【摘要】：随着天津交通运输行业的迅速发展,公路密度随之不断扩大,市、区各地方交通主管部门对公路设施方面的管理越加重视。公路设施损益情况数据的调查,是一项可以获知公路设施好坏的必要渠道,但是,由于需要维护保养的设施量巨大且人员有限,致使我市的公路设施好坏的调查数据仍不够准确,设施维护和服务能力等方面做的仍不到位,针对这一问题,项目组设计并开发了公路设施管理系统。本文首先提出了业务数据与空间数据的完美结合,实现了让交通主管部门能够更加高效、便捷的管理交通路网,合理的利用资源,且系统可以清楚地显示各国省道等公路的路况路线信息,为交通主管部门提供了清晰、客观的事实依据,为管理提供了便利。其次,提出了数据检查自动化,数据错误做到自动识别、全自动化检查,可以为管理员提供错误报警、产生错误的原因、修改建议,减少数据修改工作量,降低人工操作的误差。最后,提出了数据处理自动化,可实现自动删除冗余点伪节点、自动删除碎线和空注记、自动拼接零散文字、辅助修改自相交线和回头线、辅助闭合多边形边线等,为数据处理人员减少了数据处理的工作量,提高了数据处理的精度。公路设施管理系统的设计与实现,为公路设施管理部门提供了便捷的工作方式。系统实现了对公路设施数据更新维护,定期检测、技术现状评定成果管理等功能,实现了对公路路政的有效监督。经过近半年的试运行,系统运转正常,无任何重大事故。
[Abstract]:With the rapid development of traffic and transportation industry in Tianjin, the highway density has been expanded continuously, and the management of highway facilities has been paid more and more attention to by the local traffic authorities in cities and districts. The survey of road facility profit and loss data is a necessary channel for information on the quality of road facilities. However, due to the large number of facilities requiring maintenance and limited personnel, As a result, the investigation data of highway facilities in our city are still not accurate enough, and the maintenance and service capacity of the facilities are still not in place. In view of this problem, the project team has designed and developed the highway facilities management system. In this paper, we first put forward the perfect combination of business data and spatial data, so that the transportation department can manage the traffic network more efficiently and conveniently, and make rational use of resources. Moreover, the system can clearly display the road condition information of provincial highways in various countries, which provides a clear and objective factual basis for the transportation authorities, and provides convenience for the management. Secondly, the automation of data inspection, the automatic identification of data errors and the full automatic checking can provide administrators with false alarm, cause errors, modify suggestions, and reduce the workload of data modification. Reduce the error of manual operation. Finally, the data processing automation is put forward, which can automatically delete redundant pseudo-nodes, delete broken lines and empty notes, automatically splice scattered text, assist to modify self-intersection lines and retrace lines, assist to close polygonal edges, etc. The workload of data processing is reduced and the precision of data processing is improved. The design and implementation of highway facility management system provide convenient working mode for highway facility management department. The system realizes the functions of updating and maintaining the data of highway facilities, checking regularly, managing the achievements of technical status evaluation, and realizing the effective supervision of highway administration. After nearly half a year of trial operation, the system runs normally without any major accidents.
