Abstract: Analyzed of GPSR routing algorithms in networks, and applied it to path selection algorithm of traffic guidance system. Then improved it combined with the road congestion information, introduce congestion distance factor, saving travel time.

Abstract: This paper focuses on the high transportation costs problem of the finished vehicle existing in the current vehicle logistics industry, which results from the inappropriate choice of the transport mode. Firstly, we establish a 0-1 programming model to select the integrated transportation mode quantitatively; Secondly, we solve the model by searching method which based on time constraint and capacity constraints; Finally, a case about the selection and optimization of the finished vehicles’ transportation mode in Anji Automotive Logistics Co.,Ltd are introduced to verify the model. The case results indicate that in the premise of meeting the requirement of time, the integrated transportation can greatly reduce the total transportation costs, which have significant implications for future reference in the choice of finished vehicle transportation.

Abstract: A road traffic flow detection system is designed based on induction loop, and the control platform is constructed based on the most advanced 32-bit ARM processor and CPLD. The systems hardware framework and software design process are introduced in this paper. The defects of traditional system such as deficient processing capacity and low measurement accuracy are overcome. In this system the data of the frequency change caused by the vehicles through the coil is collected, and the function of vehicles type classification in real-time is added, which is a great improvement compared to traditional induction loop detection system of vehicles.

Abstract: With the rapid development of social economy, China has sped up urbanization and motorization, as thus the intercity rail transport has become an important means to solve the traffic inconvenience. Traffic distribution forecasting is the second stage of Four-Stage Predict Method. To make the trip distribution forecasting fully reflect the impact of socioeconomic and land use, this paper builds a generalized cost calculation model by fitting the areas based on cluster analysis, and the generalized cost is applied to Gravity Model as traffic impedance, which improves the forecast accuracy to some extent. Finally, taking Nanchang-Jiujiang intercity railway as the empirical analysis sample, the result obtained shows the practicality and simplicity of the method.

Abstract: This article will focus on the study of the dynamic dead reckoning algorithm .Dead reckoning technology is the basis for high- traffic and high -density complex airspace management , air traffic is an important component of automated decision-making system . In airspace management , all of the traffic management strategies can be generated by the aircraft 's forecast track . Depending on the precise spatial location and route on expected over time , dead reckoning implementation will significantly reduce the uncertainty in the future of aircraft flight paths , which makes the airspace and airport resources are efficiently used , the safety of an aircraft in the airspace the problem is further protection.

Abstract: As an important part of Advanced Driver Assistance System (ADAS), the traffic sign detection has been paid more and more attention. This paper studied and implemented a valid algorithm of traffic sign detection. Using K-means clustering algorithm to complete the image separation and extraction of prohibition signs from the RGB color image, and then matching them with templates to realize the detection of traffic signs by SIFT algorithm. Series of experiments for traffic sign detection have been carried out to prove the validity and correctness of the algorithm on the basis of the road images in front of the vehicle collected by CCD camera.

Abstract: To make the play time of visitors are fully rational arrangement and according to the current phenomenon of wasting paper tickets of amusement park, this paper combined with concepts and technologies of cutting-edge ubiquitous network and Internet of things, used the two-dimensional code which is widely used, innovatively proposed the concept of intelligent queuing, two-dimensional code electronic tickets and designed the intelligent management system of amusement park based on two-dimensional code. The design of the system is based on B/S structure as well as the MVC design pattern. This paper analyzed the innovation of the system, described the key technologies and given the realization ways.

Abstract: This paper presents a design campus online supermarket management system based on the B/S structure, using Microsoft's ASP.NET 4.0 dynamic website technology and SQL Server 2010 backend database for the application to achieve the basic function of campus online supermarket management system.

Abstract: This paper introduces the methods and steps of the development of Android mobile game based on App Inventor2 development environment which is completely based on cloud computing server online development, and through in detail how to use App Inventor2 development tools to abandon the traditional complex programming method which needs to write a lot of source code, and how to use Lego blocks of simple programming method to realize the fast Android mobile game development .This method can make without the basis of programming beginners can easily build your own Android applications.

Abstract: A new automatic text summarization based on discourse structure of Chinese is proposed and build a summarization system. System has 3 steps: first, generates contributing the text physical structure tree; after that, it analyses the content of original texts by fusing the complex sentence, RST and many characteristic of the language, and gives RST and complex sentence analysis algorithm, then it has the logistic relation between the each level of the text and the logistic structure; finally, using the rule of the ambiguity is applied to improve the fluency of the summary last. The evaluation results of the system are satisfied.
