    Light rail lessons learnt worldwide

    Light rail has several potential benefits, both from a mobility and urban quality perspective. However, not all light rail systems are a success and there is much debate about the costs. Niels van Oort, co-director of the Smart Public Transport Lab at TU Delft, investigated 61 cases worldwide and will share his findings on the wider benefits of light rail.

    Operations of zero-emission buses: impacts of charging methods and mechanisms on costs and the level of service

    To limit global warming and strive for more liveable and sustainable cities, innovative zero-emission buses are on the rise all around the world. For now, only trolley, battery and fuel-cell electric vehicles can be classified as (on the pipe) zero-emission vehicles. Different charging methods, including different charging systems and power, are available to charge battery electric vehicles. However, scientific literature focused on the operation and charging scheduling of electric vehicles is scarce.
    In this study, a comparison of different applied charging methods for electric buses is obtained. A new ZE-bus station simulation method is developed to assess charging methods and charging regulations with regard to their impacts on costs and level of service.
    The shift to zero emission bus transport is meant for achieving more sustainable and liveable cities. However, this research concludes that this is involved with higher costs and passenger disturbances. The investment costs increase substantially. Benefits of electric operations, including vehicle propulsion cost savings up to 70 percent, are not able to compensate these high investments. (Slow) depot charging offers opportunities for operations on short distance lines. The depot location should be close to a bus station and additional fleet is required. In order to prevent fleet overcapacity, vehicles should be recharged with high charging power along the line, preferably at combined bus stations and terminals in order to prevent charging related delays. Dynamic/In-motion charging – still in its infancy stage yet – offers opportunities to prevent these delays due to combined charging and operation time.

    E-bussen laden zorgt voor nieuw spanningsveld op busstations

    Om de bijdrage van transport aan de opwarming van de aarde te minimaliseren en de leefbaarheid in onze woonomgeving te verbeteren groeit de wereldwijde vloot zero-emissiebussen snel. Zero emissiebussen dragen bij aan een duurzame en leefbare woonomgeving. Uit dit onderzoek blijkt echter dat inzet van zero emissiebussen ook gepaard gaat met hogere kosten en meer onbetrouwbaarheid van de dienstregeling voor de reiziger. De investeringskosten zijn hoger dan bij ‘oude vertrouwde dieselbussen’. Exploitatie met elektrische bussen is tot 70% goedkoper dan dieselbussen, maar deze winst is niet genoeg om de toename in investeringskosten te neutraliseren. Tot op heden is de capaciteit van batterijen onvoldoende om bussen van begin tot einde dienst zonder tussentijds laden in te zetten. Tussentijds laden in de garage kost echter tijd en extra voertuigbewegingen en is daarom onwenselijk. Om die reden is het aan te raden batterijen te laden op busstations.

    Improving railway passengers experience: two perspectives

    This paper describes two perspectives to improve the passenger experience. The passenger satisfaction pyramid is introduced, consisting of the base of the pyramid (dissatisfiers) focusing on time well saved and the top of the pyramid (satisfiers) aiming at time well spent. The challenge in planning and design of public transport services is to find the most efficient (set of) design choices. Depending on the context this might either mean focusing on the top or on the bottom of the pyramid. We found that influencing and enhancing the qualities of the satisfiers is far more important than traditional studies showed us. For stations, regression analyses show that dissatisfiers are responsible for explaining almost half of the total score of the station and satisfiers are responsible for the other half of the scores passengers give for the station. We still have to put a lot of energy in getting the basics right, starting in the planning phase, but then we are not allowed to lean back. We have to keep investing in qualities like ambience, comfort and experience which makes the customers truly happy at the end of the day.

    Van B naar Anders

    Op woensdag 30 mei organiseerde de Rli naar aanleiding van zijn advies een symposium. Tijdens dit symposium is het advies toegelicht en met betrokkenen uit de mobiliteitswereld besproken. Daarbij wordt stilgestaan bij de toekomst van mobiliteit en infrastructuur, de bestuurlijke praktijk en bij innovatie en verduurzaming van ons mobiliteitssysteem.

    The wider benefits of high quality of public transport for cities

    The full value of public transport is often underestimated. The 5E framework, consisting of effective mobility, efficient city, economy, environment and equity supports assessing and quantifying this value. This paper presents the framework and a wide selection of sources illustrating the wider benefits of high quality of public transport for cities.

    Trambonus hoort in strategische planning

    Kiezen we voor de bus of voor de tram? Bij de introductie van nieuwe ov-lijnen is de systeemkeuze altijd een belangrijk discussiepunt.

    Wat is de waarde van Openbaar Vervoer?

    De waarde van openbaar vervoer wordt vaak te beperkt in beeld gebracht. Het draait vaak alleen om kosten van infrastructuur en exploitatie. Waarom eigenlijk? De waarde van ov is meer dan alleen de vervoerwaarde. 5xE is een betere manier om het ov op waarde te schatten voor Effectieve mobiliteit, een Efficiënte stad, Economie, milieu (Environment) en sociale cohesie (Equity).

    International rail summit 2016: Big Data and rail

    Big Data also enter the railway industry. Board computers, passenger smart cards and cell phones provide valuable data to enhance design of networks and timetables. Big Data supports the improvement of transport models and cost benefit analyses (CBAs). An example of success was the approval of a new light rail in Utrecht, the Netherlands. It was not common use to consider reliability benefits explicitly, but in this case they were responsible for the positive cost benefit ratio.

    Robustness of multi-level public transport networks: A methodology to quantify robustness from a passenger perspective

    Despite the importance of robust public transport networks, this topic has not been considered from a full passenger perspective yet in scientific literature and practice. To our best knowledge, this study is the first in which both exposure to large, non-recurrent disturbances and impact of these disturbances are analysed in a systematic and realistic way. Contrary to single-level network perspectives, we considered the integrated, total multi-level public transport network which remains available when a disturbance occurs. We developed a new methodology to identify the most vulnerable links in the multi-level public transport network and to quantify the societal costs of non-robustness of these vulnerable links. Besides, applying our methodology enables quantification of the robustness benefits of robustness measures, next to the costs of such measures. Therefore, our methodology can support and rationalize the decision-making process of public transport operators and authorities regarding the implementation of different robustness measures.
