Embodiment 1

[0082] A road network drawing device oriented to a simulation system, comprising seven parts: a map importing device, a node editing device, a road section editing device, a signal lamp editing device, an accident editing device, an OD pair editing device, and a road network exporting device. These seven parts are interrelated and used in the order of import, edit, and export. The function of the device is realized by using Visual Basic language, MAPX mapping component and ACCESS database, which not only realizes the editing function of various maps conveniently, but more importantly, can generate executable files, run independently, and improve the efficiency of road network editing. Convenience. The concrete function of device of the present invention is as follows:

[0083] 1. Road network introduction device

[0084] The purpose of this device is to generate road network files. There are mainly the following steps:

[0085] (1) Map import: including base maps and raste...

Embodiment 2

[0127] figure 1 As shown, it is a structural diagram of a simulation system-oriented road network drawing device and method (hereinafter referred to as: road network drawing device) designed according to the method of the present invention. The signal editing device, the accident editing device, the OD editing device, and the road network exporting device are composed of seven parts. These seven parts are interrelated, and these seven parts devices are interrelated. The function of the device is realized by using Visual Basic language, MAPX mapping components and ACCESS database, and it can run independently without any software; among them, the road network importing device is the first module of road network drawing, which is for future road network editing The output provides basic data support, and its data includes two parts: spatial data and attribute data. The spatial data determines the specific location of the edited object, and the attribute data provides the ident...

The device not only can realize visualization edit of the road network and improves the maneuverability of a simulation system, but also is developed based on visual basic and MAPX, so that an executable file can be generated, andthe device can be operated and executed independent of any other software, thus improving the convenience of the software can be improved. All the functions of the device can be realized by various relations and methods inside all devices and among different devices.

Description

technical field [0001] The present invention relates to a road network drawing device and method oriented to a simulation system, more specifically, to a road network drawing device and method for a general traffic simulation system INTEGRATION. The invented device not only realizes the visual editing of INTEGRATION's road network and enhances the operability of the simulation system, but also can be executed independently of any other software operation, which improves the convenience of using the software. Background technique [0002] Since INTEGRATION, a mesoscopic simulation system, can only recognize input files in text format, that is, users can only input simulated road networks by operating attributes in text files, and road network editing and modification work requires a lot of space. The input method of the file is not only difficult to input, but also error-prone and inconvenient to modify. In order to improve the utilization rate of the mesoscopic simulation s...
