The new requirements set for tram loops mean that all stakeholders' expectations regarding their safety and functionality change. This creates a need for new tools for tram loop assessment, which are important interchanges, especially for people living outside the city limits or on their outskirts. The aim of the authors ’research is to create a indicators for assessing the safety and functionality of tram loops. Therefore, the article presents an overview of the research results in the area of tram transport and interchanges safety. Then the proposed indicator assessment for tram loops was described.

Bus stops are an essential element of the public transport system and affect its users’ safety level. They are where the passengers gather who want to use bus transport, and where vehicles stop to exchange passenger flows. Most studies devoted to assessing bus stops’ safety focus on two evaluation methods: (1) statistical analysis of traffic crash data and (2) traffic conflict analysis. However, there is a need to develop a methodology to define priorities and scope for the improvement of increasing bus stops’ safety. For this reason, the aim of the article is to present a method of assessing bus stops’ safety, which is dedicated to the process of auditing and designing point infrastructure in the city. The use of the proposed method of evaluating bus stops is aimed not only at determining the current status, but above all at assigning priorities to actions aimed at increasing safety and improving the quality of life of residents. The article presents in detail the algorithm of the research procedure consisting of the proposed method and its implementation for the evaluation of stops in a selected city. In total, 151 bus stops serving all fast lines in the studied agglomeration were assessed. As part of the results, the ratings obtained by individual stops were presented. The level of fulfilment of individual evaluation criteria, divided into conducted classification procedures, was also analysed. The implementation of the method in the real system allowed us to assess the correctness of the procedure and the usefulness of the obtained results. The obtained results of the evaluation of bus stops and the fulfilment of individual criteria should constitute the basis for the created schedules of the required ongoing works related to the improvement of public transport passenger safety, but also the creation of long-term plans related to the improvement of the bus stop infrastructure and its adaptation to changing safety requirements and passengers’ expectations.

The safety of public transport stops is the subject of numerous studies in large agglomerations around the world. This is due to the fact that it is a passenger exchange zone where collisions and accidents involving people getting on or off public transport vehicles most often occur. For this reason, the purpose of the article is to present the results of the safety assessment of the stop zones for two selected tram lines in Wroclaw. The assessment of tram stops is based on an indicator that takes into account three parameters that affect the safety level of the tram stop zone - the location and infrastructure of the tram stop, its availability and traffic in the tram stop zone. The analysis of stops has been prepared on the basis of direct observation. As a result of the assessment process, these stops were indicated, whose safety index was the lowest. The improvement solutions for them should be prepared at first.

Relationship between functional and also efficient working of urban transport and totality of social as well as economic dimension of life at urbanized area shows huge impact of urban transport at public life. It is one of the reasons that its prosperity is an object of interest of passengers, haulage contractors and persons responsible for management at the agglomeration. Because of the causes given above authors decided to choose as an object of studies the risk associated to travelling with urban communication by the residents of chosen agglomeration. The assessment of this risk includes aspects of safe travel as well as logistic support provided to passengers. Both of this factors determine the quality of service given by collective communication system. The purpose of the article is to present results of researches made through surveys collected in Wroclaw among passengers of public communication.

Interchanges are a key and the most complex element of a road infrastructure. The safety and functionality of interchanges determine the traffic conditions and safety of the entire road network. This applies particularly to motorways and expressways, for which they are the only way to access and exchange traffic. A big problem in Poland is the lack of comprehensive tools for designers at individual stages of the design process. This applies to guidelines or other documents regarding the location, choice of interchanges type and selection of design pa-rameters. This does not provide sufficient material for designing safe and functional interchanges. This situation results in numerous hazards that occur on existing interchanges and errors that are still being made at all stages of the design process. Consequently, there is a risk of accidents in the area of interchanges, which often have serious consequences. The purpose of the research presented in the article is to identify main groups of hazards on the interchanges and to classify them based on field tests and audits of project documentation. The prepared classification uses the results of analyzing data on road accidents. As part of the research, a database was built that includes in-formation on road accidents and traffic, as well as data on all existing interchanges on motorways and express-ways in Poland. These data includes: interchange type, length of exit and entry lanes, total interchanges length, type of cross-section on main roads and ramps. The number and type of ramps occurring at a given interchange as well as the type of intersections, if any, were also taken into account. Based on the assessment, the level of safety was determined for individual types of interchanges. Then, the impact of selected road and traffic factors on safety was presented. The critical elements of interchanges are entries, exits, weaving sections and intersections. Assumptions were also adopted for the classification of identified haz-ards. A comprehensive safety assessment for interchanges allowed the development of assumptions for their design guidelines. On the basis of database exploration and field research, the main problems and hazards regarding the functioning of interchanges were identified.

Travel comfort depends on many criteria, including, to a large extent, the passenger's sense of security while waiting for the vehicle and while driving. For this reason, tram stops play an essential role in the overall assess-ment of the functioning of the tram system in cities. The presented results of the literature review indicate that few publications related to safety in the tram transport system concern aspects of the infrastructure of stops. The arti-cles we distinguished in this area also prove the lack of publications in which the researchers focus on the criteria for assessing the safety of tram stops. The paper aims to present the results of research conducted among experts, which concerned identifying criterions influencing the safety of tram stops and the selection of criteria for their evaluation. In addition, the obtained results are the basis for further analysis of safety at tram stops. The research was conducted among experts representing almost all cities in Poland with a tram service system for residents. The obtained results showed that the critical elements from the safety point of view are those related to technical aspects, i.e., length, width, and height of platforms, which are adapted to both the rolling stock and the size of passenger flows. The second significant group of criteria determining the safety of stops is equipping them with elements supporting their use by people with disabilities, i.e., placing warning fields at the edges of the platform, designating a waiting area for people with reduced mobility, or the use of guiding lanes. It is also crucial to main-tain adequate separation of traffic between its various participants so that other people do not use the waiting and passenger exchange zone. The results obtained as part of the analysis will form the basis for the development of a detailed method of assessing tram stops in Poland in terms of their safety.
