Instabilities of the ground is regarded as one of the most serious problems that affect many areas in Morocco. The study is important and beneficial because it concerns various sections of the Rif area. Indeed, certain zones which came at the top have been seriously affected. Disorders are numerous: destruction of homes, loss of agricultural land, and deterioration of infrastructure (roads, railways, and bridges). The aim of this study is focused on the zones where the road network generally is much damaged. This, however, causes a disturbance and even an interruption of the road traffic during stormy periods. The detailed study of lithology, climatology, geomorphology, hydrology, and the slope of the studied zones allows us to highlight the characteristics of the unstable grounds. It also helped us to figure out that the rheological nature of the ground plays a significant role in the characterization of the type of movement.The analysis of various movements which was found enables us to conclude that an instability of the ground depends on the conjunction on many factors, whether they are of provision or release. The most important factors causing the instabilities of the ground are: The alternation of rocks of nature; permeability and plasticity were well contrasted. The rugged relief and steep slopes. Geotechnical properties. Seismicity. Irregular rainfall. Geomorphology and land use. Anthropogenic action. Spatial distribution of the risk zones shows that the majority of the studied sections experience strong risks and medium risks levels.

Abstract Forest degradation can increase the level of disaster risk, particularly landslides. The impact of landslides, especially in Labuhanbatu Utara Regency, North Sumatera Province, socio-economic, physical and environmental losses that are directly perceived by the community in the disaster site. The study objective was to analyze the distribution of landslide vulnerability levels in the Labuhanbatu Utara Regency. The spatial distribution of landslide vulnerability level used spatial modeling with the Storie Index method with four variables, including rainfall, slope, soil type, and land cover type. The spatial distribution of landslide vulnerability level was mostly at a very low – low level with a percentage of 57.6% of the area of Labuhanbatu Utara Regency. Areas that occupied high – very high of landslide vulnerability level with the largest area were in three districts, including Na IX-X, Aek Natas, and Kualuh Selatan. Landslide prone areas are generally located on plantation and agricultural land use and also distribute on steep slopes. Various parties need to reorganize community activities in areas of high – very high landslide vulnerability to reduce disaster risk.

The Road

In the recent decades, we have witnessed an increase in the number of vehicles using the road infrastructure, resulting in an increased overload of the road network. To mitigate such problems, caused by the increasing number of vehicles and increasing the efficiency and safety of transport systems has been integrated applications of advanced technology, denominated Intelligent Transport Systems (ITS). However, one problem still unsolved in current road networks is the automatic identification of road events such as accidents or traffic jams, being inhibitor to efficient road management. In order to mitigate this problematic, this paper proposes the development of a technological platform able to detect anomalies (abnormal traffic events) to typical road network status and categorize such anomalies. The proposed work, adopts a complex event processing (CEP) engine able to monitor streams of events and detect specified patterns of events in real time. Data is collectively collected and analysed in real-time from loop sensors deployed in Slovenian highways and national roads, providing traffic flows. This prototype will work with a large number of data, being used to process all data, complex event processing tools. All the data used to validate the present study is based on the Slovenian road network. This work has been carried out in the context of the OPTIMUM Project, funded by the H2020 European Research Framework Program.

Road Tunnels

Tunnels are underground passages, placed horizontally, which serve to lead the road through them. In order to fulfill its purpose in road traffic, the tunnel must fit into the traffic infrastructure and as such not create an obstacle in movement and enable the movement of vehicles from entrance to exit without danger, but with increased restriction of freedom of lateral evacuation. Tunnels are among some of the most risky parts of the road network, primarily due to space constraints, where there is a possibility of a traffic accident. Managing the risks associated with the passage of road traffic, and in particular the safety of traffic in tunnels, is a serious problem in many countries. With the growing number of road users, it is necessary to adopt stricter standards regarding road tunnels. In addition to meeting these safety standards, factors such as operational requirements, economic efficiency, energy efficiency and state-of-the-art technology should also be taken into account when planning and equipping tunnels.

The paper considers the problem of improving the level of road traffic services. The level of service for various categories of city streets in practice does not correspond to the values given in normative legal documents. Therefore, the task of increasing the level of service to the indicated values on the road network is urgent. Herewith, it is important to specify the object of improvement, namely, the basic street-road network, through which the bulk of the transportation correspondence is implemented, since it is there that the greatest loss of the user time occurs. An effective tool in this work is the development of a set of measures using simulation modeling aimed at improving the level of traffic services on the street-road network.

AbstractMilitary actions generally unfold rapidly in different operational environments for which the commanding officer has assess the bearing capacity of the prestressed concrete bridges existing in the country’s road network. The bearing capacity is the maximum weight of the predetermined constitution convoy, which may safely circulate on the bridge, in stable conditions, considering the physical condition of the bridge. The paper shows that the bearing capacity will be assessed only through a technical analysis performed by an authorized expert together with a military engineer specialized in genius. This experts report will compare the initial condition of the bridge to the present one. The initial condition is based on the research of the execution design; the year of elaboration; the standard loadings at the moment; proprieties of the used building materials; execution modality, possible alterations occurring during execution as to the initial project. These data, together with the road traffic census, can be obtained from the company administrating the road network where the bridge is located. The current state to be assessed through analysis, calculation and static loading tests, showing if the capacity of the bridge can to support the increase of traffic military vehicle loading and reduction of the bearing capacity due to fatigue phenomena in the reinforcement. The paper proposes that authorities draw up and approve a standard concerning the verification periodicity of the bearing capacity in the existing prestressed concrete bridges.

The Road

The national project “Safe and high-quality roads” is aimed at the development, creation and effective use of intelligent transport systems. Today, there are many technical solutions to improve road safety, as well as optimize the process of organizing traffic. Often, these solutions lie not only in the plane of design, in the use of technical means for organizing traffic, in reconstruction of the existing street-road network, but also in the use of intelligent transport systems. The article has developed a concept for the development of a road-road network in Khabarovsk, in connection with the adoption by the Government of the Khabarovsk Territory of a decision on the construction of a transport interchange at the intersection of Voronezh-Bolshaya Streets in Khabarovsk, as part of the national project “Safe and High-Quality Roads” in the Khabarovsk Territory. The collection and analysis of statistical data, over a five-year period, on the types of frequency of occurrence of reported road traffic accidents. Visual and grapho-analytical methods identified the focus of the concentration of traffic accidents at the considered site of the road network of the city of Khabarovsk. Based on the method of conflict points, factors that influence the accident rate of an existing section of the road are studied. Several options for improving the quality and safety of traffic are considered: changing the number of lanes, regulating the traffic light, building a multi-level traffic intersection. Using modern software systems, based on methods of mathematical modeling, for several options developed models of traffic flows, identified the maximum possible comfortable and safe traffic conditions. Substantiated recommendations are given for improving the quality and safety of road traffic by improving the existing road situation.

Jl. Yos Sudarso is one of the centers of movement in Tarakan or a business zone. Jl. Yos Sudarso has experienced an increase in road load and a decrease in the level of road services which will eventually cause traffic problems, namely the effectiveness of reduced traffic performance. To find out the analysis of traffic performance due to the arrangement of the vehicle movement system on Yos Sudarso Tarakan road, traffic surveys are carried out, such as traffic volume, traffic speed, road capacity, and degree of saturation. After the road performance analysis, the characteristics and conditions of the road were obtained, the average total volume was 1399.92 pcu / hour, the average degree of saturation on the Yos Sudarso road in the direction of Kusuma Bangsa was 0.53, while the direction of Mulawarman was 0,55. Thus the average performance along Yos Sudarso road includes the C service level. By looking at these conditions it is necessary to increase the clear traffic flow regulation system such as traffic signal so that it can reduce the congestion that occurs on these roads. The construction of the coastal road frontage line and the construction of the access road network will provide benefits in the form of a road network in the western part of Tarakan city, reducing traffic density points.

In this paper we examine the major effects of road network attributes in a metropolitan area on the spatial distribution and intensity of activities, and suggest a model to describe these effects. The model is based on the hypothesis that the transportation system affects land development primarily as a constraint: the intensity of land use in an area cannot exceed the capacity of the road network that serves the traffic it generates. With the model we examine the feasibility of a proposed land-use plan (or prediction) for an urban area, given a proposed transportation plan. If road-capacity constraints are violated, the model employs an optimization procedure to identify a feasible spatial distribution of the activities. In this paper we describe the conceptual basis for the model and its formulation as a distance-minimizing optimization problem, a heuristic solution method, and a simple application.

Road traffic is the most used kind of transportation which has a lot of benefits. Except of these benefits, the road traffic causes a lot of negative impacts like a congestions, air pollution and noise. The proposal of European Parliament is reduction of these impacts by their inclusion to the road charges. In the annex of amending directive 1999/62ES are stated prices for congestion and external costs. If the member state wants higher amount like are stated, they have to be calculated. One element of external costs is noise costs. Noise from road transport causes health problems and has annoying effect to people. In this article, it was processed proposal of noise charges quantification, which consist of a few steps. This process was applied for quantifying noise charges with real values for Slovakia and Slovenia.
