Within-day replanning of exceptional events
(2011)Arbeitsberichte Verkehrs- und RaumplanungTypical software that is used for the simulation of traffic behavior focuses on scenarios that describe common situations like an ordinary working day without remarkable incidents. To simulate such scenarios, iterative approaches are used. They assume that the simulated people adapt to the results of the previous iterations. Such iterative approaches produce meaningful results for various scenarios as long as only typical, repetitive ...Working Paper -
Modeling household fleet choice as a function of fuel price using a multiple discrete-continuous choice model
(2011)Arbeitsberichte Verkehrs- und RaumplanungIn this Paper, a new model of fleet choice for households is presented that uses the multiple discrete-continuous extreme value (MDCEV) model as a framework. The aim of the model is to establish a model to allocate car types to activity based microscopic agent based transport simulations. What is new in the presented model, is that in addition to socioeconomic attributes of households, the choice is also influenced by fuel price. To model ...Working Paper -

High-resolution destination choice in agent-based demand models
(2011)Arbeitsberichte Verkehrs- und RaumplanungThis paper describes the modeling of destination choices for discretionary activities in a multiagent transport simulation, using MATSim as an example. MATSim is based on utility maximization and its utility function has always been deterministic. Unobserved heterogeneity is now added to the utility function through a random error term, meaning that MATSim is now fully compatible with discrete choice theory. Real-world simulation results ...Working Paper -
How to model the gains from infrastructure investment?
(2011)Arbeitsberichte Verkehrs- und RaumplanungThis paper is a reply to Metz recent book (2008), in which he pointed out, that current costbenefit practise assumes that short-term gains provide a full picture of the gains from investment. It is also an attempt to sketch the model, which is needed to give the decision makers an idea of the long term impacts of the their short term choices. This would help to avoid overly myopic decisions.<br/>The paper sketches a thought model of how ...Working Paper -
Surveying data on connected personal networks
(2011)Arbeitsberichte Verkehrs- und RaumplanungThis survey study combined name generators with snowball sampling to collect information on personal leisure networks and underlying “global” network structure. Although such an ar- rangement is not unusual, this large-scale study - with around 700 respondents - reported nearly 15’500 social contacts. Furthermore, snowball chains were limited to leisure contacts with no further limitation on collecting data or continuing recruitment. While ...Report -
Potenzial von Fahrgemeinschaften
(2011)Eidgenössisches Departement für Umwelt, Verkehr, Energie und Kommunikation UVEK, Bundesamt für StrassenWenn eine Person für eine Fahrt, welche sie ohnehin durchführt, in ihrem Auto andere Personen mitnimmt, dann spricht man von einer Fahrgemeinschaft oder im englischen Sprachgebrauch von Car Pooling. Die Idee, diese Mobilitätsform durch Vermittlung ge- zielt zu fördern, stammt aus der Zeit des „Ölschocks“ in den Siebzigerjahren des letzten Jahrhunderts und wurde seither in vielen Ländern auf unterschiedliche Art verfolgt. Trotz einigen ...Report -

Influence of parking on location and mode choice
(2011)Arbeitsberichte Verkehrs- und RaumplanungThis paper assesses the effects of parking availability on behavioral responses by travelers, and which approaches are appropriate for modeling those responses. In addition to the well-known trade-offs between travel times and fuel or transit ticket costs, parking search times and costs have a significant impact on travelers’ decisions. A stated choice study of parking, location, and mode choice was conducted to assess those choices. The ...Working Paper -
Interdependencies between turning points in life and long-term mobility decisions
(2011)Arbeitsberichte Verkehrs- und RaumplanungTurning points in life include important personal and familial events as well as changes in the places of residence, education and employment. The latter usually involve alterations in the spatial distribution of activities and, hence, in the activity space, thereby also influencing the daily travel behavior. In this context, the ownership of mobility tools, such as cars and different public transport season tickets, also plays an important ...Working Paper
