Results of our surveys in Marburg (MoVe 35): Final presentation

As part of a joint digital exchange with the city administration of the city of Marburg (including citizen participation and transport planning) on September 25, 2024, the research group presented the results of the surveys in connection with the participation process for the MoVe 35 mobility and transport concept. The MoVe 35 project was one of a total of five planning projects that were intensively investigated by the CIMT research group over several years in order to examine the effects of consultative citizen participation on political attitudes, among other things.

Various participation formats were carried out as part of the planning process, e.g. an online survey, workshops, a project advisory board and an online dialog on public transport. A (council) referendum was also held in connection with the mobility concept. Further information on the MoVe 35 project and the participation formats used can be found on the city of Marburg’s website.

This planning and participation process was examined by the CIMT research group at Heinrich Heine University Düsseldorf independently (i.e. without being commissioned or influenced by the city of Marburg), primarily with the help of surveys of Marburg residents. For this purpose, a randomly selected part of the population in Marburg was surveyed in 2021 and 2024. Further information on the research group’s surveys can be found here.

Selected results

As in all of our project areas, transport policy and the transport transition are conflicting issues. In Marburg, however, there is a particularly clear contrast between the educational groups. For example, the majority of people without a high school diploma reject the idea of reducing space for car traffic in the future, while almost half of those with a high school diploma can imagine doing so.
Supporters and opponents of the mobility transition were similarly represented in the participation process. It was noticeable that an above-average number of car drivers took part in Marburg.
The measures envisaged as part of Move 35 are viewed positively by the majority of people with high education in order to achieve the goals of sustainable mobility – in contrast to people without high education.
The very different assessments of the two educational groups are also evident in the (planned) voting behavior for the referendum on halving car traffic: the majority of people with high education are in favor, the majority of people with low education are against, and participants in the consultation process are divided.
Although satisfaction with the local institutions (mayor, city administration, council) was slightly better overall than in other project areas, it deteriorated significantly between 2021 and 2024 among people with low education.
The information on the participation process reached a large part of the population. Nevertheless, it was mainly highly educated middle-aged men who took part – typical of consultative participation. It had a relatively large impact on citizens’ satisfaction with the mayor, administration and council. As expected, people who welcome the measures of MoVe 35 tend to be more satisfied, while those who reject the measures express greater dissatisfaction.

Results of our surveys in Offenburg (OG 2035): Final presentation

In a joint meeting with representatives from the city of Offenburg’s urban development and transport planning departments on October 11, 2024, the research group presented the results of the surveys conducted in connection with the participation process for the OG 2035 Transport Master Plan. The Transport Master Plan OG 20235 was one of a total of five planning projects that the CIMT research group studied intensively over several years in order to investigate the effects of consultative citizen participation on political attitudes, among other things.

Various formats were carried out as part of the planning process, e.g. online dialogs, workshops, local forums, youth participation and the establishment of pop-up measures. Further information on the OG 2035 project and the participation formats carried out can be found on the City of Offenburg website.

This planning and participation process was examined by the CIMT research group at Heinrich Heine University Düsseldorf independently (i.e. without being commissioned or influenced by the city of Offenburg), primarily with the help of surveys of Offenburg residents. For this purpose, a randomly selected part of the population in Offenburg was surveyed in 2021 and 2023. Further information on the research group’s surveys can be found here.

Selected results

Transport policy and the transport transition are conflicting issues in Offenburg – just like in all other project areas examined. All opinions were represented in the participation process, although those in favor of the mobility transition were somewhat stronger and car users were also less common.
Satisfaction with the local institutions (mayor, city administration, council) is rather average overall (and slightly worse than in other project areas) and deteriorated significantly from 2021 to 2023 in particular.
The transport measures adopted as part of the OG 2035 master plan do not satisfy all interests, but overall only a minority (20-25%) are really against them. People who took part in the participation process rate the results more positively overall.
As with most open participation formats, the participants are not representative of the population. They are mainly people with a high school diploma, middle-aged people and men.
The participation process had a (comparatively low) and overall negative influence on satisfaction with local politics and administration, whereby the city administration was rated more positively than the mayor and council, especially by the consultation participants. As expected, people who welcome the measures of OG 2035 tend to be more satisfied, while those who reject the measures express greater dissatisfaction.

Acceptance for transformation projects through public participation? A plea for more realism

In this article in the eNewsletter Netzwerk Bürgerbeteiligung, Tobias Escher, Katharina Holec and Laura Mark make the argument for a more realistic view of the role of citizen participation in the sustainability transformation. Based on four theses, they explain that conflict resolution – even though this is often associated with participation – does not do justice to the role of public consultations, but that consultations are nevertheless indispensable in the political shaping of transformation.

Summary

The article puts forward a total of four theses, each of which is supported by findings from the research of the CIMT project. These are as follows:

Thesis 1: Citizen participation can lead to mutual understanding, but generally not to a consensus on fundamental conflicts of interest.
Thesis 2: Citizen participation provides an insight into existing interests and concerns, but not a representative impression of public opinion
Thesis 3: The results of participation do not guarantee support for sustainable transformation measures.
Thesis 4: Citizen participation is a support, but not a substitute for political decisions.

However, this does not imply that citizen participation can be dispensed with! Instead, good participation can provide support by giving information and thus, for example, overcome resistance that is primarily based on a lack of knowledge. It also uses local knowledge to recognise problems and develop new ideas where necessary. Finally, it provides a forum in which wishes and concerns can be expressed and arguments exchanged. This can lead to less protest. It can help to identify lines of conflict more clearly and to better understand the causes of conflicts. Citizen participation can thus contribute to dealing with the conflicts inherent in the transformation, but it will not usually resolve them. Last but not least, citizen participation remains a democratic imperative, as citizens should be able to shape far-reaching decisions.

Results of our research in Hamburg-Ottensen (freiRaum Ottensen): Final presentation

In a joint meeting with representatives of the district office Altona in Hamburg on 7 December 2023, the research group presented the results of the data collection in connection with the freiRaum Ottensen project. FreiRaum Ottensen was one of the five projects in which surveys and interviews were conducted. The focus was on the public consultations in which the general public was able to participate. More information on the project freiRaum Ottensen and the participation formats carried out can be found here.

Selected results

The population in Ottensen largely perceives a need for improvement in transport and is relatively positive about the transport transition overall.
Around 50% of the population have heard about the participation process for freiRaum Ottensen, and around 16% have taken part. In comparison with other processes, these are relatively high figures, although the usual over-representation of people with high school diploma, men and older people can be seen despite a wide varieties of participation formats offered to different target groups.
The discussion during the different participation formats was perceived as constructive and respectful, although conflicts and gaps in the representation of all interests were acknowledged.
In this project, the policy process was comparatively open to citizens and participants were able to shape the content of the planning outcome.
For around a third of the population and half of the participants, the participation process had an influence on their satisfaction with the district authority. However, this influence was not always positive: for example, one in four participants was more satisfied with the district authority at the end, but just as many reported less satisfaction.
Two thirds of the population rated the adopted measures as positive.

AI for the evaluation of participation? The potential of language models to recognise modes of transport in participation contributions

In this article in the journal Internationales Verkehrswesen, Laura Mark, Julia Romberg and Tobias Escher present a language model that can be used to reliably recognise modes of transport in participation contributions. They show that supervised machine learning can usefully support the evaluation of participation contributions in mobility-related online participation processes.

Summary

Consultations are an important part of transport planning and can help to integrate knowledge from the public into the planning process. However, online formats in particular often result in large volumes of contributions, the thorough evaluation of which is resource-intensive. It is hoped that the use of AI will support this.

The language model presented in this article is based on the concept of supervised machine learning for text classification. Pre-trained models are re-fined using smaller data sets. In this way, a model can be adapted to a specific area of application, such as mobility-related consultation processes.

A pre-trained German-language version of the high-performance RoBERTa language model was used as a starting point. Using a categorisation scheme that mainly distinguishes between the modes of transport mentioned, 1,700 contributions from seven transport planning consultation processes were manually coded. The resulting data was used partly as training data for fine-tuning the language model and partly for evaluation.

Results

Overall, it was shown that language models already available today are suitable for supporting the evaluation of consultation processes in practice. The language model developed here for recognising the modes of transport can serve as the basis for a specific application in municipal planning practice.
The post-trained RoBERTa language model is very effective at assigning the appropriate modes of transport. The model presented by us can always reliably assign well over 90% of the entries correctly to the modes of transport they contain.
For the processes on whose contributions the model had been trained, an average of 97% of the categories could be correctly assigned (on a separate test set). For contributions from other transport-related participation procedures, the appropriate modes of transport could still be assigned very reliably with an accuracy of 91 to 94%.
The performance of the model therefore hardly deteriorates when it is applied to previously unknown data from mobility-related participation procedures. This means that manual coding in advance can be omitted, at least for similarly structured participation procedures, which significantly reduces the effort involved.

The political shaping of the sustainability transformation: participatory and ecological?

In this article in regierungsforschung.de, the academic online magazine of the NRW School of Governance, Tobias Escher explores the question of whether the participation formats required for a participatory development of the transformation to a more sustainable society can also be implemented in an ecologically sustainable manner. In other words, the question is how the principle of (ecologically) sustainable governance can be upheld in the democratically important area of political participation.

Abstract

The transformation to a sustainable society can only succeed through the involvement of all stakeholders. At the same time, sustainable governance requires that these participation processes also fulfil the requirements of sustainability. Based on a systematic discussion of the greenhouse gas emissions generated by various political participation formats, this article argues that in view of the functional and normative significance of political participation, its environmental footprint does usually not contradict the demand for sustainable governance.

Key findings

The implementation of participation formats generates greenhouse gas emissions due to the energy required, the mobility of the participants and, where applicable, catering and accommodation. Crucially, the level of emissions depends on whether the formats are held in person or digitally (see table below).
For local face-to-face formats, the emissions from the event venue and mobility of participants are comparatively low and only amount to around 2kg of CO₂-equivalents per person in the scenario analysed. The emissions increase considerably as soon as participants have to travel further (using fossil-fuelled transport) – in the underlying scenario by a factor of twelve to 24kg. This is roughly equivalent to the average emissions from a 100km car journey.
In contrast, online participation formats only generate very low emissions (around 0.3kg per person in the scenario). Nevertheless, the choice of participation formats cannot be based solely on their short-term ecological costs, but must also take into account normative requirements for inclusion and popular control. Digital participation formats in particular represent significant barriers to participation for already disadvantaged population groups (see also our DigiBeSt-report).
Overall, participation has an ecological footprint, but this is generally justified by functional and normative considerations because after all, governance should not only be sustainable, but above all democratic!

Is that fair? An evaluation tool for local mobility measures

In this article in the journal Internationales Verkehrswesen, Laura Mark, Annika Busch-Geertsema, Jessica LeBris, Gesa Matthes and Kerstin Stark present a practical approach to assess the justice of transport measures in various dimensions. The approach and the article were developed in the context of the working group “Mobilität, Erreichbarkeit und soziale Teilhabe” of the Academy for Spatial Development in the Leibniz Association (ARL).

Summary

This paper presents a practical tool for taking a systematic “second look” at mobility transition measures through the lens of justice. It can be used for conceptual support during planning and implementation, for reflection during or after the process as well as ongoing monitoring. Three dimensions of justice can be used to analyse which population-groups benefit from these measures. The dimensions used are distributive justice, recognition of different realities of life and procedural justice, which have been further differentiated and combined in an easy-to-use matrix.

To differentiate the recognition of different realities of life, the Persona approach is employed. In a Persona, specific characteristics are combined that can influence and restrict mobility options, decisions, and activity chains. The article proposes a system for developing custom Personas, but the Personas already developed by the authors can also be used for the application.

The article provides a detailed presentation of the dimensions of justice and the Persona approach. It can be downloaded here:

Annotation and Provision of Datasets

As part of our project, we worked on the manual annotation of a large number of datasets with the aim of supporting the development of AI methods for evaluating public participation contributions.

Supervised machine learning requires training datasets in order to learn patterns related to the respective codings. In the area of citizen participation, there is a lack of comprehensively coded German-language datasets. In order to meet this need, we have therefore worked on annotating German-language participation processes from the field of mobility according to four dimensions:

Firstly, we have thematically classified contributions according to modes of transportation, other requirements for public space, and defects that need to be fixed immediately.
Second, we coded processes by argumentative sentences and divided them into premises and conclusions.
Thirdly, we have assigned argumentative units of meaning to how concrete they are.
Fourthly, we have coded textual location information.

A more detailed description of the datasets – as of June 2022 – can be found in our publication: Romberg, Julia; Mark, Laura; Escher, Tobias (2022, June). A Corpus of German Citizen Contributions in Mobility Planning: Supporting Evaluation Through Multidimensional Classification. Since then, we have continued to work on the thematic coding of the datasets and revised our scheme of modes of transport.

The following table shows the current status of annotation and is updated on an ongoing basis (in German): Google-Sheet
