The vigorous motorization process is taking place in a growing number of countries year by year, and the number of people involved in road traffic is constantly increasing. The growth of the vehicle fleet and the volume of transportation lead to an increase in traffic that in the context of cities with a historical build-up leads to a traffic problem. It is particularly acute at the junctions of the road network. There is an increase in transport delays, queues, and congestion, causing reduce in speed, excessive fuel consumption, and increased wear-out of vehicle components and assemblies. These questions are constantly analyzed both in theoretical and practical terms. Today, the negative effects of motorization cannot be eliminated, and effective measures need to be developed to reduce their negative impact on the urban environment. An irrational location of public transport stops leads to a significant increase in transport delays. Respectively, the objective is to determine the optimal layout of the public transport stops on the street network, taking into account the existing and designed traffic conditions.

Undertaking the subject of the application of telematic systems to improve the safety of road transport is caused by the increase of the mobility of the society, their transport needs, which in effect leads to the multiplication of the number of vehicles on the roads. The low level of construction of new roads and modernization of the existing ones is conducive to the occurrence of transport congestion, the number of accidents and road traffic difficulties, and has a negative impact on the natural environment. In the era of modern society, methods are sought that would minimize negative effects in the transport system, thereby increasing road safety. The purpose of this article is to analyse the use of Intelligent Traffic Light in the aspect of road safety. Traffic safety at intersections is reflected in indicators of dangerous situations with the participation of road users in its area. Hence, the selection of the research method and the place of the tests carried out. Implementation of telematic systems supports the construction of a secure road transport network. The authors of the article focused on the analysis of traffic hazards and their consequences in the form of wounded and dead people. In addition, the topic of safety in the road transport system was addressed very precisely, where it was discussed in terms of operation, economic, technical and environmental protection.

The Impact

The goal of smart cities and sustainable transport is to ensure the efficient movement of people while minimizing a negative impact on the environment. Many cities around the world conduct a policy aimed at limiting parking spaces; however, the complete elimination of parking spaces in cities currently does not seem possible. Parking vehicles cause disturbances in road traffic by searching for a parking space and performing the parking maneuver. This article analyzes the impact of the parking maneuver on the capacity of the inlets of intersections with traffic lights, and the significance of the time it takes to enter and exit a parking space on road traffic disturbance areas under Polish conditions. The research is carried out in on-street parking, characterized by different positions of the parking space to the road, the different surfaces of parking spaces, and the geometry of the road next to which the parking spaces are located. Differences in the time of entry to and exit from the parking space between the research areas indicate that different characteristics of the parking spaces affect the time of the parking maneuver. Drivers wait for the acceptable distance between vehicles on the road into which the vehicle can exit from the parking space. Drivers exiting from perpendicular parking spaces more often cause traffic disruptions than in the case of parallel parking spaces, due to limited visibility. The occupancy of parking spaces directly next to the analyzed ones also affects the time of entry to and exit from the parking space. However, between the time of entry to or exit from the parking space, and the use of the parking space, there is no relationship. This finding indicates that more factors determine the time of entry to and exit from the parking space. The results presented in the article show the need to conduct further research on the impact of parking maneuvers on the capacity of intersections with traffic lights for road traffic conditions in Poland. The results of the research will allow for the design and construction of an optimal parking infrastructure that will meet the needs of road users, while minimizing the negative impact on road conditions and the natural environment following sustainable development.

With the growth of the road transport fleet and increase of urban agglomerations, the availability of private transport on the streets of cities with a population over 500 thousand inhabitants is quite noticeable. The previously developed general plans of such settlements, in modern realities, are impossible to implement both from a financial point of view and in terms of the urban space organization. Given the impossibility of meeting the needs of private car users, public transport comes first in the priorities of urban mobility. Problematic areas of the road network in many western Ukrainian cities are those that are densely populated. In such cases, it is not always possible to redesign elements of street sections or intersections, so the traffic management improvement is limited to organizational measures. Among them, the most popular and least expensive are the change the modes of light control at intersections. Considering modern opportunities, technical means and scientific achievements, the capacity of signalized intersections is high. The same applies to the principles of giving priority to public transport over time (at signalized intersections). At present, a significant number of methods and algorithms for detecting and heading the movement of public transport at traffic lights have been developed, however, the criteria for the application of each of them are not fully understood. As a result of the conducted research, the change of queues in front of stop-lines at intersections depending on types of signalization is defined. The results showed that the existing type of control creates significant traffic delays on secondary streets. As a result, it is proposed to use adaptive control, which provides for the adjustment of the traffic light cycle in the presence of tram traffic. Using traffic simulation tools, it became possible to choose different modes of traffic lights control at intersections, which can provide public transport priority, while minimizing the negative impact on the adjacent elements of the road network.

The rise of motorized vehicle modification can have a negative impact if there is a lack of understanding from the public, which can endanger motorists on the road. Every party who wishes to modify a motorized vehicle is required to have a permit as required in Law Number 22 of 2009 concerning Road Traffic and Transportation. The problems in this thesis are 1) what are the types of motor vehicle modifications that violate traffic regulations 2) How is the law enforcement against motorized vehicle modifications that violate the traffic regulations by the Gianyar Police Traffic Police The purpose of this research is to add insight into motorized vehicle modification in accordance with applicable regulations. This study uses an empirical method and uses a sociology of law approach. The results showed that the modification of motorized vehicles had to be subjected to a retype test, and, tit did not carry out the type test it would have violated Article 50 paragraph (1) of Law Number 22 Year 2009 concerning Road Traffic and Transportation. Then law enforcement on motor vehicle modification has been optimal, but there are still several factors that hinder enforcement.

In this paper, research is done in the influence of different terrain and traffic conditions on road sections on the driver?s driving performances, i.e. on the car energy efficiency and CO2 emission. A methodology aimed at determining to which extent unfavorable traffic and/or terrain conditions on a road section contribute to the driver?s worse driving performances, and also to determine when the driver?s aggressive driving style is responsible for greater fuel consumption and greater CO2 emission is proposed. In order to apply the proposed methodology, a research study was carried out in a cargo transportation company and 12 drives who drove the same vehicle on five different road sections were selected. As many as 284 014 of the instances of the data about the defined parameters of the road section and the driver?s driving style were collected, based on which and with the help of machine learning a prediction of the scores for the road section and the scores for the driver?s driving style was performed. The obtained results have shown that the proposed methodology is a useful tool for managers enabling them to simply and quickly determine potential room for increasing the energy efficiency of the vehicle fleet and decreasing CO2 emission.

Eutrophication is one of the consequences of the negative anthropogenic impact on aquatic ecosystems. It leads to the degradation of both sweet and marine ecosystems, constituting a kind of secondary pollution of waters, which disturbs all types of their use. Undertakings related to preventing the negative effects of eutrophication are mainly conducted towards reducing the loads of nutrients introduced into surface waters and controlling the entire conditions in aquatic ecosystems in order to limit the development of aquatic vegetation. The increasingly restrictive legal requirement regarding the content of nitrogen and phosphorus in wastewater discharged into recipients enforces the application of expensive treatment technologies, and the public is becoming more aware of the rising costs of water and wastewater fees. In addition, wastewater treatment is a factor which has a negative impact on air quality due to greenhouse gas emissions and generates other environmental problems. The challenge for facilities, however, is determining which treatment alternatives will best meet their needs, both technically and financially, and to choose the most sustainable path. The problem of establishing a reasonable level of nutrient removal from wastewater, justified from an ecological and economic point of view is discussed in the paper.

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.
