Object-oriented Data Model of the Municipal Transportation
The transportation problem is always one of main questions each big city all over the world faces.Managing the municipal transportation using GIS is becoming the important trend.And the data model is the transportation information system foundation.The organization and storage of the data must consider well in the system design.The data model not only needs to meet the demand that the transportation navigates,but also needs to achieve the good visual effects,also can carry on the management and the maintenance to the traffic information.According to the objectoriented theory and the method,the road is divided into segment,intersection.This paper analyzed the driveway,marking,sign and other transportation facilities and the relationship with the segment,intersection and constructed the municipal transportation data model which is adequate to the demand of vehicles navigation,visual and management.The paper also schemes the the all kinds of transportation data.The practice proves that this data model can satisfy the application demands of traffic management system.
