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.

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.
