A Review of GIS Technology Applications in Transportation Planning and Management

With the rapid development of the economy, the scale of urban construction is expanding, the corresponding transportation infrastructure is also improving, and the traffic congestion problem is becoming more and more serious. The application of GIS technology to transportation management can effectively alleviate the problem of urban traffic congestion at this stage, thus improving the operation of road traffic. This paper describes the advantages of GIS technology in transportation planning and management from the aspects of accuracy, measurement convenience, visualization, scientific, dynamic, data management, and introduces its application initiatives in road design, traffic prediction, vehicle guidance, traffic system design, traffic analysis. The application of GIS technology in transportation planning is becoming more and more extensive and profound, the technology can provide ideas and technical support for modern transportation planning, but also can combine the construction of road transportation system with information technology, effectively improve the rationality and scientificity of the transportation planning program, and play a positive and significant role in reducing traffic congestion and improving the efficiency of traffic operation.
