Title: Quantifying the Effects of Activity Concentration at Airports on Public Transport Using an Iterative Reduction Procedure
Abstract: Airport locations are increasingly the place of non-aeronautical activities. This is driven by airport operators seeking non-aeronautical revenues and real estate investors attempting to profit from major airports as high value locations. The resulting higher densities lead to more travel to and from the location. Travellers induced by non-aeronautical activity are likely to behave different than those induced by aeronautical activity. Consequently, there are potentially not only more, but also more public transport prone travellers. This can improve the viability of operating high quality public transport services. However, as demand of the different traveller groups is likely distributed differently, it also needs to be studied whether the superimposed demand affects the peaking behaviour of travel demand in a beneficial, balancing, or negative, exacerbating, way. For the analysis, an iterative reduction procedure is proposed that begins with a network of highest quality services. Considering demand elasticity and minimum loads to viably operate a service, network elements are degraded and demand is recalculated iteratively until only viable services remain. This procedure is applied to a case study of Zurich, where large scale commercial activities and a public transport hub are located at the airport. It was found that the non-aeronautical development already contributes decisively to public transport use and without it, severe service reductions might be necessary. Furthermore, the compound demand distribution is more even than that of the individual traveller groups, resulting in a landside transport hub that can be operated more efficiently than facilities in conventional locations. Future growth of the airport location will increase this effect and further service expansions may become an attractive option. It is concluded that the high connectivity of airport locations is an opportunity to drive development patterns conducive to public transport use. In addition, airports can be efficient locations for transfer centres as there, if their locations are suitable, sustained high demand with less variation throughout a day allows for a better utilisation of services and facilities.2

Title: A Level-based Approach to Public Transport Network Planning
Abstract: This paper defines the concept of public transport network level and uses it to describe the performance and future improvement of Zurich's public transport system. A public transport level is a specific type of service designed to serve a particular market. Service is defined as a combination of vehicles, infrastructure and operating characteristics. A "pure" level is when the service is targeted specifically to one particular market. A "hybrid" level is when a service is targeted to serve several markets. Urban travel is generally described as three markets: short, intermediate and long distance trips. Consequently many cities have developed three-level public transport networks: surface buses and trams to serve short trips, rapid rail to serve intermediate trips, and regional rail to serve longer distance trips. Often, by design or for historic reasons, cities have additional levels, fewer levels and/or the levels that are not precisely matched to their markets. For example, two-level networks are often found in medium size cities. Their advantage is lower costs while their main disadvantage is a mismatch between transport mode and market that manifests itself in capacity limitations. Using the level concept to help analyze and plan public transport service is useful because it focuses attention on matching service qualities to markets. This paper uses this approach to analyze the success of Zurich's public transport system and to provide a structure for planning improvements that will be needed to meet rapidly increasing public transport demand. This approach could help other cities (re)design their public transport systems to be more attractive and efficient. More specifically, the approach could show how two-level public transport networks could be a viable option for medium sized cities and large cities with dispersed settlement patterns.2

Title: Effects of non-aeronautical activities at airports on the public transport access system
Subtitle: A case study of Zurich Airport
Abstract: Many planning authorities and airports study measures to increase public transport use for airport ground access and egress. At the same time, an increase in real estate development at and around airports is occurring, both due to airports seeking new revenue possibilities and other developers attempting to profit from high value locations. This paper considers non-aeronautical activities at large airports, largely commercial centres and transit hubs, as land uses that have the potential to improve the situation for operating public transport services. In order to assess potential benefits and disadvantages, four research questions are considered: (1) Can the additional travel volume reach levels at which it has a significant impact? (2) To what extent do non-aeronautical activities influence the public transport access system? (3) Is the resulting demand distribution better or worse regarding peaking behaviour? (4) Is there a potential for the resulting overall demand to bring about capacity shortages? A case study is conducted at the airport of Zurich, Switzerland, which finds that non-aeronautical activities in the direct airport vicinity have led to a situation where the operation of public transport services is much more viable due to overall higher passenger numbers and a more even distribution throughout the day. It is concluded that locating non-aeronautical activities at airports can, in addition to providing commercial benefits to developers, lead to a situation where improved public transport services become feasible.2

Title: Verkehrsqualität und Leistungsfähigkeit des strassengebundenen öV
Subtitle: Quality and capacity of public transport on streets = Qualité du trafic et capacité des transports publics routiers
Abstract: Für die Verkehrsqualitätsbetrachtung des öffentlichen Verkehrs wird die Betrachtungsweise - im Gegensatz zu den individualisierten Verkehrssystemen - auf zwei Akteure ausgeweitet: · Kunde: ergebnisorientierte, subjektive Bewertung -> Beförderungsqualität · Verkehrsbetreiber: prozessorientierte, technische Beurteilung -> Betriebsqualität/ Leistungsfähigkeit. Für die Beförderungsqualität und die Betriebsqualität/Leistungsfähigkeit werden für die folgenden Verkehrssysteme aufgrund von Literaturanalysen, bestehenen Richtlinien und Normenwerken, vorliegenden empirischen Untersuchungen, empirischen Neuerfassungen sowie Modellen repräsentative Richtwerte und Bemessungsverfahren für schweizerische Verhältnisse erarbeitet: · Strassenbahn, · (Trolley-)Busse im Linienverkehr und · Bedarfsbussysteme Da Bedarfssysteme naturgemäss bei sehr tiefer Nachfrage eingesetzt werden, weicht deren Betrachtung von den übrigen Systemen ab. Insbesondere die Aspekte des Ressourceneinsatzes und der Wartezeiten der Fahrgäste stehen hier im Vordergrund. Aufgrund einer detaillierten Literaturauswertung werden in einer ersten Phase relevante Parameter zur Beschreibung der Verkehrsqualität und Einflussgrössen auf die Leistungsfähigkeit für die drei obengenannten Verkehrssysteme bestimmt und die schon vorhandenen Erkenntnisse aus der Vorstudie SVI 2007/005 zusammengetragen, sowie allfällige Daten erhoben und ausgewertet. Auf dieser Grundlage werden in einer zweiten Phase einerseits Richtwerte und Bemessungsverfahren der Beförderungsqualität und der Betriebsqualität/Leistungsfähigkeit in Abhängigkeit der ermittelten Einflussfaktoren festgelegt und andererseits Abstufungen zur Verkehrsqualität erarbeitet. Aufgrund der Erkenntnisse werden Vorschläge für Bemessungsverfahren für die verschiedenen Systeme, Betriebsformen und Anlagen unterbreitet und Empfehlungen für die Normung zusammengefasst.2

Title: Airport cities and airport public transport access – demand balancing or peak exacerbation?
Subtitle: The case of zurich airport
Abstract: Many airports are adding non-aviation activities in an effort to diversify and become less dependent on direct air traffic revenues, creating so called "airport cities". As these generate an increase in traffic, the question arises how this influences the ground transport access system and if this can be used in strategies to achieve higher public transport mode shares. In the best case, the additional traffic follows a distribution that balances out the peaks created by the aviation induced travel and therefore helps create more even transport demand. This is especially critical for providing cost-efficient public transport services where service capacity cannot be adjusted very flexibly without sacrificing ease of use. In the worst case however, additional non-aviation travel demand would peak at the same time as aviation induced travel, thus increasing peak period travel demand. This would increase costs for peak period service without improving utilization during low-demand periods. This paper presents a generic framework for analyzing aviation and non-aviation transport demand, followed by a specific study of Zurich Airport. In this case, the non-aviation demand is distributed complementary to the aviation-induced demand but its volume is so high that it dominates the total demand curve. This means that the total travel demand is high enough to support a higher level of public transport service than could be operated economically if fed only by the aviation operations, and is one reason why Zurich airport's public transport mode share for air travelers is approximately 50%.2

Title: Calibration of a public transport performance measurement system for Switzerland
Abstract: Performance evaluation is fundamental to transport analysis and operations. This paper describes a quality evaluation framework based on level of service (LOS) developed for urban public transport in Switzerland. The framework focuses on four key indicators: on time performance, headway adherence, speed and passenger loads. The framework allows users to assess service quality at different levels by measuring the indicators at the single element level and aggregating scores over larger sets of elements. The number of indicators is relatively small compared to other frameworks, this makes the method easier to apply but also provides less detailed results. An earlier paper presented a conceptual approach for the framework. This paper extends that work by describing the approach in more detail and focusing on calibration of the LOS framework and application of the framework to a real example in Zurich. The research is part of a larger effort designed to develop a consistent multimodal LOS evaluation system for Switzerland. This system would include non-motorized traffic, public transport and road-based transport.

Title: High-Quality Public Transport and Promotion of Nonmotorized Transport – Compromise or Complement?
Subtitle: Analytical Approach Assessing Conflicts
Abstract: Public transport is a very efficient way to handle large traffic flows in urban areas. At the same time, and especially in Europe, non-motorized transport is being promoted as a further, environmental friendly and healthy way of urban mobility. This includes the introduction and extension of separate lanes to increase safety and convenience of bikers and pedestrians. However, most cities have limited space for expanding streets and roads which can lead to a conflict between the different uses. It is critical to clearly understand the impacts of these changes on public transport. In this research, a quick assessment model was developed that analyzes the impact of changes to roadway design and policy that can affect public transport services. It was developed for Zurich's public transport operator Verkehrsbetriebe Zürich (VBZ) to help them quickly assess changes such as the elimination of separate right-of-ways or the introduction of slow zones and also to help illustrate the impacts of these changes to non-technical audiences. The model uses a series of analytical calculations to analyze the main relationships between key public transport inputs and outputs. It was validated using data from Zurich's tram and bus network. The case studies examine the influence of reducing separate right-of-ways, the expansion of 30 km/h zones and changes to stop distances on public transport operations.

Title: Informationstechnologien in der zukünftigen Gütertransportwirtschaft
Abstract: Ausgehend vom dynamischen Wachstum der Transportströme steht die Schweiz als eines der wichtigsten Transitländer Europas vor grossen Herausforderungen. Ergänzend zum zeit- und kostenintensiven Ausbau der Infrastruktur müssen daher auch die weiteren Möglichkeiten zur Kapazitätsverbesserung und zur verbesserten Nutzung vorhandener Kapazitäten ausgeschöpft werden. In diesem Sinne wurden aktuell vorhandene Prinzipien der IT-Anwendungen im Güterverkehr auf den drei Nutzungsebenen Infrastrukturbewirtschaftung, Prozesskettenbetreiber und unternehmensintern hinsichtlich ihrer Wirkungen untersucht und bewertet. Darüber hinaus wurden erwartete Trends und Entwicklungen im IT- Sektor mit einbezogen. Die Wertung der IT-Funktionalitäten / Funktionen orientiert sich einerseits an den Nutzungsebenen sowie andererseits an den Strategien zur Verkehrsverlagerung, Verkehrsvermeidung und Verkehrslenkung/-steuerung.

Title: Development of a Public Transport Performance Measurement System
Abstract: Accurate performance measurement systems are important for all businesses including public transport. The importance of such system will grow with the advent of liberalization in the European transit sector, that is, the opening of transit service provision for tendering, as service provision contracts will require agreed-upon measures for service provision contracts and the controlling thereof. This paper describes research on developing a public transport level of service (LOS) standards framework for Switzerland. The standards framework is intended to reflect influences on capacity and operational quality in urban road-based transit and relies on four main measures; speeds, passenger loads, on-time performance and headway adherence. This paper outlines the selection of specific measures for evaluating public transport LOS and the proposed framework. The framework provides a consistent method for evaluating public transport LOS on all levels of analysis from single elements (e.g. bus stops) to network analysis. The paper also describes how information from automated on-board data collection systems can be used for detailed service analysis. This calibration procedure is illustrated in an example from the Zurich public transport system. Finally, the paper describes future development of the approach, challenges faced (especially with respect to selection and filtering of relevant data) and conclusions. While the proposed LOS framework is being prepared for Switzerland, the experience and approach described in this paper should help others developing and improving performance management systems for public transport.

Title: Mit Bus und Tram durch dichte Räume
Abstract: Ohne den öffentlichen Verkehr ist die Mobilität in den schweizerischen Agglomerationen nicht sicherzustellen. Meist kommen Tram- oder Bussysteme zum Einsatz. Die Entscheidung zugunsten eines Trams fällt oft aufgrund von dessen Vorteilen hinsichtlich Kapazität, Pünktlichkeit und Wahrnehmung durch die Nutzerinnen und Nutzer. Doch auch ein hochwertiges Bussystem ist als Alternative zu prüfen.

Title: Small agglomerations, high transit use
Subtitle: Transportation system deployment and land use in Switzerland
Abstract: Land use is widely recognized as a key factor in determining the success of public transport and the type of transport services that should be provided to a specific area. However, much research on the links between land use and deployed modes of transportation is either old or limited to specific regions. The goal of this research was to evaluate the deployment of urban transport systems throughout Switzerland to develop guidelines for determining which urban transport modes 'should' be deployed for given development patterns. Switzerland is a good place to consider this question since public transport usage is relatively high and transportation systems are quite well developed – possibly in part due to a very positive public perception of transit. This research considers the land use characteristics for all Swiss agglomerations, the available modes of transportation and the use of transport modes. Characteristics studied are population size, population and land use density, geographical area, shape of the region and its location. An analysis of these data is performed and it is found that land use density, population size and density, spatial size and shape are especially important in determining which urban transport modes are provided. This information is used to define recommendations for application of given transport modes. Given today's heightened interest in rail and other high quality and capacity public transport services but scarce financing, these findings are helpful in urban transport decision-making processes.2

Title: Public Transport Capacity and Quality
Subtitle: Development of an LOS-Based Evaluation Scheme
Abstract: Public transport providers and government agencies have an interest in viable measurements to evaluate and compare public transport services. With the advent of liberalization in the transportation sector, this interest becomes a requirement as both service providers and service purchasers need agreed-upon measurements for the design of service provision contracts and realization thereof. The objective of this research is to develop standard values and measurements for quality and capacity in roadway-based public transport including tramway and bus services. The focus of the evaluation is primarily on capacity and operational quality, with quality in terms of comfort being considered as far as it impacts capacity. This paper describes the evaluation scheme in development for this purpose. Conceptually, capacity is viewed as the result of a theoretical maximal threshold value that is reduced by a number of limiting influences arising from the operation in the oftentimes volatile environment that the roadways and passenger behavior are. Based on this, capacity and quality are measured using spatial and temporal indicators. The measurements can be taken to evaluate a transit system at the levels of a single element, e.g. a single bus stop, a set of elements, such as a route or route segment or the whole transit system. Once calibrated, this evaluation scheme may serve as a tool to evaluate transit service operations.
