On The Road

Knowing the current atmospheric conditions of the roads is of great importance, both for road managers and for road users. RWIS stations record all relevant local atmospheric conditions in real time and transmit this information to control centers. This information has a dominant application in planning activities related to road maintenance in winter conditions. An analysis of the literature relating to the costs and benefits of RWIS stations indicates that their implementation in the transport infrastructure is not only economically profitable, but also offers a number of benefits such as more efficient road maintenance and facilitated organization of available funds, all for the purpose of winter road maintenance. Implementation of this system contributes to the safety of users on the public road network, as well as to the reduction of the number of traffic accidents in which the road and its condition are recognized as the cause. Twenty-eight meteorological stations were installed on the road network of the Republic of Serbia. On the basis of the historical data on the state of the roads from the mentioned stations in the previous period of winter maintenance and an individual implementation cost, the cost-effectiveness analysis of RWIS in the Republic of Serbia was performed.

National Economies

Road are significant national assets which provides a fundamental foundation to the performance of all national economies, delivering conditions for social and economic development of countries and international communities. It is of at most importance to ensure a mobile and safe movement of inhabitants with the lowest time and pollution costs. In order to reach the goals the planning processes are implemented on a national and international scale to rationally justify the efficiency of urgent measures. In the Republic of Lithuania, seeking to efficiently use funds allocated to the road sector the Road Maintenance and Development Programmes are developed by the road manager defining a short-term and long-term vision of the road network and measures to achieve it. However, due to the anticipated insufficient financing of the road sector the Road Maintenance and Development Programmes aim to rationally combine preservation of the road network and its perspective development depending on the existing financing. The Road Maintenance and Development Programme of the Republic of Lithuania for 2030 assesses the existing condition of the road network and defines the goals and measures how to implement a sustainable development in the road network. With the help of review analysis this paper studies: road safety assurance, road pavement deterioration degree, social welfare assurance, road maintenance, infrastructure development, assurance of sustainable development.

On The Road

Road management systems rely on the availability of quality information to make good decisions. A lack of information on the condition of the Canadian forest industry’s unpaved road network led to inappropriate management decisions. To fill this information gap the Forest Engineering Research Institute of Canada (FERIC) developed the Opti-Grade road management system. Opti-Grade is a low-cost tool that provides information about the road roughness and travel speed as the equipped road user’s vehicle travels on the road network. This information can then be used to focus grading activities where they will have the greatest impact on the road condition for the money invested. Further, over time, a history of the behavior of the roads can be built. With this history, degradation models can quickly and easily be produced to see which segments of the road network degrade the quickest and the most frequently. Problem segments can be identified. Valuable road evaluation budgets can then be focused on those sections to determine the cause of the problem. That will allow precious rehabilitation budgets to be focused where they can have the greatest impact. Opti-Grade is currently used by a large sector of FERIC member forest companies with payback periods shorter than 4 months. FERIC continues to improve the software to manage the data from the Opti-Grade system and increase the abilities of the decision support tools in the software.
