Free floating electric scooters is a relatively new phenomena in many cities across the world and despite the Covid-19-pandemic, electric scooters are growing in popularity. There are however mixed opinions on whether electric scooters are environmentally friendly or not and if they are an option for municipalities to utilize in their planning towards more sustainable cities or not. Laws are also lacking for regulating this new means of transport. This study aims to examine how municipalities can plan for electric scooters in their traffic planning as well as examining if electric scooters work according to the municipalities’ visions for their future traffic planning. This study also aims to map out what Swedish cities have electric scooters today and examine what characteristics these cities have. The study has been conducted through interviews with two Swedish municipalities, one Norwegian municipality and one provider of free floating electric scooters. A literature review of several municipalities’ planning and strategy documents has been carried out as well. Findings show that free floating electric scooters exist in the most populous municipalities in Sweden. The municipalities have a high share of students and young people in the ages 18-35, which is the age group that tend to use electric scooters the most. The municipalities have a lower amount of days with snow-cover than the national average. Findings also show that municipalities are positive towards free floating electric scooters and think that they fit in with the overall visions for the municipalities’ planning.

The rapid growth and development of cities have brought new mobility challenges, which the emergence of micro-mobility solutions, such as Personal Mobility Vehicles, has addressed. However, the increase in the use of these vehicles has also led to a rise in the number of accidents and injuries due to the inadequate use of protective equipment. Consequently, the sales of safety apparel have increased (Smith, 2022), creating a more competitive market where marketing strategies have become essential to successfully sell the product. This study aims to investigate the purchase behavior of safety apparel products, using the Theory of Planned Behavior as a framework to analyze the factors that affect the intentions of consumers to buy safety apparel. The research considered both product and societal factors that motivate or discourage the purchase of safety apparel. The results of the study revealed that the characteristics of the safety apparel product were the most significant factor that motivated the purchase. Consumers preferred discreet aesthetics and dark colors; low prices were also important factors. In addition, fashion, the influence of specialists in stores and on social networks, and the role of authorities were also found to be significant factors. However, the ability of buyers to carry out this behavior was subject to product compatibility, affordability, and availability. The findings of this research will help manufacturers and retailers to develop better marketing strategies that will increase the effectiveness of campaigns and enhance the motivation, importance, and priority to buy safety apparel. The study's contributions also have implications for other organizations that market safety-related products or want to promote their use. Overall, this study sheds light on the understanding of safety apparel customers and aims to contribute to improving marketing strategies in the safety apparel industry and promoting the safety culture among city commuters.

In this study, travel behavior for the users of E-scooter is analyzed based on survey questions. The main purpose of the study is to understand the nature of E-scooters users and their preferences as well as analyzing their trip parameters. The survey was designed to cover most ofthe behavioral influential factors. To represent the motives and barriers towards E-scooter adoption in greater Stockholm. it was sectioned into demographic data, general travel preferences, E-scooter choice preferences, last trip parameters and general discussion questions. Findings of this study suggested that E-scooters are mainly used by residents aged between 18-24. In Stockholm, public transportation facilities are very accessible and affordable than other private transportation modes. Travel time and travel cost were highly evaluated by the users and were considered as deciding criteria prior to making any trip in Stockholm. Findings suggested that trips made by E-scooters are mainly for fun and leisure rather than commuting and services. However, regarding normal trips, it was found that walking replaced the use of E-scooters more often. Historical data was used to validate and support the survey findings. Survey questions did not consider questions regarding impacts of COVID-19 on travel behaviours as well as the changes in travel patterns. Furthermore, the absence of highlights on research areas such as safety which covers the adoption of risky behaviours (i.e., driving on sidewalks, driving opposing traffic flow) and helmet use. The tool was used for research purposes was ‘Questionpro’. / I denna studie analyseras resebeteendet för användarna av E-scooter baserat på enkätfrågor. Huvudsyftet med studien är att förstå E-scooters användares natur och deras preferenser samt att analysera deras tripparametrar. Undersökningen var utformad för att täcka de flesta av debeteendemässiga inflytelserika faktorerna. Att representera motiv och barriärer mot e-scooteradoption i större Stockholm. den delades in i demografisk data, allmänna resepreferenser, val av E-scooter-val, parametrar för sista resan och allmänna diskussionsfrågor. Resultaten av denna studie föreslog att E-skotrar huvudsakligen används av invånare i åldrarna 18-24. I Stockholm är anläggningar för kollektivtrafik mycket tillgängliga och prisvärda än andra privata transportsätt. Restid och resekostnader utvärderades mycket av användarna och ansågs vara avgörande kriterier innan de gjorde en resa i Stockholm. Resultaten föreslog att resor med e-skotrar främst är för skoj och fritid snarare än pendling och tjänster. När det gäller normala resor fann man dock att promenader ersatte användningen av E-skotrar oftare. Historiska data användes för att validera och stödja undersökningsresultaten.

Wireless networking introduces a whole range of challenges to the traditional TCP/IP network. In particular, IP address the issue of overloading because IP addresses are used as a network locator and an end point identity in the different layers in an OSI model. Even though Mobile IP is widely deployed, it has significant problems relating to performance and security. The Host Identity Protocol (HIP) provides secure mobility management by solving the IP address overloading from another angle. It restructures the TCP/IP model and introduces a new layer and a new namespace. The performance of HIP has proven to be better than Mobile IP and also opens a range of new research opportunities. This dissertation proposes and analyses a new step-stone solution from the Mobile IP-based network into a HIP-based network. The main advantage of this new solution is that much less change is required to the operating system kernel of the end point compared to a full HIP implementation. The new step-stone solution allows Mobile IP to use some HIP features to provide better security and handover performance. This dissertation also proposes several new and novel HIP-based wireless communication network architectures. An HIP-based heterogeneous wireless network architecture and handover scheme has been proposed and analysed. These schemes limit the HIP signalling in the wireless network if no communication to external networks is needed. Beside the network architecture modification, the hybrid Session Initial Protocol (SIP) and HIP-based Voice over IP (VoIP) scheme is proposed and analysed. This novel scheme improves the handover latency and security. This dissertation also proposes and analyses a new and novel extension to HIP, a HIP-based micro-mobility management, micro-HIP (mHIP). mHIP provides a new secure framework for micro-mobility management. It is a more complete HIP-based micro-mobility solution than any other proposed in existing studies. mHIP improves the intra-domain handover performance, the security, and the distribution of load in the intra-domain handover signalling. The new work presented opens up a number of very interesting research opportunities.
