“…2019 and 09.10.2019 [2]. The average length of the EKO 1 line is 7995 m. Depending on directions, the length of the route in the direction "A" is 7477 m, where there are 15 stations with an average inter-station distance of 534 m. In the direction "B", the length of the route is 8513 m, where 17 stations are positioned with an average inter-station distance of 532 m. Figure 2, shows the topography of the terrain with the elevations of the stations [3].…”

One of the most important features of an electric bus (E-bus) is the ability to recover electricity generated during the braking and deceleration phase of the vehicle's movement. The specificity of the bus operation in urban transport is reflected in the dynamic mode of vehicle's operation, especially in terms of frequency and intensity of acceleration and braking. Recovered electricity during the braking and deceleration phase of E-bus drive is determined by the performance of the drive electric motor, the strategy choice (algorithm) for regenerative braking control, driving cycle, terrain configuration, the ability of the supercapacitor to receive as much electricity as possible and the driving style of the driver. The researches of the electricity recovered on the EKO 1 line was performed in 2018 and 2019. The time of year has been chosen when heating and air-conditioning systems were not used or minimally used only in certain periods of the day, in order to more realistically look at the effect of the achieved recovery and the impact on the energy efficiency of the E-bus. The measured values of the supercapacitor voltage, the discharge and recuperation current of the supercapacitor and the SOC (State of Charge) values were taken from the SD memory card BMS (Battery Management System) of the control unit that performs data acquisition from the V-CAN of the E-bus. The value of the recovered electricity, under the assumption that the regenerative braking system is used correctly, is mostly affected by the terrain configuration, i.e. the presence of inclined sections.

“…Supercapacitors can be charged rapidly, reducing the time needed to prepare to resume operation. The concept of E-buses with the pantograph charging system on the termini completely meets the conditions of exploitation in terms of electricity supply, the daily autonomy, and the passengers' transport demands [31]. E-buses also eliminate infrastructure needed for a constant grid connection and allow routes to be modified without infrastructure changes compared to a Trolleybus.…”

City transport causes the biggest part of road transport emissions. Besides, by engaging mainly fossil fuels in the city transport, we are responsible for air pollution in urban areas. On the other hand, passengers transport (private and public, individual and mass) may contribute substantially to reduce the negative impact on the environment by application of alternative fuels and declining of the use of fossil fuels. The main alternative fuels for drive systems in transport are the following: electricity, hydrogen, and biofuels. Synthetic fuels are option as a technology. Some of them are very effective but too expensive technologies. Another way is introduction of flexible transport (from door to door, on demand, etc.) which application enables to decrease the number of cars in urban centers to avoid congestions and the negative impact on the environment. This paper points out that public transport has a special role in the process of decreasing fossil fuel dependence, and the necessity for rapid alternative technology implementation, as well as development of the public transport system itself. Proposed is the introduction of public passenger transport from door to door that offers a comfort comparable to personal cars (specifically for handicapped persons) and helps to lowering congestions on the roads.
