With the continuous progress of social civilization and the development of the times, the industrial economy and people's living conditions in various regions of China have changed with each passing day in recent years. Relevant state departments have also paid more attention to the transportation industry. As the core of economic development, urban transportation projects are more complex than those in township areas and have higher requirements for managers. With the improvement of people's quality of life, the modes of transportation have become diverse. To ensure that all parts of the city can be carried out in an orderly manner and provide people with more unobstructed transportation facilities, we should constantly keep up with the pace of development of the times and improve the urban traffic engineering management. In this paper, the author mainly analyzes the current situation of urban traffic engineering management, and puts forward a series of effective measures to promote the development of urban traffic management.

In China, the traditional taxi industry is conforming to the trend of the times, with taxi drivers working with e-hailing applications. This reform is of great significance, not only for the taxi industry, but also for the transportation industry, cities, and society as a whole. Our goal was to analyze the changes in driving behavior since taxi drivers joined e-hailing platforms. Therefore, this paper mined taxi trajectory data from Shanghai and compared the data of May 2015 with those of May 2017 to represent the before-app stage and the full-use stage, respectively. By extracting two-trip events (i.e., vacant trip and occupied trip) and two-spot events (i.e., pick-up spot and drop-off spot), taxi driving behavior changes were analyzed temporally, spatially, and efficiently. The results reveal that e-hailing applications mine more long-distance rides and new pick-up locations for drivers. Moreover, driver initiative have increased at night since using e-hailing applications. Furthermore, mobile payment facilities save time that would otherwise be taken sorting out change. Although e-hailing apps can help citizens get taxis faster, from the driver’s perspective, the apps do not reduce their cruising time. In general, e-hailing software reduces the unoccupied ratio of taxis and improves the operating ratio. Ultimately, new driving behaviors can increase the driver’s revenue. This work is meaningful for the formulation of reasonable traffic laws and for urban traffic decision-making.

Intersections are the most important regions in terms of urban traffic management. The intersection areas on the corridor should be analyzed together for consistency in traffic engineering. To do so, three intersections on the Vatan Street corridor in İstanbul, the most crowded city of Turkey, were examined. Various geometric and signal designs were performed for intersections and the most suitable corridor design was analyzed. The corridor designs were modeled with the PTV VISSIM microsimulation software. The most suitable corridor design was evaluated by using the results obtained from the microsimulation via analytical hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) from multi criteria decision analysis (MCDA) methods. The evaluation criteria in the study are vehicle delay, queue length, stopped delay, stops, travel time, vehicle safety, CO emission, fuel consumption, and construction cost. As a result, the current and the most suitable alternative corridors were compared according to the comparison parameters and up to 80% improvements were observed. Thus, some advantages were obtained in terms of energy, environment, time, and cost.

The Development Trend

With the continuous development of the times and the continuous progress of science and technology, intelligent robots, big data, artificial intelligence, and other technologies are gradually emerging in the construction industry. Building construction inevitably needs new blood to solve current problems under the tide of information age. Intelligent building has become a necessary way for building development. At present, in the field of intelligent construction, research and theory in various directions have developed to varying degrees. Through the analysis of existing theories, this paper sorts out the theoretical framework and core logic of intelligent construction, and looks forward to the development trend of intelligent construction in the future.

Urban road traffic spatio-temporal characters reflect how citizens move and how goods are transported, which is crucial for trip planning, traffic management, and urban design. Video surveillance camera plays an important role in intelligent transport systems (ITS) for recognizing license plate numbers. This paper proposes a spatio-temporal visualization method to discover urban road vehicle density, city-wide regional vehicle density, and hot routes using license plate number data recorded by video surveillance cameras. To improve the accuracy of the visualization effect, during data analysis and processing, this paper utilized Internet crawler technology and adopted an outlier detection algorithm based on the Dixon detection method. In the design of the visualization map, this paper established an urban road vehicle traffic index to intuitively and quantitatively reveal the traffic operation situation of the area. To verify the feasibility of the method, an experiment in Guiyang on data from road video surveillance camera system was conducted. Multiple urban traffic spatial and temporal characters are recognized concisely and efficiently from three visualization maps. The results show the satisfactory performance of the proposed framework in terms of visual analysis, which will facilitate traffic management and operation.

Dunhuang frescoes carry the essence of millennia of civilization and are rich in historical and scientific value. In the continuous progress of history, the artistic styles of different eras have merged, and finally formed the very charming Dunhuang musical dance art, which has been widely welcomed. Under the background of the information age, people integrate digital technology with the Dunhuang fresco art of musical dance, which not only improves the preservation time of Dunhuang frescoes, but also allows this art to be presented to people and allows Dunhuang culture to be spread and inherited. The elements in the Dunhuang frescoes in our country are very rich and can be applied to all aspects. Many professionals have gradually realized its importance, and by transforming its creative vehicle, users can deeply understand and further appreciate the Dunhuang musical dance art and learn the knowledge of frescoes while experiencing the product. At the same time, based on the existing frescoes and restoration drawings created by researchers, combined with the special design principles of the product, a visual interface with a sense of structural hierarchy was designed. The classic Dunhuang fresco musical dance images are sorted out to build a rich material information database. At the same time, the interactive display is divided into different modules according to the research content of Dunhuang fresco musical dance art, and the content of the characteristics of the times, music meaning and dancing image are designed. Finally, Unity3D is used to realize the interactive display design of Dunhuang fresco musical dance art.
