PURPOSES: Regional offices of the Ministry of Land, Transport and Maritime Affairs use a computerized system called KAMIS so as to manage road equipment systematically. Road agencies can record number of operating days by equipment, actual working hours, accumulated operating hours (or distance) by equipment, and operating cost. However, KAMIS does not provide critical information, although it is strongly related to efficient road management equipment operation. In other words, road agencies do not know whether they have sufficient equipment to handle their actual work. METHODS: Therefore, this study suggests a methodology to evaluate for operational efficiency of road management equipment using analytical hierarchy process(AHP). First of all, estimated weights related criteria can be produced by AHP, and then use operational history by pieces of equipment. RESULTS: Results show that importance of management work can differ from weather conditions through five areas. CONCLUSIONS: Commonly, this results can imply to help save money for the purchase and maintenance of road management equipment, and they would improve the functional performance of KAMIS.

After insufficient road facilities are expanded, it is more important to maintain performance of road facilities the time according to passing. When the road facilities are maintained optimally through proper maintenance, the total amount of investment can be minimized and national competitiveness is improved. Individual maintenance research of road facilities such as PMS or BMS was in progress until currently, but it is difficult to joint ownership and share information between systems, and it is impossible to use as the decision-making. Therefore, Asset Management System for road facilities is enforced to solve the inefficiency of existing systems, maintenance the road facilities systematically under the limited budget and get the maximum benefits against the cost from the view point of long-term. In this paper, the concept of Asset Management System explained, and research plan from KICT in order to introduce the Asset Management System of road facilities from 2008 hereafter for 5 years accounted.

Because the cost of road management is increasing proportional to road construction, there are needs to build general and systematic road management system. To solving such problems, Ministry of Construction and Transportation started research and development of Highway Management System(HMS), and established a foundation for systematic road management system. But, the implementation of HMS has some limitations because it is just converting roads of physical space to roads of electronic space and managing roads of electronic space. Although HMS offers many conveniences compared to old system which was based hard-copy and paper maps or unit operations, it can not overcome the problem of inefficency of road management due to the separation of operation between outer field and inner office. Therefore, to overcome such inefficency, this study focused on Road Disaster Management System development based on Ubiquotous.

Since 2010, RDA has discovered 30 Green-Road as the way of developing rural area. However, results from conference with expert and village leaders of Green-Road concluded that there were problems such as little financial benefits due to mismanagement and needs of improving the efficiency of management. In order to respond to these issues, this research has conducted empirical investigation about the status, management of Green-Road and its influences on local area. Main purposes of this investigation was to reveal the various obstacles in road management, and to find better ways of road management. To accomplish the goal of research, this study conducted survey and interviews with leaders in villages. Particularly, the investigation had focused on the specific management issues suggested by village leaders. Based on the results, this research suggested establishing a committee for creating leaders network and developing effective management method in order to improve road management and its consequences.

Development of industry is increased Traffic Volume and have brought increase of road. As a result, Maintenance-management expense of the whole road is rapidly increase. Operation of PMS (Pavement Management System) need that it is efficiently for maintenance-management the whole road network Into budget limited. PMS is effective management through Investigation of roughness, crack, plastic deformation, etc of road. Advanced nation recognizes necessity of maintenance-management of road, progress to investigation and research. Our country is lacking that systematic pms's application and research. Therefore, this research estimated using of surveying method of DGPS that roughness of road for investigation-step of PMS. At the future, this paper may contribute in research of automatic surveying system for road surface.

Road sign is one of the road attached facilities to provide conveniences to motor drivers. The setup of location information according to the related regulation and the inclusion of various attributes such as place names, route numbers, symbols, bearings, distances to the place of interest distinguish the road sign from other facilities. These features give advantages to the informationization of road sign. Presently there established about 130,000 road signs on each class of roads, and about 280 road management offices have controlled these road signs independently, but there are plethora of ineffectiveness such as the lack of consistency, recognition, connectivity, and location suitability etc. These are the major factor of confusions rather than providing conveniences, and arisen a lot of public grievances. Accordingly, in this research the road signs throughout the nation were databased and the web-GIS based road sign management system was established to ameliorate the problems reveled. Since the road sign management system we developed reflected the demands of the persons in charge and users, the management effectiveness might be enhanced and the public inconveniences will be reduced.

India has accorded a high priority to road infrastructure development through Public-Private Partnership (PPP) and it has set a high target for investment inflows. Yet, it is widely held that road/highway infrastructure has not been developing at required pace and that the road infrastructure projects under PPP have been suffering from several hurdles and delays, thereby affecting project success/failure. This paper is an attempt to analyze the critical success/failure factors of road infrastructure projects under PPP in India. A questionnaire survey was conducted among a sample of the stakeholders of road infrastructure projects to identify the critical success/failure factors during all four major project stages using different approaches. Initially, the critical factors were identified through ranking based on the average/mean score. Later, the conventional RII score was used to identify the critical success/failure factors. Finally, the critical success/failure factors were also identified based on the stakeholder-wise ranking of the factors and their convergence. The assessment revealed that there was a greater convergence across the different methods and also that there was greater consensus among project stakeholder on the critical success/failure factors of road PPP projects.

Information and communication technology (ICT) is a promising solution for mitigating road traffic congestion. ICT allows road users and vehicles to be managed based on real-time road status information. In Tanzania, traffic congestion causes losses of TZS 655 billion per year. The main objective of this study was to develop an optimal approach for integrating real-time road information (RRI) to mitigate traffic congestion. Our research survey focused on three cities that are highly affected by traffic congestion, i.e., Arusha, Mwanza, and Dar es Salaam. The results showed that ICT is not yet utilized fully to solve road traffic congestion. Thus, we established a possible approach for Tanzania based on an analysis of road traffic data provided by organizations responsible for road traffic management and road users. Furthermore, we evaluated the available road information management techniques to test their suitability for use in Tanzania. Using the floating car data technique, fuzzy logic was implemented for real-time traffic level detection and decision making. Based on this solution, we propose a RRI system architecture, which considers the effective utilization of readily available communication technology in Tanzania.
