Titel: Vehicle ownership and usage in Switzerland: the role of micro and macro-accessibility
Kurzbeschreibung: This study investigates the role of built environment and accessibility on vehicle ownership and usage in Switzerland. To characterize the urban structure we make a distinction between micro- accessibility and macro-accessibility. Micro-accessibility is derived from an extensive online points of interest database and the walking time to these destinations. From the calculated micro- accessibility, a diversity and destination index is constructed. After controlling for household income, license ownership and household composition, built environment and accessibility significantly influences vehicle ownership and usage. Diversity of nearby destinations is more than important the number of destinations for both vehicle ownership and usage. Public transport accessibility plays a more important role in moderating vehicle ownership than in moderating vehicle usage for households owning a car.2

Titel: The role of location in residential location choice models
Untertitel: A review of literature
Kurzbeschreibung: Geospatial data available to researchers has increased tremendously over the last several decades, opening up opportunities to define residential location in multiple ways. This has led to a myriad of variables to define "location'' in residential location choice models. In this paper, we propose a common classification for location variables and categorize findings from a wide range of studies. We find similar preferences but different measurement methods and market segments for locations across different study regions. Recent studies consider the residential unit as choice alternative, making it possible to include a detailed description of the built environment. However, these studies are still limited in number and the inclusion of socioeconomic environment is more common. Transport land-use models can benefit from the inclusion of points of interest, such as schools, network distances, and the distance to previous locations. For the results of location choice models to be transferable to different disciplines, and avoid multi-collinearity, it is necessary to present different model specifications, including variables of interest in different disciplines.2

Titel: Evaluating novel and traditional survey methods for the construction of a behavioral founded walkability index
Kurzbeschreibung: Transportation planners have traditionally focused on different aspects of motorized transport. More recently, the importance of walking is being realized. Not only does every public transport trip start and end with a walking journey, walking as a main mode can reduce the number of motorized trips and reduce the accompanying negative externalities, such as road congestion, emissions and public transport overcrowding. Additionally, it has social and recreational value, and promotes physical and mental health (Southworth, 2005). For walking to be considered as a main mode, with the attractiveness of walking being dubbed walkability, several prerequisites are necessary. For instance, Speck (2012) puts forward that for a city to be walkable several prerequisites should be met. A walk should be useful (e.g. mixed use), safe, comfortable and interesting. In addition to this qualitative approach of describing walkability, approaches to quantify walkability have emerged. Walk Score, and other indices for walkability proposed so far are mostly ad-hoc, somewhat informative and refer generally to the closest amenities/public transport stops and the existing network structure. The weights of the attributes of the indices are generally arbitrary and do not reflect the independently measured preferences of the users and residents. Furthermore, they usually employ beeline distance measures instead of pedestrian network distances and do not include design attributes such as the layout of sidewalks, noise and speed level of traffic or street width, which are very relevant for actual planning decisions. As outlined, walkability consists of more than the mere presence of a sidewalk; it consists of both the quality and topology of the walking environment and how pedestrians' evaluate those characteristics. In this study we aim to formulate a behavioral founded walkability index, which incorporates pedestrian's preferences and design attributes. In order to calculate a walkability index, both the walking environment will be mapped and pedestrians preferences will be estimated with a discrete choice models. In the paper we will present our experiences and outcomes of measuring users' preferences of the walking environment in two districts in Singapore, in total measuring approximately 4 by 4 kilometers. The study will be carried out between January and July 2014 and will use three approaches: detailed mapping of the pedestrian network and description of destinations, analysis of reported/tracked walks indoors/outdoors (revealed preference) and of stated choice experiments. With the revealed preference approach, we aim to measure users' preferences by means of their route choice and destination choice. In the technology enabled approach 250 individuals, quota sampled based on age, gender and main mode used will be asked to install a smartphone application, making it possible to track individuals by means of GPS and WiFi spots. The survey area consists of high rises, indoor and underground pedestrian throughways. First tests however have shown this built environment can pose challenges for pedestrian position tracking by a combined GPS / WiFi approach, especially as we are not only interested the road being traversed, but also which side of the road and which crossings are used. Therefore, a second, traditional approach will be pursued additionally: random pedestrians will be followed by research assistants, and their origin, destination as well as traces and intermediate stops, will be noted, in addition to person characteristics, such as age category and gender. Based on the observed routes, choice sets will be generated and route choice models will be estimated. In the stated preference survey, the same 250 individuals will receive two different SP experiments, focusing on route choice (link properties, intersection characteristics) and destination choice by type of destination. This paper will focus on several aspects of the walkability study of relevance, namely: - The experiences with using combined GPS / WiFi in a dense urban environment; - Differences in data quality and resulting route choice models using GPS / WiFi trackers and 'traditional' following of individuals; - The comparison of behavioral parameters concerning walkability based on revealed preference respectively stated preference data.2

Titel: Embracing Walkability
Untertitel: How planning for pedestrians will lead to an alternative urban model
Kurzbeschreibung: Walking is not only a viable mode of transport to reach key amenities of daily life, it has positive effects on our health, increases public security, and is an activity of sheer pleasure in its own right. However, walking is only possible if the urban fabric and transport infrastructure is in place to support it. Given these advantages, one might wonder why most cities have gradually neglected the needs of pedestrians while constantly improving conditions for individual motorised traffic. This article outlines why transport planning models neglected to account for pedestrian movement, and how ignoring this factor in decision-making helped forming a vicious circle of building more roads to serve an ever increasing demand for cars and motorcycles. It also presents the initial results of a research roadmap with the goal to develop software tools for the evaluation of walkability to be applied for analysis and planning.2

Titel: Pedestrian and transit accessibility on a micro-level
Untertitel: Results & challenges
Kurzbeschreibung: In this paper we connect two notions of accessibility which are more often than not consid- ered separately: pedestrian accessibility and transit accessibility. We move away from the notion of zonal accessibility. Two pedestrian networks are compared to a base-line scenario considering Euclidean distances for a large metropolitan area in which each individual building is considered to be an activ- ity opportunity. It is shown that pedestrian accessibility to jobs differs when pedestrians distances are approximated with different networks. Stop-to-stop public transport travel times are extracted from an agent-based simulation of public transport smart card data. The effect of less than optimal connections to transit to the pedestrian network, a local measurement, can be seen when calculating the accessibility to all destinations in the city. We suggest to move away from Euclidean based distance analyses. Limi- tations can be found in the data available; the connection of buildings to the network becomes important as does the inclusion of pedestrian crossings. For an inclusive accessibility measure it will be necessary to calculate generalized costs for pedestrians and generate different pedestrian networks reflecting the limitations of different user groups.2

Titel: Measuring Location in Residential Location Choice: An Empirical Study on the Canton of Zurich
Kurzbeschreibung: In transportation and land-use research, discrete choice models have become a common method for assessing the value or utility of discrete alternatives for an individual choice-maker and have led to the simulation of land-use developments on a microscopic level. Discrete location choice models represent relocation behavior in those simulations and generally implement three groups of variables, representing attributes of the alternative, the decision-taker and the location. With the growing availability of spatial data on a disaggregated level, a large number of location variables have been reported in these models, which reduces their comparability and their transferability to other study areas. To address this limitation, Schirmer et al. (2012) classified location variables and proposed a common set of attributes as an initial setup. In this paper, we explore the impact of these attributes on residential location choice in the Canton of Zurich.2

Titel: Towards comparability in residential location choice modeling - a review of literature
Kurzbeschreibung: With the availability of disaggregated spatial data, residential location choice models have become more and more diverse in the hypothesis tested. This reduces the comparability of the main findings in different studies, although one might expect a comparable human behavior for comparable study areas. In the paper we review recent literature of the residential location choice models on a disaggregated level, in order to conclude in a set of variables recommended for use in models and simulations.

Titel: Decision support tools in transport planning
Untertitel: From research to practice
Kurzbeschreibung: With the progress in transport demand modelling from aggregated, static and zone-based assignment models to fully dynamic agent- and activity-based transport simulations, the scope of data that needs to be collected, managed and maintained has changed dramatically. Furthermore, the type of analyses as well as potential analysts have changed. Whereas traditionally transport modelers would analyze data and create static maps, pre-defined graphs and tables we envision other end-users: transport authorities, architects, policy-makers and the service industry. These analysts can utilize a decision-support tool, based on the output of an agent-based model as well as analyze their own datasets and fully analyze spatial and temporal agent behavior without requiring continuous support from a transport modeler. In this paper, we present a framework of a decision support system designed to enable analysis of the wealth of information provided by agent-based transport demand models, travel diary surveys and automatically collected data on transport infrastructure usage. We present a practical application of the framework using it for analyzing the MATSim model of Singapore along with the Household Interview Travel Survey and public transport smart card transaction data. At the time of writing, the status of presented applications is only preliminary as not all necessary dataset and interfaces are yet fully developed, but the presented case-studies give already a very good idea about the potential scope and functioning of the decision support system. For future work, we envisage stakeholder workshops to better understand their diverse requirements and jointly refine what type of questions the decision support system should support to answer and adapt it accordingly.

Titel: Accessibility on a micro-level
Untertitel: A closer look at pedestrian routing and network generation
Kurzbeschreibung: The main purpose of this paper is to investigate ways to determine realistic pedestrian distances from an origin to a destination and to calculate geographic extents based on pedestrian distances. Pedestrian movement and routing research employs a range of methods, requiring different types of data. Pedestrian movement is employed on the microscopic level. Research towards pedestrian networks has focused on generating sidewalks from different types of data sources in large areas. In pedestrian movement and network generation research generalized costs for pedestrians have not been investigated for different user groups. We take methods from movement research and investigate the possibility to employ this on a larger scale for routing purposes. Network generation methods and data sources are compared with each other and ground-truth. For future research we envisage a hybrid approach combining a grid for certain areas with a backbone of sidewalks and different link costs for different user groups.

Titel: Reviewing measurements in residential location choice models
Kurzbeschreibung: With the increase of the availability of disaggregated data, the modelling of residential location choices on a disaggregated level, has recently gained more and more popularity. All of these studies report on a variety of methodological approaches, but ignore a systematic selection of the variables to include.
Within the project SustainCity (www.SustainCity.org) an integrated land use transport simulation environment is being set up for the study areas of Paris, Brussels and Zurich. The implementation of location models into this simulation is limited through the data model of the simulation software. In order to understand these limitations we want to explore the objects and attributes that commonly have proved to be of relevance to residential location choice models.
In this paper we explore this topic and compare the variables that have been reported in recent literature of disaggregated residential location choice. The focus shall be an overview of the main findings, to understand common behaviour, and what therefore is necessary to represent in the data structure of urban simulation.

Titel: Modeling Hedonic Prices in Singapore
Kurzbeschreibung: This paper presents hedonic regressions for the Singaporean residential real-estate market. To these means, asking prices were collected from an online commercial property portal in February 2011. Transaction prices were collected from governmental data sets. These data sets are enhanced with locational data, such as vicinity to bus stops, MRT stations, supermarkets, (top) primary schools and other points of interests. Models were estimated with standard OLS, spatial auto regressive and geographically weighted regression methods for several sub-markets: private rental & buying and public (HDB) rental & buying. Floor area and distance to CBD are the most important drivers of house price. Dependent on the market, vicinity to public transport has a positive result. A higher floor level is considered positive as well. Furthermore, we find that spatial models function better than traditional OLS models and that using asking prices and transaction prices yields similar results despite the large difference between both types of prices.

Titel: Using discrete choice models to support strategic decision-making of air transportation service providers
Kurzbeschreibung: The focus of this paper is on understanding the relative valuation of non-monetary and monetary characteristics of an itinerary based on revealed preference data. A discrete choice modeling approach is followed. The research presented makes use of a number of datasets: a dataset that contains tickets bookings through computer reservation systems (CRS) for November 2006, a dataset with fares observed in the period September–November 2006 for flights departing in November 2006 on 70 origin-destination pairs and the Official Airline guide (OAG). They have been combined to form a comprehensive dataset for the analysis of itinerary choice. From this research it is concluded that the contribution to utility of fare is large: in a direct itinerary fare yields the largest contribution to utility, together with departure time. In an average non-chosen itinerary, the largest contribution to utility is given by a transfer. For airlines this implies that ticket prices and departure time are most important and that it is more important to influence network knowledge than brand knowledge. Dieser Beitrag beleuchtet das Verständnis der relativen Bewertung von nicht-monetären und monetären Charakteristiken eines Reiseplanes, resp eines Fluges basierend auf dem beobachteten Verhalten eines Reisenden (RP-Daten). Dafür werden Modelle der "random utility" angewendet. Für diese Studie wurden verschiedene Datensätze verwendet. Der erste Datensatz beinhaltet mittels Computer Reservation Systemen (CRS) gebuchte Flüge. Der Zweite enthält beobachtete Ticketpreise im Zeitraum von September–November 2006 für Abflüge im November 2006 auf 70 Quell-Ziel Beziehungen und der dritte Datensatz ist der Official Airline Guide (OAG). Die drei Datensätze wurden zu einem umfassenden Datensatz für die Routenwahl kombiniert. Das Fazit dieser Studie ist, dass der Ticketpreis vom Reisenden relativ stark bewertet wird. Bei einer Direktverbindung sind der Preis und die Abflugzeit am wichtigsten. Bei einer durchschnittlichen, nicht gewählten Flugverbindung ist das Umsteigen das wesentliche Entscheidungskriterium. Für Fluggesellschaften impliziert dies, dass Ticketpreise und Abflugzeiten entscheidend sind und es demnach wichtiger ist, die Streckenkenntnisse der Reisenden zu beeinflussen statt deren Markenbewusstsein.

Titel: Accounting for similarities in air transport route choice
Kurzbeschreibung: Overcoming the "independence of irrelevant alternatives" (IIA) property of the basic multinomial logit (MNL) model is a major research issue in the field of discrete choice modelling. In recent years, several approaches have been developed to achieve this goal. This paper focuses on similarities in the context of air connection choice. Due to the extensive choice sets in this study a similarity factor approach is applied, which does - even for this huge data set - not prolong estimation time. The scrutinized similarity factor has been specifically developed for public transport connections. It is capable to account for the complex and multi-dimensional nature of similarities of public transport alternatives. The optimal parameter setting for the similarity factor with respect to the dataset at hand is found. The estimation results emphasize that the similarity between alternatives exerts a significant influence on air connection choice. Similarity is perceived positive. It appears that decision-makers have a strong preference for certain attributes of the alternatives such as a specific departure time, travel time or fare. Thus, they prefer alternatives that are similar with respect to these attributes.

Titel: Consumer choice behaviour and strategies of air transportation service providers
Kurzbeschreibung: This paper presents an analysis of air traveller's itinerary choice in Europe. The analysis is based on three datasets, which cover altogether 70 origin-destination pairs in Europe. These OD-pairs differ in many aspects such as geographic coverage, number of available connections, number of transfers and travel time. The first dataset contains itinerary fares collected from the Web in the period September-November 2006 for flights departing in November 2006. The second dataset contains the booked travel itineraries in November 2006 through customer reservation systems. Finnaly, detailed itinerary information is obtained from the Official Airline Guide (OAG) By matching these three datasets, a data set has been derived that will allow to model the influence of several variables, e.g. departure time, travel time, code shares, number of transfers and fare, on the itinerary choice in air transport. With the derived data set, it is possible to construct a choice set with the alternatives an air traveller faced at the booking day. Estimated models include models with the sensitivity of air travellers for fare over time and per duration of stay. Also, a continuous departure time function is implemented in the choice model.2

Titel: Consumer choice behaviour and strategies of air transportation service providers
Kurzbeschreibung: The Institute for Transport Planning and Systems (IVT) is a research institute affiliated to the ETH Zurich and is specialized in, amongst others, transportation demand forecasting. The IVT expressed its interest to apply its knowledge in the field of aviation, following a general trend in the scientific community, thereby extending and expanding its knowledge of traveler choice behavior in general and air traveler behavior specifically. From an actor and network analysis, it is derived that numerous actors influence air traveler decision-making across a range of choice stages. It is chosen to highlight the itinerary choice stage in a case study, as only two actors are directly involved, namely airlines and travel portals. Furthermore, it is possible to address prevailing issues in the discrete choice community and the aviation industry. The focus of the case study is on understanding the relative valuation of non-monetary and monetary characteristics of an itinerary based on revealed preference data and investigating the role of different choice sets. A discrete choice modeling approach is followed. The research presented in the case study makes use of a number of datasets: a dataset that contains tickets bookings through computer reservation systems (CRS) for November 2006, a dataset with fares observed in the period September 2006 – November 2006 for flights departing in November 2006 on 70 origin-destination pairs and the Official Airline guide (OAG). They have been combined to form a comprehensive dataset for the analysis of itinerary choice. From the case study it is concluded that the contribution to utility of fare is large: in a direct itinerary fare yields the largest contribution to utility, together with departure time. In an average non-chosen itinerary, the largest contribution to utility is given by a transfer. In general it is concluded that the IVT can contribute significantly to current issues in the aviation industry. The fact that actual behavior in the case study is analyzed can prove both important for convincing both practitioners and researchers of the findings.2
