W36：道路财产管理IV
195泰国城市道路网络公路养护管理系统（简称PMMS）
作者：泰国，Chulalongkorn大学，Maitree Srinarawat
This paper presents the framework of the Pavement Maintenance Management System (PMMS) developed for the Department of Rural Roads, Thailand. The system consists of eight interrelated modules: (1) the Road Inventory Module, (2) the Road Condition Database, (3) the Maintenance Historical Database, (4) the Budget and Cost Database, (5) the Performance Analysis Module, (6) the Prioritization Analysis Module, (7) the Treatment Strategy Analysis Module, and (8) the GIS Interconnecting Module. The paper describes major components and main functions of each module, as well as the interface of all modules. The effectiveness of the proposed system is illustrated by implementing the system to establish an appropriate pavement maintenance policy for rural road networks in Thailand.
196与相关领域紧密相连的计算机化的系统
作者：法国，Autoroutes Du Sud De La France，Isabelle Simon
The company Autoroutes du Sud de la France manages a more than 2440 km motorway network in service including nearly 3600 civil engineering structures, 4600 hydraulic structures and 60 millions m2 road surface. It is the leading french company holding toll motorways concessions.
In order to optimize the management of such a heritage, computerized tools have been developed.
Elaborated in close link to users in the field in order to give the best answer to their necessities, three applications have been set up in different technical domains:
GOA is an information system used since 1994 that allows a detailed description of the all civil engineering structures, the follow-up and schedule of inspections and maintenance operations. Complementary, detailed inspections according to the IQOA French method can be made with a nomad appliance, from GOA data. The results are automatically integrated into the base with the calculation of a mark.
ARGUS is a « client-server » tool relative to pavement. It allows to stock and to make restitution of all necessary data to know the road surface state and offers the possibility to establish an expert valuation concerning the works to do. All pavement structures and maintenance works since origin (ones date from 50’s!) and auscultation measuring since 1991 are informed into the base.
SIGAL, a geographical information system, used since 2002, allows to inform and to visualize on cartographic background different objects of the heritage (traffic signing, portals, passages, hydraulic structures, noise barriers, tanks, buildings, crash barriers, pylons) with their follow-up.
These tools being used by a public of experts, some WEB applications have been developed in order to make accessible the ASF heritage to all those who are involved in the company. They allow visualizing on a cartographic backdrop the different objects coming from the specific databases with their follow-up, the exploitation through requests and the reports editions.
The presentation will describe the organization used to the heritage management with the help of these computerized tools and their interaction in a global process including the heritage inventory, the follow-up, the notation and index calculation and finally the projects planning.
197有关Grey系统方法数据库在道路交通事故中的应用的研究
作者：中国，（北京）交通大学，Yang Tianjun
Grey system theory is an effective tool for system analysis, modeling, prediction, making decision, and control on poor information system, abroad applied in the fields of engineering technology, society economics and etc. This paper discusses the application of grey system theory to dada mining in poor information systems and proposes some corresponsive algorithms and system structure. The major factors affecting the traffic accidents have been relatively analyzed, basing on the accidents of one city. The importance of each factor could be made clear and the work of the traffic management department could concentrate on some main problems so that the traffic accident could be reduced.
198用养护信息管理系统进行养护活动
作者：日本，Hanshin高速公路局，Satoru Nozak
Accurate and up-to-date data of individual structures is essential for proper repair and maintenance. The structure data includes asset, inspection and repair information and takes various forms such as diagrams, documents, drawings and photographs. The maintenance information management system (MIMS) of the Hanshin Expressway Public Corporation (HEPC) consists of the maintenance information database as huge data storage and the management system for collective data management. Since its foundation about ten years ago, MIMS underwent many improvements to support optimal maintenance planning. Visual information, which is easily understandable, is adopted in greater numbers, and a client-server system enables quicker data entry and transmission. Recently MIMS is equipped with all necessary functions as a data management system to support proper repair and maintenance.
As a utilization of the MIMS, HEPC has examined a bridge management system for elevated structures, which constitute major parts of the Hanshin Expressway. This system was intended to aid the optimization of the repair and other related costs to support proper maintenance on a long-term basis as well as short-term repair planning. In the case of the pavement, we use the maintenance control index (MCI) obtained from the pavement inspection results and the number of years from the latest repair. The life cycle cost (LCC) was defined as the sum of the direct cost (repair and maintenance costs) and the user cost for the future 100 years converted into the present values at the social discount rate. The optimal time for repair or the optimal management rules were obtained for individual paved sections by determining the minimum LCC. The future repair and maintenance costs were calculated based on the optimal time for repair obtained: for the limited budget cases, with the priority of each repair project being determined according to the cost-benefit ratio.
More efficient data processing and analysis of the MIMS will allow the improvement of the bridge management system and prediction of structure damage and more accurate causal investigation, eventually leading to the establishment of the rational maintenance method in the future.
