The paper presents the application of the Multiple Criteria Decision Aid/Making (MCDA/MCDM) methodology in the assessment of the development of different scenarios for an urban public transportation system (UPTS). This methodology allows considering several conflicting objectives and performing the evaluation process in a comprehensive manner. This approach also corresponds to the holistic philosophy: different aspects (economic, technical, social etc.) and interest groups – stakeholders (operators, passengers, city government etc.). The MCDA/MCDM methodology is specifically customized to the real life case study – urban public transportation system in the city of Cracow (Poland). A family of 10 criteria is proposed to evaluate several solutions (W) for a UPTS in terms of their usefulness and attractiveness for different stakeholders. These criteria take into account: travel time and standard, effectiveness of the fleet use, environment friendliness, the level of integration and reliability of the UPTS, safety and security, the profitability and availability of the UPTS, investment costs. Considering the possible solutions, the 6 alternatives were designed heuristically and compared with the current state (denotation of alternative W0). Based on the analysis, for the final considerations compared with the current alternative, 7 new solutions of the integrated urban public transportation in Cracow were adopted, denoted as: W1 (bus/rail alternative: integration of high-speed agglomeration rail with bus transportation), W2 (rail/tram/bus alternative: integration of high-speed agglomeration rail with tram and bus transport system), W3 (alternative with the underground: integration of the underground with high-speed agglomeration rail and with tram and bus transport system), W4 (tram/rail alternative: integration of high-speed agglomeration rail with tram transport), W5 (Tram alternative: integration of tram transport with bus transport), W5A (tram alternative: sub-alternative to the alternative W5, integration of tram transport), W6 (dual-mode tram alternative: integration of dual-mode tram transport). The variants of the scenarios for the urban public transportation system were generated by VISUM computer macro-simulation software. The computational experiment was carried out with the practical application of different Multiple Criteria Decision Aid/Making methods: AHP (Expert Choice program) and Electre III (software package Diviz).

The sustainable development of transport is fostered by innovations. To implement innovations, the European Commission issues different regulations, programs and initiatives and the European Transport Policy has a significant impact on transport policy in the member states. At the same time, transport policy is dynamic and requires new solutions that will allow the planned goals to be achieved. In this context, it is important to analyze the effectiveness of the current innovation policies, and to create recommendations for future actions that bring innovations to the market. This article concerns the subject of innovation policy in the transport sector. It illustrates the possibility of applying one of the methods of the multiple criteria decision aid, i.e., the simple additive weighting (SAW) method to assess the European Union (EU) and national policy measures in surface transport in terms of their influence on the market take-up of innovations. The use of this method allows for the analyzed policy measures to be contemplated in terms of various criteria and to identify those that best meet the adopted criteria, and thus those that could contribute the most to the stimulation of innovation. The article focuses on the method itself, indicating its flexibility and ease of use, while the analyzed collection of policy measures constitutes only the background of the deliberations.

Nowadays population ageing is one of the most important challenge in the world. In this paper basic definitions related to old age and population ageing were presented. Predictions of population growth in several dozen of years in different world regions were described in detail. Predictions taking the elderly people into account were emphasized. Based on available data, demographic changes in chosen EU countries were compared. In addition statistic data related to population in Poland and increase in the number of elderly people in several Polish regions were presented. The growth of elderly people in population influences many aspects of urban life. Statistic research shows that most of elderly people, despite of good mental fitness, meet some restrictions, that make their life in cities more difficult, especially including travelling and achieving basic travel purposes. Thus it is necessary to get knowledge on basic elderly people’s needs, as it allows to design cities which are friendly to seniors. The modal split in the elderly peoples’ journeys in EU countries was presented on the basis of the literature review. Also elderly people’s mobility needs as well as the most important factors influencing seniors’ mobility were identified.
