Construction of Urban Traffic Spatial Information Database

With the continuous expansion of urban scale, urban traffic congestion has become an important factor restricting urban development. How to reduce the cost of travel time and realize the speed of urban traffic has become one of the important issues of urban traffic management department and the primary consideration of people's travel. When traveling, people often use a variety of path query software to query the optimal path to the destination, which are based on good road network data. Taking Xintai city as an example, this paper discusses the establishment of xintai traffic spatial database, and studies the whole process of road network data acquisition, data editing and processing, data storage and data release. On the basis of analyzing the purpose and significance of building traffic spatial data database, this paper carries out demand analysis, user analysis, feasibility analysis and system hardware and software configuration, and discusses the process of building database in detail. According to the classification and classification of urban roads in Xintai city, combined with the current situation of traffic data in the research area, various road network data at all levels were collected and ArcMap was used for data processing, editing, supplement and topology inspection. The traffic spatial database of Xintai city was established through ArcCatalog. Publish data on ArcGIS Online and ArcGIS Server to realize data sharing.

I. Introduction

With the continuous acceleration of urbanization, urban population and vehicles increase rapidly, and the problem of urban traffic congestion is becoming more and more serious. A large amount of time is spent on commuting, which virtually increases the time cost of people's travel and greatly affects the working efficiency of urban people. How to reduce travel costs and save travel time has become the primary consideration of people's travel. Many people will choose to query the current traffic situation through the relevant software to choose the optimal travel route. These need to be based on good road network data in software, which is the basis of path query. Spatial database building urban transportation network, therefore, for people to travel, to fully understand the urban traffic status, relevant departments of city planning, construction and management to provide important basis, can also be used for other sectors of the city, such as administration, education, fire fighting, emergency ChuJing, health care, business, etc all have important practical significance. Taking a certain city as an example, this paper tries to establish urban traffic spatial database to provide data basis for the subsequent realization of intelligent traffic.
