Urban Public Transport

The demand of transport grows along with road traffic. Congestion costs 1% of the GDP of European Union (European Union 2014) and also causes significant emissions of carbon dioxide and other pollutants. This problem could be solved by transfering a part of passengers from private modes of transport to the public transport. But the essential condition is a sustainable development which means the accessibility on equal terms. Therefore, attention to the focus group – people with movement impairements, is neccessary. Since even under ideal conditions some of those people will not be able to use the ordinary public transport services, a special transportation service, called paratransit, should be offered. In this paper the parameters of paratransit as well as their variations are analyzed. Also the wider application possibilities are considered. The aspects of integration of paratransit into the existing system, pottential barriers for the integration and conditions for the integration are highlighted. The main purpose of this paper is to formulate the scenarios for the integration of paratransit into the existing public transport system based on the analysis of the scientific literature and the best practices, which could be used to form a policy of improving the accessibility of the public transport for people with movement impairments. Transporto paklausa nuolat auga, o kartu su ja ir kelių eismo intensyvumas. Spūstys Europoje kasmet sudaro apie 1 % jos BVP (Europos Sąjunga 2014), dėl jų išmetama daug anglies dioksido ir kitų nepageidaujamų teršalų. Ši problema miestuose gali būti sprendžiama perkėlus dalį keleivių iš privataus į viešąjį transportą. Tačiau labai svarbu, kad vykdomi projektai atitiktų tvarios plėtros principus, pagal kuriuos numatomas viešojo transporto prieinamumas lygiomis teisėmis. Todėl būtinas dėmesys tikslinei žmonių grupei – žmonėms, turintiems judėjimo apribojimų. Kadangi dalis tų žmonių netgi esant idealioms sąlygoms negalės naudotis tradiciniu viešuoju transportu, jiems yra būtina specialioji transporto paslauga, vadinama paratransportu. Šiame straipsnyje yra išskiriami paratransporto paslaugos parametrai, jų variacijos. Taip pat analizuojamos platesnės šios paslaugos pritaikomumo galimybės. Išskiriami transportinės paslaugos integravimo į esamą viešojo transporto sistemą aspektai bei potencialūs barjerai ir sąlygos paratransporto paslaugai įdiegti. Šio straipsnio tikslas – remiantis mokslinės literatūros ir gerosios patirties analize suformuluoti paratransporto įdiegimo į veikiančią viešojo transporto sistemą scenarijus, kurie gali būti taikomi formuojant viešojo transporto prieinamumo žmonėms, turintiems judėjimo apribojimų, tobulinimo politiką.

This paper shows the results of an in-depth techno-economic analysis of the public transport sector in a small to midsize city and its surrounding area. Public battery-electric and hydrogen fuel cell buses are comparatively evaluated by means of a total cost of ownership (TCO) model building on historical data and a projection of market prices. Additionally, a structural analysis of the public transport system of a specific city is performed, assessing best fitting bus lines for the use of electric or hydrogen busses, which is supported by a brief acceptance evaluation of the local citizens. The TCO results for electric buses show a strong cost decrease until the year 2030, reaching 23.5% lower TCOs compared to the conventional diesel bus. The optimal electric bus charging system will be the opportunity (pantograph) charging infrastructure. However, the opportunity charging method is applicable under the assumption that several buses share the same station and there is a “hotspot” where as many as possible bus lines converge. In the case of electric buses for the year 2020, the parameter which influenced the most on the TCO was the battery cost, opposite to the year 2030 in where the bus body cost and fuel cost parameters are the ones that dominate the TCO, due to the learning rate of the batteries. For H2 buses, finding a hotspot is not crucial because they have a similar range to the diesel ones as well as a similar refueling time. H2 buses until 2030 still have 15.4% higher TCO than the diesel bus system. Considering the benefits of a hypothetical scaling-up effect of hydrogen infrastructures in the region, the hydrogen cost could drop to 5 €/kg. In this case, the overall TCO of the hydrogen solution would drop to a slightly lower TCO than the diesel solution in 2030. Therefore, hydrogen buses can be competitive in small to midsize cities, even with limited routes. For hydrogen buses, the bus body and fuel cost make up a large part of the TCO. Reducing the fuel cost will be an important aspect to reduce the total TCO of the hydrogen bus.

As an extension of public space, the public transport system in modern society is an arena for cross-group interactions. Uncovering social segregation in public transport space is an essential step in shaping a socially sustainable transport system. Based on 2011 origin–destination flow data for London, we simulate the working flows between each pair of connected tube stations for every occupation with minimised transfer times and travelling hours and calculate the multi-occupation segregation index for all tube stations and segments. This segregation index captures the density and diversity aspects of the working population. The results demonstrate that segregation levels vary significantly across stations, lines, and segments. Transfer stations and tube segments in the city centre do not necessarily have lower levels of segregation. Those stations or segments close to a terminus can also be socially inclusive, e.g., Heathrow. Victoria is the line with the lowest levels of segregation, and Green Park is the most socially inclusive station during commuting peaks. The proposed mapping approach demonstrates the spatial complexity in the social performance of the public transport system and provides a tool for implementing relevant policy with improved precision.

Last Mile

Bicycle Sharing Systems (BSSs) are exponentially increasing in the urban mobility sector. They are traditionally conceived as a last-mile complement to the public transport system. In this paper, we demonstrate that BSSs can be seen as a public transport system in their own right. To do so, we build a mathematical framework for the classification of BSS trips. Using trajectory information, we create the trip index, which characterizes the intrinsic purpose of the use of BSS as transport or leisure. The construction of the trip index required a specific analysis of the BSS shortest path, which cannot be directly calculated from the topology of the network given that cyclists can find shortcuts through traffic lights, pedestrian crossings, etc. to reduce the overall traveled distance. Adding a layer of complication to the problem, these shortcuts have a non-trivial existence in terms of being intermittent, or short lived. We applied the proposed methodology to empirical data from BiciMAD, the public BSS in Madrid (Spain). The obtained results show that the trip index correctly determines transport and leisure categories, which exhibit distinct statistical and operational features. Finally, we inferred the underlying BSS public transport network and show the fundamental trajectories traveled by users. Based on this analysis, we conclude that 90.60% of BiciMAD’s use fall in the category of transport, which demonstrates our first statement.

The Difference

You have crossed that awkward, deeply uncomfortable, sometimes shameful social state of being without a car. I mean in some countries where the public transport system works, not having a car is no big deal. But you are in Nigeria, where public transport is living hell, and owning a car can be the difference between life and social death....
