基于物聯(lián)網(wǎng)的城市交通改善對策研究
[Abstract]:In recent years, with the rapid growth of the number of private cars, traffic congestion has gradually become the normal traffic peak in large and medium-sized cities. Under the condition that the hardware such as urban roads has little room for improvement, the software of urban traffic system can be improved by reasonable management and control measures, which will improve the service level of urban traffic more effectively. As a high-tech industry supported by the state, the Internet of things has entered a period of rapid development, and its rapidly changing technology has provided many new breakthrough points for the improvement of urban traffic, but how to better integrate the technology of Internet of things into urban traffic, There is still much to be explored. At present, the application of Internet of things technology in urban traffic improvement mainly focuses on two fields: intelligent signal control and dynamic traffic guidance. In this paper, by analyzing the management and control strategy of urban traffic system, we study how to better integrate the Internet of things technology into urban traffic management. In this paper, the structure, equipment and related technologies of the Internet of things transportation system are introduced, and through comparative analysis, reasonable and feasible technologies and equipment are selected to construct the transportation system of the Internet of things in the study area. Based on the analysis of the drawbacks of the existing traffic management measures in the study area, the intersection signal control system, the variable lane signal control system, the regional traffic guidance system and the coordinated control strategies between them are studied in the environment of the Internet of things. In this paper, the methods of signal control, variable lane control, dynamic traffic guidance and parking guidance for intersections under the environment of Internet of things are proposed to improve urban traffic, and the feasibility of the scheme is analyzed. Combined with the practice, the paper simulates the traffic situation in the study area, and makes a comparative analysis of the traffic situation before and after the improvement. It is hoped that the theory can be combined with the practice and the theory can be applied to the urban traffic improvement.
