User acceptance of automobile subscriptions and flat rate models

Subscription or flat rate models are flexible alternatives which have been used for many years now, especially in relation to large data bases which are now available, for instance, to Netflix or Spotify customers. Hence, it is worth to explore more flexible usage models, not only in the media (e.g., streaming or music), but in the automotive industry as well. Indeed, especially young drivers or people living in the city, seem to prefer having a car ready to use for a specific time period when needed instead of owning the vehicle. Thus, compared to typical options drivers have, i.e. buying or leasing a vehicle, subscription or flat rate models offer drivers a way to book a vehicle in a flexible way which can be canceled at any point.

User acceptance of autonomous delivery robots in different application contexts

Recently, autonomous robots have been utilized increasingly for the delivery of food and packages. Even though these electrically powered vehicles have been used in the U.S. since 2018, pilot projects are just now becoming more popular in Germany. Due to their advantages for customers and society as a whole, delivery robots could become an important aspect of the scenery in future cities. More specifically, deliveries carried out by autonomous robots are environmentally friendlier and an efficient answer to the growing number of online deliveries. Furthermore, customers expect high flexibility as well as fast, but less-costly deliveries – demands which can be met by autonomous robots. However, user acceptance is essential for the successful implementation of this innovation. So far, user acceptance research surrounding autonomous delivery robots is limited and there is little empirical literature considering different application scenarios of the technology. Thus, two students of our business psychology program investigated factors influencing the customers’ acceptance of autonomous robots for last mile transportation of goods with a focus on current as well as potential future application scenarios.

First empirical insights into the user acceptance of hyperloop

Innovative mobility concepts have repeatedly been the subject of our research. This blog post summarizes the study results on the acceptance of hyperloop, a transportation method based on low pressure tubes and a magnetic levitation belt. Hyperloop promises a faster and more energy-efficient alternative, especially compared to airplanes. As with most innovations, one major challenge is gaining the acceptance of (potential) users. Due to the limited knowledge among the general public and little research around hyperloop, this study aimed at identifying the factors impacting user acceptance of hyperloop while focusing on different levels of the users’ knowledge about them.

How does the optimal mobility app look like? – An investigation of usage expectations, usage barriers and usability aspects

The Stuttgarter Straßenbahnen AG (SSB) has been providing mobility services in public transport in Stuttgart and the surrounding area for over 150 years. The goal of the SSB is to fulfill its tasks as customer-friendly as possible and thus to gain additional passengers – especially with a view to air pollution control. As an important step to increase the attractiveness of public transport in Stuttgart, the so-called polygo app is now to be developed. The polygo app is intended to become a user-friendly information and booking platform which offers access to multi-modal mobility offers in Stuttgart and the region. Mobility services offered by SSB FLEX, as well as bicycle rental, carsharing and e-scooter providers are to be integrated in the app.

What do people think about bike-sharing-systems? Examining the acceptance and usage

Riding a bicycle is environmentally friendly and good for your health – so it’s no wonder that 64% of Germans own a bicycle (Statista, 2021a). The number of bicycles in Germany last year was higher than ever before at around 79.1 million (Statista, 2021b). However, if you don’t own a bike, or don’t have it with you at the moment, many German cities offer the option of renting one. So-called bike-sharing systems have become increasingly popular in recent years. In the city of Berlin, for example, there are more than 15,000 rental bikes (Technologiestiftung Berlin, 2019).

Check-in/check-out in public transport: Understanding the users and the acceptance of CICO-BW app

I am sure many of you know this situation: Before using public transportation, you are wondering which ticket you need, how many zones your trip includes or which tariff you must pay (or which ticket is the cheapest alternative). These questions demonstrate that using public transportation in Baden-Württemberg is complicated, which diminishes the attractiveness and, thus, acceptance of public transportation. To support the transition to more sustainable mobility, a change in mobility behaviour is needed. Since facilitating the use of public transport is an important requirement of many people for using it (ADAC e. V., 2017), great attention should be paid to this aspect. Therefore, Baden-Württemberg started a project called CICO-BW. It involves the introduction of app-based e-ticketing with a check-in/check-out system and a daily best price guarantee.

How can we make cycling in big cities safer? Here’s the answer

Riding a bike can be an easy, fun, sustainable and healthy way of transportation. Considering these positive aspects of cycling, cities should focus on becoming more bicycle-friendly. While there are cycle enthusiasts that have used their bike for as long as they can remember and use it to go almost everywhere, 40% of cyclists in Germany do not feel safe when riding a bike (BMVBS & ADFC, 2019).

Looking at these suboptimal conditions for a sustainable future with increased bicycle usage, we decided that we wanted to change something. There must be a solution that makes riding a bike safer and is relatively easy and quick to implement. We wanted to make a sustainable impact on the bicycle infrastructure in cities. We found a way to do so.

How can (electric) Carsharing work in rural areas?

The concept of carsharing is pretty straightforward. Instead of owning a vehicle yourself and being attached to the acquisition costs, insurance, repairs and other running costs, you just pay for a vehicle whenever you need one (c.f. mobility on demand). Depending on the provider, costs are usually calculated as a mix between mileage and time. Carsharing offers you the benefits of using a car without the strings attached to owning a car. According to an analysis by Roland Berger (2014) private cars stay idle for 23 hours every day. Thus, carsharing is an environmentally friendly way to increase the efficiency of car usage.
