Opis:: The article proposes and discusses the application of AFS system in trams. The author of the present publication substantiates the need of introducing the solution of foreground lighting of a vehicle, which has already proved effective for motor vehicles, taking into account the specificity of movement of a tram being one of the main means of transport within the framework of urban public transport system. Using the results of laboratory photometric measurements for currently used optical light systems of tram 's head lights, a proposal for the use of new light beams has been presented. The method of realization of adaptive system of light beam control of tram 's head lights has also been demonstrated. In relation to the current photometric requirements in standardization guidelines concerning head lighting of a tram, directions ofchanges have been proposed. Light beam shape of main lights in tram 's foreground defined by isolux range, proposal of automatic light beam control system of a tram, proposal of arrangement of system reflectors within the area of tram car's front are presented in the paper.

Opis:: Researches in the field of technology of modern sources of light have called for the introduction and application of a few basic hardware solutions of automatic correction systems of light beam position in the vertical and horizontal axes of a vehicle. Application of Adaptive Frontlighting Systems in motor vehicles has made it possible to adapt light parameters of head lights and fog lights to the actual situation on the road. The system ensures optimal observation conditions of a vehicle's foreground. These systems have contributed to the improvement of driving safety and comfort in the conditions of restricted visibility during fogs and precipitation. The authors of the present publication substantiate the need of introducing the solution of the foreground lighting of a vehicle, which has already proved effective for motor vehicles, taking into account the specificity of movement of a tram which is one of the main means of transport within the framework of urban public transport system. The article presents the current standardization requirements concerning head lights for the abovementioned means of transport. The results of laboratory photometric measurements for currently used optical light systems, as well as the results of simulation researches of the foreground lighting of a tram in street traffic have been demonstrated. Moreover, the article presents the analysis of potential solutions for the foreground lighting of a traction vehicle with the application of automatic system of light beam control. The proposal of a method of light beam choice taking into consideration specific movement conditions of a tram has been presented. Attention has been paid to the expected exploitation and economic effect of the application of the system for a company promoted to be used in a tram, as well as to the improvement of working conditions of a tram driver and the influence on other public transport users connected with travel safety and comfort. The publication emphasizes the merits of the proper use of already existing lighting solutions and their introduction into street traffic system of a tram. The improvement of the quality of the foreground lighting of a tram significantly increases the safety and comfort of all urban street traffic users.

Opis:: Recent progress within the area of front lighting of motor vehicles makes it possible to implement some technical solutions in other types of vehicles. High quality of front lighting is a factor required not only in motor vehicles. The article shall present the current state of front lighting of trams and qualitative analysis shall be presented of currently used light beams. The emphasis put on the quality of motor vehicle projectors, their constant development and application ofnew kinds of light sources, as well as application ofadvanced systems ofautomatic light beam direction does not translate into application ofthese solutions in tram vehicles. Safe movement of a trach vehicle is conditioned by the quality and state of its main lighting. Appropriate distribution of a light beam plays a significant role in the perception of luminous sensations from a vehicle's foreground. It ensures a proper assessment of behaviour of other road traffic participants and conditions proper visibility from a tram driver's seat. The analysis of tram line lighting shall be conducted on the basis of real photometric measurement data with the use of calculation programme having an advanced model of foreground lighting of the vehicle at its disposal. Lighting recommendations shall be presented taking into account the characteristics of light beams used in trams

Tytuł:: Proposal of lighting requirements for lighting devices in adaptive front lighting system of trams head lights

Opis:: The paper presents the issues strictly connected with the scientific discipline of Transport, concerning the exploitation of lighting devices, reflectors and projectors being the fundamental devices for tram 's head lighting. The factor influencing the safety of a moving track vehicle is the quality and state of tram's head lighting. Appropriate light distribution within the area of tram's foreground plays a decisive role in the perception of luminous sensations by the tram driver. A properly shaped light beam conditions appropriate visibility from the tram driver's seat and facilitates correct assessment of traffic situations connected with the behaviour of other road traffic participants. The history of development of lighting devices for head lights used for trams has been discussed. The article proposes and discusses application of AFS system in trams particularly accounting for proposals of new lighting requirements for tram's head lighting devices. Particular attention has been paid to photometric requirements for projectors and reflectors of tram's head lights, presenting proposals for these requirements. After conducting a lighting analysis of currently exploited light beams it has been established that justification exists for using symmetrical light beams in the case of head, main and low beam lights. Introduction of three kinds of lights of dedicated light beams for low beam, main and curve lights is proposed.

The article proposes and discusses application of AFS system in trams particularly accounting for proposals of new lighting requirements for tram's head lighting devices. The author of the present paper justifies the need for implementing new solutions for lighting of tram's foreground in order to improve the quality of lighting taking into account various road traffic situations. For this purpose, new normative guidelines have been proposed allowing for assessment of lighting devices installed on trams, which directly influence the quality of tram's foreground lighting. Proposal for AFS system components for tram, measurement screen for examining projectors of symmetrical low beam lights, for examining projectors of symmetrical main lights, for examining the right projector of curve light and for examining the left projector of curve light are presented in the paper.
