Abstract: There are many problems in the urbanization of county regions such as towns on small-scale, urbanization of low level, lagging service facilities, weak development support, not strong county center, insufficient attractive force of towns, central villages not yet formed. Some specific methods and measures are proposed on construction of new urbanization in county regions, for example, exerting local advantages of resources and environment, strengthening the center, constructing professional towns and villages of characteristic, building towns and economic development zone, making innovative mechanisms, coordinating towns and villages, realizing informatization of every industry, sharing public services, establishing various professional cooperative organizations, industrial parks and production bases, strengthening trade and logistics links outside the region, improving the ecological environment, perfecting the land transfer market between towns and villages, which are specifically described with an example of Dawu county.

Abstract: This study is about the old neighborhoods renovation assessment and design with questions of five times adjustment for Yong Kang Project urban design. Old neighborhoods renovation assessment criteria are set up through compare with Green Community Assessment criteria to the adjusting problems. The indices are used in the planning of this project. The results verify the necessity and feasibility of old neighborhoods renovation design from low-carbon eco perspective.

Abstract: With the tendency towards diversity and personalization of tourism product supply and tourists’ demands, tourism spatial structure at regional scale becomes a hot research topic. The rationality of tourism spatial structure affects the soundness of the tourist destination and the degree of the sustainable development. To carry out the study on the spatial structure of regional tourism system and construct the optimal mode of overall regional tourism development can provide theory and decision support to promote the collaborative development of regional tourism. The article puts forward the general strategies for the integration of regional tourism resources by analyzing the condensation nucleus and spatial divergence of the distribution of the tourism resources in Jiangsu.

Abstract: Subway as a means of transport is becoming a new gallery space and the flow of culture. Subway public art space is undoubtedly scope to create a visual sense of place and the interior space of the subway culture is the most direct and effective artistic language. This article highlights the importance of urban culture proposed metro public art from space to strengthen workplace awareness, and combines with the ancient capital of Xi'an, as the newly opened subway public art wall case, which analysis on the development dimension of public art.

Abstract: By comparing research methods in the different disciplines of botany, military science and mathematics, in order to discover the phytocoenosium structure of urban green space, this paper induced a simple and practical method, which included four steps, i.e., quadrats selection, integrity indicators surveying, individual indicators surveying and type identification. This method applies to those research activities with less precision need and compact time.

Abstract: This paper uses vensim to establish a SD prediction model of transportation and social economy, the model considers passenger transport capacity, cargo capacity, population, GDP and other major factors. Base on data in nearly ten years, the prediction results verify S-T SD model is ture and effective,and get the time-node that the growth rate of passenger capacity satisfied the shortage of Passenger transport capacity in different sensitivity parameter A.

Abstract: The research presents a long-term forecast model based on the use of a back-propagation (BP) neural network. Firstly, a brief overview of the forecast models and BP neural network model is demonstrated. Then the improved BP model based on factor analysis (FA-BP) and algorithmfor solving the model are presented. At last, a numerical case study is shown.As the current statistic yearbook only provides the volume data of Jing-Hu corridor, the notion of economical relation intensityis applied to process the original data. The results show that FA-BP neural network is effective in forecast. The proposed model providesa reference in the forefront field of integrated regional transportation planning.

Abstract: Comprehensive terminal integrates different modes of transport and sharing rates of different traffic modes influence its planning greatly. To determine the sharing rates, it’s necessary to study mode choice probability of passengers. Based on the theory of disaggregate choice, with the survey of mode choices of passengers arriving by rail in Nanjing south railway station, this paper establishes multinomial logit (MNL) model and nest logit (NL) model, considering three types of modes of transport including the subway, regular bus, and taxi. Models are calibrated with SPSS and validated through statistical indicators. Therefore, important factors influencing choice are obtained. The accuracy test results of two kinds of models show that NL model has higher prediction accuracy, and can overcome the shortcomings of traditional logit model’s independent and irrelevant alternatives (IIA). Finally, this paper develops the sensitivity analysis using the NL upper model as an example, and gives the sensitivity physical meaning, namely the development level of taxi.

Abstract: On the basis of analyzing the model of C space network in Lanzhou, the small world characteristics were found. Combine the main idea of box counting method and weighted network merging mechanism, the evolution mechanism was put forward based on the self-similarity of the network, then the urban transportation network of Lanzhou is optimized by this method and optimization results are obtained.

Abstract: In order to improve the vehicle alone path finding way, put forward a kind of road navigation algorithm based on agent. First put forward the intelligent design method, and then the intelligent design is mapped to different kinds of the intelligent agents. And then expounds the function of operation control agent, agent, Lane agent and intersection agent needs to realize. Finally, based on these agents of the navigation algorithm is designed using Dijkstra algorithm.
