PTOs (Public Transport Operators) in Europe have a significant influence on industry, which causes new challenges for automotive, peculiarly for bus manufactures. The first step in order to meet the requirements was to develop buses, which have marginal environmental impact in the place of operation. Behavior of the driver, as the most unpredictable factor, is causing various energy consumption and harmful emission [1]. This aspect can be reduced using driver- assistance systems. Adapting ADAS (Advanced Driver-Assistance Systems) and self-driving technologies into vehicles will lead not only to ecological aspects, but also to road safety and improvement of traffic flow. In recent years the number of experienced drivers have noticeably decreased [2]. Nowadays, the vast majority of bus drivers and PTOs indicate the need to develop and implement systems supporting maneuvering. Every ADAS and autonomous system should be founded on well-adjusted components. This paper will describe the methods of evaluating the matching devices for each level of autonomy. Furthermore, market analysis and comparison of distinctive ADAS and autonomous equipment will be presented [3]. Owing to the scientific research gained from cooperation of AGH Science and Technology University, Poznań University of Technology and Solaris Bus & Coach experience is leading to development of ADAS. Analysis of necessary sensors in city e-buses, including case study, will be presented in the paper.
