In public transport, especially in bus services, the number of passengers decreases, largely because individual car transport are able to provide a higher quality passenger transport. Passengers choose the mode of transport based on the shortest travel time. This is why the share of individual car transport is growing, especially in suburban bus transport, but also in urban transport in smaller towns. Given that the travel time is more important for a traveler compared to the cost of transport, the aim of this contribution is to verify the hypothesis that shorter stopping times are needed for vehicles with a smaller capacity. When verifying the hypothesis, the authors will also address the issue of the impact of the number of vehicle doors and total capacity on the total travel time of the passenger.
