Titel: Online Grocery Shopping Survey
Kurzbeschreibung: The discrete choice modeling framework plays a dominant role in travel demand modeling. It is particularly suitable for choices with a compact choice set, such as mode choices. However, for spatial choices such as route or destination choices, which are in general characterized by a large number of alternatives, the choice set formation step poses crucial and to date unsolved methodological and empirical problems. This online survey provides data for stepping towards solving these important problems. The publicly available Web-based tool enabling an empirical approach to destination choice set formation is publicly available.2

Titel: Final Report: The Risk for a Gridlock and the Macroscopic Fundamental Diagram
Kurzbeschreibung: A solid base for modeling traffic gridlocks and their avoidance by control techniques exists for the strand of aggregate transport modeling. However, transport modeling continuously shifts from aggregate (macroscopic) to disaggregate (microscopic) models in recent years as with the movement from extending to managing the infrastructure, many important new questions came up, which can only be answered having the higher resolution of the disaggregate models (Kitamura (1996, Section 2) and Daly (2013)).2

Titel: Gridlock Modeling with MATSim
Kurzbeschreibung: Traffic gridlocks represent an extreme case of network impedance. In regions with increasing impedance due to higher loads, gridlocks are expected to become more frequent and thus more relevant; consequently, they cannot be neglected in transport models anymore. This paper starts the examination of MATSim's capability to model gridlock events. Closing Milchbuck and Schöneichtunnel being an eastbound arterial route is simulated. Furthermore, a side-glance is taken at single intersection modeling being highly relevant for gridlock simulation.2

Titel: Trip Purpose Identification from GPS Tracks
Kurzbeschreibung: Travel surveys are increasingly taking advantage of global positioning system (GPS) data offering precise route and time observations and potentially reduced response burden. In these surveys, travel diaries are usually constructed automatically, where research on the employed procedures has been focused on mode identification. This paper's goal is progress on trip purpose identification using random forests, a machine-learning approach which has been successfully applied to mode identification. Analysis is based on GPS and accelerometer data collected by 156 participants, taking part in a one-week travel survey in Switzerland completed in 2012. Results show that random forests provide robust trip purpose classification. For ensemble runs, a share of correct predictions between 80 and 85 % was achieved. Different setups of the classifier are possible, and sometimes required by the application context. The classifier's training set and its input variables (feature set) are defined in various ways. Four relevant setups are tested here.2

Titel: Distribution of Benefits and Losses From Roadpricing Illustrated in a Microsimulation Scenario
Kurzbeschreibung: This report describes the MATSim simulations performed to illustrate distribution of benefits in a road pricing context with trip-dependent varying preferences. The main hypothesis of the project Surprice is illustrated, that the inequality between income groups, induced by road pricing, in some cases might be smaller if intra-personal variation is also considered in the model rather than if only inter-personal variation is included in the calculation.

Titel: Integration of Activity-Based and Agent-Based Models
Untertitel: Recent developments for Tell Aviv, Israel
Kurzbeschreibung: This paper describes how the initial MATSim model of Tel Aviv has been updated and extended since its first version presented by Bekhor et al. (see 1). Main innovations are the inclusion of road pricing in the scenario and the incorporation of destination choice as an endogenous choice in the model. By conducting several experiments, it is shown that this implementation is able to fully replace the ad-hoc destination choice part of the first model. Furthermore, the model has been improved by several substantial updates in terms of data, such as population, network, zonal information, traffic counts, road pricing, trip length distribution. The outcomes of the calibrated model are compared to real world data as well as to the outcomes of the original model using EMME/2 for the traffic assignment. It is shown that the MATSim model reproduces the traffic flows very accurate and even better than EMME/2.2

Titel: An Agent-Based Cellular Automaton Cruising-For-Parking Simulation
Kurzbeschreibung: This paper reports on the development of an agent-based cruising-for-parking simulation using the cellular automaton (CA) approach. The software was tested on a small-scale scenario, and a first verification step was performed for a real-world scenario for the town center of Zürich. Approaches to integrating the simulation into MATSim, a multi-agent transport simulation program, are discussed. The software is open source and can be downloaded from a free software repository. Empirical data that may be valuable for future model calibration are currently being surveyed in a global positioning system (GPS) study at the authors' institute.

Untertitel: Rhythmischer Applaus als emergentes Phänomen?
Kurzbeschreibung: Wenn auch des Menschen Unheil darin begründet ist, dass er nicht ruhig auf seinem Baum sitzen konnte, so wurde immerhin mit dem Herabsteigen von den Bäumen seine Hände frei zur Benutzung als Werkzeug, nicht zuletzt als Ausdrucks- und somit Kommunikationswerkzeug. Eine Sprache dieses Werkzeugs ist das Klatschen, das sowohl individuelle Gefühle ausdrückt, als auch ein Gemeinschaftsgefühl stiften kann. Vermutlich am grössten ist das Kollektivempfinden beim rhythmischen Klatschen, oft beobachtet in Konzertsälen und teilweise in Sportstätten. In dieser Arbeit wird das Simulationsmodell ApplauSim für rhythmisches Klatschen (siehe z.B. Matthews (2000), Sumpter (2010)) entwickelt und sich der Frage angenähert inwieweit rhythmisches Klatschen als emergent betrachtet werden kann, d.h. als ein Phänomen, das mehr ist als die Summe der beteiligten Einzelteile.

Titel: A Glimpse at Emergence in Agent-Based Simulations
Kurzbeschreibung: Emergence, the formation of complex patterns generated by interaction of comparatively simple individual units, appears in many systems including transport system. Often, emergent effects are highly significant, consequently, the ability to reproduce them is crucial for modeling these systems. Multi-Agent-based simulations are due to their structural similarity to the modeled multi-part systems, expected to be particularly suitable for capturing these effects. The multi-agent transport simulation is focused here. The functional form of MATSim compo- nents, and, consequently, also its potential for emergence is not yet researched intensely. In this paper, the functional form of the network load simulation is studied with simulation experiments using a very simple scenario. To extend the discussion, additionally ApplauSim, a simulation of synchronized applause developed by the authors, is presented.

Titel: Searching for Parking in GPS Data
Kurzbeschreibung: Parking search is widely accepted to be a significant contributor to congestion in city centers. The high parking occupation on Saturdays in Zurich suggest this also an issue there. Raw person-based GPS data from Switzerland and especially Zurich is analysed regarding parking search characteristics. For processing the POSDAP routines developed at the institute are extended. The descriptive analysis considers driving times and distances but also subsequent walk stages. Results suggest that search traffic is a local phenomenon and not as dramatic for the overall city as expected.

Titel: High-Resolution Destination Choice in Agent-Based Demand Models
Kurzbeschreibung: This paper describes the modeling of destination choice for discretionary activities in a multi-agent transport simulation, using MATSim as an example. MATSim is based on utility maximization. Randomness was included implicitly and in an uncontrolled way through the stochasticity of the simulation process, and sometimes through a logit choice model. Unobserved heterogeneity is now added directly to the utility function through a random error term. Importantly, those random error terms are quenched, i.e., they will be the same for repeated executions of the choice model. Real-world simulation experiments for Zurich show that this substantially improves results. High-resolution destination choice for large-scale microsimulations raises several technical issues; pragmatic engineering solutions have been developed or applied to cope with them. These solutions are described in technical detail to assist in the further development of similar microsimulations.

Titel: Coupling Customers' Destination Choice and Retailers' Location Choice in MATSim
Kurzbeschreibung: The multi-agent transport simulation MATSim (MATSim, 2012) contains modules for cus- tomers' destination choice (Horni et al., 2012) and retailers' location choice (Ciari and Axhausen, 2011; Horni and Ciari, 2009, 2011). This paper's goal is combining these two models into a dynamic and micro-simulated demand-supply model for shopping activities. Both models are methodologically improved by analyzing retailer clustering and its effects on customer destination choices and by discussing extension of the normative retailer location choice model toward a behavioral model.

Titel: How to Improve MATSim Destination Choice For Discretionary Activities?
Kurzbeschreibung: This paper proposes ways to improve MATSim destination choice for discretionary activities. Naturally, small-scale destination choice models can feature a much higher level of detail than large-scale microsimulation scenarios. This upscaling problem mainly concerns data availability and computational limitations, but, due to the relative novelty of microsimulation destination choice models, also a certain implementation lag exists. This paper discusses on the example of MATSim and in a preliminary sense, where upscaling of small-scale findings for application in large-scale microsimulation scenarios is possible and potentially beneficial.2

Titel: Variability in Transport Microsimulations Investigated With the Multi-Agent Transport Simulation MATSim
Kurzbeschreibung: Transport microsimulations are stochastic. Randomness is, for example, introduced by the error terms of discrete choice models, a common component in utility-based microsimulations. This leads to random variability in results at all resolution levels. This paper's objectives is an analysis of this variability. As a very common and important aggregate measure in transport planning network link volumes are analyzed, based on MATSim simulation experiments. Constrained by modeling and simulation costs, recent large-scale, high-resolution microsimulations are cross-sectional models. When looking at aggregate levels relevant to planning, for common statistics there is relatively little variability over multiple simulation runs. However, these models do not properly account for temporal variability. This is problematic because temporal variability measured in reality is substantial. Thus, considering extension of these cross-sectional microsimulation models to longitudinal models will be necessary in the near future. To support this, the paper also documents first insights about temporal variability and temporal correlations in microsimulations.2

Titel: Variability in transport microsimulations investigated for MATSim
Untertitel: Preliminary results
Kurzbeschreibung: As part of the recent integration of destination choices for discretionary activities, mechanisms to explicitly treat unobserved heterogeneity in MATSim were developed. This potentially introduced a large amount of randomness to the model as so far the MATSim utility function was deterministic. Adding randomness to a model clearly makes necessary variability analysis. In this paper first steps in assessing the variability of MATSim results are undertaken. The results are preliminary and need comprehensive verification and elaboration.2

Titel: Empirically approaching destination choice set formation
Kurzbeschreibung: The discrete choice modeling framework plays a dominant role in travel demand modeling. It is particularly suitable for choices with a compact choice set, such as mode choices. However, for spatial choices such as route or destination choices, which are in general characterized by a large number of alternatives, the choice set formation step poses crucial and to date unsolved methodological and empirical problems. In this paper, steps towards solving these important problems are introduced. The core of this paper is a publicly available Web-based survey tool that enables an empirical approach to destination choice set formation and that also has potential use in collaborative efforts. A detailed analysis of the problems associated with destination choice set formation and first approaches for model estimation are included.

Titel: Pushing the limits
Untertitel: A concept of a parallel microsimulation framework
Kurzbeschreibung: This paper describes the concept of a versatile transport simulation framework to be used for the development of integrated transport simulation models. It is designed to improve modularization and thereby simplify the collaboration between scientists and engineers from different fields. Modularization is believed to be important due to the increasing complexity of the implementation task if models from different areas are to be integrated. In performance critical software projects this complexity is often further increased by the desire or the need for an implementation that can be run in parallel on multiple processors. Furthermore, developing an efficient parallel simulation is not trivial. In addition to the complexity of the modeling task as such one has to deal with communication delays and data availability issues. The idea of the presented framework is to handle this complexity by defining simple rules according to which user developed modules must act. These rules include certain minimum delays between the observation of a change in the system and the triggered reactions, limited vision, and limited traveling speed. To illustrate how the framework is to be used a simples modeling scenario is created and a possible implementation employing the framework is sketched. The example scenario consists of the integration of a pedestrian simulation with a load estimation module and a travel time estimator. Finally, an outlook on the next steps in the development of the framework is given.

Titel: Agentenbasierte Simulation für location based services
Kurzbeschreibung: Mobilität bildet den Grundpfeiler auf dem ortsbasierte Dienstleistungen (Location Based Services) ruhen. Darum ist ein präzises Abbild der Mobilität der zu erreichenden Zielgruppen für diese Art von Diensten unerlässlich. Mikrosimulationsmodelle zur Generierung von Mobilität liefern hierzu eine vollständige Mobilitätsanalyse, inklusive der Entscheidungsfindungsprozesse mobiler Individuen und somit die Verknüpfung statistisch relevanter Kenngrössen für unterschiedliche demographische und sozio-demographische Gruppierungen mit detaillierter, dynamischer Mobilität. Diese Eigenschaften bilden den Kernaspekt zur Dimensionierung von ortsbasierte Dienstleistungen. Basierend auf dem Open-Source Forschungsprojekt MATSim ist das erste, vollständig integrierte Umlegungs- und Verhaltensmodell für Zeit-, Routen-, Verkehrsmittel- und Ortswahl für die gesamte Schweiz entstanden.

Titel: Location choice modeling for shopping and leisure activities with MATSim
Untertitel: Combining micro-simulation and time geography
Kurzbeschreibung: The activity-based multiagent simulation toolkit MATSim adopts a coevolutionary approach to capturing the patterns of people's activity scheduling and participation behavior at a high level of detail. Until now, the search space of the MATSim system was formed by every agent's route and time choice. This paper focuses on the crucial computational issues that have to be addressed when the system is being extended to include location choice. This results in an enormous search space that would be impossible to explore exhaustively within a reasonable time. With the use of a large-scale scenario, it is shown that the system rapidly converges toward a system's fixed point if the agents' choices are per iteration confined to local steps. This approach was inspired by local search methods in numerical optimization. The study shows that the approach can be incorporated easily and consistently into MATSim by using Hägerstrand's time-geographic approach. This paper additionally presents a first approach to improving the behavioral realism of the MATSim location choice module. A singly constrained model is created; it introduces competition for slots on the activity infrastructure, where the actual load is coupled with time-dependent capacity restraints for every activity location and is incorporated explicitly into the agent's location choice process. As expected, this constrained model reduces the number of implausibly overcrowded activity locations. To the authors' knowledge, incorporating competition in the activity infrastructure has received only marginal attention in multiagent simulations to date, and thus, this contribution is also meant to raise the issue by presenting this new model.

Titel: Location choice modeling for shopping and leisure activities with MATSim
Untertitel: Combining micro-simulation and time geography
Kurzbeschreibung: This paper presents validation results for the activity-based multi-agent transport simulation MATSim (http://www.matsim.org), where the main focus lies on the location choice module for shopping and leisure activities. Validation results are produced by simulating a 10% sample of the Swiss motorized individual traffic. For Switzerland detailed information about home, working and education locations together with the associated trip matrices are provided by the census. Naturally this level of detail is not available for shopping and leisure trips. In MATSim so far—to create feasible activity chains—location choice for these activities was done in a preprocessing step based on a simple nearest neighbor search, which clearly leads to a systematic underestimation of the traffic volume. In this paper a two-fold shopping and leisure location choice model is presented that produces substantially better results. First and foremost, the to-date exclusively time-based utility function for shopping activities is extended to take into account further determinants of shopping location choice, such as the store size and the stores density in a given neighborhood. In activity-based models, shopping location choice is influenced by leisure location choice, which means that a meaningful shopping location choice model requires a sound leisure location choice model. The long-term goal of MATSim is to model leisure location choice by utility maximization and by including models of social interaction. But these models are far from being productive in agent-based transportation models in general. Hence, we introduce hollow space-time prisms that are derived from empirical data. This approach is—to our knowledge—a novel extension of Hägerstrand's time geography that by construction produces statistically correct leisure location choice and improves the simulation results in general. Furthermore, the potential of MATSim to also serve as a hypothesis testing tool—besides being a planning tool—is highlighted in this paper. It is shown that MATSim provides the possibility to test models, generated by utility maximizing approaches such as e. g., discrete choice models, in large scenarios, whereby use can be made of data (e. g., count data) that is potentially qualitatively distinct from the data that were used for estimating and validating the models in question in earlier stages.2

Titel: Location choice for leisure and shopping activities implemented in the activity-based multi-agent transport simulation MATSim
Kurzbeschreibung: This paper presents the concept and implementation of the MATSim (Multi-Agent Transport Simulation Toolkit) location choice module for shopping and leisure activities and shows first simulation results for the Zürich region of Switzerland using more than 60,000 people and 7,800 shop or leisure activity locations. MATSim is designed to handle large-scale scenarios. Thus, computational efficiency, that is fast convergence to a Nash Equilibrium, while maintaining behavioral precision is a fundamental objective. We show that to achieve this goal Hägerstrand's time-geographic approach can be incorporated easily and consistently into MATSim and into disaggregated location choice simulations in general. Our novel time-geographic algorithm, tailored for the use in MATSim, is derived from a potential path area algorithm. It is extended to handle chains of multiple shop or leisure activities between two anchored activities (i.e., those with fixed start times, durations and locations) by using recursion. To improve both the behavioral precision and the stability of our model, we show how timedependent capacity restraints can be incorporated explicitly into iterative disaggregated location choice simulations, as capacity restraints for activity locations have an effect on people's location choices, similar to the effect of road capacity restraints on people's route choices. To our knowledge, to date, only static activity location attributes, such as opening hours and location size, are incorporated explicitly in disaggregated location choice simulations and thus our contribution is also meant to open up a discussion.
