EcoSensorBike – measuring bicycle for student research in the field of traffic ecology

Supported by the Dr. Joachim und Hanna Schmidt Foundation for Transport and Environment, the Institute for Transport Systems and Infrastructure of the Karlsruhe University of Applied Sciences is developing a measuring bicycle that can measure a wide variety of bicycle traffic parameters using sensors. The following parameters are regarded:

  • the energy demand when cycling (longitudinal inclination, wind speed, road surface, etc.)
  • the influencing variables that determine the ride comfort of cyclists (weather, climate, etc.)
  • the influencing variables of traffic safety (side distances, braking acceleration, etc.)
  • the interactions between different cyclists (slipstreaming, traffic conflicts, etc.).

The measuring bicycle also enables the linear measurement of traffic related environmental impacts.

GEFONAS - Joint Research for Sustainable Urban Development and Mobility

Karlsruhe University of Applied Sciences and Technology is operating a joint research project with Sungkyunkwan University (SKKU) in Suwon, South Korea. The German Federal Ministry of Education and Research (BMBF) is funding this project. Also Karlsruhe Institute of Technology (KIT) and Seoul National University (SNU) in Seoul, South Korea take part in this project.


The research has four main topics:

  • Urban and district development:
    The comprehensive main topic is urban planning that deals with careful development of neighborhoods. Previous cooperation were conducted with "Urban Voids" project between German and Korean universities. In last project urban and district development was a main topic, however in the framework of cooperation other 3 research themes below were also emphasized.
  • Urban compatible mobility:           
    Urban compatible mobility is a connecting point to other topics. In this project, collaboration with South Korea, where their technology is advanced has special potentials for development of systems for the organization and optimization of multimodal and intermodal mobility. In the Urban Voids project, common interests were remarkable in the field of local supply, local mobility, promotion of cycling & pedestrian traffic and the coordinated design of urban street spaces.
    Additionally autonomous driving plays a special role in this project: both the Korean and German cooperation partners are involved in research projects on this theme. In addition to the technical issues, however, joint research and development activities should consider also the effects of autonomous driving in terms of urban and transport planning goals.

  • Handling of heavy rain:        
    Heavy rain are occurring worldwide. With this situation, the question is raising how to deal with the undrained runoff through existing sewage system. As a part of the Urban Voids project, this issue has already engaged in the workshop that professionals planned for the regeneration of the Sangdo4-dong. Workshop participants led to various design approaches for the streets. Now we are trying to different approaches to realize it in R&D projects of both countries.

  • Sustainable energy supply, potential of hydrogen energy:
    Energy supply and its sustainable design are placing on a high priority in both countries. In addition to the supply of buildings with heating and electrical, there is also an increasing focus on energy for the mobility sector as well as the decentralized generation and use of renewable energy.
    In the field of mobility, much of countries are strongly prompting electric vehicles, but due to the still limited ranges, the charging time and supplying charging infrastructures are still controversial. There is also great potential in hydrogen- and fuel-cell-based drives, but here, too, acceptance among customers is still manageable.
    A comprehensive consideration of regenerative, decentralized energy generation in the context of urban planning and mobility is therefore, another focus of GEFONAS.
Goal

The goal of GEFONAS in the coming years is to network project partners in Germany and South Korea, to develop, product research ideas. In addition, we aim to collaborate on research and development work in the context of funded projects.

GO Karlsruhe: A Real World Laboratory researching the Behavior of Pedestrians and developing New Approaches for Citizen Participation

The real-world laboratory aims to promote walking and to get residents involved. Together with the research team pedestrians in Karlsruhe identify measures to improve walkability and develop solutions for existing problems. This is done with new digital participation instruments as well as in conventional participatory processes, where events are taking place in the districts. In real-world experiments these ideas are implemented and subsequently analyzed to determine whether the desired improvement has been achieved and which aspects (still) have to be considered.

You will find details on the German-language project website.

The city of Karlsruhe
The radio station die neue welle
SRL - Vereinigung für Stadt-, Regional- und Landesplanung (Society for Town Planning, Regional Planning, and Federal State Planning)

KATZE: Karlsruhe University of Applied Sciences Zero Emission!

A team from Karlsruhe University of Applied Sciences started working for the research project KATZE in November 2018 as part of the ideas competition “Mobility concepts for an emission-free campus”. CO2-emissions caused by university operations are analysed. Based on this, measures are examined which have the potential to influence mobility behaviour and building emissions sustainably.

The work is characterised by being:

  • Integrative: Research is part of campus development.
  • Interdisciplinary: The knowledge of different specialist areas is bundled.
  • Evidence-based: The research results should be transferable to other, comparable campuses.
  • Adaptive: Promising concepts should be continually adjusted in the ongoing process to ensure emission-free mobility in future.
  • Participatory: All users of the campus will be involved.

The project is divided into several steps:

Step 1 - Analysis of framework conditions:

In order to be able to calculate the emissions of the Karlsruhe University of Applied Sciences, many different framework conditions are analysed. This includes, for example, the determination of the traffic performance of the vehicle fleet or the existing infrastructure. The data on CO2-emissions are summarised in an environmental model.

Step 2 - Development of a transport mode choice and impact-model:

By using a representative mobility survey, the availability of means of transport and the traffic behaviour of students and employees are determined. Based on the results, a transport mode selection will be developed. Changes in mobility behaviour can be represented with this model and emissions from different scenarios can be calculated.

Step 3 - Campus model development:

All departments together develop a campus model which represents the overall development of the campus. This includes the further development of the buildings as well as measures for modal shift and traffic reduction.

Step 4 - Participatory and adaptive planning process for mobility concepts:

In a real world laboratory all members and visitors of the Karlsruhe University of Applied Sciences can take part in the process. Exhibition boards inform about current developments and encourage visitors to actively participate in the planning process. In a playful way, solutions are sought. Specific knowledge of different groups can thereby be recorded.

Step 5 - Implementation of first measures:

Measures that are expected to have a high impact and which can be implemented quickly are already implemented in the concept phase. In this way, an early visible implementation of the mobility concept can be reached.

Step 6 - Model mobility concept presentation:

The mobility concept and its effects are presented using an interactive campus model. The model will be presented to the university public after one year as part of the participation process. All stakeholders can make use of it and add new findings.

Development of methodological approaches and modelling tools for low-energy neighbourhoods (NEQModPlus)

In this research project, methods and instruments for the support of decision-making and implementation of low-energy quarters will be developed. This applies both to the redevelopment of existing buildings as well as the construction of new ones. The primary energy balance should thereby be reduced by at least 70 %.

The target group of the project are quarters with residential and administrative buildings as well as university campuses. The results enable decision-makers as well as other actors to promote the development of sustainable NEQs in a structured way.

The object of the project is the development of a methodology for the step-by-step development as well as the implementation and management of NEQs in line with the objectives. In contrast to existing approaches, mobility is also included in the energy concept.

Subproject Mobility of the Karlsruhe University of Applied Sciences

The topics of mobility, settlement structure and energy supply are currently still regarded in a very isolated way. Little is known about the interactions between energy-optimised quarter planning and sustainable mobility behaviour. Through sector coupling, regenerative or locally generated energy could be used for mobility.

The aim of the Mobility sub-project is to combine the contemplation of energy supply and mobility compatible with urban areas. Among other things, possible mobility management measures and innovative drive technologies will be examined.

On the basis of the evaluation of ten quarters, tried and tested solutions from energy efficiency and supply measures are determined. The traffic-generating effect of the quarters is estimated and the expected energy consumption calculated from this. Subsequently, it is examined how this can be covered within the framework of a low-energy concept. In three pilot quarters, modelling processes and implementation instruments will be used and tested.

Optimal recycling of construction asphalt on low-traffic roads (ORRAP)

Problem statement

Large quantities of high-quality aggregates and bitumen are required for the maintenance and expansion of roads, which are mixed and paved into various asphalts. At the same time, large quantities of asphalt are generated during rehabilitation measures. The high-quality recycling of old asphalt resulting from remediation measures protects the non-renewable resources aggregates and bitumen as well as the environment. If old asphalt is recycled without the addition of bituminous binders, the trade and recycling of old asphalt can be increased and the impact on the environment and the costs for road maintenance can be reduced.

Projects aims

The aim is to develop a strategy that ensures a high recycling rate of old asphalt and reduces negative environmental impacts and road maintenance costs. Old asphalts with an inhomogeneous composition are currently used in too small quantities in layers without binding agents. This is expected to change.

Fundamental project objectives are:

  • Analysis and exchange of experiences on asphalt recycling in the Upper Rhine region.
  • Development of a new recycling strategy for old asphalt in the Upper Rhine region.
  • Evaluation of the economic and environmental impacts in the Upper Rhine region.
  • Development and provision of recommendations for the optimal performance.
