- Connected vehicles generate new data streams that present promising opportunities for policymakers to monitor and learn from events and behavior. To explore what we can learn from how public entities leverage ubiquitous data streams for policy development and enforcement, we draw on a case study of the standard Mobility Data Specification (MDS) and its use by cities to regulate E-scooter operators. Our findings suggest that (1) the richness of real-time data changes the speed of policy revision, (2) data access enables moving some micro-decisions to the edge, and (3) policy will be formulated as fixed or flexible with different amendment rules.

- In recent years, the e-scooter has gained exceptional worldwide adoption, and their hybrid vehicle design has placed them in a legislative void. To this end, many cities are developing local regulations to govern and follow-up e-scooter operations within their jurisdiction. As e-scooters are equipped with hardware like SIM cards, GPS sensors, and accelerometers, the vehicles can both collect and act on digital information. Increasingly, cities thus draw on these capabilities using the Mobility Data Specification (MDS) as a soft digital infrastructure to e.g., express local regulations and collect operator data for compliance purposes. This paper uses interview data from European and U.S. cities, e-scooter operators, and systems integrators to provide an overview of the history and components of MDS. The paper also presents cities’ current uses and emerging challenges regarding using MDS for regulation, compliance monitoring, as well as data analytics for physical infrastructure planning.

The Design of Open Platforms: Towards an Emulation Theory
- 2023

Konferensbidrag (refereegranskat)abstract
- The enrolment of third-party developers is essential to leverage the creation and evolution of data ecosystems. When such complementary development takes place without any organizational consent, however, it causes new social and technical problems to be solved. In this paper, we advance platform emulation as a theoretical perspective to explore the nature of such problem-solving in the realm of open platforms. Empirically, our analysis builds on a 10-year action design research effort together with a Swedish authority. Its deliberate change agenda was to transform unsolicited third-party development into a sanctioned data ecosystem, which led to a live open platform that is still in production use. Theoretically, we synthesize and extend received theory on open platforms and offer novel product and process principles for this class of digital platforms.

- Within the Horizon 2020 project LEON-T (Low particle Emissions and lOw Noise Tyres), one of the aims is to investigate the effect on cardiovascular health from the effect on sleep of noise from heavy vehicle (EU class N2 and N3) tyres. Effects of noise on sleep are investigated by performing sleep experiments in a controlled lab environment where participants sleep several nights subjected to different traffic noise scenarios. The traffic noise scenarios have been constructed using synthesized tyre noise allowing for variation in parameters such as tyre tread pattern design, tyre air cavity resonance, traffic flow properties and distance between traffic noise source and receiver. The synthesized scenarios have been designed in close cooperation with experts on health effects from noise in order to expose the participants to such stimuli that provide relevant and valid responses. For the initial sleep experiment properties such as high or low traffc flow, individual vehicle noise level and level of perceptually salient tonal components in the synthesized tyre sound are investigated. This paper describes the synthesized vehicle sounds and the traffic noise scenario design process for the scenario used in the first sleep experiment.

Good sound environment in green areas modify road-traffic noise annoyance at home
- 2009

Konferensbidrag (populärvet., debatt m.m.)abstract
- There has been a growing recognition among noise researchers that natural elements and natural areas of the built environment have potentials to reduce annoyance due to traffic noise. It has been suggested that presence of vegetation (e.g., trees, bushes, grass, flowers) contributes to an aesthetically pleasing environment, which influence overall residential satisfaction and people?s perception of the noise. Other expected benefits of natural elements/areas are prevention or modification of adverse effects of work-, personal-, or environmental stress (e.g., noise) through restoration processes. Within the large TVANE-project, the present study examined the effect of green areas (park or similar at walking distance) on noise responses in residential settings (n=468) exposed to road traffic noise (LAeq,24h 45 to 65 dB). A binary multiple logistic regression analysis, with sound exposure as the prime variable assumed to predict general noise annoyance at home, indicated that presence of green areas, a closer distance to it from the subject?s home, and perceived green-area characteristics (good sound environment, high attractiveness and potentials for recreational activities) significantly lowered noise annoyance. The results suggest that the exposure-response relationship between noise and annoyance is influenced by access to nearby green areas provided that they have good environmental quality, particularly regarding the perceived sound environment

Toward Citizen-Centered Digital Government : Design Principles Guided Legacy System Renewal in A Swedish Municipality
- 2024
-
Ingår i: Proceedings of the 57th Hawaii International Conference on System Sciences. - : ScholarSpace. - 1530-1605 .- 2572-6862. - 9780998133171 ; , s. 1963-1972

Konferensbidrag (refereegranskat)abstract
- Transformation towards a digital government imposes significant demands on the capabilities of legacy infrastructure. We closely followed a Swedish municipality that designed and implemented a solution to improve the building permit application process with an aim to improve citizen service. We developed six design principles (DPs): availability, timeliness, actionability, transparency, personalization, and generalizability. These DPs guide the solution design and provide a seamless application experience for citizens and business owners. We also discuss the reasoning behind the design choices and the implications of the solution. The artifact encompasses understanding citizens’ needs, identifying constraints of the legacy systems, formulating design principles, and developing architectural designs. However, addressing the social aspects of legacy systems, such as organizational culture change, necessitates additional steps, and is worth investigation in future studies.

Konferensbidrag (refereegranskat)abstract
- This paper compiles, evaluates and analyses information from different data sources on accidents and health, road transport and economic performance in a comprehensive manner to assess the size and impact of road accidents and injuries in regions under increasing motorization. Strategies based on global road safety improvement experiences are presented. In addition the paper aims at discussing a way forward by indicating opportunities and countermeasures that could be implemented to achieve a new level of safety in these regions. The data used comes from e.g. World Health Organization (WHO) and World Bank. Estimations on costs due to road transport injuries are presented. The results clearly demonstrate that road safety is causing large problems and costs with an enormous impact on the well-being of people, economy and productivity. For example, according to our analysis, the loss to the economy in Latin America is more than 130 billion US$ or 2.8 % of GDP. In many of low and middle-income countries the yearly number of fatalities and injuries is still increasing. Vulnerable road users (pedestrians, cyclists and motor cyclists) are particularly at risk. Reliable accident data are imperative to determine evidence based intervention strategies and monitor the success of these interventions and analyses. When comparing data it is clear that there are large problems in official statistics in several countries. The lack of good high quality accident data should, however, not be an excuse to postpone measures. Future trends in road transport and lessons learned from best practices in high-income countries are reviewed. The paper also proposes measures beyond the Decade of Action Plan for Road Safety 2011-2020, with respect to vulnerable road users, infrastructure, vehicle technology and truck and bus safety and discusses the implications for road safety in the UN’s new Sustainable Development Goals.
