Automobility in flux: More women and older drivers at the wheel

Having barely registered an increase at the beginning of the new millennium, during the economic upturn after 2009, there was significant growth in the mileage by registered motor vehicles in Germany, both in the case of utility vehicles and automobiles. Overall, in 2011, automobiles covered a higher mileage than ever before. Despite more efficient engines, this resulted in fuel consumption stagnating in recent years, although the long-term trend is one of decline. With an 85-percent share of total mileage, automobiles dominate our roads. This transport demand pattern is predominantly created by the needs of private households and it is currently in a state of flux when it comes to gender and age balance. Women's growing presence in education and on the labor market has, in turn, resulted in an increase in their car ownership and mileage. At the same time, men and women are maintaining a more mobile lifestyle by retaining their cars into older age. However, more limited car use has been observed, particularly among young people who, more frequently than previously, seem to be opting for the most suitable form of transport rather than traveling exclusively in their own vehicles

Does Supervision in Multiday Travel Surveys Lead to Higher Quality? A Comparison of Two Independent Surveys

The aim of this paper is to analyze whether the level of supervision influences quality of response and results of multi-day surveys. For that reason, we compare a multi-day survey (seven consecutive days) with children and high level of supervision in Austria (UTS) with data of the same age group out of the Mobility Survey in the Greater Stuttgart Region (MOSt). The results show that supervision during the survey process has nearly no influence on fatigue effects. Nevertheless, the quality of answers in supervised surveys is be better in terms of reporting intermodality or trip stages

Workshop synthesis: Measuring attitudes and perceptions in large scale (quantitative) surveys

This paper presents the main outcomes of the workshop A5 Measuring attitudes and perceptions in large scale (quantitative) surveys. There is a big need in the community to include more questions about psychological factors in surveys, because the travel behavior is getting more divers. The workshop discussion revealed that while there are different survey methods to capture information about the participants’ psychology, Likert scales are mainly used because they are easy to implement and to fill in. However, the reliability of the results must be assessed in light of the survey method and type of analysis. Further research is needed to combine quantitative surveys with methods to collect psychological information

Integration von neuen Mobilitätsformen in Verkehrserhebungen und Verkehrsmodellierung

New technologies and forms of mobility are gradually becoming part of today’s transportation supply. These new forms of mobility include, for example, car- or bikesharing and ridepooling, as well as new technologies such as electric mobility or automation. To take these new forms of mobility into account in transport planning tools, it is advisable to adapt both surveys and models

Elektromobilität: Integration von Elektromobilität in die Verkehrsplanung – Welche Anpassungen unserer Werkzeuge brauchen wir?

Die Integration von Elektromobilität in die Verkehrsplanung und im Speziellen in Verkehrserhebungen und Verkehrsnachfragemodellierung, kann mit einigen Anpassungen und der Verwendung von agen-tenbasierten Modellen gut durchgeführt werden. Dabei sind die Charakteristika der Nutzenden/Besit-zenden von elektrisch betriebenen Fahrzeugen, die Eigenschaften der Elektrofahrzeuge v.a. hinsicht-lich Reichweite und die zusätzliche Berücksichtigung der Ladevorgänge bzw. Ladeinfrastruktur zu be-rücksichtigen. Zur Abbildung der Ladevorgänge sind Erhebungs- und Modellierungszeiträume notwen-dig, die einen so langen Zeitraum umfassen, so dass hinreichend viele Ladevorgänge und somit eine Fahrleistung jenseits der Reichweiten vorhanden sind. Nur so können Variationen im Verkehrsverhal-ten und bei Ladestrategien berücksichtigt werden

Mikroskopische Modellierung des Außenverkehrs eines Planungsraums

Im Rahmen der mikroskopischen Verkehrsnachfragemodellierung wird ein Modell vorgestellt, das den für den Planungsraum relevanten Verkehr der in den Außenzellen wohnenden Personen abbildet. Voraussetzung dafür ist die Übertragbarkeit von individuellen Mobilitätsdaten, die auf Basis der Daten des Deutschen Mobilitätspanels (MOP) analysiert wird. Darüber hinaus wird eine Methode zur Abgrenzung von Untersuchungsgebieten für beliebige Planungsräume in Deutschland dargelegt

Usage and User Characteristics - Insights from MOIA, Europe’s Largest Ridepooling Service

New, i.e., shared and digitized, mobility services have been entering urban mobility markets around the globe. Among these new offerings is ridepooling, a mobility solution that bundles requests from passengers with similar routes in real-time and matches them with a vehicle. Ridepooling is quite novel in Germany and knowledge about users, changes in travel behavior, and impacts on the urban traffic system is scarce. To address this gap, we conducted an online survey among users and non-users of MOIA, a German ridepooling provider. Over 12,000 respondents completed the survey. The article presents results on ridepooling users’ characteristics and usage patterns. We found that MOIA users cover all age groups and are multimodal travelers—which leads us to assume that ridepooling enriches mobility portfolios and also serves as an alternative to the private car. MOIA is mostly used occasionally and, in particular, during the evening or the night. A specific focus of the article lies on users with mobility impairments as well as how and by whom ridepooling is used on work-related trips. Both topics are particularly relevant in light of changing travel patterns and transforming urban transport systems towards more sustainability

Accompanying Research on Automated Minibusses in Monheim am Rhein : Report on Results

The shift towards sustainable transportation has led to the expansion of public transit as a central objective. An innovative step in this direction is the introduction of automated minibusses, which have been deployed in Monheim am Rhein since February 2020 as Germany\u27s first automated minibus fleet in regular service. The aim of the city and Bahnen Monheim as the operator of the small bus fleet is to make public transit more attractive through the automated minibus service, increase traffic safety, and familiarize the population with automated driving and, thus, digitization. The Institute for Transport Studies at the Karlsruhe Institute of Technology (KIT) accompanied the introduction and operation of the automated minibus fleet in Monheim am Rhein over a period of two years with empirical studies to explore the acceptance and impacts on the mobility behavior of the Monheim population. By conducting repeated passenger interviews, usage patterns and behavioral changes over time since the introduction of the service are identified. Interviews with the accompanying personnel of the automated minibusses provide additional insights into the acceptance of the novel service. Based on a household survey among all residents of Monheim am Rhein, representative insights into the attitudes of users, especially non-users, are obtained. The results show that primarily women, older people, and individuals with mobility impairment use the existing service. For the latter two groups, in particular, the automated minibus serves as a facilitator of mobility. The integration of automated minibusses into the existing bus network has increased the accessibility of public transit and further promoted its use. Overall, high satisfaction levels among users of the automated minibusses and a clear willingness to use them among non-users are observed. Safety concerns regarding the automation technology of the automated minibusses cannot be identified among the residents, partly due to the presence of accompanying personnel. Of greater importance is the service function perceived by the accompanying personnel themselves, as well as by the passengers, such as assistance with boarding and exiting. Despite the generally positive perception, the accompanying research identifies expansion potential of the automated minibus service to reach a larger user group. This includes measures, such as increasing travel speeds and improving driving behavior, as well as expanding the service area, such as intermodal use as a feeder to the nearest train station. The study suggests considering further information campaigns to promote a unified understanding of automated driving and the automated minibus service. This can create additional acceptance for the current weaknesses of the service
