parts, which are the travel cost of private cars and the travel cost of buses, combines the total travel cost with the land cost of transportation terminal and the passenger transfer cost, and then constructs two-tier location model that bases on the ultimate goal that the total travel cost and land cost all achieve optimization.

How to improve the capacity of the intersection means very important. Traffic simulation is an effective way to solve traffic problems. It utilizes modern computer technology to realize practical traffic system specialty, analyzes traffic system’s probable action in sorts of limited condition. In this paper, regarding Nanshaomen intersection as studying target, the existing problems in present intersection are found and the reasonable signal timing scheme and traffic lane divider scheme in intersection are put forward with the help of VISSIM, on the basis of investigation the present traffic quantity in peak time, signal timing scheme and traffic lane function divider. The improved scheme is evaluated on motor vehicles travel time, speed, line up length. The result indicates the scheme can reduce the vehicle delay and improve the capacity of the intersection effectively, and the application of VISSIM in the intersection at grade of urban road can get to good effect. It provides the effective reference to solve increasingly serious traffic jam in the intersection at grade of urban road.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123085290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
