Local roads (V class roads) and the bridges on them compose a significant part of the public road network in Latvia. On local roads are around 45% of all bridges located on the national road network. These are mostly reinforced concrete bridges with short or middle span lengths, with one or two traffic lines. Due to low traffic flow, these structures are used lover maintenance classes. The lover maintenance class also includes less de-icing salt in winter maintenance and less founds for maintenance works. At the same time, some of these bridges are located on routes used by heavy timber trucks or trucks taking sand from quarries. Also, agricultural machinery and local people cars are using these bridges for everyday needs. Therefore, the safe exploitation of these structures is essential. Due to different service conditions, the development of deteriorations also will be different. This paper aims to study the development of characteristic types of damages, its causes and consequences and impact on structural performance and service life.

Railways are a mode of transportation that is being liked by the public because of its efficiency. The train has its own road in the form of rails, it doesn’t mean the train doesn’t intersect other transportation. The train crossing is a conflict area for public road users with train. This includes train crossing at Kenjeran street. The kenjeran street itself is a national road that is quite strategic because it is one of the accesses to the Surabaya-Madura toll road. The research this time aims to find out the security aspects that must be improved at the train crossing kenjeran street. Including rider behaviour at the time of the train crossing. The method used for this research is direct observation of the field and also shares questionnaires to find out if a public road user understands regulations while on a train crossing. The research results of many signs or road markers are incomplete so that many road users do not know that in front of the train crossing. Other public road user behaviour is also a lot of offense.

Under the Soviet regime and as part of the development of the economy, the Latvian road infrastructure and its associated landscape went through major changes. Through modernisation old roads were straightened, historically established road routes and their surroundings changed, new roads planned and constructed, some elements of the road landscape disappeared and new ones emerged. Snow and wind protection hedges were planted along open stretches. With the increase of public transport many unique bus stop pavilions rest areas for drivers and tourists were constructed. A lot of attention was paid to roadside views and aesthetics through the use of tree plantings. The aim of this study was to explore the heritage of road planning and landscape development in Latvia during the Soviet era from 1945 to 1991. The study used literature review and analyses of maps and archival materials from the Latvian road museum supported by fieldwork. Elements which are disappearing as the road network is upgraded through European structural funding were identified through map analyses of different time periods and a number of field studies of sample stretches of roads, were undertaken. The road infrastructure and the landscape of that time is part of the cultural heritage of the 20th century and is connected to the development of the rural economy and collectivisation and to military preparedness. The study uncovered a well-developed road planning and landscape design theory which was applied in Latvia and used as an example in other Soviet Republics.

The development of the national road network, its constant expansion and modernization is the basis for the long-term economic and civilization advancement of the country. Before accession to the European Union in May 2004. Poland had the least developed road infrastructure among all the candidate countries. From 25.05.2003 in polish legal system is in force the Act concerning the preparation and implementation of investment in public roads. The intention of the legislature was to simplify the procedures for the preparation and realization of investments in public roads to enable creation of efficient transport connections via a modern network of highways, expressways and roads of other categories. Special road act is a legal tool by which the national road network can be developed efficiently and in a simplified way.

Distance is one of the important factors in determining transportation cost and travel time, and it can be easily estimated by measuring the circuity of road networks. This study calculated the circuity factors to estimate the network distance for 27 forest roads (about 105 km) in South Korea. For this purpose, ridge, mid-slope, and valley roads were classified according to the construction location of the mountain slope, and the weighted and unweighted circuity factor (each 500-m section) were calculated. The average value of weighted circuity was 1.55: mid-slope roads (2.09), ridge roads (1.36), and valley roads (1.09). The average unweighted circuity factors were 1.61 for mid-slope roads, 1.21 for ridge roads, and 1.07 for valley roads. This study found that the circuity of the forest road network was most affected by the mountain terrain. In addition, the circuity factor increased with increasing network distance in the mid-slope roads but was not affected by the network distance in ridges and valleys. To improve the efficiency of transportation in the forest road network, it is important to locate the ladings and properly connect with the public road network.

The article reconstructs the public road network of the Grand Duchy of Lithuania (hereafter referred to as the GDL) in the 16th–17th centuries, and discusses its structure. In the historical sources, special terms describe public roads (highways), which are also called “big”, “great” or “eternal” roads. These were long-distance routes that connected urban, economic, and political centres. Roads and local pathways led towards them. The structure of the public road network in the Grand Duchy of Lithuania was based on the distribution of settlements and towns in the country. The densest public road network as in the western and southwestern parts of the GDL; meanwhile in the east of the country it was rather sparse. It depended on geographical features, as the eastern part of the country was marshier and woodier. Besides, the population of the eastern part of the GLD was affected by wars with Moscow. Active development of internal colonization could be observed in the western and southwestern part of the GDL. Intensive life was also affected by the concentration of the sovereign’s estates. All this encouraged the mobility of the population. The cities in the west and southwest of the GDL were enlaced in the network of public roads and were actively involved in the system of land transport and communication. Part of them attracted population not only locally but also from the entire region. During this research, a special scheme map featuring all public roads in the GDL in the 16th–17th centuries, as described in historical sources, was drawn. A separate list of sources, which is the scientific apparatus of the scheme map, is vailable.

The road network in the Republic of Croatia is well developed and largely responds to traffic needs. The motorway network is largely built up and no major new investment is needed in the short term. The national road network is in good standing according to national and EU standards. However, public road management companies face operational and financial challenges in terms of: (a) overinvestment in the network; (b) weak governance; (c) high operating costs; (d) large debt stock; (e) short tenor of existing loans; (f) currency risk and (g) insufficient credit strength to access the loan market for long tenors on a stand-alone basis. The Government of the Republic of Croatia has therefore decided to address these chellenges and launched a project funded by IBRD called the Modernization and Restructuring of the Road Sector (MARS) aiming to enhance operational efficiency and improve the financial sustainability of the road sector. To these ends, the Government has approved a Sector Policy Letter, which contains a set of planned reforms. To ensure the contribution of the road sector to the overall economy, in addition to the financial sustainability of the sector itself, operational improvements are needed in the following key areas: (a) management of the road infrastructure sector; (b) planning, financing and implementation of investments in the road sector; (c) corporate governance and business operations. Much of the reform has already been implemented, but some of the most important are still in the process of being implemented.

<p>Many developed countries have a national road network including a significant number of bridges in need of renovation or replacement in the coming years. The reason for this is their technical and functional capacity becoming insufficient due to aging and changes in societal demands. Therefore, these bridges need to be adjusted or replaced. National authorities in The Netherlands currently require a design life of 100 years for new bridges, however nowadays it seems reasonable to have a certain flexibility for this parameter. Since the selected design life has its implications on structural solutions and choice of materials, the identification of the optimal design life for bridges seems necessary. This paper gives a summary on the issue regarding the optimum design life of bridges and it highlights the framework of the upcoming research activities.</p>
