Bus lines can target distinct profiles of passengers. For example, bus lines serving university areas need higher capacity and faster buses to serve young people at rush hours. Contrarily, during off-peak hours, bus lines serving market areas might require buses with more seats and a higher level of comfort.
Applying the same layout to all bus services is not the answer. Differences in terms of age, physical abilities and journey expectations should be taken into account to design bus layouts (e.g. seat arrangements, size and position of doors) as well as bus stops to optimize the flow of passengers on board and during boarding and alighting.
